Airworthiness Directive · Amendment 39-8993 · The Boeing Company Airplanes
The Boeing Company Airplanes
This AD applies to The Boeing Company 767-200 Series, 767-300 Series, 767-300F Series.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that currently requires inspections, adjustments, and functional tests of the thrust reverser system. This amendment adds a requirement for installation of an additional thrust reverser system locking feature, periodic functional tests of that locking feature following its installation, and repair of any discrepancy found. This amendment is prompted by the identification of a modification that ensures that the level of safety inherent in the original type design of the thrust reverser system is further enhanced. The actions specified by this AD are intended to prevent possible discrepancies in the thrust reverser control system that can result in inadvertent deployment of a thrust reverser during flight.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
