Models named: 767-200, -300, -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, and -400ER series airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin 767-53A0260, dated August 26, 2014. (2) Installation of Supplemental Type Certificate (STC) ST01920SE ( http://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

At the applicable time specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 767-53A0260, dated August 26, 2014, except as required by paragraph (i) of this AD: Do a detailed inspection and a surface high frequency eddy current (HFEC) inspection at section 41, stringer S-2R skin lap splice from body station (STA) 368 to STA 434, for any cracking, and do all applicable corrective actions, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 767-53A0260, dated August 26, 2014. Do all applicable corrective actions before further flight. Repeat the inspections thereafter at the applicable times specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 767-53A0260, dated August 26, 2014. If any existing external repair is found in the inspection area, then the inspections in Part 1 of the Accomplishment Instructions of Boeing Alert Service Bulletin 767-53A0260, dated August 26, 2014, are not required in the area hidden by the repair, provided that the repair was previously approved by the Manager, Seattle Aircraft Certification Office (ACO), or by the Authorized Representative of the Boeing Commercial Airplanes Organization Designation Authorization (ODA), or installed as specified in Part 2 of the Accomplishment Instructions of Boeing Alert Service Bulletin 767-53A0260, dated August 26, 2014. Inspections in Part 1 of the Accomplishment Instructions of Boeing Alert Service Bulletin 767-53A0260, dated August 26, 2014, remain applicable in areas not hidden by the repair.

Unsafe condition

This AD was prompted by an evaluation by the design approval holder indicating that the skin lap splice is subject to widespread fatigue damage. We are issuing this AD to detect and correct fatigue cracking of this skin lap splice, which could grow and result in possible rapid decompression and reduced structural integrity of the airplane.

Affected ADs

None.
