Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	BASIS OF PRESENTATION AND ORGANIZATION The accompanying unaudited condensed consolidated financial statements of Triumph Group, Inc. (the "Company") have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position and cash flows. The results of operations for the three and nine months ended December 31, 2016 are not necessarily indicative of results that may be expected for the year ending March 31, 2017 . The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the fiscal 2016 audited condensed consolidated financial statements and notes thereto included in the Company's Form 10-K for the year ended March 31, 2016 filed with the Securities and Exchange Commission (the "SEC") on May 27, 2016. The Company designs, engineers, manufactures, repairs and overhauls a broad portfolio of aerostructures, aircraft components, accessories, subassemblies and systems. The Company serves a broad, worldwide spectrum of the aviation industry, including original equipment manufacturers of commercial, regional, business and military aircraft and aircraft components, as well as commercial and regional airlines and air cargo carriers. Effective April 1, 2016, the Company realigned into four reportable segments: Integrated Systems, Aerospace Structures, Precision Components and Product Support segments (see Note 12).

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Revenue Recognition Revenues are generally recognized in accordance with the contract terms when products are shipped, delivery has occurred or services have been rendered, pricing is fixed and determinable, and collection is reasonably assured. A significant portion of the Company’s contracts are within the scope of the Revenue Recognition - Construction-Type and Production-Type Contracts topic of the Accounting Standards Codification ("ASC") 605-35 and revenue and costs on contracts are recognized using the percentage-of-completion method of accounting. Accounting for the revenue and profit on a contract requires estimates of (1) the contract value or total contract revenue, (2) the total costs at completion, which is equal to the sum of the actual incurred costs to date on the contract and the estimated costs to complete the contract’s scope of work, and (3) the measurement of progress toward completion. Depending on the contract, the Company measures progress toward completion using either the cost-to-cost method or the units-of-delivery method of accounting, with the great majority measured under the units-of-delivery method of accounting. • Under the cost-to-cost method of accounting, progress toward completion is measured as the ratio of total costs incurred to estimated total costs at completion. Costs are recognized as incurred. Profit is determined based on estimated profit margin on the contract multiplied by the progress toward completion. Revenue represents the sum of costs and profit on the contract for the period. • Under the units-of-delivery method of accounting, revenue on a contract is recorded as the units are delivered and accepted during the period at an amount equal to the contractual selling price of those units. The costs recorded on a contract under the units-of-delivery method of accounting are equal to the total costs at completion divided by the total units to be delivered. As contracts can span multiple years, the Company often segments the contracts into production lots for the purposes of accumulating and allocating cost. Profit is recognized as the difference between revenue for the units delivered and the estimated costs for the units delivered. Adjustments to original estimates for a contract’s revenues, estimated costs at completion and estimated total profit are often required as work progresses under a contract, as experience is gained and as more information is obtained, even though the scope of work required under the contract may not change, or if contract modifications occur. These estimates are also sensitive to the assumed rate of production. Generally, the longer it takes to complete the contract quantity, the more relative overhead that contract will absorb. The impact of revisions in cost estimates is recognized on a cumulative catch-up basis in the period in which the revisions are made. Provisions for anticipated losses on contracts are recorded in the period in which they become evident (‘‘forward losses’’) and are first offset against costs that are included in inventory, with any remaining amount reflected in accrued contract liabilities in accordance with the Revenue Recognition - Construction-Type and Production-Type Contracts topic. Revisions in contract estimates, if significant, can materially affect results of operations and cash flows, as well as valuation of inventory. Furthermore, certain contracts are combined or segmented for revenue recognition in accordance with the Revenue Recognition - Construction-Type and Production-Type Contracts topic. During the quarter ended September 30, 2016, the Company discovered an immaterial error in its percentage-of-completion accounting for one of its contracts, which understated cost of sales and overstated net income for the three months ended June 30, 2016, in the amount of $11,800 and $8,142 , respectively and overstated retained earnings as of March 31, 2016, in the amount of $12,700 . The Company assessed the materiality of this error on previously issued financial statements in accordance with the ASC 250, Presentation of Financial Statements , and Securities and Exchange Commission (SEC) Staff Accounting Bulletin No. 99, Materiality. The Company concluded, based on a review of the quantitative and qualitative factors of the materiality of the amount, that the error was not material to any previously issued financial statements and the correction of the error in the three months ended September 30, 2016 was not material to that period’s financial statements. Accordingly, in order to correct this immaterial error, the Company has recorded a charge to "Cost of sales" in the amount of $24,500 , which is presented on the accompanying Condensed Consolidated Statements of Income during the nine months ended December 31, 2016 . For the three months ended December 31, 2016 , cumulative catch-up adjustments from changes in estimates, inclusive of changes in forward loss estimates, increased operating income, net income and earnings per share by approximately $2,131 , $1,762 and $0.04 , net of tax, respectively. The cumulative catch-up adjustments to operating income for the three months ended December 31, 2016 , included gross favorable adjustments of approximately $9,663 and gross unfavorable adjustments of approximately $(7,532) . For the three months ended December 31, 2015 , cumulative catch-up adjustments from changes in estimates decreased operating income, net income and earnings per share by approximately $(2,846) , $(1,776) and $(0.04) , net of tax, respectively. For the nine months ended December 31, 2016 , cumulative catch-up adjustments from changes in estimates, inclusive of changes in forward loss estimates and the correction of the error noted above, decreased operating income, net income and earnings per share by approximately $(6,290) , $(4,522) and $(0.09) , net of tax, respectively. The cumulative catch-up adjustments to operating income for the nine months ended December 31, 2016 , included gross favorable adjustments of approximately $50,180 and gross unfavorable adjustments of approximately $(56,470) , which includes a reduction to the previously recognized forward losses on the 747-8 program of $41,300 . For the nine months ended December 31, 2015 , cumulative catch-up adjustments from changes in estimates decreased operating income, net income and earnings per share by approximately $(13,796) , $(11,690) and $(0.24) , net of tax, respectively. Amounts representing contract change orders or claims are only included in revenue when such change orders or claims have been settled with the customer and to the extent that units have been delivered. Additionally, some contracts may contain provisions for revenue sharing, price re-determination, requests for equitable adjustments, change orders or cost and/or performance incentives. Such amounts or incentives are included in contract value when the amounts can be reliably estimated and their realization is reasonably assured. Although fixed-price contracts, which extend several years into the future, generally permit the Company to keep unexpected profits if costs are less than projected, the Company also bears the risk that increased or unexpected costs may reduce profit or cause the Company to sustain losses on the contract. In a fixed-price contract, the Company must fully absorb cost overruns, notwithstanding the difficulty of estimating all of the costs the Company will incur in performing these contracts and in projecting the ultimate level of revenue that may otherwise be achieved. As disclosed during fiscal 2016, the Company recognized a provision for forward losses associated with our long-term contract on the 747-8 and Bombardier programs. There is still risk similar to what the Company has experienced on the 747-8 and Bombardier programs. Particularly, the Company's ability to manage risks related to supplier performance, execution of cost reduction strategies, hiring and retaining skilled production and management personnel, quality and manufacturing execution, program schedule delays, potential need to