AD 2014-08-11 Airworthiness Directives; the Boeing Company Airplanes
Models named: 737-600, -700, -700C, -800, -900 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 737-600, -700, -700C, -800 and -900 series airplanes, certificated in any category; as identified in Boeing Special Attention Service Bulletin 737-32-1402, Revision 1, dated February 7, 2013. (2) Installation of Supplemental Type Certificate (STC) ST00830SE ( http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/408E012E008616A7862578880060456C?OpenDocument&Highlight=st00830se ) does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST00830SE 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 compliance time specified in paragraph 1.E., “Compliance,” of Boeing Special Attention Service Bulletin 737-32-1402, Revision 1, dated February 7, 2013, except as required by paragraph (j) of this AD: Lubricate the left and right MLG forward trunnion pins, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-32-1402, Revision 1, dated February 7, 2013. Repeat the lubrication thereafter at the applicable time specified in paragraph 1.E., “Compliance,” until all applicable requirements of paragraph (h) of this AD have been accomplished.
Unsafe condition
This AD was prompted by a report that the protective finishes on the forward trunnion pins for the left and right MLG might have been damaged during final assembly. We are issuing this AD to prevent stress corrosion cracking of the forward trunnion pins, which could result in fracture of the pins and consequent collapse of the MLG.
Affected ADs
This AD supersedes AD 2009-24-07, Amendment 39-16095 (74 FR 62231, November 27, 2009).
