Unsafe condition
This AD results from reports of the loss of directional control of the airplane on the ground after an internal failure of the steering system of the nose landing gear (NLG) wheel. We are issuing this AD to prevent failure of the NLG wheel steering system, which could result in reduced controllability of the airplane.
