## Discrepancy

APPROXIMATELY 1500 FEET AFE (4500MSL) ON FINAL FLAPS 35 DEG WAS SELECTED FROM 15 DEG FLAPS DID NOT RESPOND AND WE GOT A FLAP POWER CAUTION. AFTER EXECUTING A MISSED APPROACH WE RAN THE E&A CHECKLIST FOR A FLAP POWER CAUTION, IT CALLED FOR A CB RESET WHICH WE DID. THIS CLEARED THE CAUTION. WE RETRACTED THE FLAPS TO 0 DEG AND DIVERTED. UPON SELECTING 35 DEG ON FINAL WE ENCOUNTERED THE SAME CAUTION. AGAIN WE RAN THE E+A CHECKLIST, BUT LEFT FLAPS AT 15 DEG AND PERFORMED A NORMAL FLAPS 15 DEG LANDING. REMOVED FROM SERVICE. C/W FIM 27-50-00-810-802. FOUND "ARMING SWITCH" IN CDS. FAULT CLEARED & DID NOT RETURN DURING OPS CHECKS. NO HISTORY IN TRAX. A/C OK FOR CONTINUED SERVICE.
