Airworthiness Directive · Amendment 39-22508 · Flight controls
Gulfstream Aerospace Corporation Airplanes
This AD applies to Gulfstream Aerospace Corporation Model GVII-G600 airplanes, certificated in any category, serial numbers 73001 through 73051 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation Model GVII-G600 airplanes. This AD was prompted by an addition of a life limit in the Airworthiness Limitations Section (ALS) for GVII-G600 flap yokes. The life limit for the GVII-G600 flap yokes was informed by a GVII-G500 flap yoke failure that occurred during flight testing and, ultimately, resulted in additional test and analysis to establish more accurate life limits reflective of each model's design features and stress levels. The FAA is issuing this AD to require revising the existing ALS to prevent the GVII-G600 inboard flap yoke from remaining in service beyond its life limit. The FAA is issuing this AD to address the unsafe condition on these products.
Within 30 days after the effective date of this AD, revise the existing ALS of the Instructions for Continued Airworthiness (ICA) or inspection program for your airplane by establishing a life limit of 4,000 flight cycles for the left-hand part number (P/N) 73P5755033M005 and right-hand P/N 73P5755033M006 inboard flap yoke fittings.
Note 1 to paragraph (g): The life limit in paragraph (g) of this AD is contained in table 2 in Section 05-10-10 of Gulfstream GVII-G600 Aircraft Maintenance Manual, Revision 9, dated November 15, 2022.
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.
