This AD results from a production defect found in certain actuators during overhaul of the pilot's and co-pilot's seats. We are issuing this AD to prevent uncommanded movement of the pilot's or co-pilot's seat, which could result in interference with the operation of the airplane and consequent temporary loss of airplane control.
