UNAUDITED INTERIM FINANCIAL INFOMRATION	UNAUDITED INTERIM FINANCIAL INFORMATION The financial information included herein is unaudited; however, the information reflects all adjustments (consisting of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company’s condensed consolidated financial statements for the interim periods presented. These financial statements and notes should be read in conjunction with the financial statements and related notes for the fiscal year ended September 30, 2021 included in TD Group’s Form 10-K filed on November 16, 2021. As disclosed therein, the Company’s annual consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”).

Business Combinations [Abstract]
ACQUISITIONS AND DIVESTITURES	ACQUISITIONS AND DIVESTITURES Acquisitions Cobham Aero Connectivity – On November 24, 2020, the Company entered into a definitive agreement to acquire all the outstanding stock of Chelton Limited, Chelton Avionics Holdings, Inc. and Mastsystem Int'l Oy, collectively, Cobham Aero Connectivity (“CAC”), for a total purchase price of $945 million. The acquisition was substantially completed on January 5, 2021 and financed through existing cash on hand. The Company completed the remainder of the acquisition of CAC on February 12, 2021, also through existing cash on hand. CAC operates from two primary facilities (Marlow, United Kingdom and Prescott, Arizona) and is a leading provider of highly engineered antennas and radios for the aerospace end market. The products are primarily proprietary with significant aftermarket content and have a strong presence across major defense platforms as well as select commercial applications. CAC's operating results are included within TransDigm's Airframe segment. The acquisition strengthens and expands the Company’s position to design, produce and supply highly engineered proprietary aerospace components in niche markets with significant aftermarket content and provide opportunities to create value through the application of our three core value-driven operating strategies (obtaining profitable new business, continually improving our cost structure, and providing highly engineered value-added products to customers). The purchase price paid for the acquisition reflects the current earnings before interest, taxes, depreciation and amortization (“EBITDA”) and cash flows, as well as the future EBITDA and cash flows expected to be generated by the business, which are driven in most cases by the recurring aftermarket consumption over the life of a particular aircraft, estimated to be approximately 25 to 30 years. The Company accounted for the CAC acquisition using the acquisition method of accounting and third-party valuation appraisals and included the results of operations of the acquisition in its condensed consolidated financial statements from the effective dates of the acquisition. The total purchase price of CAC was allocated to the underlying assets acquired and liabilities assumed based upon the respective fair value at the dates of acquisition. To the extent the purchase price exceeded the fair value of the net identifiable tangible and intangible assets acquired, such excess was allocated to goodwill. The fair values of acquired intangibles and certain liabilities, such as loss contract reserves, are determined based on estimates and assumptions that are deemed reasonable by the Company. Significant assumptions used to determine the fair values of acquired intangible assets include the discount rates and certain assumptions that form the basis of the forecasted results of the acquired business including revenue growth rates, EBITDA margins, royalty rates and technology obsolescence rates. Significant assumptions used to determine the fair value of the loss contract reserves using the discounted cash flow model include discount rates and forecasted costs to be incurred under the long-term contracts and at-market bid prices for respective contracts. These assumptions are forward looking and could be affected by future economic and market conditions. Pro forma net sales and results of operations for the acquisition had it occurred at the beginning of the applicable thirteen week period ended January 1, 2022 or January 2, 2021 are not material and, accordingly, are not provided. The final allocation of the fair value of assets acquired and liabilities assumed in the CAC acquisition as of the acquisition date, as well as measurement period adjustments recorded as of January 1, 2022, are summarized in the table below (in millions): Preliminary Allocation Measurement Period Adjustments Final Assets acquired (excluding cash): Trade accounts receivable $ 31 $ 1 $ 32 Inventories 27 2 29 Prepaid expenses and other 10 (3) 7 Property, plant and equipment 18 3 21 Goodwill 636 61 697 (1) Other intangible assets 309 15 324 (1) Other 34 (3) 31 Total assets acquired (excluding cash) 1,065 76 1,141 Liabilities assumed: Accounts payable 15 3 18 Accrued and other current liabilities 38 6 (2) 44 Deferred income taxes 38 (7) 31 Other non-current liabilities 29 74 (2) 103 Total liabilities assumed 120 76 196 Net assets acquired $ 945 $ — $ 945 (1) Of the approximately $697 million of goodwill recognized for the acquisition, approximately $65 million is deductible for tax purposes. Of the approximately $324 million of other intangible assets recognized for the acquisition, approximately $105 million is deductible for tax purposes. The goodwill and intangible assets are deductible over 15 years. (2) Primarily relates to the recording of loss contract reserves associated with acquired ongoing long-term contracts with customers that were incurring negative gross margins as of the date of acquisition. Based on our review of these contracts, we concluded that the terms of certain contracts were unfavorable when compared to market terms as of the acquisition date. The loss contract reserves, totaling $80.6 million, will be released over an estimated three to five year period. Divestitures