Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	Description of Business
	We are a leading global provider of engineering and manufacturing services for high-performance products and high-cost-of failure applications used primarily in the aerospace, defense industrial, natural resources, medical and other industries. Our subsidiaries are organized into two strategic businesses; Ducommun LaBarge Technologies (“DLT”) and Ducommun AeroStructures (“DAS”), each of which is a reportable operating segment. DLT designs, engineers and manufactures high-reliability products used in worldwide technology-driven markets including aerospace and defense, natural resources, industrial and medical and other end-use markets. DLT’s product offerings range from prototype development to complex assemblies. DAS designs, engineers and manufactures large, complex contoured aerospace structural components and assemblies and supplies composite and metal bonded structures and assemblies. DAS’s products are used on commercial aircraft, military fixed-wing aircraft and military and commercial rotary-wing aircraft. All reportable operating segments follow the same accounting principles.
	Basis of Presentation
	The consolidated financial statements include the accounts of Ducommun Incorporated and its subsidiaries (“Ducommun,” the “Company,” “we,” “us” or “our”), after eliminating intercompany balances and transactions.
	Our fiscal quarters end on the Saturday closest to the end of March, June and September for the first three fiscal quarters of each year, and ends on December 31 for our fourth fiscal quarter.
	In the opinion of management, all adjustments, consisting of recurring accruals, have been made that are necessary to fairly state our consolidated financial position, results of operations, comprehensive income (loss) and cash flows in accordance with accounting principles generally accepted in the United States of America (“GAAP”).
	Use of Estimates
	Certain amounts and disclosures included in the consolidated financial statements required management to make estimates and judgments that affect the amounts of assets, liabilities (including forward loss reserves), revenues and expenses, and related disclosures of contingent assets and liabilities. These estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from these estimates.
	Reclassifications
	Certain prior period amounts have been reclassified to conform to current year’s presentation.
	Restatement of Previously Issued Consolidated Financial Statements
	We have restated our consolidated financial statements as of December 31, 2013, and for the years ended December 31, 2013 and 2012 and our unaudited quarterly financial information for the first three quarters in the year ended December 31, 2014 and for each of the quarters in the year ended December 31, 2013, to correct errors in prior periods primarily related to (i) a long-term contract following the discovery of misconduct by employees in the recording of direct labor costs to the contract from 2009 through the third quarter 2014 which resulted in the identification of a forward loss provision that should have been recorded in 2009 and the impact on subsequent periods of adjustments to the forward loss provision based on information available at the time; and (ii) the year end reconciliation of income taxes payable and deferred tax balances identified errors primarily in 2013, 2012, and 2011. In addition, the restated amounts include previously identified and disclosed immaterial adjustments. See Note 2 for additional information.
	Cash Equivalents
	Our cash accounts are not reduced for checks written until the checks are presented for payment and paid by our bank. Cash equivalents consist of highly liquid instruments purchased with original maturities of three months or less. These assets are valued at cost, which approximates fair value, which we classify as Level 1. See Fair Value below.
	Revenue Recognition
	Except as described below, we recognize revenue, including revenue from products sold under long-term contracts, when persuasive evidence of an arrangement exists, the price is fixed or determinable, collection is reasonably assured and delivery of products has occurred or services have been rendered.
	We have a significant number of contracts for which net revenues are accounted for under the percentage-of-completion method using the units of delivery as the measure of completion. The percentage-of-completion method requires the use of assumptions and estimates related to the contract value, the total cost at completion, and measurement of progress toward completion. These contracts are primarily fixed-price contracts that vary widely in terms of size, length of performance period and expected gross profit margins.
	We also recognize revenue on the sale of services (including prototype products) based on the type of contract: time and materials, cost-plus reimbursement and firm-fixed price. Revenue is recognized (i) on time and materials contracts as time is spent at hourly rates, which are negotiated with customers, plus the cost of any allowable materials and out-of-pocket expenses, (ii) on cost-plus reimbursement contracts based on direct and indirect costs incurred plus a negotiated profit calculated as a percentage of cost, a fixed amount or a performance-based award fee, and (iii) on fixed-price contracts on the percentage-of-completion method measured by the percentage of costs incurred to estimated total costs.
	Provision for Estimated Losses on Contracts
	We record provisions for the total anticipated losses on contracts considering total estimated costs to complete the contract compared to total anticipated revenues in the period in which such losses are identified. The provisions for estimated losses on contracts require management to make certain estimates and assumptions, including those with respect to the future revenue under a contract and the future cost to complete the contract. Management's estimate of the future cost to complete a contract may include assumptions as to improvements in manufacturing efficiency, reductions in operating and material costs, and our ability to resolve claims and assertions with our customers. If any of these or other assumptions and estimates do not materialize in the future, we maybe required to record additional provisions for estimated losses on contracts.
	In the fourth quarter of 2013, we recorded a charge in the DAS segment for the estimated cost to complete of $5.2 million, consisting of $3.9 million for the Embraer Legacy 450/500 aircraft contracts, and $1.3 million for the Boeing 777 wing tip contract. The charges result from difficulties in achieving previously anticipated cost reductions, including delays in transferring work to our lower-cost Guaymas, Mexico facility. The charge for the Embraer Legacy 450/500 contracts also reflects estimated cost overruns for customer driven changes on both the development and production phases of the contracts, for which we have asserted claims with Embraer. Recognition of additional losses in future periods continues to be a risk and will depend upon numerous factors, including our sales forecast, our ability to achieve forecasted cost reductions and our ability to resolve claims and assertions with our customers. The $5.2 million charge was recorded as part of cost of goods sold in the Company’s results of operations. The charge increased accrued liabilities by $4.2 million and other long-term liabilities by $1.0 million on our balance sheet.
	Allowance for Doubtful Accounts
	We maintain an allowance for doubtful accounts for estimated losses from the inability of customers to make required payments. The allowance for doubtful accounts is evaluated periodically based on the aging of accounts receivable, the financial condition of customers and their payment history, historical write-off experience and other assumptions, such as current assessment of economic conditions.
	Inventories
	Inventories are stated at the lower of cost or market, cost being determined on a first-in, first-out basis. Market value for raw materials is based on replacement costs, and is based on net realizable value for other inventory classifications. Inventoried costs include raw materials, outside processing, direct labor and allocated overhead, adjusted for any abnormal amounts of idle facility expense, freight, handling costs, and wasted materials (spoilage) incurred. Costs under long-term contracts are accumulated into, and removed from, inventory on the same basis as other contracts. We assess the inventory carrying value and reduce it, if necessary, to its net realizable value based on customer orders on hand, and internal demand forecasts using management’s best estimates given information currently available. We maintain an allowance for potentially excess and obsolete inventories and inventories that are carried at costs that are higher than their estimated net realizable values. In the fourth quarter of 2013, we recorded a charge of approximately $1.9 million in the DAS segment for the Embraer Legacy 450/500 aircraft contracts. The charge result from difficulties in achieving previously anticipated cost reductions, and estimated cost overruns driven by customer changes for both the development and production phases of the contracts.
	We net advances from customers related to inventory purchases against inventories in the consolidated balance sheets.
	Production Cost of Contracts
	Production cost of contracts includes non-recurring production costs, such as design and engineering costs, and tooling and other special-purpose machinery necessary to build parts as specified in a contract. Production costs of contracts are recorded to cost of goods sold using the units of delivery method. We review long-lived assets within production costs of contracts for impairment on an annual basis (in the fourth quarter for us) or when events or changes in circumstances indicate that the carrying value of our long-lived assets may not be recoverable. An impairment charge is recognized when the carrying value of an asset exceeds the projected undiscounted future cash flows expected from its use and disposal. In the fourth quarter of 2013, we recorded an impairment charge in the DAS segment on production costs of contracts of $7.0 million, consisting of $5.7 million for the Embraer Legacy 450/500 aircraft contracts, and $1.3 million for the Boeing 777 wing tip contract. The impairment charge reflects a determination that the production cost of contracts for the Boeing 777 wing tip contract and the Embraer Legacy 450/500 contracts are not recoverable since these contracts are estimated to be unprofitable during their remaining terms. The impairment charge represents the entire remaining balance of production cost of contracts for these contracts. The $7.0 million charge was recorded as part of cost of goods sold in the Company’s results of operations and a reduction in production cost of contracts on the Company’s balance sheet. As of December 31, 2014 and 2013, production costs of contracts were approximately $11.7 million and $11.6 million, respectively.
	Property and Equipment and Depreciation
	Property and equipment, including assets recorded under capital leases, are recorded at cost. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the related assets, or the lease term if shorter for leasehold improvements. Repairs and maintenance are charged to expense as incurred. We evaluate long-lived assets for recoverability considering undiscounted cash flows, when significant changes in conditions occur, and recognize impairment losses if any, based upon the fair value of the assets.
	Fair Value
	Assets and liabilities that are measured, recorded or disclosed at fair value on a recurring basis are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1, the highest level, refers to the values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant observable inputs. Level 3, the lowest level, includes fair values estimated using significant unobservable inputs.
	Goodwill and Indefinite-Lived Intangible Asset
	Goodwill is tested for impairment utilizing a two-step method. In the first step, we determine the fair value of the reporting unit using expected future discounted cash flows and market valuation approaches considering comparable Company revenue and Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”) multiples. If the carrying value of the reporting unit exceeds its fair value, we then perform the second step of the impairment test to measure the amount of the impairment loss, if any. The second step requires fair valuation of all the reporting unit’s assets and liabilities in a manner similar to a purchase price allocation, with any residual fair value being allocated to goodwill. This residual fair value of goodwill is then compared to its carrying value to determine impairment. An impairment charge will be recognized only when the estimated fair value of a reporting unit, including goodwill, is less than its carrying value.
	We review our indefinite-lived intangible asset for impairment on an annual basis or when events or changes in circumstances indicate that the carrying value of our intangible asset may not be recoverable. We may first assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test. Impairment indicators include, but are not limited to, cost factors, financial performance, adverse legal or regulatory developments, industry and market conditions and general economic conditions. If the carrying amount of the indefinite-lived intangible asset exceeds its fair value, we would recognize an impairment loss in the amount of such excess.
	Income Taxes
	Deferred tax assets and liabilities are recognized, using enacted tax rates, for the expected future tax consequences of temporary differences between the book and tax bases of recorded assets and liabilities, operating losses and tax credit carryforwards. Deferred tax assets are evaluated quarterly and are reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized.
	Tax positions taken or expected to be taken in a tax return are recognized when it is more-likely-than-not to be sustained upon examination by taxing authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement.
	Litigation and Commitments
	In the normal course of business, we are defendants in certain litigation, claims and inquiries, including matters relating to environmental laws. In addition, we make various commitments and incur contingent liabilities. Management’s estimates regarding contingent liabilities could differ from actual results.
	Environmental Liabilities
	Environmental liabilities are recorded when environmental assessments and/or remedial efforts are probable and costs can be reasonably estimated. Generally, the timing of these accruals coincides with the completion of a feasibility study or our commitment to a formal plan of action. Further, we review and update our environmental accruals as circumstances change and/or additional information is obtained that reasonably could be expected to have a meaningful effect on the outcome of a matter or the estimated cost thereof.
	Accounting for Stock-Based Compensation
	We measure and recognize compensation expense for share-based payment transactions to our employees and non-employees at their estimated fair value. The expense is measured at the grant date, based on the calculated fair value of the share-based award, and is recognized over the requisite service period (generally the vesting period of the equity award). The fair value stock options are determined using the Black-Scholes valuation model, which requires assumptions and judgments regarding stock price volatility, risk-free interest rates, expected options terms, and options that are expected to be forfeited. The fair value of unvested stock awards is determined based on the closing price of the underlying common stock on the date of grant. Management’s estimates could differ from actual results.
	Other Intangible Assets
	We amortize purchased other intangible assets with finite lives over the estimated economic lives of the assets, ranging from three to eighteen years generally using the straight-line method. The value of other intangibles acquired through business combinations has been estimated using present value techniques which involve estimates of future cash flows. We evaluate other intangible assets for recoverability considering undiscounted cash flows, when significant changes in conditions occur, and recognizes impairment losses, if any, based upon the estimated fair value of the assets.
	Earnings Per Share
	Basic earnings per share are computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding in each period. Diluted earnings per share are computed by dividing income available to common shareholders plus income associated with dilutive securities by the weighted-average number of common shares outstanding, plus any potential dilutive shares that could be issued if exercised or converted into common stock in each period.
	The net earnings and weighted-average number of common shares outstanding used to compute earnings per share were as follows:

