## Summary

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 767 airplanes. This proposed AD was prompted by reports of cracks and heat damage on pivot joint components found during main landing gear (MLG) overhaul. For certain airplanes, this proposed AD would require repetitive inspections of the MLG pivots, truck beam bushings, and inner cylinder bushings. For all airplanes, this proposed AD would require a maintenance program revision, one-time inspections of the MLG truck beam, and related investigative and corrective actions (including configuration changes) if necessary; accomplishment of these actions would terminate the repetitive inspections. We are proposing 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.
