## Discrepancy

(CAN) FLAPS WOULD WORK AS NORMAL, EVEN AFTER 4 HOUR FLIGHT AT -45. AFTER LANDING & SELECTING FLAPS UP,  (FLAPS) CAUTION WOULD COME ON NR FLAPS WOULD NOT MOVE. NORMAL GROUND RESET WOULD NOT WORK. FLAP CONTROL 1 AMP C/B APPEARED TO BE (BLOWN) BUT NOT POPPED. AFTER RESETTING C/B, NORMAL FLAP RESET WOULD WORK. TRYING TO MOVE FLAPS AGAIN WOULD CAUSE THE SAME PROBLEM. NOTE THIS DEFECT WOULD ONLY OCCUR IF THE GROUND TEMP WAS -5 TO -12. AFTER WARMING THE AIRCRAFT IN A HANGAR FLAPS WOULD RESET NR WORK. UPON INSPECTION OF THE ACTUATORS IT WAS DISCOVERED THAT 3 OF THE 4 ACTUATORS WERE HEATING UP. +40 TO +50 C. ACTUATORS WERE REMOVED FROM SERVICE. ALSO NOTED WAS FLAP CONTROL WARNING UNIT FAILURE CODES INCLUDED TOO HIGH CUR
