KINGAIR 90 FLT CREW HAS A RWY EXCURSION AT HLG.

Narrative

WE EXITED THE RWY AT HLF WITH A BLOWN TIRE. THERE WAS NO OTHER DAMAGE (NEITHER ACFT; PERSONAL NOR PROPERTY). THE EVENT WAS A RESULT OF FATIGUE AND A FALSE SENSE OF SECURITY. THE COPLT; A 4 YR VETERAN; WAS FLYING. HE PERFORMED NORMALLY PRIOR TO THE EVENT. THE WX WAS IFR WITH A 500 FT CEILING; CALM WINDS AND 2 1/2 MI VISIBILITY ON THE ILS TO RWY 3 AT HLG. WE WERE VECTORED ONTO FINAL ABOUT 2 MI OUTSIDE OF THE MARKER. HE HAD APCH FLAPS AND 150 KTS. HE LOWERED THE GEAR JUST BEFORE CAPTURING THE GS. FROM THAT POINT ON THE ESSENTIALLY SHUT DOWN. HE INITIALLY FAILED TO CAPTURE THE GS. RECOGNIZING THAT VIA MY PROMPTING THAT THE GS WAS BELOW US HE STARTED A 1000 FPM DSCNT TO RE-INTERCEPT. HE DID NOT REDUCE THE PWR AS REQUIRED BY THE ACCELERATED RATE OF DSCNT. IRONICALLY I SAID 'YOU'VE GOT TO SLOW DOWN; WE DON'T WANT TO GO OFF THE END OF THE RWY.' HE RESPONDED; 'I WOULD NEVER DO THAT TO YOU.' I AGAIN INFORMED HIM THAT WE WERE FAST; AND HE ACKNOWLEDGED. WE BROKE OUT AT 500 FT WITH THE GEAR DOWN AND APCH FLAPS BUT WITH 140 KTS STILL. I AGAIN TOLD HIM WE WERE FAST AND HE ACKNOWLEDGED. AT 200 FT WE WERE STILL TOO FAST FOR FULL FLAPS (130 KT LIMIT) SO I TOLD HIM TO 'JUST PULL THEM TO IDLE.' AGAIN HE ACKNOWLEDGED BUT THERE WAS LITTLE PHYSICAL MOVEMENT. WE TOUCHED DOWN AT 2000 FT WITH 3000 FT REMAINING AT APPROX 120 KTS WITH APCH FLAPS. I HAD A FALSE SENSE OF SECURITY FROM THE KING AIR'S NORMAL STOPPING PERFORMANCE COUPLED WITH THE FO'S NORMAL PERFORMANCE. THE PROB WAS THAT HE HAD PHYSICALLY SHUT DOWN AND DID NOT GO INTO REVERSE EVEN THOUGH HIS HAND WAS IN POS TO DO SO. AT 2000 FT REMAINING AND 100 KTS; HE APPLIED TOE BRAKING WITH LITTLE EFFECT. I WAS RELUCTANT TO ABORT THE LNDG AT THIS POINT BECAUSE THE BRAKES WERE BECOMING EFFECTIVE AND WE WERE CLOSING IN ON LESS THAN 1500 FT REMAINING. I HELPED APPLY MAX BRAKING AT 1000 FT REMAINING FAVORING THE L RUDDER TO ENSURE WE WOULD MISS THE LIGHTS AT THE END. THIS ACTION LOCKED THE L TIRE AND CAUSED IT TO FAIL. WE WENT OFF INTO THE GRASS WHICH WAS VERY WET AND SLIPPERY DUE TO CONDENSATION AND INTERMITTENT GND FOG. THE ACFT SKIDDED TO A STOP WITH NO DAMAGE.