Recent Accounting Pronouncements
New Accounting Guidance Adopted in 2014
In July 2013, the FASB issued Accounting Standards Update 2013-11, “Income Taxes (Topic 740)” (“ASU 2013-11”), which required the netting of unrecognized tax benefits against a deferred tax asset for a loss or other carryforward that would apply in settlement of the uncertain tax positions. This guidance was effective for fiscal years beginning after December 15, 2013, which is our fiscal year 2014, with early adoption permitted. The adoption of this standard at the beginning of our fiscal year 2014 reduced deferred tax assets by approximately $0.7 million.
In February 2013, the FASB issued ASU 2013-04, “Liabilities (Topic 405)” (“ASU 2013-04”), which provided guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date, except for obligations addressed within existing guidance in GAAP. The new guidance was effective for us beginning January 1, 2014. Early adoption was permitted. The adoption of this standard at the beginning of our fiscal year 2014 did not have a material impact on our consolidated financial statements.
Recently Issued Accounting Standards
In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“ASU 2014-15”), which defines management’s responsibility to evaluate whether there is substantial doubt about a company’s ability to continue as a going concern. ASU 2014-15 also provide principles and definitions that are intended to reduce diversity in the timing and content of disclosures in the financial statement footnotes. The new guidance is effective for annual periods ending after December 15, 2016, which will be our year ending December 31, 2016, and interim periods beginning after December 15, 2016, which will be our interim period beginning January 1, 2017. Early adoption is permitted. We are evaluating the impact of this standard but currently do not anticipate it will have a significant impact on our consolidated financial statements.
In June 2014, the FASB issued ASU 2014-12, “Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide that a Performance Target Could be Achieved after the Requisite Service Period” (“ASU 2014-12”), which requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. Thus, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The new guidance is effective for us beginning January 1, 2016. Early adoption is permitted. We currently do not anticipate the adoption of this standard will have a material impact on our consolidated financial statements.
In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. It requires entities to exercise judgment when considering the terms of the contract(s) which include (i) identifying the contract(s) with the customer, (ii) identifying the separate performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the separate performance obligations, and (v) recognizing revenue when each performance obligation is satisfied. Thus, it depicts the transfer of promised goods or services to customers in an amount that reflects the consideration an entity expects to receive in exchange for those goods or services. Companies have the option of applying the provisions of ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying this guidance recognized at the date of initial application. Early adoption is not permitted. The new guidance is effective for us beginning January 1, 2017. We are currently evaluating the method and impact that adopting this new accounting standard will have on our consolidated financial statements.