ScioTeq and TREALITY Simulation Visual Systems – On June 30, 2021, TransDigm completed the divestiture of its ScioTeq and TREALITY Simulation Visual Systems businesses (“ScioTeq and TREALITY”) to OpenGate Capital for approximately $200 million in cash. ScioTeq and TREALITY were acquired by TransDigm as part of its acquisition of Esterline Technologies Corporation (“Esterline”) in March 2019 and were included in TransDigm’s Airframe segment. Neither ScioTeq or TREALITY met the criteria to be classified as held for sale as of January 2, 2021. Technical Airborne Components – On April 27, 2021, TransDigm completed the divestiture of the Technical Airborne Components business (“TAC”) to Searchlight Capital Partners for approximately $40 million in cash. TAC was included in TransDigm’s Airframe segment. TAC did not meet the criteria to be classified as held for sale as of January 2, 2021. The net gain on sale recognized in fiscal 2021 as a result of the ScioTeq and TREALITY and TAC divestitures was approximately $68 million, which was classified as a component of gain on sale of businesses-net within the condensed consolidated statements of income during the third quarter of fiscal 2021. Racal Acoustics – On January 29, 2021, TransDigm completed the divestiture of the Racal Acoustics business (“Racal”) to Invisio Communications AB (“Invisio”) for approximately $20 million in cash. During the first quarter of fiscal 2021, the Company determined Racal met the criteria to be classified as held for sale. Therefore, the assets and liabilities of Racal, which were not material, have been presented as held for sale in other assets, accrued and other current liabilities and other non-current liabilities, respectively, in the condensed consolidated balance sheets as of January 2, 2021. Racal was acquired by TransDigm as part of its acquisition of Esterline in March 2019 and was included in TransDigm's Non-aviation segment. Avista, Inc. – On November 17, 2020, TransDigm completed the divestiture of the Avista, Inc. business (“Avista”) to Belcan, LLC (“Belcan”) for approximately $8 million in cash. Avista was acquired by TransDigm as part of its acquisition of Esterline in March 2019 and was included in TransDigm's Airframe segment. The gain on sale recognized in the first quarter of fiscal 2021 as a result of the divestiture was immaterial and classified as a component of gain on sale of businesses-net within the condensed consolidated statements of income.

Accounting Standards Update and Change in Accounting Principle [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Accounting Standards Codification (“ASC”) 740) - Simplifying the Accounting for Income Taxes,” which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 740. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company adopted ASU 2019-12 on October 1, 2021. The adoption of this standard did not have a material impact on our condensed consolidated financial statements and disclosures. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform." Certain amendments were provided for in ASU 2021-01, “Reference Rate Reform (ASC 848): Scope,” which was issued in January 2021. This ASU provides optional guidance for a limited period of time to ease potential accounting impacts associated with transitioning away from reference rates that are expected to be discontinued, such as the London Interbank Offered Rate (“LIBOR”). The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The amendments in this ASU are effective through December 31, 2022. The Company is currently evaluating the impact of adopting this standard on our condensed consolidated financial statements and disclosures and we continue to monitor any subsequent updates impacting the transition.

REVENUE RECOGNITION

REVENUE RECOGNITION	3 Months Ended
	Jan. 01, 2022
Revenue from Contract with Customer [Abstract]
REVENUE RECOGNITION	REVENUE RECOGNITION TransDigm's sales are concentrated in the aerospace and defense industry. The Company’s customers include: distributors of aerospace components, commercial airlines, large commercial transport and regional and business aircraft OEMs, various armed forces of the United States and friendly foreign governments, defense OEMs, system suppliers, and various other industrial customers. The majority of the Company's revenue is recorded at a point in time. Revenue is recognized from the sale of products when control transfers to the customer, which is demonstrated by our right to payment, a transfer of title, a transfer of the risk and rewards of ownership, or the customer acceptance, but most frequently upon shipment where the customer obtains physical possession of the goods. In some contracts, control transfers to the customer over time, primarily in contracts where the customer is required to pay for the cost of both the finished and unfinished goods at the time of cancellation plus a reasonable profit relative to the work performed for products that were customized for the customer. Therefore, we recognize revenue over time for those agreements that have a right to margin and where the products being produced have no alternative use. Based on our production cycle, it is generally expected that goods related to the revenue will be shipped and billed within the current year. For revenue recognized over time, we estimate the amount of revenue attributable to a contract earned at a given point during the production cycle based on certain costs, such as materials and labor incurred to date, plus the expected profit, which is a cost-to-cost input method. We consider the contractual consideration payable by the customer and assess variable consideration that may affect the total transaction price. Variable consideration is included in the estimated transaction price when there is a basis to reasonably estimate the amount, including whether the estimate should be constrained in order to avoid a significant reversal of revenue in a future period. These estimates are based