Airworthiness Directive · Amendment 39-18274 · Fuselage
The Boeing Company Airplanes
Superseded. A later AD replaced this one: AD 2018-07-18. Comply with the one in force.
(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, dated August 7, 2013.
(2) Installation of Supplemental Type Certificate (STC) [ST01920SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/59027f43b9a7486e86257b1d00659v1ee/$FILE/ST01920SE.pdf) 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.
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767 airplanes. This AD was prompted by reports that six fasteners may not have been installed in the left and right stringer 37 (S-37) between body stations (BS) 428 and 431 lap splices on certain airplanes. This AD requires a general visual inspection of S-37 lap splices for missing fasteners, and all applicable related investigative and corrective actions. 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.
Except as provided by paragraph (h)(2) of this AD, at the applicable time specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 767-53A0251, dated August 7, 2013: Do an external general visual inspection of the S-37 lap splice for missing fasteners, and do all applicable related investigative and corrective actions, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 767-53A0251, dated August 7, 2013, except as provided by paragraph (h)(1) of this AD. Do all applicable related investigative and corrective actions before further flight.
(1) Although Boeing Alert Service Bulletin 767-53A0251, dated August 7, 2013, specifies to contact Boeing for repair instructions, and specifies that action as “RC” (Required for Compliance), this AD requires repair before further flight using a method approved in accordance with the procedures specified in paragraph (i)(1) of this AD.
(2) Where Paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 767-53A0251, dated August 7, 2013, specifies a compliance time “after the original issue date of this service bulletin,” this AD requires compliance within the specified compliance time after the effective date of this AD.