negotiate facility lease extensions or alternatively relocate work and many other risks, will determine the ultimate performance of these programs. Included in net sales of Integrated Systems, Aerospace Structures and Precision Components is the non-cash amortization of acquired contract liabilities that were recognized as fair value adjustments through purchase accounting from various acquisitions. For the three months ended December 31, 2016 and 2015 , the Company recognized $29,206 and $34,425 , respectively, into net sales on the accompanying Condensed Consolidated Statements of Income. For the nine months ended December 31, 2016 and 2015 , the Company recognized $89,031 and $99,928 , respectively, into net sales on the accompanying Condensed Consolidated Statements of Income. The Product Support provides repair and overhaul services, of which a small portion of services are provided under long-term power-by-the-hour contracts. The Company applies the proportional performance method of accounting to recognize revenue under these contracts. Revenue is recognized over the contract period as units are delivered based on the relative value in proportion to the total estimated contract consideration. In estimating the total contract consideration, management evaluates the projected utilization of its customers’ fleet over the term of the contract, in connection with the related estimated repair and overhaul servicing requirements to the fleet based on such utilization. Changes in utilization of the fleet by customers, among other factors, may have an impact on these estimates and require adjustments to estimates of revenue to be realized. Concentration of Credit Risk The Company’s trade accounts receivable are exposed to credit risk. However, the risk is limited due to the diversity of the customer base and the customer base’s wide geographical area. Trade accounts receivable from Boeing (representing commercial, military and space) represented approximately 11% and 18% of total trade accounts receivable as of December 31, 2016 and March 31, 2016 , respectively. The Company had no other concentrations of credit risk of more than 10% . Sales to Boeing for the nine months ended December 31, 2016 , were $928,020 , or 36% of net sales, of which $157,772 , $427,960 , $317,426 and $24,862 were from the Integrated Systems, Aerospace Structures, Precision Components and Product Support, respectively. Sales to Boeing for the nine months ended December 31, 2015 , were $1,068,313 , or 38% of net sales, of which $146,882 , $648,380 , $247,579 and $25,472 were from the Integrated Systems, Aerospace Structures, Precision Components and Product Support, respectively. Sales to Gulfstream Aerospace Corporation for the nine months ended December 31, 2016 , were $321,671 , or 12% of net sales, of which $1,418 , $311,207 , $8,855 and $191 were from the Integrated Systems, Aerospace Structures, Precision Components and Product Support, respectively. Sales to Gulfstream for the nine months ended December 31, 2015 , were $366,710 , or 13% of net sales, of which $2,665 , $358,768 , $5,264 and $13 were from the Integrated Systems, Aerospace Structures, Precision Components and Product Support, respectively. No other single customer accounted for more than 10% of the Company’s net sales. However, the loss of any significant customer, including Boeing and Gulfstream, could have a material adverse effect on the Company and its operating subsidiaries. Stock-Based Compensation The Company recognizes compensation expense for share-based awards based on the fair value of those awards at the date of grant. Stock-based compensation expense for the three months ended December 31, 2016 and 2015 , was $2,163 and $737 , respectively. Stock-based compensation expense for the nine months ended December 31, 2016 and 2015 , was $6,140 and $1,908 , respectively. The Company has classified share-based compensation within selling, general and administrative expenses to correspond with the same line item as the majority of the cash compensation paid to employees. Upon the exercise of stock options or vesting of restricted stock, the Company first transfers treasury stock, then issues new shares. Intangible Assets The components of intangible assets, net, are as follows: December 31, 2016 Weighted- Average Life Gross Carrying Amount Accumulated Amortization Net Customer relationships 16.6 $ 662,757 $ (230,449 ) $ 432,308 Product rights, technology and licenses 11.7 54,319 (38,925 ) 15,394 Non-compete agreements and other 16.3 2,756 (739 ) 2,017 Tradenames 20.0 163,000 (7,471 ) 155,529 Total intangibles, net $ 882,832 $ (277,584 ) $ 605,248 March 31, 2016 Weighted- Average Life Gross Carrying Amount Accumulated Amortization Net Customer relationships 16.4 $ 683,309 $ (215,546 ) $ 467,763 Product rights, technology and licenses 11.7 55,739 (37,695 ) 18,044 Non-compete agreements and other 16.1 2,881 (718 ) 2,163 Tradenames 20.0 163,000 (1,358 ) 161,642 Total intangibles, net $ 904,929 $ (255,317 ) $ 649,612 During the fiscal year ended March 31, 2016, the Company performed interim and annual assessments of the fair value of indefinite-lived intangible assets. The Company concluded the fair value of the Vought and Embee tradenames did not exceed their carrying value. Accordingly, the Company recorded non-cash impairment charges during the fiscal year ended March 31, 2016. Additionally, the Company determined that the tradenames will be amortized over their estimated remaining useful life of 20 years. Amortization expense for the three months ended December 31, 2016 and 2015 , was $13,348 and $12,409 , respectively. Amortization expense for the nine months ended December 31, 2016 and 2015 , was $40,565 and $42,819 , respectively. Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When determining fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing an asset or liability. The fair value hierarchy has three levels of inputs that may be used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability; and Level 3—Unobservable inputs for the asset or liability. The Company has applied fair value measurements to its interest rate swap (see Note 4 and Note 6). Warranty Reserves A reserve has been established to provide for the estimated future cost of warranties on our delivered products. The Company periodically reviews the reserves and adjustments are made accordingly. A provision for warranty on products delivered is made on the basis of historical experience and identified warranty issues. Warranties cover such factors as non-conformance to specifications and defects in material and workmanship. The majority of the Company's agreements include a three -year warranty, although certain programs have warranties up to 20 years. The warranty reserves as of December 31, 2016 and March 31, 2016 , were $108,287 and $112,937 , respectively. Supplemental Cash Flow Information The Company paid $5,936 and $2,636 for income taxes, net of refunds, for the nine months ended December 31, 2016 and 2015 , respectively. The Company made interest payments of $61,251 and $54,752 for the nine months ended December 31, 2016 and 2015 , respectively. During the nine months ended December 31, 2016 and 2015 , the Company financed $11,504 and $13 , respectively, of property and equipment additions through capital leases. As of December 31, 2016 , the Company remains able to purchase an additional 2,277,789 shares under the existing stock repurchase program. However, there are certain restrictions placed on the repurchase program by the Company's lenders that prevent any repurchases at this time.

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS Acquisition of Fairchild Controls Corporation Effective October 21, 2015, the Company acquired all of the outstanding shares of Fairchild Controls Corporation ("Fairchild"). Fairchild is a leading provider of proprietary thermal management systems, auxiliary power generation systems, and related aftermarket spares and repairs. The acquired business operates as Triumph Thermal Systems-Maryland, Inc. and its results are included in Integrated Systems from the date of acquisition. The purchase price for Fairchild was $57,130 , including a working capital adjustment paid in January 2016. Goodwill in the amount of $14,695 was recognized for this acquisition and is calculated as the excess of consideration transferred over the net assets recognized and represents future economic benefits arising from other assets acquired that could not be individually identified and separately recognized such as assembled workforce. The goodwill is not deductible for tax purposes. The Company has also identified an intangible asset related to customer relationships valued at $18,000 with a weighted-average life of 12.0 years. The following condensed balance sheet represents the amounts assigned to each major asset and liability caption in the aggregate from the acquisition of Fairchild, in accordance with ASC 805, Business Combinations : October 21, 2015 Cash $ 9,075 Accounts receivable 8,841 Inventory 15,069 Prepaid expenses 263 Property and equipment 6,632 Goodwill 14,695 Intangible assets 18,000 Deferred taxes 5,889 Total assets $ 78,464 Accounts payable $ 1,284 Accrued expenses 12,183 Other noncurrent liabilities 7,867 Total liabilities $ 21,334 The Company finalized its estimates after it was able to determine that it had obtained all necessary information that existed as of the acquisition date related to these matters.

