AD 2024-12-09 Airworthiness Directives; The Boeing Company Airplanes
Models named: 757-200, PF, -200CB, -300 series. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to all The Boeing Company Model 757-200, PF, -200CB, and -300 series airplanes, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as specified by paragraph (h) of this AD: At the applicable times specified in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 757-57A0073 RB, Revision 3, dated May 5, 2023, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 757-57A0073 RB, Revision 3, dated May 5, 2023. Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 757-57A0073, Revision 3, dated May 5, 2023, which is referred to in Boeing Alert Requirements Bulletin 757-57A0073 RB, Revision 3, dated May 5, 2023.
Unsafe condition
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. The FAA is issuing this AD to address cracking in the wing upper skin and forward drag fittings, which could lead to a compromised upper link and reduced structural integrity of the engine strut, and possible separation of a strut and engine from the airplane during flight.
Affected ADs
This AD replaces AD 2022-08-12, Amendment 39-22015 (87 FR 26964, May 6, 2022) (AD 2022-08-12).
