## Discrepancy

(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.
