Airworthiness Directive · Amendment 39-19228 · Fuselage
The Boeing Company Airplanes
(1) This AD applies to The Boeing Company Model 757-200 series airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin 757-53A0012, Revision 1, dated January 25, 2017.
(2) Installation of Supplemental Type Certificate (STC) ST01518SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/312bc296830a925c86257c85006d1b1f/$FILE/ST01518SE.pdf) does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST01518SE is installed, a “change in product” alternative method of compliance (AMOC) approval request is not necessary to comply with the requirements of 14 CFR 39.17.
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 757-200 series airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the side panel-to-frame attachments and frames of the aft cargo compartment are subject to widespread fatigue damage (WFD). This AD requires an inspection of the side panel-to-frame attachments and frames to verify that certain modifications have been done, and applicable on-condition actions. We are issuing this AD to address the unsafe condition on these products.
Except as required by paragraph (h) of this AD: At the applicable times specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 757-53A0012, Revision 1, dated January 25, 2017, do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of Boeing Alert Service Bulletin 757-53A0012, Revision 1, dated January 25, 2017.
(1) For purposes of determining compliance with the requirements of this AD: Where Boeing Alert Service Bulletin 757-53A0012, Revision 1, dated January 25, 2017, uses the phrase “the Revision 1 date of this service bulletin,” this AD requires using “the effective date of this AD.”
(2) Where Boeing Alert Service Bulletin 757-53A0012, Revision 1, dated January 25, 2017, specifies contacting Boeing, and specifies that action as RC: This AD requires repair using a method approved in accordance with the procedures specified in paragraph (j) of this AD.
Accomplishment of a modification in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 757-53A0012, Revision 1, dated January 25, 2017, terminates the inspections required by paragraph (g) of this AD at the modified location only.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
