Narrative

AFTER TKOF AND INITIAL POWER REDUCTION; WE GOT AN ECAM F/CTL CAUTION WITH THE FLAPS LOCKED. UPON SELECTING FLAPS UP; THE TRAILING EDGE FLAPS REMAINED AT F1. SLATS RETRACTED NORMALLY. ADVISED ATC AND FLT ATTENDANTS. CAPTAIN FLEW ACFT AND HANDLED ATC. FO RAN CHECKLISTS AND TALKED TO DISPATCH AND MAINT. ACFT CHECKLISTS COULD NOT SOLVE PROBLEM. MAINT AGREED WITH CAPT TO RETURN TO FIELD. APPROPRIATE APPROACH AND LANDING CHECKLISTS AND CHARTS WERE REFERENCED. ACFT WEIGHT WAS WELL UNDER LANDING WEIGHT. A FLAPS 3 APPROACH AND LANDING WERE MADE. SLATS WERE IN 3 POSITION. FLAPS REMAINED LOCKED AT THE FLAPS 1 POSITION. LANDED SAFELY WITHOUT INCIDENT.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE REPORTER STATED THAT THE ACFT HAD COME FROM OVERNIGHT MAINTENANCE PRIOR TO HIS FLT. AFTER THE ECAM ANNUNCIATION INFLT; DISCUSSIONS WITH MAINTENANCE HAD THE CREW CYCLING THE FLAPS WHICH DID NOT CLEAR THE PROBLEM. THE SLATS OPERATED NORMALLY INFLT BUT THE FLAPS REMAINED LOCKED AT 1 DEG. AFTER LANDING; THE CREW CYCLED THE FLAPS WITH THE SAME RESULTS. ONCE THEY WERE AT THE GATE; MAINTENANCE CYCLED THE YELLOW HYDRAULIC SYSTEM; AND AS THE FLAPS WERE CYCLED; THE FLAPS LOCKED ECAM WAS CLEARED. THE CREW REFUSED THE ACFT.
