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 Service Bulletin 767-32A0227, Revision 1, dated September 13, 2012. (2) Installation of Supplemental Type Certificate (STC) ST01920SE ( http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/082838ee177dbf62862576a4005cdfc0/$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.

Compliance

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

Required actions

At the applicable times specified in paragraph 1.E., “Compliance,” of Boeing Service Bulletin 767-32A0227, Revision 1, dated September 13, 2012, except as provided by paragraph (j) of this AD, revise the maintenance program to incorporate the specified maintenance review board (MRB) item, in accordance with Part 1 of the Accomplishment Instructions of Boeing Service Bulletin 767-32A0227, Revision 1, dated September 13, 2012.

Unsafe condition

This AD was prompted by reports of cracks and heat damage found on pivot joint components found during main landing gear (MLG) overhaul. We are issuing this AD to detect and correct heat damage and cracks in the pivot pin, truck beam lugs, and inner cylinder lugs, which could result in fracture of the pivot joint components and consequent MLG collapse.

Affected ADs

AD 2006-07-14, Amendment 39-14541 (71 FR 17691, April 7, 2006), is affected by this AD.
