ITEM 7 a.  FINANCIAL STATEMENTS OF BUSINESS ACQUIRED

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors
Federal-Mogul Corporation:

     We have audited the accompanying balance sheets of Federal-Mogul Aviation,
Inc. as of December 31, 2000 and 1999 and the related statements of operations
and cash flows for the years then ended, the period from October 10, 1998
through December 31, 1998 and for the Aviation Division of the Cooper Automotive
Division of Cooper Industries (the Predecessor) for the period from January 1,
1998 through October 9, 1998. These financial statements are the responsibility
of the respective Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Federal-Mogul Aviation, Inc.
at December 31, 2000 and 1999 and the results of its operations and its cash
flows for the years then ended, the period from October 10, 1998 through
December 31, 1998 and for the Predecessor for the period from January 1, 1998
through October 9, 1998, in conformity with accounting principles generally
accepted in the United States.

                          FEDERAL-MOGUL AVIATION, INC.

                          NOTES TO FINANCIAL STATEMENTS

NOTE 1: BASIS OF PRESENTATION

         The accompanying financial statements reflect the assets, liabilities
and operations of Federal-Mogul Aviation, Inc. ("Aviation"). Aviation is a
wholly owned subsidiary of Federal-Mogul Corporation ("Federal-Mogul"). Aviation
was previously an operating unit included in the Cooper Automotive Division of
Cooper Industries, Inc. ("Cooper"). Federal-Mogul purchased the automotive
divisions of Cooper, including Aviation, on October 9, 1998.

         Aviation operates with complete financial and operations staff on a
decentralized basis. Its parent provides certain centralized services for
employee benefits administration, cash management, risk management, legal
services, public relations, domestic tax reporting and internal and external
audit. Its parent bills Aviation for all direct costs incurred on behalf of
Aviation. General corporate, accounting, tax, legal and other administrative
costs that are not directly attributable to the operations of Aviation have been
allocated to Aviation in the accompanying financial statements.

     The accompanying financial statements are presented as if Aviation had
existed as an entity separate from its parent during the period presented and
include the assets, liabilities, revenues and expenses that are directly related
to Aviation's operations. Since the date of Federal-Mogul's acquisition of
Aviation, the financial statements include the push-down of fair value
adjustments to assets and liabilities, including goodwill, other intangible
assets and property, plant and equipment and their related amortization and
depreciation adjustments.

     Because Aviation is fully integrated into its parent's worldwide cash
management system, all of its cash requirements are provided by its parent and
any excess cash generated by Aviation is transferred to its parent. Aviation
participates in Federal-Mogul's accounts receivable securitization program. On
an ongoing basis, Aviation sells certain accounts receivable to Federal-Mogul
Funding Corporation ("FMFC"), a wholly owned subsidiary of Federal-Mogul, which
then sells such receivables, without recourse, to a financial conduit. The
transfers of these receivables are charged to the net parent investment account.
Aviation does not retain any interest in these receivables and the accounts
receivable are sold at carrying value.


NOTE 2: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Use of Estimates: The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

     Inventories: Inventories are carried at cost or, if lower, net realizable
value. Prior to Federal-Mogul's acquisition of Aviation, cost was determined
using the first-in, first-out ("FIFO") method. Subsequent to Federal-Mogul's
acquisition of Aviation, cost was determined using the last-in, first-out
("LIFO") method, which approximated FIFO for all years presented.

     Revenue Recognition: Aviation recognizes revenues and the related customer
incentives when there is evidence of a sales agreement, the delivery of the
goods has occurred, the sales price is fixed or determinable and the ability to
collect the revenue is reasonably assured. Aviation generally records revenue
upon shipment of product to the customer, which coincides with the transfer of
title under standard commercial terms.

     Research and Development Costs: Aviation expenses research and development
costs when incurred. Research and development costs were $1.6 million and $1.9
million for the years ended December 31, 2000 and 1999 and $1.4 million and $0.4
million for the period from January 1, 1998 through October 9, 1998 and October
10, 1998 through December 31, 1998, respectively.

     Property, Plant and Equipment: Property, plant and equipment are stated at
Federal-Mogul's cost. Depreciation is provided over the estimated useful lives
of the related assets using the straight-line method, which in general are
depreciated over the following lives: buildings--10 to 40 years and machinery
and equipment--3 to 20 years.

     Intangible assets are periodically reviewed for impairment indicators. If
impairment indicators exist, an assessment of undiscounted future cash flows
related to assets held for use or fair value for assets held for sale are
evaluated accordingly. Intangible assets are amortized on a straight-line basis
over their estimated useful lives.

     Net Parent Investment: The Net Parent Investment account includes
Aviation's historical earnings, intercompany amounts, income taxes deferred and
payable, postemployment benefit liabilities and other transactions between
Aviation and its parent.

     Fair Value of Financial Instruments: The carrying amounts of certain
financial instruments such as other receivables and accounts payable approximate
their fair value for all years presented.

     Intercompany transactions are principally cash transfers and non-cash
charges between Aviation and its parent.

