Airworthiness Directive · Amendment 39-5232 · The Boeing Company Airplanes
The Boeing Company Airplanes
This AD applies to The Boeing Company 767-200 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 action publishes in the Federal Register and makes effective as to all persons an amendment adopting a new airworthiness directive (AD) which was previously made effective to all known U.S. owners and operators of certain Boeing Model 767-200 airplanes by individual telegrams. The AD requires inspection and replacement, if necessary, of self-locking nuts located in certain critical areas of the airplanes. This action was prompted by the discovery that two elevator actuator rod end bolt retaining nuts on one recently delivered Model 767 airplane did not have their intended self-locking feature. Such a nut could back off its mating bolt and result in a disconnection of the affected joint. Multiple disconnections of elevator to actuator joints could result in partial or complete loss of airplane control. These nuts have other critical applications on the Model 767 airplane, which are also addressed in the AD.
