Read the full NTSB narrative

AFTER LANDING ON THE GRAVEL BAR ON THE ROBERTSON RIVER, THE LEFT WHEEL'S BRAKE 'WENT SOFT.' THE PILOT ALLOWED THE AIRPLANE TO CONTINUE THE LANDING ROLL AND PRIOR TO STRIKING THE DITCH, HE INTENTIONALLY GROUND LOOPED THE AIRPLANE. DURING THE GROUND LOOP THE TAIL WHEEL STRUCK THE DITCH AND THE FUSELAGE BUCKLED. EXAMINATION OF THE AIRPLANE SHOWED THAT THE LEFT BRAKE'S TORQUE PLATE HAD SHEARED AND BROKEN THE BRAKE LINE.
