What to do
Affected operators must revise the airworthiness limitations section or inspection program within 12 months of the AD's effective date, February 28, 2023, to establish the 20,000 flight cycle life limit for MLG trunnion pin P/N 1159SCL566-17. They should coordinate with maintenance and engineering teams to update documentation and ensure inspections and replacements comply with the new life limit. Requests for alternative methods of compliance can be submitted to the FAA's Atlanta ACO Branch as specified.
Summary
The Federal Aviation Administration's Final Rule titled 'Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes' establishes a new airworthiness directive (AD 2023-02-02) applicable to all Gulfstream Model GV and GV-SP airplanes, including marketing designations G500, G550, and G500-5000. This directive addresses the omission of a life limit for the main landing gear (MLG) trunnion pin part number 1159SCL566-17 in the airworthiness limitations section of the maintenance manual.
What changed
This new AD introduces a mandatory revision to the airworthiness limitations section or inspection program to incorporate a life limit of 20,000 flight cycles for the affected MLG trunnion pin. It requires operators to update their maintenance manuals accordingly to prevent the trunnion pin from remaining in service beyond this limit. The directive does not supersede any previous ADs and imposes no additional economic burden beyond the manual revision.
Why it matters
For aviation professionals, this AD is critical to ensure continued airworthiness and safety of Gulfstream GV and GV-SP aircraft by preventing potential failure of the main landing gear trunnion pin due to exceeding its life limit. Operators and maintenance organizations must comply to avoid risks of landing gear failure that could lead to runway excursions, thereby protecting passengers, crew, and aircraft integrity. Compliance ensures adherence to FAA safety regulations and avoids regulatory penalties.