INVENTORIES	INVENTORIES Inventories are stated at the lower of cost (average-cost or specific-identification methods) or market. The components of inventories are as follows: December 31, 2016 March 31, 2016 Raw materials $ 102,002 $ 81,989 Work-in-process, including manufactured and purchased components 1,289,607 1,100,660 Finished goods 137,157 124,744 Rotable assets 54,622 51,952 Less: unliquidated progress payments (109,334 ) (123,155 ) Total inventories $ 1,474,054 $ 1,236,190 Work-in-process inventory includes capitalized pre-production costs on newer development programs. Capitalized pre-production costs include nonrecurring engineering, planning and design, including applicable overhead, incurred before production is manufactured on a regular basis. Significant customer-directed work changes can also cause pre-production costs to be incurred. These costs are typically recovered over a contractually determined number of ship set deliveries. The balance of development program inventory, comprised principally of capitalized pre-production costs, excluding progress payments related to the Company's contracts with Bombardier for the Global 7000/8000 program ("Bombardier") and Embraer for the second generation E-Jet program ("Embraer") are as follows: December 31, 2016 Inventory Capitalized Pre-Production Forward Loss Provision Total Inventory, net Bombardier $ 53,702 $ 548,710 $ (399,758 ) $ 202,654 Embraer 14,320 169,586 — 183,906 Total $ 68,022 $ 718,296 $ (399,758 ) $ 386,560 March 31, 2016 Inventory Capitalized Pre-Production Forward Loss Provision Total Inventory, net Bombardier $ 6,662 $ 406,147 $ (399,758 ) $ 13,051 Embraer 5,139 146,765 — 151,904 Total $ 11,801 $ 552,912 $ (399,758 ) $ 164,955 During the fiscal year ended March 31, 2016 , the Company recorded a $399,758 forward loss charge for the Bombardier Global 7000/8000 wing program. Under our contract for this program, the Company has the right to design, develop and manufacture wing components over the initial 300 ship sets. The Global 7000/8000 contract provides for fixed pricing and requires the Company to fund certain up-front development expenses, with certain milestone payments made by Bombardier. The Global 7000/8000 program charge resulted in the impairment of previously capitalized pre-production costs due to the combination of cost recovery uncertainty, higher than anticipated non-recurring costs and increased forecasted costs on recurring production. The increases in costs were driven by several factors, including: changing technical requirements, increased spending on the design and engineering phase of the program, and uncertainty regarding cost reduction and cost recovery initiatives with our customer and suppliers. The program has continued to incur costs since March 2016 in support of the development and transition to production and the Company is in commercial discussions with Bombardier regarding recovery of those costs. Further cost increases, or an inability to meet revised recurring cost forecasts, or an inability to reach a favorable resolution of cost recovery on the Global 7000/8000 program will likely result in additional forward loss reserves in future periods, while improvements in future costs compared to current estimates or additional cost recovery may result in favorable adjustments if forward loss reserves are no longer required. The Company is still in the pre-production stages for the Bombardier and Embraer programs, as these aircrafts are not scheduled to enter service until 2018, or later. Transition of these programs from development to recurring production levels is dependent upon the success of the programs at achieving flight testing and certification, as well as the ability of the Bombardier and Embraer programs to generate acceptable levels of aircraft sales. The failure to achieve these milestones and level of sales or significant cost overruns may result in additional forward losses.

