Plain English Summary

4/10 complexity

This Airworthiness Directive requires Boeing 767 operators to inspect, adjust, functionally check and modify thrust reverser gearbox locks and the airmotor, and to perform recurring operational checks to reduce the risk of inadvertent in‑flight thrust reverser deployment. It applies to aircraft owners/operators, who must complete initial work before a Certificate of Airworthiness and meet specified flight‑hour deadlines and recurring intervals; the Civil Aviation Safety Authority (Delegate) enforces compliance and operators bear the cost and scheduling burden.

Background: This Directive requires inspections, adjustments, functional checks, the installation of a modification and repetitive operational checks of the thrust reverser gearbox locks and the airmotor. These actions are intended to enhance the level of safety inherent in the original type design of the thrust reverser system to prevent possible discrepancies that exist in the current thrust reverser control system, that could result in an inadvertent deployment of a thrust reverser during flight.