on historical experience, anticipated performance under the terms of the contract and our best judgment at the time. When contracts are modified to account for changes in contract specifications and requirements, the Company considers whether the modification either creates new or changes the existing enforceable rights and obligations. Contract modifications that are for goods or services that are not distinct from the existing contract, due to the significant integration with the original good or service provided, are accounted for as if they were part of that existing contract. The effect of a contract modification to an existing contract on the transaction price and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue on a cumulative catch-up basis. When the modifications include additional performance obligations that are distinct and at relative stand-alone selling price, they are accounted for as a new contract and performance obligation, which are recognized prospectively. The Company’s payment terms vary by the type and location of the customer and the products or services offered. The Company does not offer any payment terms that would meet the requirements for consideration as a significant financing component. Shipping and handling fees and costs incurred in connection with products sold are recorded in cost of sales in the condensed consolidated statements of income, and are not considered a performance obligation to our customers. The Company pays sales commissions that relate to contracts for products or services that are satisfied at a point in time or over a period of one year or less and are expensed as incurred. These costs are reported as a component of selling and administrative expenses in the condensed consolidated statements of income. Contract Assets and Liabilities – Contract assets reflect revenue recognized and performance obligations satisfied in advance of customer billing or reimbursable costs related to a specific contract. Contract liabilities relate to payments received in advance of the satisfaction of performance under the contract. We receive payments from customers based on the terms established in our contracts. The following table summarizes our contract assets and liabilities balances (in millions): January 1, 2022 September 30, 2021 Contract assets, current (1) $ 78 $ 72 Contract assets, non-current (2) 1 2 Total contract assets 79 74 Contract liabilities, current (3) 38 27 Contract liabilities, non-current (4) 8 5 Total contract liabilities 46 32 Net contract assets $ 33 $ 42 (1) Included in prepaid expenses and other on the condensed consolidated balance sheets. (2) Included in other non-current assets on the condensed consolidated balance sheets. (3) Included in accrued and other current liabilities on the condensed consolidated balance sheets. (4) Included in other non-current liabilities on the condensed consolidated balance sheets. For the thirteen week period ended January 1, 2022, the revenue recognized that was previously included in contract liabilities was not material. Refer to Note 13, “Segments,” for disclosures related to the disaggregation of revenue. Allowance for Credit Losses – The Company's allowance for credit losses is the allowance for uncollectible accounts. The allowance for uncollectible accounts reduces the trade accounts receivable balance to the estimated net realizable value equal to the amount that is expected to be collected. The Company’s method for developing its allowance for credit losses is based on historical write-off experience, the aging of receivables, an assessment of the creditworthiness of customers, economic conditions and other external market information. All provisions for allowances for uncollectible accounts are included in selling and administrative expenses. As of January 1, 2022 and September 30, 2021, the allowance for uncollectible accounts was $30 million. The allowance for uncollectible accounts is assessed individually at each operating unit by the operating unit’s management team.

Amendment No. 9 and Loan Modification Agreement – On December 29, 2021, the Company entered into Amendment No. 9 and Incremental Revolving Credit Assumption Agreement (herein, “Amendment No. 9”) to the Second Amended and Restated Credit Agreement dated as of June 4, 2014 (the “Credit Agreement”), which increases the capacity under the revolving credit facility from $760 million to $810 million. The terms and conditions that apply to Amendment No. 9 are the same as the terms and conditions that apply to the existing dollar revolving commitments and term loans under the Credit Agreement. As of January 1, 2022, the borrowings available under the revolving commitments were $776.5 million. The Company capitalized $0.2 million representing debt issuance costs associated with Amendment No. 9 during the thirteen week period ended January 1, 2022. Revolving Credit Facility – On October 6, 2021, the Company repaid $200 million previously drawn on the revolving credit facility, in addition to $0.1 million of accrued interest. Government Refundable Advances – Government refundable advances consist of payments received from the Canadian government to assist in research and development related to commercial aviation. The requirement to repay this advance is based on year-over-year commercial aviation revenue growth for certain product lines at CMC Electronics, which is a wholly-owned subsidiary of TransDigm. As of January 1, 2022 and September 30, 2021, the outstanding balance of these advances was $28 million and $29 million, respectively.