What to do
Operators must review aircraft and landing gear maintenance records within 30 days of 15 August 2022, following BAE Systems Service Bulletin ATP-32-109 Revision 1. Bolts with fewer than 5750 landings must be replaced before reaching 6000 landings, while those exceeding 5750 landings must be replaced within 250 landings after 15 August 2022. All replacements must follow the specified service bulletin procedures.
Summary
Civil Aviation Authority Airworthiness Directive G-2022-0015 addresses the inspection and replacement of main landing gear shock absorber bolts on BAe ATP aeroplanes. This directive mandates reviewing maintenance records and replacing bolts based on accumulated landings to prevent structural failure. It applies to all BAe ATP aircraft serial numbers and references BAE Systems Service Bulletin ATP-32-109 Revision 1 for detailed instructions.
What changed
This new Airworthiness Directive introduces mandatory inspections of maintenance records and replacement of main landing gear shock absorber bolts on BAe ATP aircraft. It sets specific landing count thresholds for replacement to mitigate fatigue cracking risks. The directive establishes compliance timelines and references a specific service bulletin for implementation.
Why it matters
This directive is critical for aviation professionals to prevent potential main landing gear structural failures caused by fatigue cracking in shock absorber bolts. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. Failure to comply could result in unsafe landing gear conditions, risking aircraft integrity during landing operations.
