## Summary

The FAA is revising an earlier proposed airworthiness directive (AD) for certain Boeing Model 767-200, -300, and -300F series airplanes. The original NPRM would have required verifying the part and serial numbers of certain main landing gear (MLG) bogie beam pivot pins; replacing those pivot pins with new or overhauled pivot pins if necessary; and ultimately replacing all pivot pins with new, improved pivot pins. The original NPRM was prompted by reports indicating that numerous fractures of the MLG bogie beam pivot pin have been found and that some pivot pins may have had improper rework during manufacture. This action revises the original NPRM by adding new inspections; revising the inspection thresholds and repetitive intervals; and revising the compliance time for replacing all pivot pins with new- material pins. We are proposing this supplemental NPRM to prevent fracture of the MLG bogie beam pivot pin, which could lead to possible loss of the MLG truck during takeoff orlanding and consequent loss of control of the airplane.