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES At the end of each reporting period, TD Group makes an estimate of its annual effective income tax rate. The estimate used in the year-to-date period may change in subsequent periods. During the thirteen week periods ended January 1, 2022 and January 2, 2021, the effective income tax rate was 15.7% and 5.5%, respectively. The Company’s higher effective tax rate for the thirteen week period ended January 1, 2022 was primarily due to the ratio of the discrete impact of excess tax benefits from share-based payments to income from continuing operations being lower in the thirteen week period ended January 1, 2022 resulting from an increase in income from continuing operations before income taxes for the same thirteen week period. The Company’s effective income tax rate of 15.7% for the thirteen week period ended January 1, 2022 was lower than the federal statutory tax rate of 21%, primarily due to the discrete impact of excess tax benefits associated with share-based payments during the first quarter of fiscal 2022. The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state, local and foreign jurisdictions. The Company is no longer subject to U.S. federal examinations for years before fiscal 2017. The Company is currently under examination for its federal income taxes in Canada for fiscal years 2013 through 2019, in France for fiscal years 2018 through 2019 and in Germany for fiscal years 2014 through 2017. The Company expects the examinations in France to be completed during fiscal 2022. In addition, the Company is subject to state income tax e xaminations for fiscal years 2015 and later. Unrecognized tax benefits at January 1, 2022 and September 30, 2021, the recognition of which would have an impact on the effective tax rate for each fiscal year, amounted to $18.5 million and $19.1 million, respectively. The Company classifies all income tax-related interest and penalties as income tax expense, which were not material for the thirteen week periods ended January 1, 2022 and January 2, 2021. As of January 1, 2022 and September 30, 2021, the Company accrued $4.9 million, respectively, for the potential payment of interest and penalties. Within the next 12 months, it is reasonably possible that unrecognized tax benefits could be reduced by approximately $3.8 million. Any increase in the amount of unrecognized tax benefits within the next 12 months is not expected to be material.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTSThe following table presents our assets and liabilities that are measured at fair value on a recurring basis and 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 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The following summarizes the carrying amounts and fair values of financial instruments (in millions): January 1, 2022 September 30, 2021 Level Carrying Fair Value Carrying Fair Value Assets: Cash and cash equivalents 1 $ 4,813 $ 4,813 $ 4,787 $ 4,787 Interest rate cap agreements (1) 2 11 11 8 8 Liabilities: Interest rate swap agreements (2) 2 106 106 100 100 Interest rate swap agreements (3) 2 103 103 180 180 Foreign currency forward exchange contracts (2) 2 4 4 4 4 Short-term borrowings - trade receivable securitization facility (4) 2 350 350 349 349 Long-term debt, including current portion: Term loans (4) 2 7,302 7,216 7,318 7,268 Revolving credit facility (4) 2 — — 200 200 2025 Secured Notes (4) 1 1,093 1,159 1,093 1,170 6.375% 2026 Notes (4) 1 945 976 945 981 6.875% 2026 Notes (4) 1 494 521 494 527 2026 Secured Notes (4) 1 4,361 4,565 4,359 4,593 7.50% 2027 Notes (4) 1 546 575 546 578 5.50% 2027 Notes (4) 1 2,633 2,703 2,632 2,730 4.625% 2029 Notes (4) 1 1,190 1,188 1,190 1,196 4.875% 2029 Notes (4) 1 744 750 743 751 Government refundable advances 2 28 28 29 29 Finance lease obligations 2 128 128 100 100 (1) Included in other assets on the condensed consolidated balance sheets. (2) Included in accrued and other current liabilities on the condensed consolidated balance sheets. (3) Included in other non-current liabilities on the condensed consolidated balance sheets. (4) The carrying amount of the debt instrument is presented net of debt issuance costs, premium and discount. Refer to Note 9, “Debt,” for gross carrying amounts. The Company values its financial instruments using an industry standard market approach, in which prices and other relevant information are generated by market transactions involving identical or comparable assets or liabilities. No financial instruments were recognized or disclosed using unobservable inputs (i.e., Level 3). Interest rate swaps were measured at fair value using quoted market prices for the swap interest rate indexes over the term of the swap discounted to present value versus the fixed rate of the contract. The interest rate caps were measured at fair value using implied volatility rates of each individual caplet and the yield curve for the related periods. The Company’s derivative contracts consist of foreign currency exchange contracts and interest rate swap and cap agreements. These derivative contracts are over-the-counter, and their fair value is determined using modeling techniques that include market inputs such as interest rates, yield curves, and currency exchange rates. These contracts are categorized as Level 2 in the fair value hierarchy. The estimated fair value of the Company’s term loans was based on information provided by the agent under the Company’s senior secured credit facility. The estimated fair values of the Company’s notes were based upon quoted market prices. There has not been any impact to the fair value of derivative liabilities due to the Company's own credit risk. Similarly, there has not been any significant impact to the fair value of derivative assets based on the Company's evaluation of counterparties' credit risks. The fair value of cash and cash equivalents, trade accounts receivable-net and accounts payable approximated carrying value due to the short-term nature of these instruments at January 1, 2022 and September 30, 2021.