This AD was prompted by reports of failure of the steering brackets of the nose wheel steering assembly of the landing gear, and in one incident, loss of steering control. We are issuing this AD to find and fix discrepancies of the nose wheel steering assembly which could result in loss of steering control and consequent reduced controllability of the airplane.
