## Discrepancy

THE CREW RAN THE ABNORMAL CHECKLIST AFTER THEY RECEIVED A FLAP POWER CAUTION WHILE ON APPROACH. CIRCUIT BREAKER L-7 WAS RESET IAW THE CHECKLIST. THE CAUTION LIGHT WENT OUT AND THE FLAPS OPERATED NORMALLY. MAINTENANCE INSPECTED THE SERVICE LETTERS DH8-400-SL-27-004 AND 400-SL-27-002A. FLAP CONTROL C/B CL-72 WAS RESET TO COMPLY WITH FULL POST OF FLAP SYSTEM. ALL OPERATIONAL CHECKS WERE GOOD AND THE AIRCRAFT WAS RETURNED TO SERVICE.