Specifically, the Existing Credit Agreement was amended to, among other things, (i) modify certain financial covenants to allow for the add-back of certain cash and non-cash charges, (ii) increase the maximum permitted total leverage ratio and senior secured leverage ratio financial covenants commencing with the fiscal quarter ended September 30, 2016 through the fiscal quarter ending June 30, 2017, (iii) permit the sale of certain specified assets so long as the Company applies 65.0% of the net proceeds received from such sales to the outstanding term loan, pro rata across all maturities, (iv) establish a new higher pricing tier for the interest rate, commitment fee and letter of credit fee pricing provisions, (v) increase the interest rate and letter of credit fee pricing provisions for several of the lower tiers of the pricing grid, (vi) establish the interest rate, commitment fee and letter of credit fee pricing at the highest pricing tier until the Company delivers its compliance certificate for its fiscal quarter ending September 30, 2017, and (vii) extend the period during which the increased minimum revolver availability threshold test and the decreased maximum senior secured leverage ratio threshold test are in effect in connection with the Company making certain permitted investments, certain additional permitted dividends, permitted acquisitions and permitted payments of certain types of indebtedness to the date the Company delivers its compliance certificate for the fiscal quarter ending September 30, 2017 In May 2016, the Company entered into a Sixth Amendment to the Third Amended and Restated Credit Agreement, among the Company, the Subsidiary Co-Borrowers, the lenders party thereto and the Administrative Agent (the “Sixth Amendment” and the Credit Facility, as amended by the Sixth Amendment, the “Credit Facility”), pursuant to which those lenders electing to enter into the Sixth Amendment extended the expiration date for the revolving line of credit and the maturity date for the term loan by five years to May 3, 2021. Lenders holding revolving credit commitments aggregating $940,000 elected to extend the expiration date for the revolving line of credit, and Lenders holding approximately $324,500 of term loans (out of an aggregate outstanding term loan balance of approximately $330,000 ) elected to extend the term loan maturity date. In connection with the amendment to the Credit Facility, the Company incurred $5,126 of financing costs. These costs, along with the $4,626 of unamortized financing costs prior to the amendment, are being amortized over the remaining term of the Credit Facility. In addition, the Sixth Amendment amended the Credit Facility to, among other things, (i) modify certain financial covenants to allow for the add-back of certain cash and non-cash charges, (ii) amend the total leverage ratio financial covenant to provide for a gradual reduction in the maximum permitted total leverage ratio commencing with the fiscal year ending March 31, 2018, (iii) increase the interest rate, commitment fee and letter of credit fee pricing provisions for the highest pricing tier, (iv) establish the interest rate, commitment fee and letter of credit fee pricing at the highest pricing tier until the Company delivers its compliance certificate for its fiscal year ending March 31, 2017, (v) increase the minimum revolver availability threshold test in connection with the Company making certain permitted investments, certain additional permitted dividends, permitted acquisitions and permitted payments of certain types of indebtedness, and (vi) decrease the maximum senior secured leverage ratio threshold test in connection with the Company making certain permitted investments, certain permitted dividends, permitted acquisitions and permitted payments of certain types of indebtedness during the period from the date of the Sixth Amendment until the Company delivers its compliance certificate for the fiscal year ending March 31, 2017. In May 2014, the Company amended the Credit Facility with its lenders to (i) increase the maximum amount allowed for the receivable securitization facility (the “Securitization Facility”) and (ii) amend certain other terms and covenants. In November 2013, the Company amended and restated its existing Credit Facility with its lenders to: (i) provide for a $375,000 Term Loan with a maturity date of May 14, 2019 (the "2013 Term Loan"); (ii) maintain a Revolving Line of Credit under the Credit Facility of $1,000,000 with a $250,000 accordion feature; (iii) extend the maturity date to November 19, 2018; and (iv) amend certain other terms and covenants. The Company will repay the outstanding principal amount of the 2013 Term Loan in quarterly installments, on the first business day of each January, April, July and October, commencing April 2014. The obligations under the Credit Facility and related documents are secured by liens on substantially all assets of the Company and its domestic subsidiaries pursuant to a Second Amended and Restated Guarantee and Collateral Agreement, dated as of November 19, 2013, among the administrative agent, the Company and the subsidiaries of the Company party thereto. Pursuant to the Credit Facility, the Company can borrow, repay and re-borrow revolving credit loans, and cause to be issued letters of credit, in an aggregate principal amount not to exceed $1,000,000 outstanding at any time. The Credit Facility bears interest at either: (i) LIBOR plus between 1.38% and 2.50% ; (ii) the prime rate; or (iii) an overnight rate at the option of the Company. The applicable interest rate is based upon the Company’s ratio of total indebtedness to earnings before interest, taxes, depreciation and amortization. In addition, the Company is required to pay a commitment fee of between 0.25% and 0.45% on the unused portion of the Credit Facility. The Company’s obligations under the Credit Facility are guaranteed by the Company’s domestic subsidiaries. At December 31, 2016 , there were $456,121 in borrowings and $27,888 in letters of credit outstanding under the Revolving Line of Credit provisions of the Credit Facility, primarily to support insurance policies. At March 31, 2016 , there were $140,000 in borrowings and $25,709 in letters of credit outstanding under the Revolving Line of Credit provisions of the Credit Facility, primarily to support insurance policies. The level of unused borrowing capacity under the Revolving Line of Credit provisions of the Credit Facility varies from time to time depending in part upon its compliance with financial and other covenants set forth in the related agreement. The Credit Facility contains certain affirmative and negative covenants, including limitations on specified levels of indebtedness to earnings before interest, taxes, depreciation and amortization, and interest coverage requirements, and includes limitations on, among other things, liens, mergers, consolidations, sales of assets, and incurrence of debt. If an event of default were to occur under the Credit Facility, the lenders would be entitled to declare all amounts borrowed under it immediately due and payable. The occurrence of an event of default under the Credit Facility could also cause the acceleration of obligations under certain other agreements. The Company is currently in compliance with all such covenants. Although the Company does not anticipate any violations of the financial covenants, its ability to comply with these covenants is dependent upon achieving earnings and cash flow projections. As of December 31, 2016 , the Company had borrowing capacity under this facility of $248,829 after reductions for borrowings, letters of credit outstanding under the facility and consideration of covenant limitations. In connection with the Company amending and restating the Credit Facility to add the 2013 Term Loan, the Company also entered into an interest rate swap agreement through November 2018 to reduce its exposure to interest on the variable rate portion of its long-term debt. On the date of inception, the Company designated the interest rate swap as a cash flow hedge in accordance with FASB guidance on accounting for derivatives and hedges and linked the interest rate swap to the 2013 Term Loan. The Company formally documented the hedging relationship between the 2013 Term Loan and the interest rate swap, as well as its risk-management objective and strategy for undertaking the hedge, the nature of the risk being hedged, how the hedging instrument's effectiveness will be assessed and a description of the method of measuring the ineffectiveness. The Company also formally assesses, both at the hedge's inception and on a quarterly basis, whether the derivative item is highly effective in offsetting changes in cash flows. As of December 31, 2016 and March 31, 2016 , the interest rate swap agreement had a notional amount of $316,406 and $337,500 , respectively. As of December 31, 2016 and March 31, 2016 , the interest rate swap agreement had a fair value of $552 and $4,526 , respectively, which is recorded in other noncurrent liabilities with an offset to other comprehensive income, net of applicable taxes (Level 2). The interest rate swap settles on a monthly basis when interest payments are made. These settlements occur through the maturity date. Receivables Securitization Facility In November 2014, the Company amended its Securitization Facility, increasing the purchase limit from $175,000 to $225,000 and extending the term through November 2017. In connection with the Securitization Facility, the Company sells on a revolving basis certain trade accounts receivable to Triumph Receivables, LLC, a wholly-owned special-purpose entity, which in turn sells a percentage ownership interest in the receivables to commercial paper conduits sponsored by financial institutions. The Company is the servicer of the trade accounts receivable under the Securitization Facility. As of December 31, 2016 , the maximum amount available under the Securitization Facility was $225,000 . Interest rates are based on LIBOR plus a program fee and a commitment fee. The program fee is 0.40% on the amount outstanding under the Securitization Facility. Additionally, the commitment fee is 0.40% on 100.00% of the maximum amount available under the Securitization Facility. At December 31, 2016 , there was $140,300 outstanding under the Securitization Facility. In connection with amending the Securitization Facility, the Company incurred approximately $252 of financing costs. These costs, along with the $341 of unamortized financing costs prior to the amendment, are being amortized over the life of the Securitization Facility. The Company secures its trade accounts receivable, which are generally non-interest bearing, in transactions that are accounted for as borrowings pursuant to the Transfers and Servicing topic of the ASC 860. The Securitization Facility is classified within the current portion of long term debt on the accompanying Condensed Consolidated Balance Sheet at December 31, 2016. The Securitization Facility's net availability is not impacted by the borrowing capacity of the Credit Facility. The agreement governing the Securitization Facility contains restrictions and covenants, including limitations on the making of certain restricted payments, creation of certain liens, and certain corporate acts such as mergers, consolidations and the sale of all or substantially all of the Company's assets. Capital Leases During the nine months ended December 31, 2016 and 2015 , the Company financed $11,504 and $13 , respectively, of property and equipment additions through capital leases. During the nine months ended December 31, 2015 , the Company obtained financing for existing fixed assets in the amount of $6,497 . Senior Notes Due 2021 On February 26, 2013, the Company issued $375,000 principal amount of 4.875% Senior Notes due 2021 (the "2021 Notes"). The 2021 Notes were sold at 100% of principal amount and have an effective interest yield of 4.875% . Interest on the 2021 Notes accrues at the rate of 4.875% per annum and is payable semiannually in cash in arrears on April 1 and October 1 of each year, commencing on October 1, 2013. In connection with the issuance of the 2021 Notes, the Company incurred approximately $6,327 of costs, which are a direct deduction to the face amount of the note and are being amortized on the effective interest method over the term of the 2021 Notes. During the quarter ended June 30, 2016, to ensure that the Company had full access to our Credit Facility during fiscal 2017, the Company obtained approval from the holders of the 2021 Notes to amend the terms of the indenture to conform with the 2022 Notes (as defined below) which allows for a higher level of secured debt. Absent this consent, the Company would have been restricted as to the level of new borrowings under the Credit Facility during fiscal 2017. As part of obtaining the consent, the Company paid the holders of the 2021 Notes $5,466 , which is being amortized on the effective interest method over the remaining term of the 2021 Notes. Further, to mitigate the risk of failing to obtain the consent and to ensure the Company had adequate liquidity through fiscal 2017, the Company chose to make a significant draw on the Credit Facility in early April 2016, taking the outstanding balance to approximately $800,000 . The Company paid down substantially all of the draw to the Credit Facility upon receiving consent from the holders of the 2021 Notes in May 2016. The 2021 Notes are the Company's senior unsecured obligations and rank equally in right of payment with all of its other existing and future senior unsecured indebtedness and senior in right of payment to all of its existing and future subordinated indebtedness. The 2021 Notes are guaranteed on a full, joint and several basis by each of the Guarantor Subsidiaries. The Company may redeem some or all of the 2021 Notes prior to April 1, 2017, by paying a "make-whole" premium. The Company may redeem some or all of the 2021 Notes on or after April 1, 2017, at specified redemption prices. In addition, prior to April 1, 2016, the Company may redeem up to 35% of the 2021 Notes with the net proceeds of certain equity offerings at a redemption price equal to 104.875% of the aggregate principal amount plus accrued and unpaid interest, if any, subject to certain limitations set forth in the indenture governing the 2021 Notes (the "2021 Indenture"). The Company is obligated to offer to repurchase the 2021 Notes at a price of (i) 101% of their principal amount plus accrued and unpaid interest, if any, as a result of certain change-of-control events, and (ii) 100% of their principal amount plus accrued and unpaid interest, if any, in the event of certain asset sales. These restrictions and prohibitions are subject to certain qualifications and exceptions. The 2021 Indenture contains covenants that, among other things, limit the Company's ability and the ability of any of the Guarantor Subsidiaries to (i) grant liens on its assets, (ii) make dividend payments, other distributions or other restricted payments, (iii) incur restrictions on the ability of the Guarantor Subsidiaries to pay dividends or make other payments, (iv) enter into sale and leaseback transactions, (v) merge, consolidate, transfer or dispose of substantially all of their assets, (vi) incur additional indebtedness, (vii) use the proceeds from sales of assets, including capital stock of restricted subsidiaries, and (viii) enter into transactions with affiliates. Senior Notes Due 2022 On June 3, 2014, the Company issued $300,000 principal amount of 5.250% Senior Notes due 2022 (the "2022 Notes"). The 2022 Notes were sold at 100% of principal amount and have an effective interest yield of 5.250% . Interest on the 2022 Notes accrues at the rate of 5.250% per annum and is payable semiannually in cash in arrears on June 1 and December 1 of each year, commencing on December 1, 2014.