     Aviation has an inter-company loan with Federal-Mogul in the amount of
$30.5 million, which is included in the net parent investment balance at
December 31, 2000, 1999 and 1998. In 2000, 1999 and 1998 Federal-Mogul charged
interest on this balance based on the stated rate of 6.9%.

     Federal-Mogul has pledged 100% of Aviation's capital stock and also
provided collateral in the form of a pledge of inventories, property, plant and
equipment, real property and intellectual properties to secure certain
outstanding debt of Federal-Mogul. In addition, Aviation has guaranteed fully
and unconditionally, on a joint and several basis, the obligation to pay
principal and interest under Federal-Mogul's Senior Credit Agreements and its
publicly traded registered debt. Such pledges and guarantees have also been made
by certain other subsidiaries of Federal-Mogul.

     Deferred taxes and income taxes payable are a component of the net
investment in parent.

NOTE 5: PENSION PLANS

     In 1998, prior to Federal-Mogul's acquisition of Aviation, the various
pension plans of Aviation were merged into one plan of Cooper. As such, the
related pension liabilities were recorded to net parent investment. This plan
was assumed by Federal-Mogul in its acquisition of the automotive divisions of
Cooper. This plan was required to be fully funded by Cooper prior to the
acquisition by Federal-Mogul. In 2000, Federal-Mogul consolidated all domestic
qualified defined benefit plans into one plan, the Federal Mogul Corporation
Pension Plan.

     The expense charged to Aviation was $0.2 million and $0.2 million for the
years ended December 31, 2000 and 1999 and $0.3 million for the period from
January 1, 1998 through October 8, 1998. There was no expense recorded for the
period from October 9, 1998 through December 31, 1998.

     At December 31, 2000 and 1999, the Federal-Mogul Corporation Pension Plan's
projected benefit obligation was $721.8 million and $345.6 million based on
discount rates of 8% and 7.75%, and the fair value of plan assets were $852.5
million and $327.0 million, respectively.

NOTE 6: CONCENTRATION OF CREDIT RISK AND OTHER

     Aviation grants credit to their customers, which are primarily in the
aerospace industry. Credit risk with respect to trade receivables is generally
diversified due to the large number of entities comprising Aviation's customer
base. Aviation performs periodic credit evaluations of their customers and
generally do not require collateral.

      Aviation operates in a single business segment, manufacturing primarily
engine ignition systems and related parts for the aerospace industry. Aviation
manufactures and distributes these products for use in the aerospace aftermarket
and original equipment segments of the industry. Two distributors accounted for
approximately 25% and 12%, 27% and 10%, and 31% and 11% of net sales for the
years ended December 31, 2000, 1999 and 1998, respectively. No other customer
accounted for 10% or more of revenues in 2000, 1999 or 1998. All of Aviation's
operations are conducted in the United States. Net sales to customers outside
the United States, principally to European customers, were 22%, 20%, and 22% of
the total net sales for the years ended December 31, 2000, 1999 and 1998,
respectively.

NOTE 7: SUBSEQUENT EVENT

      On May 31, 2001, a corporation formed by TransDigm Inc. acquired
substantially all of the assets and assumed certain liabilities of Aviation for
approximately $160.1 million in cash. The purchase price is subject to
adjustment for changes in working capital as defined in the Asset Purchase
Agreement.

FEDERAL-MOGUL AVIATION, INC.

NOTES TO FINANCIAL STATEMENTS
AS OF MARCH 31, 2001 AND DECEMBER 31, 2000
AND FOR THE THIRTEEN WEEK PERIODS ENDED MARCH 31, 2001 AND 2000
- --------------------------------------------------------------------------------

1.    DESCRIPTION OF THE BUSINESS AND BASIS OF PRESENTATION

      The accompanying financial statements reflect the assets, liabilities and
      operations of Federal-Mogul Aviation, Inc. ("Aviation"). Aviation is a
      wholly-owned subsidiary of Federal-Mogul Corporation ("Federal-Mogul").
      Aviation was previously an operating unit included in the Cooper
      Automotive Division of Cooper Industries, Inc. ("Cooper"). Federal-Mogul
      purchased the automotive divisions of Cooper, including Aviation, on
      October 9, 1998.

      Prior to the transaction described in Note 4, Aviation operated with
      complete financial and operations staff on a decentralized basis. Its
      parent provided certain centralized services for employee benefits
      administration, cash management, risk management, legal services, public
      relations, domestic tax reporting and internal and external audit. Its
      parent billed Aviation for all direct costs incurred on behalf of
      Aviation. General corporate, accounting, tax, legal and other
      administrative costs that were not directly attributable to the operations
      of Aviation have been allocated to Aviation in the accompanying financial
      statements.

      The accompanying financial statements are presented as if Aviation had
      existed as an entity separate from its parent during the period presented
      and include the assets, liabilities, revenues and expenses that are
      directly related to Aviation's operations. Since the date of
      Federal-Mogul's acquisition of Aviation, the financial statements include
      the push-down of fair value adjustments to assets and liabilities,
      including goodwill, other intangible assets and property, plant and
      equipment and their related amortization and depreciation of adjustments.

