Airworthiness Directive · Amendment 39-9044 · Bombardier Inc. Airplanes
Bombardier Inc. Airplanes
This AD applies to Bombardier Inc. DHC-8-102, DHC-8-103, DHC-8-106.
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 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.
