What was found
(CAN) AFTER LANDING, FLAPS SELECTED FROM 17 DEGREES TO ZERO DEGREES. THE FLAPS DID NOT RESPOND. MAINTENANCE FOUND THAT THE TRANSMISSION/MOTOR ASSEMBLY HAD INTERNALLY SEPARATED AND THE ASYMMETRY SWITCH LOCKED OUT FURTHER MOVEMENT. THE TRANSMISSION/MOTOR WAS REPLACED. WHEN THE MANUAL OVERRIDE WAS SELECTED THE OUTER FLAPS RETURNED TO FULL UP AND THE INNER PANELS STAYED DEPLOYED AT 17 DEGREES.
