Know all by these presents, that the undersigned hereby constitutes and
appoints each of Jessica Warren, Gabrielle Feuer, Amy Paszt and Adrienne McFaye

     capacity as an officer and/or director of TransDigm Group Incorporated,
     a Delaware corporation (the "Company"), Form ID and Forms 3, 4 and 5 in
     accordance with Section 16(a) of the Securities Exchange Act of 1934 and
     the rules thereunder; and

     2. do and perform any and all acts for and on behalf of the undersigned
     which may be necessary or desirable to complete and execute any such Form
     ID and Form 3, 4 or 5, complete and execute any amendment or amendments
     thereto, and timely file such form with the United States Securities and
     Exchange Commission and any stock exchange or similar authority.

The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
