Models named: 767-200, -300, -300F, -400ER 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 767-200, -300, -300F, and -400ER series airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin 767-53A0251, Revision 1, dated March 7, 2017. (2) Installation of Supplemental Type Certificate (STC) ST01920SE ( rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/59027F43B9A7486E86257B1D006591EE?OpenDocument&Highlight=st01920se ) does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST01920SE 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: At the applicable times specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 767-53A0251, Revision 1, dated March 7, 2017, do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of Boeing Alert Service Bulletin 767-53A0251, Revision 1, dated March 7, 2017.

Unsafe condition

This AD was prompted by reports indicating that certain fasteners were not installed in the stringer 37 (S-37L and S-37R) lap splice between body stations 428 and 431 on certain airplanes. We are issuing this AD to detect and correct missing fasteners, which could result in cracks in the fuselage skin that could adversely affect the structural integrity of the airplane.

Affected ADs

This AD replaces AD 2015-19-12, Amendment 39-18274 (80 FR 58346, September 29, 2015) (“AD 2015-19-12”).