Accounting Changes and Error Corrections [Abstract]
Restatement	Restatement
	We have restated our consolidated financial statements as of December 31, 2013, and for the years ended December 31, 2013 and 2012 and our unaudited quarterly financial information for the first three quarters in the year ended December 31, 2014 and for each of the quarters in the year ended December 31, 2013, to correct errors in prior periods primarily related to (i) a long-term contract (“Contract”) following the discovery of misconduct by employees in the recording of direct labor costs to the Contract from 2009 through the third quarter 2014 which resulted in the identification of a forward loss provision that should have been recorded in 2009 and the impact on subsequent periods of adjustments to the forward loss provision based on information available at the time (“Forward Loss Adjustments”); and (ii) the year end reconciliation of income taxes payable and deferred tax balances identified errors primarily in 2013, 2012, and 2011 (“Tax Adjustments”). The misconduct and its related financial impact were concealed from our senior management, internal auditors, and external auditors.
	The Forward Loss Adjustments were based on certain assumptions and estimates. To determine the loss on the Contract, we estimated the number of units we would have expected to ship over the life of the Contract at inception of the Contract using external market industry data for fiscal years 2009, 2010, 2011, 2012, and 2013. We used data obtained directly from the customer for 2014 and 2015. The total estimated costs at any given point in time would typically include actual historical costs up to that time plus the estimated cost to produce units to be delivered. In addition, the estimated total cost for the life of the Contract includes certain inefficiencies on labor, material, and overhead costs during the initial start-up period. However, as we progress along the learning curve, the direct labor hours and overhead rates are expected to decrease as we gain technical knowhow and efficiency in producing the product. As a result of the misconduct by the employees in the recording of direct labor hours to the Contract, the historical actual direct labor hours charged to the Contract were inaccurate. As a result, we estimated the costs to complete future units at the end of each period based on an estimate of the direct labor hours chargeable to the Contract, including consideration of anticipated learning curve efficiencies that would decrease the direct labor hours over the remaining term of the Contract. Further, we used the actual direct labor hours incurred by the employees assigned to the Contract as a basis for projecting future hours, less an estimate of the time not allocable to the Contract. Using this model, we calculated the Forward Loss Adjustments from the inception of the Contract in 2009 through the expected life of the Contract. As a result of the Forward Loss Adjustments, cost of goods sold increased (decreased) approximately $6.7 million in 2009, $1.3 million in 2010, $(0.3) million in 2011, $(2.2) million in 2012, $(0.9) million in 2013, and $(0.8) million in the nine months ended September 27, 2014.
	The Tax Adjustments were necessary as a result of certain calculation errors. The Tax Adjustments resulted in a net decrease to income tax expense of approximately $0.9 million in 2013 and zero in 2012. The Tax Adjustments in 2011 resulted in a reduction to the carrying value of goodwill totaling approximately $4.0 million due to a calculation error in the original purchase price allocation and subsequent performance of step 2 of our annual goodwill impairment analysis related to deferred income taxes and thus, (i) reduced deferred income taxes by approximately $2.7 million and (ii) generated a pre-tax goodwill impairment charge of approximately $1.4 million. Further, the Tax Adjustments in 2011 reduced deferred tax assets by approximately $1.6 million that were established as a result of shared-based compensation expenses recorded previously and should have been reduced as the tax deductions were utilized. Moreover, the restated amounts include previously identified and disclosed immaterial adjustments.
	We evaluated the cumulative impact of these items on prior periods in accordance with the guidance in ASC 250-10, Accounting Changes and Error Corrections, relating to SEC Staff Accounting Bulletin No. 99, Materiality (“SAB 99”) and SAB No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements (“SAB 108”), and we concluded these errors were in the aggregate material to the prior reporting periods, and therefore, restatement of previously filed financial statements was necessary to our previously issued 2013, 2012, 2011, and 2010 financial statements.
	The adjustments related to the years prior to 2012 are reflected in the beginning retained earnings for 2012. The cumulative impact of these adjustments decreased retained earnings by approximately $7.0 million, net of tax, at the beginning of 2012.
	The account balances labeled “As Reported” in the following tables for the years ended December 31, 2013 and 2012 represent the previously reported audited balances in our Annual Report on Form 10-K (“Form 10-K”) for the year ended December 31, 2013. Certain prior period amounts have been reclassified to conform to current year’s presentation. The effects of these prior period errors on the consolidated financial statements are as follows (in thousands, except per share data):

	In 2014, we made voluntary principal prepayments of approximately $42.6 million on our senior secured term loan as discussed below. At December 31, 2014, we had approximately $58.5 million of available borrowing capacity, as discussed below.
	Senior Secured Term Loan and Senior Secured Revolving Credit Facility (“Credit Facilities”)
	We obtained our senior secured term loan (“Term Loan”), which matures on June 28, 2017, and entered into a $60.0 million senior secured revolving credit facility (“Revolving Credit Facility”), which matures on June 28, 2016, in connection with the LaBarge Acquisition. The Credit Facilities provides the option of choosing the London Interbank Offered Rate (“LIBOR” rate), or the Alternate Base Rate. The LIBOR rate may be for a one-, two-, three- or six-month period chosen by us. The payment of interest coincides with the LIBOR period we select.
	On March 28, 2013, we executed an amendment to our Credit Facilities which completed a repricing of our Term Loan and Revolving Credit Facility. The repricing reduced the interest rate spread on the Term Loan and Revolving Credit Facility by 50 basis points and the interest rate floor by 25 basis points under the LIBOR rate or the Alternate Base Rate. The LIBOR rate has a floor of 1.00% plus 3.75%. The Alternate Base Rate has a floor of 2.00% plus 2.75%. The Alternate Base Rate is the greater of the (a) Prime rate and (b) Federal Funds rate plus 0.5%. In connection with this repricing, we recognized approximately $0.5 million of financing and legal costs which were included in selling, general and administrative expenses in the first quarter of 2013.
	The Term Loan required quarterly principal payments of $0.5 million beginning on September 30, 2011 and mandatory prepayment of certain amounts of excess cash flow on an annual basis beginning 2012. In 2012, we made voluntary principal prepayments of $25.0 million on our Term Loan and eliminated all required quarterly principal payments going forward.
	The Credit Facilities are collaterized by substantially all of our assets and contain minimum Earnings before Interest, Taxes, Depreciation and Amortization (“EBITDA”) and maximum leverage covenants under certain circumstances, as well as annual limitations on capital expenditures and limitation on future disposition of property, investments, acquisitions, repurchase of stock, dividends, and outside indebtedness. In the event that a certain minimum amount is borrowed and outstanding under the Revolving Credit Facility, for so long as any such amount is outstanding, we will be required to comply with a total leverage ratio. Furthermore, our consolidated EBITDA, as defined by these Credit Facilities, as of the end of any fiscal quarter on a trailing four-quarter basis is not permitted to be less than $50.0 million. At December 31, 2014, we were in compliance with all covenants. At December 31, 2014, there were no amounts outstanding that would have triggered the leverage covenant. However, we would have been in compliance with such leverage covenant.
	On October 18, 2013, we executed an amendment to our Credit Facilities which increases the maximum leverage ratio, as defined, by 0.75 in all future periods.
	At December 31, 2014, we had approximately $58.5 million of unused borrowing capacity under the Revolving Credit Facility after deducting approximately $1.5 million for standby letters of credit. Upon the satisfaction of certain conditions, including but not limited to, the agreement of lenders to provide such facilities or commitments, we also have the option to add one or more incremental term loan facilities or increase commitments under our Credit Facility by an aggregate amount of up to $75.0 million.
	Senior Unsecured Notes
	In connection with the LaBarge Acquisition, we issued $200.0 million of senior unsecured notes (the “Notes”) with interest of 9.75% per annum, payable semi-annually on January 15 and July 15 of each year, beginning in 2012. The Notes become callable on July 15, 2015 and mature on July 15, 2018, at which time the entire principal amount is due.
	Upon a change of control, as defined, we will be required to offer to purchase all of the Notes then outstanding for cash at 101% of the principal amount plus accrued and unpaid interest, if any, on the date of purchase on the Notes. A change of control under the indenture governing the Notes may also result in an event of default under our Credit Facilities which may cause the acceleration of indebtedness outstanding thereunder, in which case, proceeds of collateral pledged to secure borrowings thereunder would be used to repay such borrowings before we repay the Notes.
	The Notes were issued by us (“Parent Company”) and guaranteed by all of our subsidiaries, other than one subsidiary (“Subsidiary Guarantors”) that was considered minor. The Parent Company has no independent assets or operations and the Subsidiary Guarantors are jointly and severally guarantee, on a senior unsecured basis, the Notes. Therefore, no condensed consolidating financial information for the Parent Company and its subsidiaries are presented.
	Promissory Note
	On December 23, 2013, we paid our $3.0 million promissory note issued in connection with the 2008 acquisition of DAS-New York, according to terms.
	Fair Value of Long-Term Debt
	The carrying amount of long-term debt approximates fair value, except for the Notes for which the fair value was approximately $213.0 million. Fair value was estimated using Level 2 inputs, based on the terms of the related debt, recent transactions and estimates using interest rates currently available to us for debt with similar terms and remaining maturities.