2.    UNAUDITED FINANCIAL INFORMATION

      The unaudited financial statements included herein reflect all adjustments
      (consisting solely of normal recurring adjustments) that are, in the
      opinion of management, necessary for a fair presentation of Aviation's
      financial position and results of operations and cash flows for the
      interim periods presented in accordance with accounting principles
      generally accepted in the United States of America and with instructions
      to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the financial
      statements do not include all the information and footnotes required under
      accounting principles generally accepted in the United States of
      America for complete financial statements. The results of operations for
      the thirteen week period ended March 31, 2001 are not necessarily
      indicative of the results to be expected for the full year. For further
      information, refer to the consolidated financial statements and footnotes
      included in this document for the year ended December 31, 2000.

3.    INVENTORIES

      Inventories are carried at cost, or if lower, net realizable value. Cost
      of inventories is determined by the first-in, first-out (FIFO) method.
      Inventories consist of the following (in thousands):

FEDERAL-MOGUL AVIATION, INC.

NOTES TO FINANCIAL STATEMENTS
AS OF MARCH 31, 2001 AND DECEMBER 31, 2000
AND FOR THE THIRTEEN WEEK PERIODS ENDED MARCH 31, 2001 AND 2000
- --------------------------------------------------------------------------------

4.    SUBSEQUENT EVENT

      On May 31, 2001, a corporation formed by TransDigm Inc. acquired
      substantially all of the assets and assumed certain liabilities of
      Aviation for approximately $160.1 million in cash. The purchase price is
      subject to adjustment for changes in working capital as defined in the
      Asset Purchase Agreement.

ITEM 7b. UNAUDITED PRO FORMA FINANCIAL INFORMATION

The following pro forma consolidated financial information of TransDigm Holdings
is based on the historical consolidated financial statements and the
accompanying notes of TransDigm Holdings and the historical financial statements
and the accompanying notes of Federal-Mogul Aviation, Inc. ("Aviation"). The pro
forma consolidated statements of operations give effect to the Acquisition as if
it had been consummated at the beginning of each respective period. The pro
forma consolidated balance sheet gives effect to the Acquisition and the related
borrowings under the Credit Agreement as if they had occurred as of the balance
sheet date. The adjustments necessary to fairly present this pro forma
consolidated financial information have been made based on available information
and, in the opinion of management, are reasonable and are described in the
accompanying notes. The pro forma consolidated financial information should not
be considered indicative of actual results that would have been achieved had the
Acquisition been consummated on the respective dates indicated and do not
purport to indicate results of operations for any future period.

The Acquisition has been accounted for as a purchase. The purchase price
consideration of $160.1 million in cash and $1.8 million of costs associated
with the Acquisition was funded through: (1) $147.6 million of new borrowings
under the Credit Agreement and (2) $14.3 million received (net of fees of $.7
million) from the issuance of $15 million of TransDigm Holdings' 16% Cumulative
Redeemable Preferred Stock and warrants to purchase 1,381.87 shares of TransDigm
Holdings' common stock. TransDigm also borrowed an additional $15 million under
the Credit Agreement to pay $5 million of debt issuance costs and provide $10
million of working capital for future operations. The purchase price has been
allocated to the assets acquired and liabilities assumed based on a preliminary
analysis of their fair values, which is subject to adjustment. The purchase
price is subject to adjustment for changes in working capital as of the closing
of the Acquisition.

            incurred in connection with the Acquisition (at a weighted average
            rate of 7.54%) along with the amortization of the related,
            additional debt issuance costs. A 0.250% increase or decrease in the
            weighted average interest rate applicable to the additional
            indebtedness incurred in connection with the Acquisition would
            change the pro forma interest expense and net income by $406 and
            $244, respectively, for the year ended September 30, 2000.

      (d)   Represents the elimination of intercompany interest expense charged
            by Federal-Mogul, which was terminated as a result of the
            Acquisition.

      (e)   Represents the tax effect of pro forma adjustments to income before
            income taxes and is based on the estimated, applicable statutory tax
            rates.

(1)   Represents the adjustments resulting from the Acquisition that are
      necessary to determine TransDigm Holdings' pro forma consolidated balance
      sheet:

            funds for future operations.

      (b)   Represents the excess of the fair value of Aviation's inventory over
            its carrying value. As the inventory is sold, this adjustment will
            be charged to cost of sales. TransDigm expects this inventory to be
            sold over a three month period.

      (c)   Represents the writeoff of Aviation's perishable tooling and
            supplies to conform to TransDigm Holdings' accounting policy of
            expensing such items when purchased.

      (d)   Represents the allocation of the purchase price to intangible
            assets, principally goodwill.

      (e)   Represents the costs incurred to obtain the additional borrowings
            described in (f).

      (f)   Represents additional borrowings made under the Credit Agreement to
            finance the purchase price and the direct costs of the Acquisition.

      (g)   Represents the proceeds from the preferred stock and related
            warrants issued to provide financing for the Acquisition, net of the
            costs of issuance.

      (h)   Eliminates the net parent investment in Aviation.
