Models named: 757-200, -200CB, -300 series. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

(1) This AD applies to The Boeing Company Model 757-200, -200CB, and -300 series airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin 757-53A0100, Revision 1, dated September 14, 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.

Compliance

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

Required actions

Except as required by paragraph (h) of this AD: Do all applicable actions identified as required for compliance (RC) in, and in accordance with, the Accomplishment Instructions of Boeing Alert Service Bulletin 757-53A0100, Revision 1, dated September 14, 2017. Do the actions at the applicable times specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 757-53A0100, Revision 1, dated September 14, 2017.

Unsafe condition

This AD was prompted by a report of fatigue cracking found in the fuselage frame web at station (STA) 1681. We are issuing this AD to detect and correct cracking of the fuselage frame at STA 1681, which could result in reduced structural integrity of the airplane.

Affected ADs

None.
