Airworthiness Directive · Amendment 39-21650 · Trailing edge flaps
Gulfstream Aerospace Corporation Airplanes
This AD applies to Gulfstream Aerospace Corporation Model GVII-G500 airplanes, serial numbers 72001 through 72085, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation (Gulfstream) Model GVII-G500 airplanes. This AD results from flap yoke fittings with design features that cause decreased fatigue life. This AD requires replacing the flap inboard and outboard yoke fitting assemblies and establishing a 20,000 flight cycle life limit for the fittings. The FAA is issuing this AD to address the unsafe condition on these products.
(1) Within 24 months after the effective date of this AD or within 500 flight cycles after the effective date of this AD, whichever occurs first, replace each flap yoke fitting assembly by following Sections III.A.2 through III.D of the Modification Instructions in Gulfstream GVII-G500 Aircraft Service Change No. 032, Initial Issue, dated November 20, 2020.
(2) Within 24 months after the effective date of this AD, revise the existing Airworthiness Limitations section of the Instructions for Continued Airworthiness or aircraft inspection program for your airplane by establishing a life limit of 20,000 flight cycles for each flap yoke fitting part number 72P5755095A001, 72P5755096A001, 72P5755097A001, and 72P5755098A001.
Note 1 to paragraph (g)(2): Section 05-10-10 of Gulfstream Aerospace GVII-G500 Aircraft Maintenance Manual Document Number GAC-AC-GVII-G500-AMM-0001, Revision 7, dated December 15, 2020, contains the life limit in paragraph (g)(2) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
