THE PILOT STATED THAT ON HIS LAST APPROACH, THE SPEED WAS TOO FAST, THE AIRCRAFT BOUNCED AND HE OVERCONTROLLED CAUSING THE PROPELLER TO STRIKE THE RUNWAY. THE AIRCRAFT NOSED OVER AND CAME TO REST ON IT'S BACK. THE PILOT ALSO STATED THAT THERE WERE NO MECHANICAL FAILURES OR MALFUNCTIONS PRIOR TO THE ACCIDENT.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
