Narrative:
THE PILOT WAS COMPLETING A VFR PERSONAL FLIGHT IN A CONVENTIONAL GEAR AIRPLANE. ON LANDING, THE AIRPLANE BOUNCED AND CONTINUED TO PORPOISE, GROUND LOOPED, AND EXITED THE RIGHT SIDE OF THE RUNWAY. THE PILOT TOLD A GROUND WITNESS THAT SHE MESSED UP THE LANDING. THE PILOT REPORTED IN THE ACCIDENT REPORT THAT THE RIGHT LANDING GEAR WHEEL 'LOCKED UP.' EXAMINATION OF THE BRAKES, TIRES, AND FLIGHT CONTROL SYSTEMS REVEALED THAT THEY WERE IN GOOD CONDITION. HOWEVER,THE AIRPLANE CROSSWIND LANDING GEAR DETENT STOP AND SNUBBER PIN WERE WORN. THIS CONDITION ALLOWED THE LEFT WHEEL TO UNLOCK PREMATURELY AND WITHOUT WARNING.

Probable Cause: the pilot's improper recovery from a bounced landing. The mechanic's inadequate annual inspection by failing to determine the worn condition of the crosswind landing gear detent stop groove and snubber pin and the soft terrain were factors in this accident.