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES AND HEDGING ACTIVITIES	DERIVATIVES AND HEDGING ACTIVITIES The Company is exposed to, among other things, the impact of changes in foreign currency exchange rates and interest rates in the normal course of business. The Company’s risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes derivative financial instruments to offset a portion of these risks. The Company uses derivative financial instruments only to the extent necessary to hedge identified business risks and does not enter into such transactions for trading purposes. The Company generally does not require collateral or other security with counterparties to these financial instruments and is therefore subject to credit risk in the event of nonperformance; however, the Company monitors credit risk and currently does not anticipate nonperformance by other parties. These derivative financial instruments do not subject the Company to undue risk, as gains and losses on these instruments generally offset gains and losses on the underlying assets, liabilities, or anticipated transactions that are being hedged. The Company has agreements with each of its swap and cap counterparties that contain a provision whereby if the Company defaults on the credit facility the Company could also be declared in default on its swaps and caps, resulting in an acceleration of payment under the swaps and caps. All derivative financial instruments are recorded at fair value in the condensed consolidated balance sheets. For a derivative that has not been designated as an accounting hedge, the change in the fair value is recognized immediately through earnings. For a derivative that has been designated as an accounting hedge of an existing asset or liability (a fair value hedge), the change in the fair value of both the derivative and underlying asset or liability is recognized immediately through earnings. For a derivative designated as an accounting hedge of an anticipated transaction (a cash flow hedge), the change in the fair value is recorded on the condensed consolidated balance sheets in accumulated other comprehensive loss to the extent the derivative is effective in mitigating the exposure related to the anticipated transaction. The change in the fair value related to the ineffective portion of the hedge, if any, is immediately recognized in earnings. The amount recorded within accumulated other comprehensive loss is reclassified into earnings in the same period during which the underlying hedged transaction affects earnings. Interest Rate Swap and Cap Agreements – Interest rate swap and cap agreements are used to manage interest rate risk associated with floating-rate borrowings under our credit facility. The interest rate swap and cap agreements utilized by the Company effectively modify the Company’s exposure to interest rate risk by converting a portion of the Company’s floating-rate debt to a fixed rate basis through the expiration date of the interest rate swap and cap agreements, thereby reducing the impact of interest rate changes on future interest expense. These agreements involve the receipt of floating rate amounts in exchange for fixed rate interest payments over the term of the agreements without an exchange of the underlying principal amount. These derivative instruments qualify as effective cash flow hedges under U.S. GAAP. For these cash flow hedges, the effective portion of the gain or loss from the financial instruments was initially reported as a component of accumulated other comprehensive loss in stockholders’ deficit and subsequently reclassified into earnings in the same line as the hedged item in the same period or periods during which the hedged item affected earnings. As the interest rate swap and cap agreements are used to manage interest rate risk, any gains or losses from the derivative instruments that are reclassified into earnings are recognized in interest expense-net in the condensed consolidated statements of income. The following table summarizes the Company's interest rate swap agreements: Aggregate Notional Amount (in millions) Start Date End Date Related Term Loans Conversion of Related Variable Rate Debt to $500 6/29/2018 3/31/2025 Tranche E 5.25% (3.0% plus the 2.25% margin percentage) $750 6/30/2020 6/30/2022 Tranche E 4.75% (2.5% plus the 2.25% margin percentage) $1,500 6/30/2022 3/31/2025 Tranche E 5.35% (3.1% plus the 2.25% margin percentage) $700 3/31/2023 9/30/2025 Tranche F 3.55% (1.3% plus the 2.25% margin percentage) $1,400 6/30/2021 3/31/2023 Tranche F 5.25% (3.0% plus the 2.25% margin percentage) $400 9/30/2017 9/30/2022 Tranche G 4.15% (1.9% plus the 2.25% margin percentage) $900 12/31/2021 6/28/2024 Tranche G 5.35% (3.1% plus the 2.25% margin percentage) $400 9/30/2022 6/28/2024 Tranche G 5.25% (3.0% plus the 2.25% margin percentage) The following table summarizes the Company's interest rate cap agreements: Aggregate Notional Amount (in millions) Start Date End Date Related Term Loans Offsets Variable Rate Debt Attributable to $750 6/30/2020 6/30/2022 Tranche E Three month LIBOR rate of 2.50% $700 3/31/2023 9/30/2025 Tranche F Three month LIBOR rate of 1.25% Certain derivative asset and liability balances are offset where master netting agreements provide for the legal right of setoff. For classification purposes, we record the net fair value of each type of derivative position that is expected to settle in less than one year with each counterparty as a net current asset or liability and each type of long-term position as a net non-current asset or liability. The amounts shown in the table below represent the gross amounts of recognized assets and liabilities, the amounts offset in the condensed consolidated balance sheets and the net amounts of assets and liabilities presented therein (in millions): January 1, 2022 September 30, 2021 Asset Liability Asset Liability Interest rate cap agreements $ 11 $ — $ 8 $ — Interest rate swap agreements — (209) — (280) Net derivatives as classified in the condensed consolidated balance sheets (1) $ 11 $ (209) $ 8 $ (280) (1) Refer to Note 11, “Fair Value Measurements,” for the condensed consolidated balance sheets classification of our interest rate swap and cap agreements. Based on the fair value amounts of the interest rate swap and