RWY EXCURSION IN CORPORATE JET AFTER LOSS OF ANTI SKID BRAKING AND TIRES BLOW. LNDG PROC LNDG OVERSHOT. LOSS OF ACFT CTL. ACFT DAMAGED.

Narrative

WE STARTED OUR DSCNT APPROX 40 MI FROM THE WAUCHULA ARPT; AT WHICH TIME THE DSCNT CHKLIST WAS REVIEWED ALONG WITH LNDG DATA. AT APPROX 13 MI OUT WE CANCELED IFR AND PROCEEDED VISUALLY TOWARDS WAUCHULA. AT APPROX XB40 AM; LNDG CHKLIST WAS COMPLETE AND I PROCEEDED TOWARDS RWY 18 FOR A STRAIGHT-IN LNDG (WE WERE COMING FROM THE N). WITH FULL FLAPS AND LNDG GEAR DOWN AND LOCKED; WE CROSSED THE RWY THRESHOLD AT APPROX 135 KTS (NORMAL VREF SPD IS USUALLY 110 KTS; I ADDED THE EXTRA SPD BECAUSE OF THE GUSTY CONDITIONS AT WAUCHULA ARPT). AIRPLANE TOUCHED DOWN APPROX 1000 FT FROM THRESHOLD. I APPLIED BRAKES AND CALLED FOR GND FLAPS WHICH WERE DEPLOYED. I CONTINUED TO BRAKE (NOTE: ANTI-SKID ARMED) FOR APPROX 800 FT WHEN R WHEEL LOCKED AND BEGAN TO SKID. APPROX 1500 FT FROM END OF RWY; THE R MAIN BLEW. AT THIS TIME I FELT NOT ENOUGH RWY REMAINED TO INITIATE A GAR AND CONTINUED MAX BRAKING. APPROX 1000 FT FROM THE END OF THE RWY THE L MAIN BLEW. ACFT CONTINUED TO SLIDE OFF END OF RWY THROUGH THE GRASS OVERRUN AREA (APPROX 200 FT) ACROSS A DRAINAGE DITCH (15 FT WIDE; 8 FT DEEP) AND CAME TO REST ON THE S SIDE OF THE DITCH. MY COPLT GOT OUR PAX OUT THE MAIN DOOR OF ACFT AND I SECURED ACFT; SHUT DOWN BOTH ENGS; TURNED BATTERY MASTER OFF; AND EVACED ACFT. BESIDES WHAT I HAVE DESCRIBED IN NARRATIVE SECTION; HINDSIGHT IS ALWAYS 20/20. IF LEFT TO DO OVER AGAIN; I WOULD HAVE INITIATED A GAR BEFORE I GOT TO A POINT WHERE I NOT LONGER HAD AN OPTION.
