GA SMA LANDED LONG AND HAD A RWY EXCURSION OFF THE END OF THE RWY. GEAR COLLAPSED CROSSING A DITCH CAUSING ACFT DAMAGE.

Narrative

LATER THE SDF APCH TO RWY 28; WINDS OUT OF THE W; SPOTTED THE RWY 1 1/2 FROM END OF RWY; COULD PLAINLY SEE A LARGE HANGAR AT OTHER END OF RWY (5019'); THEREFORE ESTABLISHED VIS TO BE 2 1/2 MI; MADE NORMAL APCH; WHEN WE TOUCHED DOWN ON RWY HAD 2500' LEFT. DURING LNDG ROLL APPLIED THE BREAKS AND GOT NO RESPONSE; CONTINUED PUMPING BRAKES TO NO AVAIL; WENT OFF THE END OF RWY (NOSE WHEEL WAS ON THE CENTER LINE ENTIRE TIME). CAME TO REST APPROX 80' FROM END OF RWY. WHEN LEFT MAIN GEAR HIT A DITCH IT FOLDED UNDER THE WING. MINIMAL DAMAGE TO LEFT MAIN GEAR AND LEFT WING. CONTRIBUTING FACTOR WAS PROBABLY THE AMOUNT OF WATER ON THE RWY. IN LNDG; I HAD TOUCHED DOWN SAME PLACE BEFORE; MANY TIMES--SO I DIDN'T THINK THERE WAS ANY PROBS UNTIL I COULDN'T GET ANY BRAKING ACTION. I DECIDED TO STAY ON THE GND AND NOT TRY AND GO AROUND BECAUSE OF HIGH PWR LINES ON THIS END OF RWY. I FEEL CONFIDENT I MADE THE RIGHT DECISION IN NOT ATTEMPTING A GO AROUND. I COMMITTED TOO MUCH TIME IN TRYING TO GET BRAKING ACTION. IN RETROSPECT; IF THE SAME CIRCUMSTANCES HAPPEN AGAIN; I WILL NOT TRY TO BRAKE; SO LONG; AFTER REALIZING NO BRAKING I WOULD IMMEDIATELY GO AROUND. ALSO IF RAINING; OR AFTER RAINING; I WILL TRY TO UTILIZE THE ENTIRE LENGTH OF THE RWY AVAILABLE; IF THIS IS NOT POSSIBLE BECAUSE OF THE APCH; I WOULD DO A MISSED APCH OR CIRCLE TO LAND. RIGHT NOW I FEEL IT WAS CAUSED BY HYDROPLANING AND NOT A MECHANICAL PROB WITH THE BRAKES.