The 2022 Notes are the Company's senior unsecured obligations and rank equally in right of payment with all of its other existing and future senior unsecured indebtedness and senior in right of payment to all of its existing and future subordinated indebtedness. The 2022 Notes are guaranteed on a full, joint and several basis by each of the Guarantor Subsidiaries. The Company may redeem some or all of the 2022 Notes prior to June 1, 2017, by paying a "make-whole" premium. The Company may redeem some or all of the 2022 Notes on or after June 1, 2017, at specified redemption prices. In addition, prior to June 1, 2017, the Company may redeem up to 35% of the 2022 Notes with the net proceeds of certain equity offerings at a redemption price equal to 105.250% of the aggregate principal amount plus accrued and unpaid interest, if any, subject to certain limitations set forth in the indenture governing the 2022 Notes (the "2022 Indenture").

Receivables Purchase Agreement On March 28, 2016, the Company entered into a Purchase Agreement ("Receivables Purchase Agreement") to sell certain accounts receivables to a financial institution without recourse. The Company is the servicer of the accounts receivable under the Receivables Purchase Agreement. As of March 31, 2016, the maximum amount available under the Receivables Purchase Agreement was $90,000 . Interest rates are based on LIBOR plus 0.65% - 0.70% . As of December 31, 2016 and March 31, 2016 , the Company sold $88,666 and $89,900 , respectively, worth of eligible accounts receivable.

Income Tax Disclosure [Abstract]
INCOME TAXES	The Company follows the Income Taxes topic of the ASC 740, which prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, as well as guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company has classified uncertain tax positions as noncurrent income tax liabilities unless expected to be paid in one year. Penalties and tax-related interest expense are reported as a component of income tax expense. As of December 31, 2016 and March 31, 2016 , the total amount of accrued income tax-related interest and penalties was $271 and $239 , respectively. As of December 31, 2016 and March 31, 2016 , the total amount of unrecognized tax benefits was $9,930 and $9,212 , respectively, of which $9,930 and $9,212 , respectively, would impact the effective rate, if recognized. The Company does not anticipate that total unrecognized tax benefits will be reduced in the next 12 months. As of December 31, 2016 , the Company has a valuation allowance against substantially all of its net deferred tax assets given insufficient positive evidence to support the realization of the Company’s deferred tax assets. The Company intends to continue maintaining a valuation allowance on its deferred tax assets until there is sufficient positive evidence to support the reversal of all or some portion of these allowances. A reduction in the valuation allowance could result in a significant decrease in income tax expense in the period that the release is recorded. However, the exact timing and amount of the reduction in its valuation allowance is unknown at this time and will be subject to the earnings level the Company achieves during fiscal 2017 as well as the Company's projected income in future periods. The effective income tax rate for the three months ended December 31, 2016 , was 17.3% as compared to 37.6% for the three months ended December 31, 2015 . For the three months ended December 31, 2016 , the income tax provision reflected the partial reversal of previously established valuation allowance related to the capital loss generated from the divestiture of TAS-Newport News.