Stock-Based Compensation	Stock-Based Compensation
	Stock Incentive Compensation Plans
	We have two stock incentive plans. The 2007 Stock Incentive Plan (the “2007 Plan”), as amended effective March 20, 2007, and the 2013 Stock Incentive Plan (the “2013 Plan”), collectively referred to as (the “Stock Incentive Plans”), permits awards of stock options, restricted stock units, performance stock units and other stock-based awards to our officers, key employees and non-employee directors on terms determined by the Compensation Committee of the Board of Directors (the “Committee”). The aggregate number of our shares available for issuance under the 2007 Plan and 2013 Plan are 1,200,000 and 240,000, respectively. Under the 2007 Plan, no more than an aggregate of 400,000 shares are available for issue of stock-based awards other than stock options and stock appreciation rights. As of December 31, 2014, shares available for future grant under the 2007 Plan and 2013 Plan are 4,198 and 19,800, respectively. Prior the adoption of the 2007 Plan, we granted stock-based awards to purchase shares of our common stock to officers, key employees and non-employee directors under certain predecessor plans. No further awards can be granted under these predecessor plans.
	Stock Options
	In the years ended December 31, 2014, 2013, and 2012, we granted stock options to our officers, key employees and non-employee directors of 71,000, 190,500, and 222,100, respectively, with weighted-average grant date fair values of approximately $12.62, $10.95, and $4.95, respectively. Stock options have been granted with an exercise price equal to the fair market value of our stock on the date of grant and expire not more than ten years from the date of grant. The stock options vest over a period of four years after the date of grant. The option price and number of shares are subject to adjustment under certain dilutive circumstances. If an employee terminates employment, the non-vested portion of the stock options will not vest and all rights to the non-vested portion will terminate completely.
	Stock option activity for the year ended December 31, 2014 were as follows:
		Number		Weighted-			Weighted-Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value (in thousands)
		of Stock Options		Average
				Exercise
				Price Per Share
	Outstanding at January 1, 2014	702,001		$	18.46

	Outstanding at December 31, 2014	611,977		$	19.02		4.2	$	3,834
	Exerciseable at December 31, 2014	288,412		$	18.61		3.2	$	1,925
	Changes in nonvested stock options for the year ended December 31, 2014 were as follows:
		Number of Stock Options		Weighted-
				Average
				Grant
				Date Fair Value
	Nonvested at January 1, 2014	456,251		$	8.24
	Granted	71,000		12.62
	Vested	(168,198	)	7.87
	Forfeited	(35,488	)	8.14
	Nonvested at December 31, 2014	323,565		$	9.42
	The aggregate intrinsic value of stock options represents the amount by which the market price of our common stock exceeds the exercise price of the stock option. The aggregate intrinsic value of stock options exercised for the years ended December 31, 2014, 2013 and 2012 was approximately $1.0 million, $2.6 million, and zero, respectively. Cash received from stock option exercised for the years ended December 31, 2014, 2013 and 2012 was approximately $2.3 million, $8.8 million, and zero, respectively, with related tax benefits of $0.4 million, $1.0 million, and zero, respectively. The total stock options vested and expected to vest in the future are 611,977 shares with a weighted-average exercise price of approximately $19.02 and an aggregate intrinsic value of approximately $3.8 million. These stock options have a weighted-average remaining contractual term of approximately 4.2 years.
	The share-based compensation cost expensed for stock options for the years ended December 31, 2014 , 2013, and 2012 (before tax benefits) was approximately $1.5 million, $1.2 million, and $1.1 million, respectively, and is included in selling, general and administrative expenses on the consolidated income statements. At December 31, 2014, total unrecognized compensation cost (before tax benefits) related to stock options of approximately $2.4 million is expected to be recognized over a weighted-average period of approximately 2.4 years. The weighted-average grant date fair value of stock options granted during the years ended December 31, 2014, 2013, and 2012 was approximately $12.62, $10.95, and $4.95. The total fair value of stock options vested during the years ended December 31, 2014, 2013, and 2012 was approximately $1.3 million, $1.1 million, and $1.3 million, respectively.
	The assumptions used to compute the fair value of stock option grants under the Stock Incentive Plans for years ended December 31, 2014, 2013, and 2012 were as follows:
		Years Ended December 31,
		2014		2013		2012
	Risk-free interest rate	1.67	%	1.44	%	0.59	%
	Expected volatility	55.27	%	53.89	%	57.05	%
	Expected dividends	—		—		—
	Expected term (in months)	66		66		66
	We apply fair value accounting for stock-based compensation based on the grant date fair value estimated using a Black-Scholes-Merton (“Black-Scholes”) valuation model. We recognize compensation expense, net of an estimated forfeiture rate, on a straight-line basis over the requisite service period of the award. We have one award population with an option vesting term of four years. We estimate the forfeiture rate based on our historic experience, attempting to determine any discernible activity patterns. The expected life computation is based on historic exercise patterns and post-vesting termination behavior. The risk-free interest rate for periods within the contractual life of the award is based on the U.S. Treasury yield curve in effect at the time of grant. The expected volatility is derived from historical volatility of our common stock. We suspended payments of dividends after the first quarter of 2011.
	Restricted Stock Units
	We granted restricted stock units (“RSUs”) to certain officers, key employees and non-employee directors of approximately 86,300, 65,550, and 73,900 RSUs during the years ended December 31, 2014, 2013, and 2012, respectively, with weighted-average grant date fair values (equal to the fair market value of our stock on the date of grant) of approximately $24.74, $18.75, and $13.18 per share, respectively. RSUs represent a right to receive a share of stock at future vesting dates with no cash payment required from the holder. The RSUs have a three year vesting term of approximately 33%, 33% and 34% on the first, second and third anniversaries of the date of grant. If an employee terminates employment, their non-vested portion of the RSUs will not vest and all rights to the non-vested portion will terminate.
	Restricted stock unit activity for the year ended December 31, 2014 was as follows:
		Number of Restricted Stock Units		Weighted-
				Average
				Grant
				Date Fair Value
	Outstanding at January 1, 2014	93,358		$	17.79
	Granted	86,300		24.74
	Vested	(52,115	)	19.51
	Forfeited	(4,600	)	24.9
	Outstanding at December 31, 2014	122,943		$	21.67
	The share-based compensation cost expensed for RSUs for the years ended December 31, 2014 , 2013, and 2012 (before tax benefits) was approximately $1.3 million, $0.9 million, and $0.7 million respectively, and is included in selling, general and administrative expenses on the consolidated income statements. At December 31, 2014, total unrecognized compensation cost (before tax benefits) related to RSUs of approximately $1.6 million is expected to be recognized over a weighted average period of approximately 1.8 years. The total fair value of RSUs vested for the years ended December 31, 2014 , 2013, and 2012 was approximately $1.3 million, $1.1 million, and $0.6 million, respectively. The actual tax benefit realized for tax deductions from vested RSUs for the years ended December 31, 2014 , 2013, and 2012 was approximately $0.5 million, $0.4 million, and $0.3 million, respectively.
	Performance Stock Units
	We granted performance stock awards (“PSUs”) to certain key employees of approximately 67,500, 85,500, and 82,500 PSUs during the years ended December 31, 2014, 2013, and 2012, respectively, with weighted-average grant date fair values of approximately $24.90, $16.15, and $13.04 per share, respectively. PSU awards are subject to the attainment of performance goals established by the Committee, the periods during which performance is to be measured, and all other limitations and conditions applicable to the awarded shares. Performance goals are based on a pre-established objective formula or standard that specifies the manner of determining the number of performance stock awards that will be granted if performance goals are attained. If an employee terminates employment, their non-vested portion of the PSUs will not vest and all rights to the non-vested portion will terminate.
	Performance stock activity for the year ended December 31, 2014 is as follows:
		Number of Performance Stock Units		Weighted-
				Average
				Grant
				Date Fair Value
	Outstanding at January 1, 2014	152,972		$	15.44
	Granted	67,500		24.9
	Vested	(847	)	13.04
	Forfeited	(51,467	)	16.45
	Outstanding at December 31, 2014	168,158		$	18.94
	The share-based compensation cost expensed for PSUs for the years ended December 31, 2014 , 2013, and 2012 (before tax benefits) was approximately $1.0 million, $0.3 million and $0.6 million, respectively, and is included in selling, general and administrative expenses on the consolidated income statements. At December 31, 2014, total unrecognized compensation cost (before tax benefits) related to PSUs of approximately $1.5 million is expected to be recognized over a weighted-average period of approximately 1.3 years. The total fair value of PSUs vested during the years ended December 31, 2014, 2013, and 2012 was less than or equal to approximately $0.1 million, zero, and $0.1 million, respectively. No tax benefits were realized for tax deductions from vested PSUs for the years ended December 31, 2014 , 2013, and 2012.

Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plans	Employee Benefit Plans
	Supplemental Retirement Plans
	We have three unfunded supplemental retirement plans. The first plan was suspended in 1986, but continues to cover certain former executives. The second plan was suspended in 1997, but continues to cover certain current and retired directors. The third plan covers certain current and retired employees and further employee contributions to this plan were suspended on August 5, 2011. The liability for the third plan and interest thereon is included in accrued employee compensation and long-term liabilities and was approximately $0.3 million and $2.0 million, respectively, at December 31, 2014 and $0.4 million and $2.0 million, respectively, at December 31, 2013. The accumulated benefit obligations of the other two plans at December 31, 2014 and December 31, 2013 were approximately $0.9 million and $1.1 million, respectively, and are included in accrued liabilities.
	Defined Contribution 401(K) Plans
	We sponsor, for all our employees, two 401(k) defined contribution plans.The first plan covers all employees, other than employees at our Miltec subsidiary, and allows the employees to make annual voluntary contributions not to exceed the lesser of an amount equal to 25% of their compensation or limits established by the Internal Revenue Code. Under this plan, we generally provide a match equal to 50% of the employee’s contributions up to the first 6% of compensation, except for union employees who are not eligible to receive the match. The second plan covers only the employees at our Miltec subsidiary, and in 2013 the provisions of the Miltec plan were changed to be the same as our other plan. Prior to 2013, the Miltec plan allowed employees to make annual voluntary contributions not to exceed the lesser of an amount equal to 100% of their compensation or limits established by the Internal Revenue Code. Under this plan, Miltec generally (i) provided a match equal to 100% of the employee’s contributions up to the first 5% of compensation, (ii) contributions of 3% of an employee’s compensation annually, and (iii) contributions, at our discretion of 0% to 7% of an employee’s compensation annually. Our provision for matching and profit sharing contributions for the three years ended December 31, 2014, 2013, and 2012 was approximately $3.3 million, $3.1 million, and $3.8 million, respectively.
	Other Plans
	We have a defined benefit pension plan covering certain hourly employees of a subsidiary (the “Pension Plan”). Pension plan benefits are generally determined on the basis of the retiree’s age and length of service. Assets of this defined benefit pension plan are composed primarily of fixed income and equity securities. We also have a retirement plan covering certain current and retired employees (the “LaBarge Retirement Plan”).

	-1	Projected benefit obligation equals the accumulated benefit obligation for the plans.
	On December 31, 2014, our annual measurement date, the accumulated benefit obligation exceeded the fair value of the plans assets by approximately $13.6 million. Such excess is referred to as an unfunded accumulated benefit obligation. We recorded unrecognized loss included in accumulated other comprehensive loss, net of tax at December 31, 2014 and 2013 of approximately $6.6 million and $3.9 million, respectively, which decreased shareholders’ equity and was included in other long-term liabilities. This charge to shareholders’ equity represents a net loss not yet recognized as pension expense. This charge did not affect reported earnings, and would be decreased or be eliminated if either interest rates increase or market performance and plan returns improve or contributions cause the Pension Plan to return to fully funded status.
	Our Pension Plan asset allocations at December 31, 2014 and 2013, by asset category, were as follows:
			December 31,
			2014			2013
	Equity securities		76	%		78	%
	Cash and equivalents		4	%		4	%
	Debt securities		20	%		18	%
Total(1)		100	%		100	%
-1	Our overall investment strategy is to achieve an asset allocation within the following ranges to achieve an appropriate rate of return relative to risk.
Cash	0-25%
Fixed income securities	0-50%
Equities	50-95%
Pension Plan assets consist primarily of listed stocks and bonds and do not include any of the Company’s securities. The return on assets assumption reflects the average rate of return expected on funds invested or to be invested to provide for the benefits included in the projected benefit obligation. We select the return on asset assumption by considering our current and target asset allocation. We consider information from various external investment managers, forward-looking information regarding expected returns by asset class and our own judgment when determining the expected returns.

