Business Combinations [Abstract]
ACQUISITIONS AND DIVESTITURES	ACQUISITIONS AND DIVESTITURES Acquisitions DART Aerospace – On March 14, 2022, the Company entered into a definitive agreement to acquire DART Aerospace (“DART”) for a total purchase price of $360 million. The acquisition, which is expected to close during the second half of fiscal 2022, is subject to regulatory approvals and customary closing conditions and will be financed through existing cash on hand. DART operates from four primary facilities (Hawkesbury, Ontario, Canada; Portland, Oregon; Fort Collins, Colorado and Chihuahua, Mexico) and is a leading provider of highly engineered, unique helicopter mission equipment solutions that predominantly service civilian aircraft. The products are primarily proprietary with significant aftermarket content. 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 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. The final allocation of the fair value of assets acquired and liabilities assumed in the CAC acquisition as of the acquisition dates, as well as measurement period adjustments recorded within the permissible one year measurement period, 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. The CAC and DART acquisitions strengthen and expand 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 / to be paid reflect 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 businesses, 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. 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 (“OpenGate”) for approximately $200 million in cash. During the second quarter of fiscal 2021, the Company determined ScioTeq and TREALITY met the criteria to be classified as held for sale. 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. 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.

Accounting Standards Update and Change in Accounting Principle [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTSIn 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 evaluating the impact of reference rate reform on our existing Credit Agreement and our interest rate swap and cap agreements. To the extent that, prior to December 31, 2022, the Company enters into any transactions for which the optional practical expedients permissible under ASC 848 are applied, the adoption of this standard is not expected to have a material impact on the Company's condensed consolidated financial statements and disclosures.

REVENUE RECOGNITION

REVENUE RECOGNITION	Apr. 02, 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): April 2, 2022 September 30, 2021 Contract assets, current (1) $ 96 $ 72 Contract assets, non-current (2) 1 2 Total contract assets 97 74 Contract liabilities, current (3) 36 27 Contract liabilities, non-current (4) 8 5 Total contract liabilities 44 32 Net contract assets $ 53 $ 42 (1) Included in prepaid expenses and other on the condensed consolidated balance sheets.

(4) Included in other non-current liabilities on the condensed consolidated balance sheets. For the thirteen and twenty-six week periods ended April 2, 2022, the revenue recognized that was previously included in contract liabilities was not material. Refer to Note 14, “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 April 2, 2022 and September 30, 2021, the allowance for uncollectible accounts was $33 million and $30 million, respectively. 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 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 April 2, 2022, the borrowings available under the revolving commitments were $774.7 million. The Company capitalized $0.2 million representing debt issuance costs associated with Amendment No. 9 during the twenty-six week period ended April 2, 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 April 2, 2022 and September 30, 2021, the outstanding balance of these advances was $28 million and $29 million, respectively. Obligations under Finance Leases – The Company leases certain buildings and equipment under finance leases. The present value of the minimum finance lease payments, net of the current portion, represents a balance of $149 million and $100 million at April 2, 2022 and September 30, 2021, respectively. The increase in the current fiscal year is attributable to certain lease renewals and amendments qualifying as lease modifications resulting in a change in classification from an operating lease to a finance lease. Refer to Note 17, “Leases,” for further disclosure of the Company's lease obligations.

