FAA requires new maintenance limits for certain Boeing 757 airplanes with Aviation Partners Boeing winglets
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
This rule requires operators of certain Boeing 757-200 and 757-300 airplanes modified with Aviation Partners Boeing winglets to update their maintenance or inspection programs with new or tighter airworthiness limits. The FAA says the change is needed to catch fatigue cracking in the wing and winglet area before it can threaten the plane’s structural strength. For airlines and other operators, the main task is to revise maintenance programs within 30 days of the rule’s effective date and follow the new inspection timing. The rule also ends some older requirements from a 2020 directive for these aircraft and limits the use of alternative inspection schedules unless the FAA approves them.
