AN AIRBUS A320 PLT RPTS OF HAVING TO PERFORM ZERO FLAPS LNDG TWICE IN TWO DAYS WITH THE SAME ACFT. SUBSEQUENT FLT CREWS EXPERIENCED THREE MORE ZERO FLAPS LNDGS WITH SAME ACFT.

Narrative

WELL; NOW I STILL DON'T KNOW IF ANYTHING WE DID CONTRIBUTED TO THIS SECOND NO FLAP LNDG IN 2 NIGHTS; IN THE SAME AIRPLANE. I CAN ONLY COME UP WITH A MAINT SITUATION; BUT THE COINCIDENCE IS FRUSTRATING. AGAIN; THE ACFT CAME OUT OF HEAVY MAINT 2 DAYS EARLIER AND 1 DAY EARLY. IT WAS RUSHED I'VE BEEN TOLD. IT WAS AN UNEVENTFUL LNDG AGAIN.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THIS WAS THE SECOND TIME THIS SITUATION OCCURRED WITH THE SAME ACFT IN TWO DAYS; AND THAT DURING BOTH INCIDENCES; WHEN HE POSITIONED THE FLAP HANDLE FROM ONE DEG SETTING TO LEVEL TWO; THE SLATS EXTENDED; ALTHOUGH NOT FULLY; AND NO FLAP MOVEMENT. HE SAW AN ECAM MESSAGE THAT THE FLAPS HAD 'LOCKED' AND THEY REMAINED THAT WAY ALL THE WAY TO THE GATE. MAINT THOUGHT THEY HAD FIXED THE PROBLEM AFTER THE FIRST INCIDENT; BUT THAT WAS NOT THE CASE. THE PROBLEM REAPPEARED THE VERY NEXT DAY; ON HIS RETURN LEG. AGAIN; MAINT TRIED TO CONVINCE HIM THE ACFT WAS FIXED. HE WAS GIVEN ANOTHER ACFT. HOWEVER; THREE MORE ZERO FLAPS LNDGS OCCURRED WITH THE SAME ACFT IN THE FOLLOWING DAYS BY DIFFERENT CREWS. RPTR ALSO STATED HE WAS INFORMED BY MAINT THAT THE WING TIP BRAKES WERE EVENTUALLY REPLACED AND THIS SEEMS TO HAVE CORRECTED THE PROBLEM FOR NOW. THE INITIAL 'ZERO' FLAPS INCIDENT OCCURRED ON THE FIRST REVENUE FLT AFTER MAINT OVERHAUL WHEN HE WAS ON LNDG APCH.