-1	Represents mutual funds and commingled accounts which invest primarily in equities, but may also hold fixed income securities, cash and other investments.
The valuation techniques used to determine fair value are as follows. Commingled funds with publicly quoted prices and active trading are classified as Level 1 investments. For commingled funds that are not publicly traded and have ongoing subscription and redemption activity, the fair value of the investment is the net asset value (“NAV”) per share, derived from the underlying securities’ quoted prices in active markets. These funds are classified as Level 2 investments.
The assumptions used to determine the benefit obligations and expense for our two plans are presented in the tables below. The expected long-term return on assets, noted below, represents an estimate of long-term returns on investment portfolios consisting of a mixture of fixed income and equity securities. The estimated cash flows from the plans for all future years are determined based on the plans’ population at the measurement date. We took the expected benefit payouts from the plans for each year into the future, and discounted them back to the present using the Wells Fargo yield curve rate for that duration.
The weighted-average assumptions used to determine the net periodic benefit costs under the two plans were as follows:

Disclosure of Guarantees and Indemnifications [Abstract]
Indemnifications	Indemnifications
	We have made guarantees and indemnities under which we may be required to make payments to a guaranteed or indemnified party, in relation to certain transactions, including revenue transactions in the ordinary course of business. In connection with certain facility leases, we have indemnified our lessors for certain claims arising from the facility or the lease. We indemnify our directors and officers to the maximum extent permitted under the laws of the State of Delaware.
	However, we have a directors and officers insurance policy that may reduce our exposure in certain circumstances and may enable us to recover a portion of future amounts that may be payable, if any. The duration of the guarantees and indemnities varies and, in many cases is indefinite but subject to statute of limitations. The majority of guarantees and indemnities do not provide any limitations of the maximum potential future payments we could be obligated to make. Historically, payments related to these guarantees and indemnities have been immaterial. We estimate the fair value of our indemnification obligations as insignificant based on this history and insurance coverage and have, therefore, not recorded any liability for these guarantees and indemnities in the accompanying consolidated balance sheets.

	We have federal tax credit carryforwards of approximately $2.7 million, which begin to expire in 2033. In addition, we have recorded benefits for those carryforwards expected to be utilized on tax returns filed in the future. Further, there was an approximate $1.0 million of federal tax credit carryforwards unrecognized as a result of the application of ASC Subtopic 740-10.
	We have state tax credit carryforwards of approximately $8.3 million, which begin to expire in 2017, and state net operating losses of approximately $26.6 million, which begin to expire in 2015. We have recorded a full valuation allowance on these carryforwards as they are not expected to be realized. Further, there was an approximate $1.0 million of state tax credit carryforwards unrecognized as a result of the application of ASC Subtopic 740-10.
	We have established a valuation allowance for items that are not expected to provide future tax benefits. We believe it is more likely than not that we will generate sufficient taxable income to realize the benefit of the remaining deferred tax assets.
	The principal reasons for the variation between the expected and effective tax rates were as follows:
		Years Ended December 31,
		2014		2013	2012
				As Restated	As Restated
	Statutory federal income tax rate	35.00%		35.00%	35.00%

Other	—		-1.1	0.6
Effective income tax rate (benefit)	24.30%		-21.20%	26.90%
The deduction for qualified domestic production activities is treated as a “special deduction” which has no effect on deferred tax assets and liabilities. Instead, the impact of this deduction is reported in our rate reconciliation.
We recorded an income tax expense of approximately $6.4 million (an effective tax rate of 24.3%) in 2014, compared to an income tax benefit of approximately $2.0 million (an effective tax benefit rate of 21.2%) in 2013. In December 2014, the federal research and development tax credit was retroactively extended from the beginning of 2014. We recognized total federal research and development tax credits of approximately $2.4 million in 2014.
The effective tax rate for 2013 included approximately $2.0 million of 2012 federal research and development tax credit benefits recognized in the first quarter of 2013 as a result of the American Taxpayer Relief Act (the “Act”) of 2012 passed in January 2013. The Act includes an extension of the federal research and development tax credit for the amounts paid or incurred after December 31, 2011 and before January 1, 2014. We recognized total federal research and development tax credit benefits of approximately $4.5 million in 2013.
We record interest and penalty charge, if any, related to uncertain tax positions as a component of tax expense. During the three years ended December 31, 2014, 2013 and 2012, we recognized approximately zero, zero and $(0.1) million, respectively, in interest benefit related to uncertain tax positions. We had approximately $0.1 million for payment of interest and penalties accrued for all three years ended December 31, 2014, 2013, and 2012.
Our total amount of unrecognized tax benefits was approximately $2.8 million, $2.3 million, and $1.4 million at December 31, 2014, 2013, and 2012 respectively. Approximately $1.9 million, if recognized, would affect the annual income tax rate. We do not reasonably expect significant increases or decreases to our unrecognized tax benefits in the next twelve months.
A reconciliation of the beginning and ending amount of unrecognized tax benefits was as follows:

Contingencies	Contingencies
	On October 8, 2014, the United States District Court for the District of Kansas (the “District Court”) granted summary judgment in favor of The Boeing Company (“Boeing”) and Ducommun and dismissed the lawsuit entitled United States of America ex rel Taylor Smith, Jeannine Prewitt and James Ailes v. The Boeing Company and Ducommun Inc.. The lawsuit was a qui tam action brought by three former Boeing employees (“Relators”) against Boeing and Ducommun on behalf of the United States of America for violations of the United States False Claims Act. Relators have appealed the dismissal to the Tenth Circuit Court of Appeals. The lawsuit alleged that Ducommun sold unapproved parts to Boeing which were installed by Boeing in aircraft ultimately sold to the United States Government and that Boeing and Ducommun submitted or caused to be submitted false claims for payment relating to 21 aircraft sold by Boeing to the United States Government. The lawsuit sought damages in an amount equal to three times the amount of damages the United States Government sustained because of the defendants’ actions, plus a civil penalty of $10 thousand for each false claim made on or before September 28, 1999, and $11 thousand for each false claim made on or after September 28, 1999, together with attorneys’ fees and costs. The Relators claimed that the United States Government sustained damages of $1.6 billion (the contract purchase price of 21 aircraft) or, alternatively, $851 million (the alleged diminished value and increased maintenance cost of the 21 aircraft). After investigating the allegations, the United States Government declined to intervene in the lawsuit.
	DAS has been directed by California environmental agencies to investigate and take corrective action for groundwater contamination at its facilities located in El Mirage and Monrovia, California. Based on currently available information, Ducommun has established a reserve for its estimated liability for such investigation and corrective action of approximately $1.5 million at December 31, 2014, which is reflected in other long-term liabilities on its consolidated balance sheet.
	DAS also faces liability as a potentially responsible party for hazardous waste disposed at landfills located in Casmalia and West Covina, California. DAS and other companies and government entities have entered into consent decrees with respect to these landfills with the United States Environmental Protection Agency and/or California environmental agencies under which certain investigation, remediation and maintenance activities are being performed. Based on currently available information, Ducommun preliminarily estimates that the range of its future liabilities in connection with the landfill located in West Covina, California is between approximately $0.4 million and $3.1 million. Ducommun has established a reserve for its estimated liability, in connection with the West Covina landfill of approximately $0.4 million at December 31, 2014, which is reflected in other long-term liabilities on its consolidated balance sheet. Ducommun’s ultimate liability in connection with these matters will depend upon a number of factors, including changes in existing laws and regulations, the design and cost of construction, operation and maintenance activities, and the allocation of liability among potentially responsible parties.
	In the normal course of business, Ducommun and its subsidiaries are defendants in certain other litigation, claims and inquiries, including matters relating to environmental laws. In addition, Ducommun makes various commitments and incurs contingent liabilities. While it is not feasible to predict the outcome of these matters, Ducommun does not presently expect that any sum it may be required to pay in connection with these matters would have a material adverse effect on its consolidated financial position, results of operations or cash flows.