Compensation and Retirement Disclosure [Abstract]
PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS	PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS The Company sponsors several defined benefit pension plans covering some of its employees. Certain employee groups are ineligible to participate in the plans or have ceased to accrue additional benefits under the plans based upon their service to the Company or years of service accrued under the defined benefit pension plans. Benefits under the defined benefit plans are based on years of service and, for most non-represented employees, on average compensation for certain years. It is the Company’s policy to fund at least the minimum amount required for all qualified plans, using actuarial cost methods and assumptions acceptable under U.S. Government regulations, by making payments into a separate trust. In addition to the defined benefit pension plans, the Company provides certain healthcare and life insurance benefits for eligible retired employees. Such benefits are unfunded. Employees achieve eligibility to participate in these contributory plans upon retirement from active service if they meet specified age and years of service requirements. Election to participate for some employees must be made at the date of retirement. Qualifying dependents at the date of retirement are also eligible for medical coverage. Current plan documents reserve the right to amend or terminate the plans at any time, subject to applicable collective bargaining requirements for represented employees. From time to time, changes have been made to the benefits provided to various groups of plan participants. Premiums charged to most retirees for medical coverage prior to age 65 are based on years of service and are adjusted annually for changes in the cost of the plans as determined by an independent actuary. In addition to this medical inflation cost-sharing feature, the plans also have provisions for deductibles, co-payments, coinsurance percentages, out-of-pocket limits, schedules of reasonable fees, preferred provider networks, coordination of benefits with other plans and a Medicare carve-out. In accordance with the Compensation – Retirement Benefits topic of ASC 715, the Company has recognized the funded status of the benefit obligation as of the date of the last remeasurement, on the accompanying Condensed Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of the plan’s assets and the pension benefit obligation or accumulated postretirement benefit obligation, of the plan. In order to recognize the funded status, the Company determined the fair value of the plan assets. The majority of the plan assets are publicly traded investments which were valued based on the market price as of the date of remeasurement. Investments that are not publicly traded were valued based on the estimated fair value of those investments based on our evaluation of data from fund managers and comparable market data. Net Periodic Benefit Plan Costs The components of net periodic benefit costs (income) for our postretirement benefit plans are shown in the following table: Pension benefits Three Months Ended December 31, Nine Months Ended December 31, 2016 2015 2016 2015 Components of net periodic benefit costs: Service cost $ 1,628 $ 2,723 $ 4,911 $ 8,216 Interest cost 18,144 22,739 54,494 68,171 Expected return on plan assets (38,966 ) (40,820 ) (117,025 ) (122,529 ) Amortization of prior service credits (445 ) (1,059 ) (1,337 ) (3,264 ) Amortization of net loss 3,027 2,467 9,088 7,457 Curtailment charge — — — 2,863 Net periodic benefit income $ (16,612 ) $ (13,950 ) $ (49,869 ) $ (39,086 ) Other postretirement benefits Three Months Ended December 31, Nine Months Ended December 31, 2016 2015 2016 2015 Components of net periodic benefit costs: Service cost $ 179 $ 297 $ 537 $ 929 Interest cost 1,247 2,011 3,740 6,137 Amortization of prior service credits (3,366 ) (1,873 ) (10,097 ) (4,668 ) Amortization of gain (1,647 ) (1,770 ) (4,941 ) (5,071 ) Net periodic benefit income $ (3,587 ) $ (1,335 ) $ (10,761 ) $ (2,673 ) The Company periodically experiences events or makes changes to its benefit plans that result in special charges. Some require remeasurements. The following summarizes the key events whose effects on net periodic benefit costs are included in the tables above: • In April 2015, the Company's largest union-represented group of employees ratified a new collective bargaining agreement. The agreement includes an amendment to the retirement plan, for which actively employed participants will no longer continue to accrue a benefit after 30 years of service. This change resulted in a curtailment charge of approximately $2,863 and is presented on the accompanying Condensed Consolidated Statements of Income as "Curtailment charge."

Certain of these awards contain performance conditions, in addition to service conditions. The fair value of the awards is expensed over a graded vesting period of the requisite service period of four to seven years. In addition the employment agreement included 150,000 stock options with an exercise price of $30.86 , a contractual term of 10 years and vesting over a 4 -year period.

SEGMENTS

Segment Reporting [Abstract]
SEGMENTS	SEGMENTS Effective April 2016, the Company realigned into four reportable segments: the Integrated Systems, the Aerospace Structures, the Precision Components and the Product Support. The Company’s reportable segments are aligned with how the business is managed and views the markets that the Company serves. The Chief Operating Decision Maker (the "CODM") evaluates performance and allocates resources based upon review of segment information. The CODM utilizes earnings before interest, income taxes, depreciation and amortization (“Adjusted EBITDA”) as a primary measure of segment profitability to evaluate performance of its segments and allocate resources. Integrated Systems consists of the Company’s operations that provides integrated solutions including design, development and support of proprietary components, subsystems and systems, as well as production of complex assemblies using external designs. Capabilities include hydraulic, mechanical and electro-mechanical actuation, power and control; a complete suite of aerospace gearbox solutions including engine accessory gearboxes and helicopter transmissions; active and passive heat exchange technology; fuel pumps, fuel metering units and Full Authority Digital Electronic Control fuel systems; hydro-mechanical and electromechanical primary and secondary flight controls; and a broad spectrum of surface treatment options. Aerospace Structures consists of the Company’s operations that supply commercial, business, regional and military manufacturers with large metallic and composite structures. Products include wings, wing boxes, fuselage panels, horizontal and vertical tails and sub-assemblies such as floor grids. Inclusive of most of the former Vought Aircraft Division, Aerospace Structures also has the capability to engineer detailed structural designs in metal and composites. Precision Components consists of the Company’s operations that produce close-tolerance parts primarily to customer designs and model-based definition, including a wide range of aluminum, hard metal and composite structure capabilities. Capabilities include complex machining, gear manufacturing, sheet metal fabrication, forming, advanced composite and interior structures, joining processes such as welding, autoclave bonding and conventional mechanical fasteners and a variety of special processes including: super plastic titanium forming, aluminum and titanium chemical milling and surface treatments. Product Support consists of the Company’s operations that provide full life cycle solutions for commercial, regional and military aircraft. The Company’s extensive product and service offerings include full post-delivery value chain services that simplify the MRO supply chain. Through its line maintenance, component MRO and postproduction supply chain activities, Product Support is positioned to provide integrated planeside repair solutions globally. Capabilities include fuel tank repair, metallic and composite aircraft structures, nacelles, thrust reversers, interiors, auxiliary power units and a wide variety of pneumatic, hydraulic, fuel and mechanical accessories. Segment Adjusted EBITDA is total segment revenue reduced by operating expenses (less depreciation and amortization) identifiable with that segment. Corporate includes general corporate administrative costs and any other costs not identifiable with one of the Company’s segments, including a loss on divestiture of $19,124 for the nine months ended December 31, 2016 . The Company does not accumulate net sales information by product or service or groups of similar products and services and, therefore, the Company does not disclose net sales by product or service because to do so would be impracticable. Selected financial information for each reportable segment and the reconciliation of Adjusted EBITDA to operating income is as follows: Three Months Ended December 31, Nine Months Ended December 31, 2016 2015 2016 2015 Net sales: Integrated Systems $ 256,080 $ 271,849 $ 758,803 $ 791,901 Aerospace Structures 304,235 346,639 956,114 1,127,230 Precision Components 226,294 250,284 740,354 781,250 Product Support 87,292 78,127 257,317 226,649 Elimination of inter-segment sales (29,038 ) (33,033 ) (99,703 ) (98,752 ) $ 844,863 $ 913,866 $ 2,612,885 $ 2,828,278 Income before income taxes: Operating income (expense): Integrated Systems $ 51,596 $ 52,321 $ 145,379 $ 153,978 Aerospace Structures 23,867 (210,938 ) 57,898 (132,458 ) Precision Components 2,942 24,106 7,223 74,468 Product Support 14,662 12,402 42,986 31,514 Corporate (37,901 ) (4,141 ) (81,107 ) (35,839 ) 55,166 (126,250 ) 172,379 91,663 Interest expense and other 19,698 15,792 55,721 49,539 $ 35,468 $ (142,042 ) $ 116,658 $ 42,124 Depreciation and amortization: Integrated Systems $ 9,766 $ 10,659 $ 30,228 $ 31,316 Aerospace Structures 17,942 16,066 54,289 47,645 Precision Components 13,999 11,407 42,344 39,600 Product Support 2,294 2,462 7,230 7,352 Corporate 330 434 989 1,224 $ 44,331 $ 41,028 $ 135,080 $ 127,137 Impairment charge of intangible assets: Aerospace Structures $ — $ 229,200 $ — $ 229,200 Amortization of acquired contract liabilities, net: Integrated Systems $ 7,628 $ 9,804 $ 27,101 $ 30,316 Aerospace Structures 21,105 23,831 60,190 67,039 Precision Components 473 790 1,740 2,573 $ 29,206 $ 34,425 $ 89,031 $ 99,928 Three Months Ended December 31, Nine Months Ended December 31, 2016 2015 2016 2015 Adjusted EBITDA: Integrated Systems $ 53,734 $ 53,176 $ 148,506 $ 154,978 Aerospace Structures 20,704 20,997 51,997 87,848 Precision Components 16,468 34,723 47,827 111,495 Product Support 16,956 16,764 50,216 40,766 Corporate (23,221 ) (3,707 ) (60,994 ) (31,752 ) $ 84,641 $ 121,953 $ 237,552 $ 363,335 Capital expenditures: Integrated Systems $ 2,763 $ 10,444 $ 8,586 $ 20,309 Aerospace Structures 2,228 8,028 9,820 23,494 Precision Components 2,636 5,853 11,040 16,979 Product Support 687 714 2,020 2,047 Corporate 843 196 1,657 534 $ 9,157 $ 25,235 $ 33,123 $ 63,363 December 31, 2016 March 31, 2016 Total Assets: Integrated Systems $ 1,300,195 $ 1,371,178 Aerospace Structures 1,923,301 1,792,397 Precision Components 1,263,536 1,298,294 Product Support 340,642 350,674 Corporate 31,246 22,550 $ 4,858,920 $ 4,835,093 During the three months ended December 31, 2016 and 2015 , the Company had international sales of $198,052 and $194,425 , respectively.

