## Analysis

DURING LANDING, THE AIRCRAFT TOUCHED DOWN ABOUT 1/3 OF THE WAY DOWN THE RUNWAY. THE PILOT REPORTED THAT AFTER TOUCHDOWN, HE APPLIED THE BRAKES INTERMITTENTLY, BUT THERE WAS LITTLE EFFECT ON THE DRY, HARD, GRASSY SURFACE. WHEN IT BECAME APPARENT THAT HE WOULD BE UNABLE TO STOP ON THE RUNWAY BY USING NORMAL BRAKING, HE ATTEMPTED TO INTENTIONALLY GROUND LOOP THE PLANE. HE CLAIMED THAT THE RIGHT BRAKE LINE BURST. THE AIRCRAFT CONTINUED THROUGH A BARBED WIRE FENCE, CROSSED A NARROW ROAD AND WENT INTO A FIELD OF TALL GOLDENROD WHERE THE WHEELS BECAME ENTANGLED AND THE AIRCRAFT TURNED OVER.
