Airworthiness Directive · Amendment 39-19183 · Fuselage
The Boeing Company Airplanes
(1) This AD applies to all The Boeing Company Model 757-300 series airplanes, certificated in any category.
(2) Installation of Supplemental Type Certificate (STC) ST01518SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgSTC.nsf/0/38b606833bbd98b386257faa00602538/$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 all The Boeing Company Model 757-300 series airplanes. This AD was prompted by reports of scribe line damage on fuselage skin. This AD requires detailed inspections of fuselage skin for the presence of scribe lines, and applicable on-condition actions. We are issuing this AD to address the unsafe condition on these products.
Except as provided by paragraph (h) of this AD: At the applicable times specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 757-53A0107, dated July 20, 2017, do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of Boeing Alert Service Bulletin 757-53A0107, dated July 20, 2017.
(1) For purposes of determining compliance with the requirements of this AD, the phrase “the effective date of this AD” may be substituted for “the original issue date of this service bulletin,” as specified in Boeing Alert Service Bulletin 757-53A0107, dated July 20, 2017.
(2) Where Boeing Alert Service Bulletin 757-53A0107, dated July 20, 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 (i) of this AD.
(3) For purposes of determining compliance with the requirements of this AD, the phrase “FAA-approved repair” may be substituted for “approved repair,” as specified in Boeing Alert Service Bulletin 757-53A0107, dated July 20, 2017.
