## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 767-300 and 767-300F series airplanes equipped with General Electric or Pratt & Whitney engines. This proposal would require reworking the wing-to-strut diagonal braces and the aft pitch load fittings of the wings, and reinstalling the diagonal braces with new fuse pins and associated hardware. For certain airplanes, this proposal would require replacing the bushings of the aft pitch load fittings, installing new fuse pins, and reworking the fittings, as applicable. This action is necessary to prevent undetected loss of the diagonal brace fuse pins of the wings and consequent increased loads in other wing-to-strut joints, which could result in separation of the struts and engines from the wings. This action is intended to address the identified unsafe condition.
