主旨摘要

This AD requires initial and repetitive shim checks of the hydromechanical unit/main engine control idler adapter on the accessory gearbox assembly and, depending on the results of the shim check, possible replacement of the inserts on idler adapter. As a terminating action, also requires a protrusion check and a pull-out test, and the replacement of inserts on the idler adapter that fail either test.
