Background: This directive has been issued in response to a report of worn throttle lever stops resulting in an engine stopping in flight. Worn throttle stops required the pilot to exert a high level of force to move the throttle. In the engine stoppage event, when attempting to close the throttle during landing approach, the butterfly control arm was forced beyond the idle position.
