AN A320 FLT CREW EXPERIENCED AN ENGINE SURGE AT AN INTERMEDIATE LEVEL OFF ALTITUDE. THEY SELECTED ANOTHER TLA CHANNEL AND CONTINUED TO DEST.

Narrative

WE DEPARTED ZZZ AFTER A NORMAL PREFLT; START AND TAXI. THERE WAS A PREVIOUS WRITE-UP ON A #1 ENG STALL. IT LOOKED LIKE IT WAS CHKED OUT AND EVERYTHING LOOKED OK. WE TOOK OFF AND WERE GIVEN AN INTERMEDIATE LEVELOFF OF FL210 ON THE SID. 3 MINS INTO THE LEVELOFF; WE HAD A MODERATE YAW TO THE R AND NOTICED THE #1 ENG AT MAX EPR AND DECREASING. WE LOST #1 ENG OIL QUANTITY (SHOWED XX). THE AUTOPLT WAS ON AND STAYED CONNECTED. OIL QUANTITY CAME BACK A FEW MINS LATER (ON #1) AND READ 26.0. WE HAD ABOUT 19.0 PRIOR TO START. A FEW MINS AFTER THAT; THE 'A' FLT ATTENDANT CALLED AND ASKED WHAT WE WERE DOING. I ASSURED HER ALL WAS WELL AND I WOULD GET BACK TO HER. WE HAD AN ECAM OF ENG #1 ONE TLA FAULT. THE #1 ENG OIL QUANTITY STAYED AT 26.0 VERSUS #2 ENG QUANTITY AT APPROX 19.0. WE NOTIFIED MAINT CTL AND DISPATCH WITH WRITE-UPS ON THE EVENT. WE MONITORED THE ENG AND DECIDED IF FURTHER PROBS WERE ENCOUNTERED WE WOULD DIVERT. DISPATCH AND MAINT CTL WERE KEPT IN THE LOOP. WE DID PULL THE CURRENT LEG ECAM RPT AND IT SHOWED AN ENG #1 FADEC AND ENG #1 TLA FAULT. IT ALSO SHOWED A RPT OF CHK OIL QUANTITY XMITTER 1. THIS SEEMED TO BE AN ENG SURGE RATHER THAN A STALL. WE HAD AN INCREASE IN THE EPR AND EGT THAT RETURNED TO NORMAL LIMITS AND STAYED THERE. IT ONLY HAPPENED ONCE. WE THINK THE TLA CHANNEL ON THE #1 ENG WAS FAULTY AND SWITCHED TO THE OTHER CHANNEL. I UPDATED THE FLT ATTENDANT AND REASSURED HER THAT WE WOULD MONITOR THE SITUATION AND THINS WERE OK FOR THE TIME BEING. NO OTHER PROBS WERE ENCOUNTERED AND WE CONTINUED TO ZZZ1. WE LANDED AND TAXIED WITH NO FURTHER INCIDENT. MAINT SAID THE PLANE WOULD BE IN ZZZ1 FOR A WHILE.