Commitments and Contingencies [Abstract]
Commitments and Contingencies Disclosure [Text Block]	COMMITMENTS AND CONTINGENCIES On December 22, 2016, Triumph Aerostructures, LLC, a wholly owned subsidiary of the Company (“Triumph Aerostructures”), initiated litigation against Bombardier Inc. (“Bombardier”), a customer of Triumph Aerostructures, in the Quebec Superior Court, District of Montreal. The lawsuit relates to Bombardier’s failure to pay to Triumph Aerostructures certain non-recurring expenses incurred by Triumph Aerostructures during the development phase of a program pursuant to which Triumph Aerostructures agreed to design, manufacture, and supply the wing and related components for Bombardier’s Global 7000 business aircraft. The lawsuit seeks a monetary award of approximately US $340,000 (or CAD $455,000 ) resulting from Bombardier directed changes to the original wing requirements for the Global 7000 program, as well as Bombardier’s, delays, disruptions, acceleration and interference in connection with its contract with Triumph Aerostructures. In the meantime, Triumph Aerostructures continues to support the Global 7000 program and to seek a resolution of its disputes. In the ordinary course of business, the Company is involved in disputes, claims and lawsuits with employees, suppliers and customers, as well as governmental and regulatory inquiries, that it deems to be immaterial. Some may involve claims or potential claims of substantial damages, fines, penalties or injunctive relief. While the Company cannot predict the outcome of any pending or future litigation or proceeding and no assurances can be given, the Company does not believe that any pending matter will have a material effect, individually or in the aggregate, on its financial position or results of operations.

RESTRUCTURING COSTS Fiscal 2016 Restructuring During the fiscal year ended March 31, 2016, the Company committed to a restructuring of certain of its businesses as well as the consolidation of certain of its facilities ("2016 Restructuring Plan"). The Company expects to reduce its footprint by approximately 3.5 million square feet and to reduce head count by 1,200 employees. Over the next few fiscal years, the Company estimates that it will record aggregate pre-tax charges of $150,000 to $160,000 related to these programs, which represent employee termination benefits, contract termination costs, accelerated depreciation and facility closure and other exit costs, and will result in future cash outlays. For the three months ended December 31, 2016 , the Company recorded charges of $14,132 related to this program including, accelerated depreciation of $3,065 and severance of $551 . For the nine months ended December 31, 2016 , the Company recorded charges of $38,476 related to this program including, accelerated depreciation of $10,296 and severance of $1,649 .

