PVT PLT OF A C172 LOST CTL OF ACFT DURING LNDG ROLL AND WENT OFF END OF RWY.

Narrative

FLT DEPARTED TRM AT XC15 APR/XA/01 DIRECT TO L54. WX GOOD; 10+ MI VISIBILITY; WIND CALM; SKY CLR; TEMP 30 DEGS C; ALTIMETER 30.00. ARRIVED AT DEST APPROX XC45. NO INFO AVAILABLE FOR L54; BUT WINDSOCK INDICATING RWY 11 AS ACTIVE. STANDARD 45 DEG ENTRY L TFC FOR RWY 11; NO OTHER TFC IN AREA. WENT AROUND FIRST TIME; APCH APPEARED HIGH. CONTINUED WITH STANDARD L TFC PATTERN; ACFT SET UP FOR STANDARD APCH SPD (60-65 KTS). TOUCHDOWN OCCURRED AT AROUND 50 KTS FIRST HALF OF RWY AND NORMAL BRAKING WAS APPLIED. BRAKES APPEARED TO FADE NOT BRINGING ACFT TO STOP. AT THIS POINT PAX PLT ASKED IF I WAS GOING TO STOP; TO WHICH I REPLIED I WAS BRAKING WITH NO EFFECT AND REQUESTED HE ASSIST; AS AT THIS POINT THERE WAS INSUFFICIENT AIRSPD AND RWY TO EFFECT A SAFE GAR. WITH BOTH PLTS ON BRAKES; THEY APPEARED TO LOCK UP AND ACFT CONTINUED TO END OF RWY. WITH NO OTHER OPTIONS AVAILABLE TO ME; I PULLED MIXTURE TO SHUTOFF; HELD YOKE BACK SO AS TO AVOID PROP STRIKE AND PROTECT NOSE GEAR; ACFT LEFT RWY AND CAME TO A STOP AS WHEELS DUG IN (VERY SOFT SANDY GND). AS ACFT CAME TO A STOP IT SWUNG TO L CAUSING R WINGTIP TO STRIKE GND. AT THAT POINT ALL SYS WERE SHUT DOWN AND FUEL LEVER SET TO OFF. BOTH PLTS VACATED ACFT SHAKEN BUT NOT INJURED. FACTORS THAT MAY HAVE CONTRIBUTED TO INCIDENT ARE THAT PLT HAD ONLY 2.5 HRS IN THIS ACFT IN THE LAST 90 DAYS; SHORT RWY WITH ZERO HEADWIND; 3000 FT DENSITY ALT AND 30 YR OLD ACFT.
