## Discrepancy

WHEN PILOT SELECTED GEAR DOWN, INCOMPLETE EXTENSION OCCURRED.  ATTEMPTS TO EXTEND THE GEAR MANUALLY ALSO FAILED.  GEAR COLLAPSED ON LANDING. Z AN INSPECTION FOUND THAT THE COUPLING BETWEEN THE GEAR MOTOR AND ACTUATOR WAS SEPARATED.  THE MOTOR WAS FOUND NOT TO OPERATE ALSO.  THE ACTUATOR ASSEMBLY IS 30+ YEARS OLD.
