NTSB Narrative Summary Released at Completion of Accident

According to the pilot, during his landing on runway 25, the aircraft bounced slightly and then touched down "normally," but during the landing roll, the left main wheel structure collapsed and the aircraft nosed over onto its top wing. This scenario was confirmed by a witness who was working near the runway and who had seen the aircraft land. An inspection of the wheel disclosed that all but three wire spokes had pulled out of the wheel rim. The pilot said that he had not noticed any loose spokes prior to takeoff, but that the grass strip he departed from was "pretty rough." The reason for the separation of the spokes from the wheel rim was not positively determined.

NTSB Probable Cause Narrative

The collapse, for undetermined reasons, of the left main landing gear spoked-wheel structure.
