Airworthiness Directive · Amendment 39-21860 · Landing gear system
Gulfstream Aerospace Corporation Airplanes
This AD applies to Gulfstream Aerospace Corporation Model GV and GV-SP airplanes, all serial numbers, certificated in any category.
Note 1 to paragraph (c): Model GV-SP airplanes are also referred to by the marketing designations G500, G550, and G500-5000.
The FAA is adopting a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation (Gulfstream) Model GV and GV-SP airplanes. This AD was prompted by the omission of a life limit in the airworthiness limitations section (ALS) of the maintenance manual for a certain main landing gear (MLG) trunnion pin. This AD requires revising the ALS of your existing instructions for continued airworthiness (ICA) or inspection program for the airplane to establish a life limit of 20,000 flight cycles for the affected MLG trunnion pin. The FAA is issuing this AD to address the unsafe condition on these products.
Within 12 months after the effective date of this AD, revise the existing ALS 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 MLG trunnion pin part number 1159SCL566-15.
Note 2 to paragraph (g): Table 5 in Section 05-10-10 of the following aircraft maintenance manuals contains the life limit in paragraph (g) of this AD: Gulfstream GV Aircraft Maintenance Manual, Revision 53, dated March 15, 2021; Gulfstream G550 Aircraft Maintenance Manual, Revision 34, dated March 15, 2021; or Gulfstream G500-5000 Aircraft Maintenance Manual, Revision 34, dated March 15, 2021.
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.
