What to do
Operators of Boeing 757-200, PF, -200CB, and -300 series airplanes must comply with the inspection and repair actions specified in Boeing Alert Requirements Bulletin 757-57A0073 RB, Revision 3, dated May 5, 2023, by August 22, 2024. They should reference the corrected AD number 2024-12-09 in all compliance documentation and coordinate with the FAA or Boeing for any alternative methods of compliance or repair instructions as needed.
Summary
The Correction to Airworthiness Directive 2024-12-09 issued by the Federal Aviation Administration (FAA) addresses all Boeing Company Model 757 airplanes. This correction fixes an incorrect AD number referenced in the original final rule related to inspections of the wing upper skin and drag fittings to detect cracks, loose fasteners, and shim migration. The directive ensures continued airworthiness by mandating inspections and on-condition repairs to maintain structural integrity of the engine strut attachment.
What changed
This document corrects the previously published AD by updating the incorrect AD number from 'AD 2023-12-09' to the correct 'AD 2024-12-09'. No other changes to the inspection requirements, compliance times, or procedures were made. The correction confirms the AD as an amendment to 14 CFR 39.13 with an effective date of August 22, 2024.
Why it matters
Accurate referencing of the AD number is critical for regulatory compliance and record-keeping by operators and maintenance organizations. This correction prevents confusion and ensures that affected parties apply the correct directive for inspections and repairs on Boeing 757 wing structures. Proper compliance helps avoid structural failures that could lead to engine strut separation during flight, enhancing flight safety.
