## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus transport category airplanes. This proposed AD would require inspecting to determine if a certain actuator is installed in the pilot's or co-pilot's seat, and doing applicable corrective actions if necessary. For certain actuators, the proposed AD also would require replacing rotors on both vertical and horizontal movements with new rotors, and replacing the clutch cap with a new cap. This proposed AD results from a report of heavy wear at the driving gear of the rotor shaft end of the electrical driven motor on certain actuators of the pilot's and co-pilot's seats. We are proposing this AD to prevent uncommanded movement of the pilot's or co-pilot's seat during takeoff or landing, which could result in interference with the operation of the airplane and consequent temporary loss of airplane control.
