## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 767-200, -300, -300F, and -400ER series airplanes equipped with General Electric Model CF6-80C2 series engines. This action requires various repetitive inspections and tests of certain fail-safe features of the thrust reverser control system; and corrective actions, if necessary. This action is necessary to ensure that the fail-safe features of the thrust reverser are fully functional and to protect against an in-flight thrust reverser deployment, which could result in loss of controllability of the airplane. This action is intended to address the identified unsafe condition.
