## Analysis

AFTER MAKING 2 GO-AROUNDS, A LANDING WAS MADE ON THE 3RD APCH. THE PLT REPORTED THAT THE BRAKING WAS POOR TO NIL. BY THE TIME HE CRESTED THE TOP OF A HIGH POINT ON THE RWY, HE REALIZED THAT THERE WAS INSUFFICIENT ROOM REMAINING TO GO AROUND OR STOP ON THE LANDING AREA. THE ACFT CONTINUED OFF THE RWY & WENT INTO A RAVINE. THE PLT ESTIMATED THE WIND WAS FROM THE SOUTH SOUTHWEST AT 18, GUSTING 21 KTS. AT MADISON, WI, THE 0800 CDT WIND WAS FROM 180 DEG AT 16 KTS.
