ACR LANDED LONG AND HOT AND WENT TO THE OVERRUN.

Narrative

LANDED AT CHICAGO O'HARE FIELD ON RWY 4R. LANDED LONG; REVERSED; USED BRAKES: USED HVY BRAKING AT END OF LNDG ROLL. ACFT STOPPED WITH NOSE HANGING OVER END OF RWY. ALL 3 OF US PLTS THOUGHT THAT WE WOULD STOP IN TIME TO MAKE A NORMAL RWY TURN OFF AND WERE ALL SURPRISED WHEN WE DID NOT STOP IN TIME. WE ALL 3 THOUGHT THAT THERE WERE EXCESSIVE BRAKE RELEASES AT THE END OF THE LNDG ROLL. MADE A 180 DEG TURN TO THE R; THEN ANOTHER 90 DEG TURN TO THE R TO EXIT RWY. I TURNED IN THIS DIRECTION BECAUSE IT SEEMED THAT THE MOST TURNING ROOM WAS IN THIS DIRECTION. TAXIED IN WITHOUT INCIDENT. ALL SYS WERE NORMAL ON TAXI TO GATE. REQUESTED MAINT INSPECT TIRES AND BRAKES. WE WERE NOTIFIED UPON ARR AT GATE THAT WE HAD BROKEN SOME GND LIGHTS AT END OF RWY. THERE WAS DAMAGE TO 1 NOSE WHEEL AND 1 MAIN WHEEL; WHICH I BELIEVE WERE CHANGED. THE FOLLOWING IS WHAT CAUSED THE TOUCHDOWN TO BE LONG. THE AUTOPLT WAS ENGAGED AND WE WERE TRACKING THE LOC AND GS FROM 9000 FT- TO ABOUT 500 FT. APPARENTLY OUR SLATS WERE EXTENDED AND OUR FLAPS WERE AT ZERO. OUR SPD WAS PROBABLY ABOUT 210 KTS. AT THAT POINT (500 FT) THE GND PROX WARNING SYS (GPWS) SAID 'TERRAIN; GEAR.' AT THAT MOMENT I ORDERED; 'GEAR DOWN.' AS THE GEAR CAME DOWN AND THE COPLT-PLT EXTENDED THE FLAP HANDLE TO LNDG POS OF 35 DEGS; I WORKED WITH THE ACFT TO GET IT ON THE GND. WHAT HAPPENED BTWN 9000 FT AND 500 FT? THIS IS THE BIG QUESTION. WE SHOULD NOT HAVE ARRIVED AT 500 FT WITH GEAR UP AND SPD AT 210 KTS. THIS IS ABSOLUTELY CONTRARY TO SOP AND UNACCEPTABLE FLYING. TO THINK OF IT SICKENS ME. DURING THE APCH I WAS RELAXED. I DON'T KNOW FOR SURE; BUT IT SEEMS I HAD MY ATTN FIXED ON THE RWY. IT WAS AS IF I HAD TUNNEL VISION WITH MY SIGHT AND HEARING. A CONTRIBUTING FACTOR MAY HAVE BEEN THAT I GOT 6 HRS OF SLEEP THE NIGHT BEFORE AND 4 HRS OF SLEEP THE NIGHT BEFORE THAT. HOWEVER; WHEN I GOT UP IN THE MORNING AND SHOWERED; I FELT OK. I SEEMED TO SENSE; DURING THE APCH; THAT THE ACFT WAS IN LNDG CONFIGN WITH GEAR DOWN; FLAPS IN LNDG POS AND AIR SPD AT APCH SPD. WHEN THE WARNING (GPWS) SOUNDED AT 500 FT; I WAS STARTLED AND CONFUSED. I COULDN'T BELIEVE THAT WHAT WAS HAPPENING; WAS ACTUALLY HAPPENING. 1) ALTHOUGH THE WX WAS GOOD AND THE RWY RPTED DRY; I WONDER IF THE END OF THE RWY SUPPLIED POOR BRAKING BECAUSE OF RUBBER; OIL; PAINT OR POSSIBLY DE-ICING FLUID DEPOSITS. THE CONDITION OF THE RWY SHOULD BE CHKED. 2) AT 500 FT I SHOULD HAVE MADE A GAR; WHICH IS SOP. WHY DIDN'T I? THE ORAL GPWS WARNING SOUNDED LIKE A COMMANDED; 'GEAR.' I RESPONDED TO THIS SPEAKER WORD; GEAR. OBVIOUSLY; IF A CREW GETS THEMSELVES INTO THIS SIT; THEY ARE NOT FUNCTIONING PROPERLY. THEREFORE THEY PROBABLY WILL NOT RESPOND AT A HIGH LEVEL OF PROFICIENCY. I BELIEVE IT WOULD BE BETTER IF THE GPWS WAS PROGRAMMED IN THAT SIT TO SAY 'GAR.' THIS WOULD SIGNAL A SOLUTION INSTEAD OF NOTIFYING THAT SOMETHING IS WRONG.
