Narrative

ON APCH TO ZZZ AT APPROX 7500 FT MSL; WE RECEIVED A TCAS RA GENERATED FROM PARALLEL TFC THAT WAS BEHIND US AND NOT IN SIGHT. A GAR WAS INITIATED AND CLB TO ATC INSTRUCTED ALT OF 8000 FT WAS ACCOMPLISHED. CLEAN-UP AND ACCELERATION WAS NORMAL UNTIL A WINGTIP BRAKE ECAM WAS TRIGGERED; WITH FLAPS SELECTED IN POS #1. SPD AT THAT TIME WAS 190 KIAS AND SPD WAS SELECTED TO PREVENT FURTHER ACCELERATION. ECAM ACTION WAS COMPLETED. FOM WAS CONSULTED. ALL PROCS WERE FOLLOWED INCLUDING CALCULATION OF VREF ADDITIVE AND INCREASED LNDG DISTANCE. OUR FUEL SIT WAS CONSIDERED AND WE AGREED TO BE ON THE GND WITH NO LESS THAN 4000 LBS. WE DECLARED AN EMER TO ATC WITH A REQUEST TO HAVE THE CFR EQUIP TO BE STANDING BY. ATC VECTORED US N OF THE ARPT UNTIL WE NOTIFIED THEM WE WERE READY TO COMMENCE THE APCH. DISPATCH WAS ALSO NOTIFIED. APCH WAS HAND FLOWN WITH SPD SELECTED. TOUCHDOWN WAS IN THE TOUCHDOWN ZONE AT APPROX 2000 FT FROM APCH AND END OF RWY. ACFT DECELERATED NORMALLY AND WE EXITED AT TXWY AND CONTINUED TO GATE NORMALLY. ADDITIONAL DETAILS; WX VISIBILITY GREATER THAN 10 MI; WINDS WERE AT 190 DEGS AT 28 KTS GUSTING TO 38 KTS. INITIAL CONFIGN WAS MADE AT SPDS BELOW COMPANY SPDS FOR FLAP/GEAR SETTINGS. FLAP SELECTOR IN POS #3. V-APCH WAS FLOWN SELECTED AT 154 KIAS. VREF 129 KTS +25 KTS. LNDG DISTANCE WAS INCREASED BY 35%. AUTOBRAKES WERE USED. ATC DID NOT ALERT US TO PARALLEL TFC. IF WE HAD ACQUIRED TFC VISUALLY SOONER IN THE APCH; THE GAR MIGHT HAVE BEEN PREVENTED. TFC WAS BELOW AND BEHIND AND SLIGHTLY OVERTAKING US.
