## Discrepancy

(CAN) IN FLIGHT, THE FLAP UP SWITCH FAILED CAUSING THE FLAP MOTOR TO DRIVE THE FLAPS TO A MORE UP POSITION WHICH BURNED OUT THE FLAP MOTOR AND TWISTED THE FLAP ACTUATOR DRIVE CABLES.   WE ARE REPLACING THE UP LIMIT SWITCH, FLAP ACTUATOR DRIVE CABLES, FLAP MOTOR AND GEARBOX AND 3 FLAP TRACKS WHICH ARE CLOSE TO THEIR MAX WEAR LIMITS. WE ARE INSPECTING THE FLAP ACTUATORS AND FLAP MOTOR CIRCUIT BREAKER.
