## Discrepancy

(CAN) DURING AIRCRAFT TAXI CREW SELECTED FLAPS TO 17 DEGREES FOR TAKEOFF. FLAPS DID NOT OPERATE. FLAPS RE-SELECTED AND FLAPS MOVED TO SELECTED POSITION. CREW SELECTED FLAPS TO 0 DEGREE POSITION AND OPERATED ON THE M.E.L.MAINTENANCE WAS ABLE TO DUPLICATE FAULT AND FOUND LOW VOLTAGE OUTPUT FROM FLAP MOTOR RELAY. RELAY REPLACED, VOLTAGE OUTPUT CHECKED OKAY, AND FLAP OPERATION CHECKED OKAY. OPERATORS RELIABILITY PROGRAM INDICATES THIS RELAY HAS BEEN REPLACED IN THE PAST FOR THE SAME FAULT. OPERATOR IS PLANNING TO IMPLEMENT A LIFE LIMIT ON THIS PART.