cap agreements determined as of January 1, 2022, the estimated net amount of existing gains and losses and caplet amortization expected to be reclassified into interest expense-net within the next 12 months is approximately $106.3 million. Foreign Currency Forward Exchange Contracts – The Company transacts business in various foreign currencies, which subjects the Company’s cash flows and earnings to exposure related to changes in foreign currency exchange rates. These exposures arise primarily from purchases or sales of products and services from third parties. Foreign currency forward exchange contracts provide for the purchase or sale of foreign currencies at specified future dates at specified exchange rates, and are used to offset changes in the fair value of certain assets or liabilities or forecasted cash flows resulting from transactions denominated in foreign currencies. At January 1, 2022, the Company had outstanding foreign currency forward exchange contracts to sell U.S. dollars with notional amounts of $97.5 million. The maximum duration of the Company’s foreign currency cash flow hedge contracts at January 1, 2022 is 9 months. These notional values consist of contracts for the Canadian dollar and the European euro and are stated in U.S. dollar equivalents at spot exchange rates at the respective trade dates. Amounts related to foreign currency forward exchange contracts included in accumulated other comprehensive loss in stockholders' deficit are reclassified into net sales when the hedged transaction settles. During the thirteen week period ended January 1, 2022, the losses reclassified on settlements of foreign currency forward exchange contracts designated as cash flow hedges into net sales were less than $1 million. The losses were previously recorded as a component of accumulated other comprehensive loss in stockholders' deficit. As of January 1, 2022, the Company expects to record a net loss of approximately $3.7 million on foreign currency forward exchange contracts designated as cash flow hedges to net sales over the next 12 months.

SEGMENTS

Segment Reporting [Abstract]
SEGMENTS	SEGMENTS The Company’s businesses are organized and managed in three reporting segments: Power & Control, Airframe and Non-aviation. The Power & Control segment includes operations that primarily develop, produce and market systems and components that predominately provide power to or control power of the aircraft utilizing electronic, fluid, power and mechanical motion control technologies. Major product offerings include mechanical/electro-mechanical actuators and controls, ignition systems and engine technology, specialized pumps and valves, power conditioning devices, specialized AC/DC electric motors and generators, batteries and chargers, databus and power controls, advanced sensor products, switches and relay panels, high performance hoists, winches and lifting devices, and cargo loading, handling and delivery systems. Primary customers of this segment are engine and power system and subsystem suppliers, airlines, third party maintenance suppliers, military buying agencies and repair depots. Products are sold in the original equipment and aftermarket market channels. The Airframe segment includes operations that primarily develop, produce and market systems and components that are used in non-power airframe applications utilizing airframe and cabin structure technologies. Major product offerings include engineered latching and locking devices, engineered rods, engineered connectors and elastomer sealing solutions, cockpit security components and systems, specialized and advanced cockpit displays, engineered audio, radio and antenna systems, specialized lavatory components, seat belts and safety restraints, engineered and customized interior surfaces and related components, thermal protection and insulation, lighting and control technology and parachutes. Primary customers of this segment are airframe manufacturers and cabin system suppliers and subsystem suppliers, airlines, third party maintenance suppliers, military buying agencies and repair depots. Products are sold in the original equipment and aftermarket market channels. The Non-aviation segment includes operations that primarily develop, produce and market products for non-aviation markets. Major product offerings include seat belts and safety restraints for ground transportation applications, mechanical/electro-mechanical actuators and controls for space applications, hydraulic/electromechanical actuators and fuel valves for land-based gas turbines, and refueling systems for heavy equipment used in mining, construction and other industries and turbine controls for the energy and oil and gas markets. Primary customers of this segment are off-road vehicle suppliers and subsystem suppliers, child restraint system suppliers, satellite and space system suppliers, manufacturers of heavy equipment used in mining, construction and other industries and turbine original equipment manufacturers, gas pipeline builders and electric utilities. The primary measurement used by management to review and assess the operating performance of each segment is EBITDA As Defined. The Company defines EBITDA As Defined as earnings before interest, taxes, depreciation and amortization plus certain non-operating items recorded as corporate expenses including non-cash compensation charges incurred in connection with the Company’s stock incentive plans, restructuring costs related to the Company's cost reduction measures in response to the COVID-19 pandemic, foreign currency gains and losses, acquisition-integration costs, acquisition and divestiture transaction-related expenses, and refinancing costs. COVID-19 pandemic restructuring costs represent actions taken by the Company to reduce its workforce to align with customer demand, as well as incremental costs related to the pandemic that are not expected to recur once the pandemic has subsided and are clearly separable from