## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 767-200, -300, and -300F series airplanes. This proposal would require performing, for both main landing gear (MLG), gap measurements of the upper and lower joint gaps; an ultrasonic inspection of the outer cylinder of the MLG for cracks between the downlock fitting attach lugs; and follow-on and corrective actions if necessary. This action is necessary to detect and correct cracks in the outer cylinder of the MLG, which could result in collapsed MLG and consequent reduced controllability of the airplane during takeoff and landing. This action is intended to address the identified unsafe condition.
