ACTION: Final rule. SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2022-08-12, which applies to all The Boeing Company Model 757 airplanes. AD 2022-08-12 required repetitive inspections for skin cracking and shim migration at the upper link drag fittings, diagonal brace cracking, and fastener looseness; and applicable on-condition actions. This AD was prompted by reports of bolt rotation in the engine drag fitting joint and fastener heads and cracks found in the skin of the fastener holes, a determination that certain drag fittings may be made of alternate materials, which could result in reduced structural integrity of the engine strut, and a determination that additional inspections and revised compliance times are needed. This AD retains the requirements of AD 2022-08-12 with revised compliance times for certain actions and requires adding inspections for existing repairs and applicable on condition actions. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective August 22, 2024.