normal operations (e.g., additional cleaning and disinfecting of facilities by contractors above and beyond normal requirements, personal protective equipment). Acquisition and divestiture-related costs represent accounting adjustments to inventory associated with acquisitions of businesses and product lines that were charged to cost of sales when the inventory was sold; costs incurred to integrate acquired businesses and product lines into the Company’s operations, facility relocation costs and other acquisition-related costs; transaction-related costs for both acquisitions and divestitures comprising deal fees; legal, financial and tax diligence expenses and valuation costs that are required to be expensed as incurred and other acquisition accounting adjustments. EBITDA As Defined is not a measurement of financial performance under U.S. GAAP. Although the Company uses EBITDA As Defined to assess the performance of its business and for various other purposes, the use of this non-GAAP financial measure as an analytical tool has limitations, and it should not be considered in isolation or as a substitute for analysis of the Company’s results of operations as reported in accordance with U.S. GAAP. The Company’s segments are reported on the same basis used internally for evaluating performance and for allocating resources. The accounting policies for each segment are the same as those described in the summary of significant accounting policies in the Company’s condensed consolidated financial statements. Intersegment sales and transfers are recorded at values based on market prices, which creates intercompany profit on intersegment sales or transfers that is eliminated in consolidation. Intersegment sales were immaterial for the periods presented below. Corporate consists of our corporate offices. Corporate office expenses consist primarily of compensation, benefits, professional services and other administrative costs incurred by the corporate offices. Corporate assets consist primarily of cash and cash equivalents. Corporate expenses and assets reconcile reportable segment data to the consolidated totals. An immaterial amount of corporate expenses are allocated to the operating segments. The following table presents net sales by reportable segment (in millions): Thirteen Week Periods Ended January 1, 2022 January 2, 2021 Net sales to external customers Power & Control Commercial and non-aerospace OEM $ 136 $ 126 Commercial and non-aerospace aftermarket 202 132 Defense 312 343 Total Power & Control 650 601 Airframe Commercial and non-aerospace OEM 143 142 Commercial and non-aerospace aftermarket 164 112 Defense 199 210 Total Airframe 506 464 Total Non-aviation 38 43 Net Sales $ 1,194 $ 1,108 The following table reconciles EBITDA As Defined by segment to consolidated income from continuing operations before income taxes (in millions): Thirteen Week Periods Ended January 1, 2022 January 2, 2021 EBITDA As Defined Power & Control $ 328 $ 304 Airframe 226 177 Non-aviation 14 15 Total segment EBITDA As Defined 568 496 Less: Unallocated corporate expenses 3 22 Total Company EBITDA As Defined 565 474 Depreciation and amortization expense 65 58 Interest expense, net 264 267 Acquisition and divestiture-related costs 5 4 Non-cash stock compensation expense 37 49 COVID-19 pandemic restructuring costs — 21 Other, net 1 22 Income from continuing operations before income taxes $ 193 $ 53 The following table presents total assets by segment (in millions): January 1, 2022 September 30, 2021 Total assets Power & Control $ 6,870 $ 6,980 Airframe 7,459 7,472 Non-aviation 223 229 Corporate 4,690 4,634 $ 19,242 $ 19,315

Leases [Abstract]
LEASES	LEASES The Company leases certain manufacturing facilities, offices, land, equipment and vehicles. Such leases, some of which are noncancellable and, in many cases, include renewals, expire at various dates. Such options to renew are included in the lease term when it is reasonably certain that the option will be exercised. The Company’s lease agreements typically do not contain any significant residual value guarantees or restrictive covenants, and payments within certain lease agreements are adjusted periodically for changes in an index or rate. The Company determines if an arrangement is a lease at inception. Operating lease assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. Lease assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The discount rate implicit within our leases is generally not determinable and therefore we determine the discount rate based on our incremental borrowing rate. The incremental borrowing rate for our leases is determined based on the lease term and the currency in which lease payments are made. The length of a lease term includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise those options. The Company made an accounting policy election to not recognize lease assets or liabilities for leases with a term of 12 months or less. Additionally, when accounting for leases, the Company combines payments for leased assets, related services and other components of a lease. The components of lease expense are as follows (in millions): Thirteen Week Periods Ended Classification January 1, 2022 January 2, 2021 Operating lease cost Cost of Sales or Selling and Administrative Expenses $ 8 $ 7 Finance lease cost Amortization of leased assets Cost of Sales 1 1 Interest on lease liabilities Interest Expense - Net 2 1 Total lease cost $ 11 $ 9 Supplemental cash flow information related to leases is as follows (in millions): Thirteen Week Periods Ended January 1, 2022 January 2, 2021 Cash paid for amounts included in the measurement of lease liabilities: Operating cash outflows from operating leases $ 7 $ 7 Operating cash outflows from finance leases 2 1 Financing cash outflows from finance leases 1 — Lease assets obtained in exchange for new lease obligations: Operating leases $ 2 $ 4 Financing leases 25 19 Supplemental balance sheet information related to leases