Narrative:THE PILOT REPORTED THAT HE WAS PERFORMING A NORMAL LANDING; THE TAIL WHEEL TOUCHED DOWN FIRST, THEN THE MAINS. DURING THE LANDING ROLL, DIRECTIONAL CONTROL WAS LOST, AND THE AIRCRAFT GROUND LOOPED. THE INVESTIGATION REVEALED THAT THE TAIL WHEEL LEAF SPRINGS HAD FAILED. THERE WAS CORROSION ON ONE OF THE FRACTURE SURFACES; HOWEVER, METALLURGICAL EXAMINATION OF THE SPRINGS REVEALED THAT ALL FRACTURES WERE FROM OVERLOAD. THE PILOT REPORTED THAT ALL OF THE LEAF SPRINGS WERE NOT LOCATED; THEREFORE, A COMPLETE METALLURGICAL STUDY WAS NOT POSSIBLE. THE AIRCRAFT TOTAL TIME WAS 26 HOURS; HOWEVER, THE LEAF SPRINGS WERE INSTALLED IN A USED CONDITION, AND THE MAINTENANCE HISTORY OF THE SPRINGS WAS NOT AVAILABLE.
Probable Cause: THE OVERLOAD FAILURE OF THE TAIL WHEEL LEAF SPRINGS, WHICH RESULTED IN A LOSS OF DIRECTIONAL CONTROL DURING THE LANDING ROLL.