	We provide proprietary products and services to the Department of Defense and various United States Government agencies, and most of the aerospace and aircraft manufacturers who receive contracts directly from the U.S. Government as an original equipment manufacturer (“prime manufacturers”). In addition, we also service technology-driven markets in the industrial, natural resources and medical and other end-use markets. As a result, we have significant net revenues from certain customers. Accounts receivable were diversified over a number of different commercial, military and space programs and were made by both operating segments. Net revenues from our top ten customers, including the Boeing Company (“Boeing”) and Raytheon Company (“Raytheon”), represented the following percentages of total net sales:
		Years Ended December 31,

	In 2014, 2013 and 2012, net revenues from foreign customers on the location of the customer, were approximately $66.7 million, $66.0 million and $52.1 million, respectively. No net revenues from a foreign country were greater than approximately 2% of total net revenues in 2014, 2013, and 2012. We have manufacturing facilities in Thailand and Mexico. Our net revenues, profitability and identifiable long-lived assets attributable to foreign revenues activity were not material compared to our net revenues, profitability and identifiable long-lived assets attributable to our domestic operations during 2014, 2013, and 2012. We are not subject to any significant foreign currency risks as all our sales are made in United States dollars.

Accounting Policies [Abstract]
Description of Business	Description of Business
	We are a leading global provider of engineering and manufacturing services for high-performance products and high-cost-of failure applications used primarily in the aerospace, defense industrial, natural resources, medical and other industries. Our subsidiaries are organized into two strategic businesses; Ducommun LaBarge Technologies (“DLT”) and Ducommun AeroStructures (“DAS”), each of which is a reportable operating segment. DLT designs, engineers and manufactures high-reliability products used in worldwide technology-driven markets including aerospace and defense, natural resources, industrial and medical and other end-use markets. DLT’s product offerings range from prototype development to complex assemblies. DAS designs, engineers and manufactures large, complex contoured aerospace structural components and assemblies and supplies composite and metal bonded structures and assemblies. DAS’s products are used on commercial aircraft, military fixed-wing aircraft and military and commercial rotary-wing aircraft. All reportable operating segments follow the same accounting principles.
Basis of Presentation	Basis of Presentation
	The consolidated financial statements include the accounts of Ducommun Incorporated and its subsidiaries (“Ducommun,” the “Company,” “we,” “us” or “our”), after eliminating intercompany balances and transactions.
	Our fiscal quarters end on the Saturday closest to the end of March, June and September for the first three fiscal quarters of each year, and ends on December 31 for our fourth fiscal quarter.
	In the opinion of management, all adjustments, consisting of recurring accruals, have been made that are necessary to fairly state our consolidated financial position, results of operations, comprehensive income (loss) and cash flows in accordance with accounting principles generally accepted in the United States of America (“GAAP”).
Use of Estimates	Use of Estimates
	Certain amounts and disclosures included in the consolidated financial statements required management to make estimates and judgments that affect the amounts of assets, liabilities (including forward loss reserves), revenues and expenses, and related disclosures of contingent assets and liabilities. These estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from these estimates.
Reclassifications	Reclassifications
	Certain prior period amounts have been reclassified to conform to current year’s presentation.
Cash Equivalents	Cash Equivalents
	Our cash accounts are not reduced for checks written until the checks are presented for payment and paid by our bank. Cash equivalents consist of highly liquid instruments purchased with original maturities of three months or less. These assets are valued at cost, which approximates fair value, which we classify as Level 1. See Fair Value below.
Revenue Recognition	Revenue Recognition
	Except as described below, we recognize revenue, including revenue from products sold under long-term contracts, when persuasive evidence of an arrangement exists, the price is fixed or determinable, collection is reasonably assured and delivery of products has occurred or services have been rendered.
	We have a significant number of contracts for which net revenues are accounted for under the percentage-of-completion method using the units of delivery as the measure of completion. The percentage-of-completion method requires the use of assumptions and estimates related to the contract value, the total cost at completion, and measurement of progress toward completion. These contracts are primarily fixed-price contracts that vary widely in terms of size, length of performance period and expected gross profit margins.
	We also recognize revenue on the sale of services (including prototype products) based on the type of contract: time and materials, cost-plus reimbursement and firm-fixed price. Revenue is recognized (i) on time and materials contracts as time is spent at hourly rates, which are negotiated with customers, plus the cost of any allowable materials and out-of-pocket expenses, (ii) on cost-plus reimbursement contracts based on direct and indirect costs incurred plus a negotiated profit calculated as a percentage of cost, a fixed amount or a performance-based award fee, and (iii) on fixed-price contracts on the percentage-of-completion method measured by the percentage of costs incurred to estimated total costs.
Provision for Estimated Losses on Contracts	Provision for Estimated Losses on Contracts
	We record provisions for the total anticipated losses on contracts considering total estimated costs to complete the contract compared to total anticipated revenues in the period in which such losses are identified. The provisions for estimated losses on contracts require management to make certain estimates and assumptions, including those with respect to the future revenue under a contract and the future cost to complete the contract. Management's estimate of the future cost to complete a contract may include assumptions as to improvements in manufacturing efficiency, reductions in operating and material costs, and our ability to resolve claims and assertions with our customers. If any of these or other assumptions and estimates do not materialize in the future, we maybe required to record additional provisions for estimated losses on contracts.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts
	We maintain an allowance for doubtful accounts for estimated losses from the inability of customers to make required payments. The allowance for doubtful accounts is evaluated periodically based on the aging of accounts receivable, the financial condition of customers and their payment history, historical write-off experience and other assumptions, such as current assessment of economic conditions.
Inventory Valuation	Inventories
	Inventories are stated at the lower of cost or market, cost being determined on a first-in, first-out basis. Market value for raw materials is based on replacement costs, and is based on net realizable value for other inventory classifications. Inventoried costs include raw materials, outside processing, direct labor and allocated overhead, adjusted for any abnormal amounts of idle facility expense, freight, handling costs, and wasted materials (spoilage) incurred. Costs under long-term contracts are accumulated into, and removed from, inventory on the same basis as other contracts. We assess the inventory carrying value and reduce it, if necessary, to its net realizable value based on customer orders on hand, and internal demand forecasts using management’s best estimates given information currently available. We maintain an allowance for potentially excess and obsolete inventories and inventories that are carried at costs that are higher than their estimated net realizable values.
Production Cost of Contracts	Production Cost of Contracts
	Production cost of contracts includes non-recurring production costs, such as design and engineering costs, and tooling and other special-purpose machinery necessary to build parts as specified in a contract. Production costs of contracts are recorded to cost of goods sold using the units of delivery method. We review long-lived assets within production costs of contracts for impairment on an annual basis (in the fourth quarter for us) or when events or changes in circumstances indicate that the carrying value of our long-lived assets may not be recoverable. An impairment charge is recognized when the carrying value of an asset exceeds the projected undiscounted future cash flows expected from its use and disposal. In the fourth quarter of 2013, we recorded an impairment charge in the DAS segment on production costs of contracts of $7.0 million, consisting of $5.7 million for the Embraer Legacy 450/500 aircraft contracts, and $1.3 million for the Boeing 777 wing tip contract. The impairment charge reflects a determination that the production cost of contracts for the Boeing 777 wing tip contract and the Embraer Legacy 450/500 contracts are not recoverable since these contracts are estimated to be unprofitable during their remaining terms. The impairment charge represents the entire remaining balance of production cost of contracts for these contracts. The $7.0 million charge was recorded as part of cost of goods sold in the Company’s results of operations and a reduction in production cost of contracts on the Company’s balance sheet. As of December 31, 2014 and 2013, production costs of contracts were approximately $11.7 million and $11.6 million, respectively.
