This Airworthiness Directive becomes effective on 20 September 2000.

Background: The FAA has received reports that elevator bellcrank assemblies with failed shear rivets have been found on three Model 767 aircraft. On one aircraft, the failed shear rivets were found in both the left inboard and left centre power control actuator bellcrank assemblies. Failure of two bellcrank assemblies on one side can result in that single surface moving to a hardover position independent of pilot command resulting in a significant pitch upset recoverable by the crew.
