Unsafe condition
This AD was prompted by a report of an invalid part number for the new nose landing gear wheel nut. We are issuing this AD to prevent separation of the wheels from the nose landing gear due to the failure of the outer wheel bearings, and consequent loss of control of the airplane during takeoff and landing.