SUMMARY OF SIGNIFICANT ACCOUN23

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition Revenues are generally recognized in accordance with the contract terms when products are shipped, delivery has occurred or services have been rendered, pricing is fixed and determinable, and collection is reasonably assured. A significant portion of the Company’s contracts are within the scope of the Revenue Recognition - Construction-Type and Production-Type Contracts topic of the Accounting Standards Codification ("ASC") 605-35 and revenue and costs on contracts are recognized using the percentage-of-completion method of accounting. Accounting for the revenue and profit on a contract requires estimates of (1) the contract value or total contract revenue, (2) the total costs at completion, which is equal to the sum of the actual incurred costs to date on the contract and the estimated costs to complete the contract’s scope of work, and (3) the measurement of progress toward completion. Depending on the contract, the Company measures progress toward completion using either the cost-to-cost method or the units-of-delivery method of accounting, with the great majority measured under the units-of-delivery method of accounting. • Under the cost-to-cost method of accounting, progress toward completion is measured as the ratio of total costs incurred to estimated total costs at completion. Costs are recognized as incurred. Profit is determined based on estimated profit margin on the contract multiplied by the progress toward completion. Revenue represents the sum of costs and profit on the contract for the period. • Under the units-of-delivery method of accounting, revenue on a contract is recorded as the units are delivered and accepted during the period at an amount equal to the contractual selling price of those units. The costs recorded on a contract under the units-of-delivery method of accounting are equal to the total costs at completion divided by the total units to be delivered. As contracts can span multiple years, the Company often segments the contracts into production lots for the purposes of accumulating and allocating cost. Profit is recognized as the difference between revenue for the units delivered and the estimated costs for the units delivered. Adjustments to original estimates for a contract’s revenues, estimated costs at completion and estimated total profit are often required as work progresses under a contract, as experience is gained and as more information is obtained, even though the scope of work required under the contract may not change, or if contract modifications occur. These estimates are also sensitive to the assumed rate of production. Generally, the longer it takes to complete the contract quantity, the more relative overhead that contract will absorb. The impact of revisions in cost estimates is recognized on a cumulative catch-up basis in the period in which the revisions are made. Provisions for anticipated losses on contracts are recorded in the period in which they become evident (‘‘forward losses’’) and are first offset against costs that are included in inventory, with any remaining amount reflected in accrued contract liabilities in accordance with the Revenue Recognition - Construction-Type and Production-Type Contracts topic. Revisions in contract estimates, if significant, can materially affect results of operations and cash flows, as well as valuation of inventory. Furthermore, certain contracts are combined or segmented for revenue recognition in accordance with the Revenue Recognition - Construction-Type and Production-Type Contracts topic. During the quarter ended September 30, 2016, the Company discovered an immaterial error in its percentage-of-completion accounting for one of its contracts, which understated cost of sales and overstated net income for the three months ended June 30, 2016, in the amount of $11,800 and $8,142 , respectively and overstated retained earnings as of March 31, 2016, in the amount of $12,700 . The Company assessed the materiality of this error on previously issued financial statements in accordance with the ASC 250, Presentation of Financial Statements , and Securities and Exchange Commission (SEC) Staff Accounting Bulletin No. 99, Materiality. The Company concluded, based on a review of the quantitative and qualitative factors of the materiality of the amount, that the error was not material to any previously issued financial statements and the correction of the error in the three months ended September 30, 2016 was not material to that period’s financial statements. Accordingly, in order to correct this immaterial error, the Company has recorded a charge to "Cost of sales" in the amount of $24,500 , which is presented on the accompanying Condensed Consolidated Statements of Income during the nine months ended December 31, 2016 . For the three months ended December 31, 2016 , cumulative catch-up adjustments from changes in estimates, inclusive of changes in forward loss estimates, increased operating income, net income and earnings per share by approximately $2,131 , $1,762 and $0.04 , net of tax, respectively. The cumulative catch-up adjustments to operating income for the three months ended December 31, 2016 , included gross favorable adjustments of approximately $9,663 and gross unfavorable adjustments of approximately $(7,532) . For the three months ended December 31, 2015 , cumulative catch-up adjustments from changes in estimates decreased operating income, net income and earnings per share by approximately $(2,846) , $(1,776) and $(0.04) , net of tax, respectively. For the nine months ended December 31, 2016 , cumulative catch-up adjustments from changes in estimates, inclusive of changes in forward loss estimates and the correction of the error noted above, decreased operating income, net income and earnings per share by approximately $(6,290) , $(4,522) and $(0.09) , net of tax, respectively. The cumulative catch-up adjustments to operating income for the nine months ended December 31, 2016 , included gross favorable adjustments of approximately $50,180 and gross unfavorable adjustments of approximately $(56,470) , which includes a reduction to the previously recognized forward losses on the 747-8 program of $41,300 . For the nine months ended December 31, 2015 , cumulative catch-up adjustments from changes in estimates decreased operating income, net income and earnings per share by approximately $(13,796) , $(11,690) and $(0.24) , net of tax, respectively. Amounts representing contract change orders or claims are only included in revenue when such change orders or claims have been settled with the customer and to the extent that units have been delivered. Additionally, some contracts may contain provisions for revenue sharing, price re-determination, requests for equitable adjustments, change orders or cost and/or performance incentives. Such amounts or incentives are included in contract value when the amounts can be reliably estimated and their realization is reasonably assured. Although fixed-price contracts, which extend several years into the future, generally permit the Company to keep unexpected profits if costs are less than projected, the Company also bears the risk that increased or unexpected costs may reduce profit or cause the Company to sustain losses on the contract. In a fixed-price contract, the Company must fully absorb cost overruns, notwithstanding the difficulty of estimating all of the costs the Company will incur in performing these contracts and in projecting the ultimate level of revenue that may otherwise be achieved. As disclosed during fiscal 2016, the Company recognized a provision for forward losses associated with our long-term contract on the 747-8 and Bombardier programs. There is still risk similar to what the Company has experienced on the 747-8 and Bombardier programs. Particularly, the Company's ability to manage risks related to supplier performance, execution of cost reduction strategies, hiring and retaining skilled production and management personnel, quality and manufacturing execution, program schedule delays, potential need to negotiate facility lease extensions or alternatively relocate work and many other risks, will determine the ultimate performance of these programs. Included in net sales of Integrated Systems, Aerospace Structures and Precision Components is the non-cash amortization of acquired contract liabilities that were recognized as fair value adjustments through purchase accounting from various acquisitions. For the three months ended December 31, 2016 and 2015 , the Company recognized $29,206 and $34,425 , respectively, into net sales on the accompanying Condensed Consolidated Statements of Income. For the nine months ended December 31, 2016 and 2015 , the Company recognized $89,031 and $99,928 , respectively, into net sales on the accompanying Condensed Consolidated Statements of Income. The Product Support provides repair and overhaul services, of which a small portion of services are provided under long-term power-by-the-hour contracts. The Company applies the proportional performance method of accounting to recognize revenue under these contracts. Revenue is recognized over the contract period as units are delivered based on the relative value in proportion to the total estimated contract consideration. In estimating the total contract consideration, management evaluates the projected utilization of its customers’ fleet over the term of the contract, in connection with the related estimated repair and overhaul servicing requirements to the fleet based on such utilization. Changes in utilization of the fleet by customers, among other factors, may have an impact on these estimates and require adjustments to estimates of revenue to be realized.
Concentration of Credit Risk	Concentration of Credit Risk The Company’s trade accounts receivable are exposed to credit risk. However, the risk is limited due to the diversity of the customer base and the customer base’s wide geographical area. Trade accounts receivable from Boeing (representing commercial, military and space) represented approximately 11% and 18% of total trade accounts receivable as of December 31, 2016 and March 31, 2016 , respectively. The Company had no other concentrations of credit risk of more than 10% . Sales to Boeing for the nine months ended December 31, 2016 , were $928,020 , or 36% of net sales, of which $157,772 , $427,960 , $317,426 and $24,862 were from the Integrated Systems, Aerospace Structures, Precision Components and Product Support, respectively. Sales to Boeing for the nine months ended December 31, 2015 , were $1,068,313 , or 38% of net sales, of which $146,882 , $648,380 , $247,579 and $25,472 were from the Integrated Systems, Aerospace Structures, Precision Components and Product Support, respectively. Sales to Gulfstream Aerospace Corporation for the nine months ended December 31, 2016 , were $321,671 , or 12% of net sales, of which $1,418 , $311,207 , $8,855 and $191 were from the Integrated Systems, Aerospace Structures, Precision Components and Product Support, respectively. Sales to Gulfstream for the nine months ended December 31, 2015 , were $366,710 , or 13% of net sales, of which $2,665 , $358,768 , $5,264 and $13 were from the Integrated Systems, Aerospace Structures, Precision Components and Product Support, respectively. No other single customer accounted for more than 10% of the Company’s net sales. However, the loss of any significant customer, including Boeing and Gulfstream, could have a material adverse effect on the Company and its operating subsidiaries.
Stock-Based Compensation	Stock-Based Compensation The Company recognizes compensation expense for share-based awards based on the fair value of those awards at the date of grant. Stock-based compensation expense for the three months ended December 31, 2016 and 2015 , was $2,163 and $737 , respectively. Stock-based compensation expense for the nine months ended December 31, 2016 and 2015 , was $6,140 and $1,908 , respectively.

Fair Value Measurement, Policy [Policy Text Block]	Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When determining fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing an asset or liability. The fair value hierarchy has three levels of inputs that may be used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability; and Level 3—Unobservable inputs for the asset or liability. The Company has applied fair value measurements to its interest rate swap (see Note 4 and Note 6).
Product Warranty Disclosure [Text Block]	Warranty Reserves A reserve has been established to provide for the estimated future cost of warranties on our delivered products. The Company periodically reviews the reserves and adjustments are made accordingly. A provision for warranty on products delivered is made on the basis of historical experience and identified warranty issues. Warranties cover such factors as non-conformance to specifications and defects in material and workmanship. The majority of the Company's agreements include a three -year warranty, although certain programs have warranties up to 20 years. The warranty reserves as of December 31, 2016 and March 31, 2016 , were $108,287 and $112,937 , respectively