is as follows (in millions): Classification January 1, 2022 September 30, 2021 Operating Leases Operating lease right-of-use assets Other assets $ 89 $ 94 Current operating lease liabilities Accrued and other current liabilities 19 20 Long-term operating lease liabilities Other non-current liabilities 74 79 Total operating lease liabilities $ 93 $ 99 Finance Leases Finance lease right-of-use assets, net Property, plant and equipment - net $ 129 $ 104 Current finance lease liabilities Accrued and other current liabilities 2 2 Long-term finance lease liabilities Other non-current liabilities 126 98 Total finance lease liabilities $ 128 $ 100 As of January 1, 2022, the Company has the following remaining lease term and weighted average discount rates: Weighted-average remaining lease term Operating leases 6.4 years Finance leases 21.5 years Weighted-average discount rate Operating leases 5.1% Finance leases 7.2% Maturities of lease liabilities at January 1, 2022 are as follows (in millions): Operating Leases Finance Leases 2022 $ 18 $ 9 2023 19 11 2024 16 12 2025 13 12 2026 10 12 Thereafter 43 212 Total future minimum lease payments 119 268 Less: imputed interest 26 140 Present value of lease liabilities reported $ 93 $ 128

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	COMMITMENTS AND CONTINGENCIES During the ordinary course of business, the Company is from time to time threatened with, or may become a party to, legal actions and other proceedings. While the Company is currently involved in certain legal proceedings, it believes the results of these proceedings will not have a material adverse effect on its financial condition, results of operations, or cash flows. DoD OIG Audit – TransDigm’s subsidiaries are periodically subject to pricing reviews and government buying agencies that purchase some of our subsidiaries’ products are periodically subject to audits by the Department of Defense (“DoD”) Office of Inspector General (“OIG”) with respect to prices paid for such products. In 2019, the DoD OIG received a congressional letter requesting a comprehensive review of TransDigm’s contracts with the DoD from January 2017 through June 2019 to identify whether TransDigm earned excess profits. This subsequently resulted in an audit by the DoD OIG in which the objective was to determine whether TransDigm’s business model impacted the DoD’s ability to pay fair and reasonable prices for spare parts . In December 2021, the OIG completed the audit and issued the related audit report. Despite the audit report making clear there was no wrongdoing by TransDigm, its businesses, or the DoD, the report recommended that TransDigm voluntarily refund at least $20.8 million in excess profit on 150 contracts subject to the audit. TransDigm disagrees with many of the implications contained in the report, and objects to the use of arbitrary standards and analysis which render many areas of the report inaccurate and misleading. These include: (1) The report expressly acknowledges that it used arbitrary standards that are not applicable to the audited contracts and warns that its arbitrary standards should not be used in the future. The use of inapplicable standards results in flawed analysis and is misleading; (2) The report ignores significant real costs incurred by the business and contrary to law reports these costs as excess profit; (3) Despite data demonstrating that the DoD paid lower prices compared to the commercial prices for similar parts, the report did not conduct a price analysis and instead implies that the DoD negotiated prices that were too high. No loss contingency related to the voluntary refund request has been recorded as of January 1, 2022 as the Company has concluded that based on the current facts and circumstances, it's uncertain as to whether or not the requested voluntary refund will be made.

Of the approximately $324 million of other intangible assets recognized for the acquisition, approximately $105 million is deductible for tax purposes. The goodwill and intangible assets are deductible over 15 years. (2) Primarily relates to the recording of loss contract reserves associated with acquired ongoing long-term contracts with customers that were incurring negative gross margins as of the date of acquisition. Based on our review of these contracts, we concluded that the terms of certain contracts were unfavorable when compared to market terms as of the acquisition date. The loss contract reserves, totaling $80.6 million, will be released over an estimated three to five year period.

Accounts Receivable, Allowance for Credit Loss	Allowance for Credit Losses – The Company's allowance for credit losses is the allowance for uncollectible accounts. The allowance for uncollectible accounts reduces the trade accounts receivable balance to the estimated net realizable value equal to the amount that is expected to be collected. The Company’s method for developing its allowance for credit losses is based on historical write-off experience, the aging of receivables, an assessment of the creditworthiness of customers, economic conditions and other external market information. All provisions for allowances for uncollectible accounts are included in selling and administrative expenses. As of January 1, 2022 and September 30, 2021, the allowance for uncollectible accounts was $30 million. The allowance for uncollectible accounts is assessed individually at each operating unit by the operating unit’s management team.

[1]	Primarily relates to opening balance sheet adjustments recorded from the acquisition of CAC up to the expiration of the one year measurement period.
[2]	Of the approximately $697 million of goodwill recognized for the acquisition, approximately $65 million is deductible for tax purposes. Of the approximately $324 million of other intangible assets recognized for the acquisition, approximately $105 million is deductible for tax purposes. The goodwill and intangible assets are deductible over 15 years.
