## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 767-200 and -300 series airplanes powered by Pratt & Whitney JT9D series engines. This proposal would require replacement of the existing deactivation pin, aft cascade pin bushing, and pin insert on each thrust reverser half, with new, improved components. This action is necessary to prevent failure of the thrust reverser deactivation pins, which could result in deployment of the thrust reverser in flight and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