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 April 2, 2022 and April 3, 2021, the effective income tax rate was 23.5% and 19.2%, respectively. During the twenty-six week periods ended April 2, 2022 and April 3, 2021, the effective income tax rate was 20.1% and 15.3%, respectively. The Company’s higher effective tax rate for the thirteen week period ended April 2, 2022 is primarily due to a decrease in the impact of the discrete tax benefit associated with share-based payments on the effective tax rate relative to comparable prior-year periods. The reduced impact of the discrete tax benefit was the result of an increase in income from continuing operations before income taxes for the same period. The Company’s effective income tax rate for the twenty-six week period ended April 2, 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 through the first half of fiscal 2022, partially offset by an increase in the Company’s net interest deduction limitation pursuant to IRC Section 163(j). 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, and in Germany for fiscal years 2014 through 2017. In addition, the Company is subject to state income tax examinations for fiscal years 2015 and later. Unrecognized tax benefits at April 2, 2022 and September 30, 2021, the recognition of which would have an impact on the effective tax rate for each fiscal year, amounted to $18.6 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 twenty-six week periods ended April 2, 2022 and April 3, 2021. As of April 2, 2022 and September 30, 2021, the Company accrued $5.0 million and $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 MEASUREMENTS	Apr. 02, 2022
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): April 2, 2022 September 30, 2021 Level Carrying Fair Value Carrying Fair Value Assets: Cash and cash equivalents 1 $ 4,216 $ 4,216 $ 4,787 $ 4,787 Interest rate swap agreements (1) 2 37 37 — — Interest rate cap agreements (1) 2 32 32 8 8 Liabilities: Interest rate swap agreements (2) 2 46 46 100 100 Interest rate swap agreements (3) 2 — — 180 180 Foreign currency forward exchange contracts (2) 2 3 3 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 7,286 7,201 7,318 7,268 Revolving credit facility (4) 2 — — 200 200 2025 Secured Notes (4) 1 1,093 1,145 1,093 1,170 6.375% 2026 Notes (4) 1 946 955 945 981 6.875% 2026 Notes (4) 1 495 509 494 527 2026 Secured Notes (4) 1 4,363 4,505 4,359 4,593 7.50% 2027 Notes (4) 1 546 567 546 578 5.50% 2027 Notes (4) 1 2,633 2,617 2,632 2,730 4.625% 2029 Notes (4) 1 1,190 1,119 1,190 1,196 4.875% 2029 Notes (4) 1 744 701 743 751 Government refundable advances 2 28 28 29 29 Finance lease obligations 2 149 149 100 100 (1) Included in other assets 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 10, “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 April 2, 2022 and September 30, 2021.

DERIVATIVES AND HEDGING ACTIVITIES	6 Months Ended
DERIVATIVES AND HEDGING ACTIVITIES	Apr. 02, 2022
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): April 2, 2022 September 30, 2021 Asset Liability Asset Liability Interest rate cap agreements $ 32 $ — $ 8 $ — Interest rate swap agreements 37 (47) — (280) Net derivatives as classified in the condensed consolidated balance sheets (1) $ 69 $ (47) $ 8 $ (280) (1) Refer to Note 12, “Fair Value Measurements,” for the condensed consolidated balance sheets classification of our interest rate swap and cap agreements. The change in the fair value of the interest rate swap and cap agreements is attributable to the upward trend in LIBOR during the first half of fiscal 2022. Based on the fair value amounts of the interest rate swap and cap agreements determined as of April 2, 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 $46.2 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 April 2, 2022, the Company has outstanding foreign currency forward exchange contracts to sell U.S. dollars with notional amounts of $64.1 million. The maximum duration of the Company’s foreign currency cash flow hedge contracts at April 2, 2022 is 6 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 twenty-six week period ended April 2, 2022, the losses reclassified on settlements of foreign currency forward exchange contracts designated as cash flow hedges into net sales was approximately $2.6 million. The losses were previously recorded as a component of accumulated other comprehensive loss in stockholders' deficit. As of April 2, 2022, the Company expects to record a net loss of approximately $2.9 million on foreign currency forward exchange contracts designated as cash flow hedges to net sales over the next 12 months.

