Airworthiness Directive · Amendment 39-17782 · Landing gear
The Boeing Company Airplanes
This AD applies to The Boeing Company Model 777-200 and -300 series airplanes, certificated in any category, as identified in Boeing Special Attention Service Bulletin 777-32-0083, Revision 2, dated May 2, 2013.
We are superseding Airworthiness Directive (AD) 2012-12-08 for certain The Boeing Company Model 777-200 and -300 series airplanes. AD 2012-12-08 required an inspection for the part number of the main landing gear retract actuator fuse pin, and replacement of the pin if necessary. This new AD retains the actions required by AD 2012-12-08 and adds airplanes to the applicability. This AD was prompted by a determination that additional airplanes may be subject to the identified unsafe condition. We are issuing this AD to prevent structural damage to the side and drag brace lock assemblies, which could result in landing gear collapse during touchdown, rollout, or taxi.
Except as required by paragraph (h) of this AD, at the applicable time specified in paragraph 1.E., “Compliance,” of Boeing Special Attention Service Bulletin 777-32-0083, Revision 2, dated May 2, 2013: Inspect the retract actuator fuse pin to determine the part number, and replace any retract actuator fuse pin having part number 112W1769-1, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777-32-0083, Revision 2, dated May 2, 2013. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the retract actuator fuse pin can be conclusively determined from that review. Except as required by paragraph (h) of this AD, do all applicable replacements at the applicable time specified in paragraph 1.E., “Compliance,” of Boeing Special Attention Service Bulletin 777-32-0083, Revision 2, dated May 2, 2013.
Where Boeing Special Attention Service Bulletin 777-32-0083, Revision 2, dated May 2, 2013, specifies a compliance time “after the Revision 2 date of this service bulletin,” this AD requires compliance within the specified compliance time after the effective date of this AD.
