Narrative

AFTER DEP WE RECEIVED AN ECAM MESSAGE FOR A BSCU #1 FAULT AND AN AUTOBRAKE FAULT ALONG WITH AN ABNORMAL LGCIU INDICATION ON THE WHEEL PAGE. AS WE ROTATED AND I WAS LOOKING TOWARDS THE GEAR HANDLE IN ANTICIPATION OF THE GEAR UP CALL; I SAW THE RED UNLOCK LIGHT COME ON JUST BEFORE THE GEAR WAS SELECTED UP. WE CONSULTED WITH MOC AND RESET THE BSCU SWITCH TO BSCU #2. WE THEN HAD A BSCU #2 FAULT. WE CYCLED THE SWITCH BACK TO BSCU #1 AND STILL HAD THE FAULT. MOC SUGGESTED WE SWITCH BACK TO THE BSCU #2 FAULT SINCE THAT IS WHAT THEY WERE INDICATING. THEY ADVISED THAT AS LONG AS WE DID NOT HAVE BSCU #1 AND #2 FAULTED AT THE SAME TIME THAT WE WOULD STILL HAVE NORMAL BRAKING. AFTER REFING FCOM #3 IN THE EXPANDED PART OF THE LNDG GEAR SECTION; THE IMPRESSION WE WERE GETTING WAS THAT ONE OF THE LGCIU'S WAS HAVING A PROB. ON APCH WHEN LNDG GEAR WAS SELECTED DOWN WE RECEIVED A RED UNLOCK LIGHT ON THE L MAIN GEAR. DSCNT WAS STOPPED AND WE TOLD TWR OF OUR UNSAFE GEAR INDICATION. WE WERE CLRED FOR HOLDING. WE CYCLED THE LNDG GEAR AND THE UNLOCK LIGHT RETURNED. THE CAPT CALLED THE 1ST FLT ATTENDANT AND TOLD HER OF OUR INDICATIONS AND THAT WE WOULD BE A FEW MINS CONSULT TING WITH MOC AND THAT HE WOULD GET BACK TO HER. THE CAPT MADE AN ANNOUNCEMENT TO THE PAX THAT WE HAD AN INDICATION PROB THAT WE WANTED TO CONSULT WITH OUR MAINT DEPT ABOUT. WE REACHED MOC AND CONSULTED WITH THEM ON WHAT INDICATIONS WE HAD WHICH POINTED TO AN LGCIU #1 PROB. I CONFIRMED WITH THEM THAT HAVING 3 GREEN TRIANGLES ON THE WHEEL PAGE; CONFIRMED THAT THE GEAR WAS DOWN AS THIS IS ACTUALLY THE PRIMARY INDICATOR. REFING FCOM #3 AGAIN WE PREPARED FOR A LNDG WITH ALTERNATE BRAKING AND ONLY REVERSE THRUST ON ENG #2. AS THIS WOULD BE A NORMAL LNDG BUT WITH ALTERNATE BRAKING THE VEHICLES WERE ASKED TO STAND BY. THE 1ST FLT ATTENDANT WAS TOLD THAT WE IN FACT HAD AN INDICATION THAT ALL 3 GEARS WERE DOWN AND LOCKED BUT THAT THE CAPT HAD ASKED FOR THE VEHICLES TO BE AT THE RWY AS A PRECAUTION; BECAUSE WE WERE LNDG WITH ALTERNATE BRAKES. THE PAX WERE TOLD THAT OUR GEAR INDICATION HAD BEEN SORTED OUT AND THAT A SAFE LNDG WOULD BE MADE SHORTLY. THE LNDG WAS UNEVENTFUL. ON POSTFLT INSPECTION WE FOUND THAT THE L MAIN INBOARD TIRE TREAD HAD SEPARATED FROM THE TIRE. IN THE PROCESS IT DAMAGED THE WING FLAP AND AN AREA IN THE WHEEL WELL JUST ABOVE THE TIRE. A MECH POINTED OUT AN AREA WHERE A CANNON PLUG LOOKED TO BE DAMAGED AND SAID THAT IT COULD HAVE LED TO THE INDICATION PROBS THAT WE HAD. THE LNDG GEAR DOORS WERE OPENED IN SEARCH OF OTHER DAMAGE OR PIECES OF THE TIRE; NONE WERE FOUND. AS A RESULT WE CALLED THE DISPATCHER AND TOLD HIM OF OUR FIND AND THAT THERE MIGHT BE UNDISCOVERED TIRE DEBRIS ON THE DEP RWY. WE ALSO RELAYED THIS INFO TO SOC. THE CAPT THEN CALLED THE DUTY OFFICER AND RELAYED THE EVENTS ABOVE AND ASKED IF WE NEEDED TO CALL OR NOTIFY ANYONE ELSE AND HE SAID NO THAT AN EVENT RPT SHOULD DO IT.