SEGMENTS	Apr. 02, 2022
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 Twenty-Six Week Periods Ended April 2, 2022 April 3, 2021 April 2, 2022 April 3, 2021 Net sales to external customers Power & Control Commercial and non-aerospace OEM $ 153 $ 127 $ 289 $ 253 Commercial and non-aerospace aftermarket 202 148 404 280 Defense 353 366 665 709 Total Power & Control 708 641 1,358 1,242 Airframe Commercial and non-aerospace OEM 177 141 320 283 Commercial and non-aerospace aftermarket 184 129 348 241 Defense 218 243 417 453 Total Airframe 579 513 1,085 977 Total Non-aviation 40 40 78 82 Net Sales $ 1,327 $ 1,194 $ 2,521 $ 2,301 The following table reconciles EBITDA As Defined by segment to consolidated income from continuing operations before income taxes (in millions): Thirteen Week Periods Ended Twenty-Six Week Periods Ended April 2, 2022 April 3, 2021 April 2, 2022 April 3, 2021 EBITDA As Defined Power & Control $ 374 $ 309 $ 703 $ 613 Airframe 273 208 499 385 Non-aviation 14 16 28 31 Total segment EBITDA As Defined 661 533 1,230 1,029 Less: Unallocated corporate expenses 28 14 32 36 Total Company EBITDA As Defined 633 519 1,198 993 Depreciation and amortization expense 62 66 127 124 Interest expense, net 266 268 530 535 Acquisition and divestiture transaction-related expenses and adjustments 3 15 8 19 Non-cash stock compensation expense 42 21 79 70 Refinancing costs — 24 — 24 COVID-19 pandemic restructuring costs — 18 — 39 Other, net — (23) 1 (1) Income from continuing operations before income taxes $ 260 $ 130 $ 453 $ 183 The following table presents total assets by segment (in millions): April 2, 2022 September 30, 2021 Total assets Power & Control $ 6,928 $ 6,980 Airframe 7,559 7,472 Non-aviation 230 229 Corporate 4,124 4,634 $ 18,841 $ 19,315

LEASES

LEASES	Apr. 02, 2022
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 Twenty-Six Week Periods Ended Classification April 2, 2022 April 3, 2021 April 2, 2022 April 3, 2021 Operating lease cost Cost of sales or selling and administrative expenses $ 4 $ 7 $ 12 $ 14 Finance lease cost Amortization of leased assets Cost of sales 2 1 3 2 Interest on lease liabilities Interest expense - net 2 2 4 3 Total lease cost $ 8 $ 10 $ 19 $ 19 Supplemental cash flow information related to leases is as follows (in millions): Twenty-Six Week Periods Ended April 2, 2022 April 3, 2021 Cash paid for amounts included in the measurement of lease liabilities: Operating cash outflows from operating leases $ 12 $ 14 Operating cash outflows from finance leases 4 2 Financing cash outflows from finance leases 1 1 Lease assets obtained in exchange for new lease obligations: Operating leases $ 8 $ 38 Financing leases 33 25 Supplemental balance sheet information related to leases is as follows (in millions): Classification April 2, 2022 September 30, 2021 Operating Leases Operating lease right-of-use assets Other assets $ 88 $ 94 Current operating lease liabilities Accrued and other current liabilities 18 20 Long-term operating lease liabilities Other non-current liabilities 74 79 Total operating lease liabilities $ 92 $ 99 Finance Leases Finance lease right-of-use assets, net Property, plant and equipment - net $ 135 $ 104 Current finance lease liabilities Current portion of long-term debt 5 2 Long-term finance lease liabilities Long-term debt 144 98 Total finance lease liabilities $ 149 $ 100 As of April 2, 2022, the Company has the following remaining lease term and weighted average discount rates: Weighted-average remaining lease term Operating leases 6.5 years Finance leases 20.6 years Weighted-average discount rate Operating leases 5.2% Finance leases 7.1% Maturities of lease liabilities at April 2, 2022 are as follows (in millions): Operating Leases Finance Leases 2022 $ 11 $ 6 2023 19 15 2024 16 13 2025 14 13 2026 11 13 Thereafter 47 242 Total future minimum lease payments 118 302 Less: imputed interest 26 153 Present value of lease liabilities reported $ 92 $ 149

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	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 were too high. No loss contingency related to the voluntary refund request has been recorded as of April 2, 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 April 2, 2022 and September 30, 2021, the allowance for uncollectible accounts was $33 million and $30 million, respectively. The allowance for uncollectible accounts is assessed individually at each operating unit by the operating unit’s management team.
