Airworthiness Directives; de Havilland Model DHC-8-100 Series Airplanes Federal Register ↗

Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain de Havilland Model DHC-8-100 series airplanes, that requires modification of the potentiometer lever stops on the nose wheel steering. This amendment is prompted by a report that the potentiometer stops installed currently on these airplanes are too short to limit excessive uncontrolled potentiometer movement in the event of a mechanical link failure. The actions specified by this AD are intended to prevent the airplane from departing the runway during takeoff or landing in the event of the failure of the mechanical link between the rudder pedals and the potentiometer.
