NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

THE BRAKE PADS ON THE AIRCRAFT WERE ALLOWED TO WEAR BEYOND THEIR LIMITS. WHEN THE BRAKES WERE APPLIED, THE RIGHT BRAKE CYLINDER MOVED OUT PAST ITS LIMIT AND RELEASED THE O-RING. THIS RESULTED IN A LOSS OF BRAKE FLUID FROM THE RIGHT BRAKE. ALL OF THIS HAPPENED SIMULTANEOUSLY AS THE PILOT APPLIED BRAKE PRESSURE, WHILE ON LANDING ROLLOUT. SUBSEQUENTLY, HE HAD NO RIGHT BRAKE, BUT FULL LEFT BRAKE, WHICH LEFT HIM WITH A LACK OF CONTROL OF THE AIRCRAFT WHILE ON THE GROUND. THE PILOT STEERED THE AIRCRAFT OFF THE LEFT SIDE OF THE RUNWAY ONTO ROUGH TERRAIN WHERE THE PLANE WAS DAMAGED.
