Applicability*9

This AD applies to The Boeing Company Model 757-200, -200CB, and -300 series airplanes, certificated in any category, as identified in Boeing Alert Requirements Bulletin 757-53A0123 RB, dated March 13, 2024.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

(1) For all airplanes except those identified in paragraph (g)(2) of this AD: Except as specified by paragraph (h) of this AD: At the applicable times specified in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 757-53A0123 RB, dated March 13, 2024, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 757-53A0123 RB, dated March 13, 2024. Note 1 to paragraph (g)(1): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 757-53A0123, dated March 13, 2024, which is referred to in Boeing Alert Requirements Bulletin 757-53A0123 RB, dated March 13, 2024. (2) For airplanes identified in Aviation Partners Boeing Alert Service Bulletin AP757-53-006, dated May 7, 2024: Except as specified in paragraph (h) of this AD, at the applicable times specified in paragraph 1.E., “Compliance,” of Aviation Partners Boeing Alert Service Bulletin AP757-53-006, dated May 7, 2024, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 757-53A0123 RB, dated March 13, 2024.

Unsafe condition

This AD was prompted by a report of cracking found in new locations at body station (STA) 1640 during frame segment replacement repairs, including in the web at the K-hole between stringers S-9 and S-10, in the outer chord above the lower hinge intercostal, and in the inner chord and web between stringers S-10 and S-19. The FAA is issuing this AD to address undetected cracks in the fuselage frame at STA 1640, which could affect a principal structural element's ability to sustain limit load. The unsafe condition, if not addressed, could result in reduced structural integrity of the airplane.

Affected ADs

None.