Property and Equipment and Depreciation	Property and Equipment and Depreciation
	Property and equipment, including assets recorded under capital leases, are recorded at cost. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the related assets, or the lease term if shorter for leasehold improvements. Repairs and maintenance are charged to expense as incurred. We evaluate long-lived assets for recoverability considering undiscounted cash flows, when significant changes in conditions occur, and recognize impairment losses if any, based upon the fair value of the assets.
Fair Value	Fair Value
	Assets and liabilities that are measured, recorded or disclosed at fair value on a recurring basis are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1, the highest level, refers to the values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant observable inputs. Level 3, the lowest level, includes fair values estimated using significant unobservable inputs.
Goodwill and Indefinite-Lived Intangible Asset	Goodwill and Indefinite-Lived Intangible Asset
	Goodwill is tested for impairment utilizing a two-step method. In the first step, we determine the fair value of the reporting unit using expected future discounted cash flows and market valuation approaches considering comparable Company revenue and Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”) multiples. If the carrying value of the reporting unit exceeds its fair value, we then perform the second step of the impairment test to measure the amount of the impairment loss, if any. The second step requires fair valuation of all the reporting unit’s assets and liabilities in a manner similar to a purchase price allocation, with any residual fair value being allocated to goodwill. This residual fair value of goodwill is then compared to its carrying value to determine impairment. An impairment charge will be recognized only when the estimated fair value of a reporting unit, including goodwill, is less than its carrying value.
	We review our indefinite-lived intangible asset for impairment on an annual basis or when events or changes in circumstances indicate that the carrying value of our intangible asset may not be recoverable. We may first assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test. Impairment indicators include, but are not limited to, cost factors, financial performance, adverse legal or regulatory developments, industry and market conditions and general economic conditions. If the carrying amount of the indefinite-lived intangible asset exceeds its fair value, we would recognize an impairment loss in the amount of such excess.
Income Taxes	Income Taxes
	Deferred tax assets and liabilities are recognized, using enacted tax rates, for the expected future tax consequences of temporary differences between the book and tax bases of recorded assets and liabilities, operating losses and tax credit carryforwards. Deferred tax assets are evaluated quarterly and are reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized.
	Tax positions taken or expected to be taken in a tax return are recognized when it is more-likely-than-not to be sustained upon examination by taxing authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement.
Litigation and Commitments	Litigation and Commitments
	In the normal course of business, we are defendants in certain litigation, claims and inquiries, including matters relating to environmental laws. In addition, we make various commitments and incur contingent liabilities. Management’s estimates regarding contingent liabilities could differ from actual results.
Environmental Liabilities	Environmental Liabilities
	Environmental liabilities are recorded when environmental assessments and/or remedial efforts are probable and costs can be reasonably estimated. Generally, the timing of these accruals coincides with the completion of a feasibility study or our commitment to a formal plan of action. Further, we review and update our environmental accruals as circumstances change and/or additional information is obtained that reasonably could be expected to have a meaningful effect on the outcome of a matter or the estimated cost thereof.
Accounting for Stock-Based Compensation	Accounting for Stock-Based Compensation
	We measure and recognize compensation expense for share-based payment transactions to our employees and non-employees at their estimated fair value. The expense is measured at the grant date, based on the calculated fair value of the share-based award, and is recognized over the requisite service period (generally the vesting period of the equity award). The fair value stock options are determined using the Black-Scholes valuation model, which requires assumptions and judgments regarding stock price volatility, risk-free interest rates, expected options terms, and options that are expected to be forfeited. The fair value of unvested stock awards is determined based on the closing price of the underlying common stock on the date of grant. Management’s estimates could differ from actual results.
Other Intangible Assets	Other Intangible Assets
	We amortize purchased other intangible assets with finite lives over the estimated economic lives of the assets, ranging from three to eighteen years generally using the straight-line method. The value of other intangibles acquired through business combinations has been estimated using present value techniques which involve estimates of future cash flows. We evaluate other intangible assets for recoverability considering undiscounted cash flows, when significant changes in conditions occur, and recognizes impairment losses, if any, based upon the estimated fair value of the assets.
Earnings per Share	Earnings Per Share
	Basic earnings per share are computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding in each period. Diluted earnings per share are computed by dividing income available to common shareholders plus income associated with dilutive securities by the weighted-average number of common shares outstanding, plus any potential dilutive shares that could be issued if exercised or converted into common stock in each period.
Accumulated Other Comprehensive Loss	Accumulated Other Comprehensive Loss
	Accumulated other comprehensive loss, as reflected in the consolidated balance sheets under the equity section, was composed of cumulative pension and retirement liability adjustments, net of tax.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	New Accounting Guidance Adopted in 2014
	In July 2013, the FASB issued Accounting Standards Update 2013-11, “Income Taxes (Topic 740)” (“ASU 2013-11”), which required the netting of unrecognized tax benefits against a deferred tax asset for a loss or other carryforward that would apply in settlement of the uncertain tax positions. This guidance was effective for fiscal years beginning after December 15, 2013, which is our fiscal year 2014, with early adoption permitted. The adoption of this standard at the beginning of our fiscal year 2014 reduced deferred tax assets by approximately $0.7 million.
	In February 2013, the FASB issued ASU 2013-04, “Liabilities (Topic 405)” (“ASU 2013-04”), which provided guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date, except for obligations addressed within existing guidance in GAAP. The new guidance was effective for us beginning January 1, 2014. Early adoption was permitted. The adoption of this standard at the beginning of our fiscal year 2014 did not have a material impact on our consolidated financial statements.
	Recently Issued Accounting Standards
	In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“ASU 2014-15”), which defines management’s responsibility to evaluate whether there is substantial doubt about a company’s ability to continue as a going concern. ASU 2014-15 also provide principles and definitions that are intended to reduce diversity in the timing and content of disclosures in the financial statement footnotes. The new guidance is effective for annual periods ending after December 15, 2016, which will be our year ending December 31, 2016, and interim periods beginning after December 15, 2016, which will be our interim period beginning January 1, 2017. Early adoption is permitted. We are evaluating the impact of this standard but currently do not anticipate it will have a significant impact on our consolidated financial statements.
	In June 2014, the FASB issued ASU 2014-12, “Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide that a Performance Target Could be Achieved after the Requisite Service Period” (“ASU 2014-12”), which requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. Thus, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The new guidance is effective for us beginning January 1, 2016. Early adoption is permitted. We currently do not anticipate the adoption of this standard will have a material impact on our consolidated financial statements.
	In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. It requires entities to exercise judgment when considering the terms of the contract(s) which include (i) identifying the contract(s) with the customer, (ii) identifying the separate performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the separate performance obligations, and (v) recognizing revenue when each performance obligation is satisfied. Thus, it depicts the transfer of promised goods or services to customers in an amount that reflects the consideration an entity expects to receive in exchange for those goods or services. Companies have the option of applying the provisions of ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying this guidance recognized at the date of initial application. Early adoption is not permitted. The new guidance is effective for us beginning January 1, 2017. We are currently evaluating the method and impact that adopting this new accounting standard will have on our consolidated financial statements.
