Summary
We propose to supersede airworthiness directive (AD) 2012-12- 08, which applies to certain The Boeing Company Model 777-200 and -300 series airplanes. AD 2012-12-08 requires an inspection for the part number of the fuse pin, and replacement of the pin if necessary. Since we issued AD 2012-12-08, we have determined that additional airplanes may be subject to the identified unsafe condition. This proposed AD would retain the actions required by AD 2012-12-08 and add airplanes to the applicability. We are proposing 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.
