## Discrepancy

DURING CLIMB THE FLAPS WERE RETRACTED TO ZERO, SHORTLY AFTER THE CREW RECEIVED A FLAP FAIL CAUTION MESSAGE. THE FLIGHT CONTINUED AND THE CREW PERFORMED A FLAPLESS LANDING WITHOUT FURTHER INCIDENT. LOCAL MX FOUND THE FLAPS CONT CH1 AND FLAPS CONT CH2 CIRCUIT BREAKERS (CB) OPEN. THESE CB ARE LOCATED ON 2 DIFFERENT CB PANELS.  CBS WERE RESET, THE SYS TESTED AND THE ACFT RELEASED INTO SERVICE. SIMILAR DEFECT WAS REPORTED LATER DURING THE CREW PRE-FLIGHT INSPECTION. THE ACFT WAS FERRIED TO A MAIN MAINT BASE WHERE THE FOLLOWING PARTS WERE REPLACED: FLAPS ELECTRONIC CONTROL UNIT, PN 601R93050-7 SN 227, RT BRAKE POSITION SENSOR UNIT PN 855D100-13, SN 1497B AND ITS ASSOCIATED HARNESS.
