The pilot of the tail wheel equipped airplane reported that, while conducting a full stop landing, the airplane touched down normally. He felt a jolt then the airplane started to veer towards the right side of the runway and nosed over. The airplane came to rest inverted, which resulted in substantial damage to the wings and vertical stabilizer. The left main wheel separated from the landing gear strut near the wheel attachment during the landing. The landing gear strut was bent inward. Photographs of the landing gear strut fracture surfaces were sent to the NTSB Material Laboratory for further review. The specialist reported that the fracture appeared to be due to overstress. No fatigue crack origin area was identified. The pilot reported that there were no other mechanical failures or malfunctions with the airplane that would have precluded normal operation.
