AN A319'S LGCIU FAILED DURING LANDING ROLL OUT BELOW 70 KTS CAUSING THE NOSE WHEEL TO TURN 90 DEGS AND DISABLING THE ACFT ON THE RWY.

Narrative

WE HAD NO INDICATION (ECAMS; VIBRATIONS; SOUNDS; ETC) THAT ANYTHING WAS ABNORMAL DURING TAXI OUT FOR DEP; NORMAL TKOF; CLB; CRUISE; AND DSCNT; APCH AND INITIAL TOUCHDOWN FOR LNDG. THE LNDG WAS SUPER SOFT/SMOOTH; REVERSED THRUST; LOWERED THE NOSEWHEEL VERY SMOOTH AND GENTLY TO THE RWY FOR A NORMAL LNDG. ALL AT ABOUT THE SAME TIME AND WITHIN SPLIT SECONDS; AS I CAME UP TO IDLE REVERSE; FO CALLED 70 KTS; MY HAND WAS BEING PLACED ON THE TILLER WHEEL; STARTING TO PUT ON THE BRAKES SO THAT WE COULD EXIT AT THE NEXT TXWY; THE ACFT STARTED VIBRATING AND SHAKING EXCESSIVELY. I REALIZED QUICKLY THAT THE RUDDERS; NOT THE TILLER WERE STILL MY MOST EFFECTIVE WAY AT KEEPING THE ACFT ON THE CTRLINE OF THE RWY UNTIL WE CAME TO A COMPLETE STOP. THEN WE GOT AN ECAM L/G LGCIU 1 FAULT. WE TALKED WITH TWR; FLT ATTENDANTS; PAX; MAINT; CHIEF PLT; ZZZ OPS AND THE FIRE DEPT CAME OUT TO TAKE A CLOSER LOOK UNDER THE ACFT AND THEY INFORMED US THAT THE NOSEWHEEL WAS 90 DEGS OFF THE PERPENDICULAR AXIS OF THE ACFT AND THAT THERE WAS METAL AND RUBBER ON THE RWY BEHIND THE ACFT. NO EMER WAS DECLARED. RWY XXR WAS CLOSED UNTIL ACR'S MAINT DEPT ARRIVED THAT NIGHT TO EVAL AND MOVE THE ACFT TO ANOTHER LOCATION ON THE ARPT. ACR'S OPS BROUGHT AIRSTAIRS AND BUSES OUT TO THE ACFT AND DEPLANED THE PAX ON THE RWY. ARPT MGR; ACR'S STATION MGR AND OTHER EMPLOYEES ALSO CAME OUT TO THE ACFT TO OFFER ASSISTANCE. THE CAPT AND FO STAYED WITH THE ACFT UNTIL ACR'S MAINT ARRIVED THAT NIGHT. FIRE DEPT WAS CALLED TO DO A CLOSE-UP INSPECTION FOR ANY POSSIBILITY OF SMOKE OR FIRE. THEY FOUND NO INDICATION OF SMOKE OR FIRE.
