From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Crashed on landing, other circumstances unknown. (.4)the airplane departed a rough, rocky, gravel bar. During the subsequent landing roll at the pilot's gravel strip, the plane veered to the right. As the plane decelerated, full left rudder and brake input by the pilot did not maintain directional control. The airplane departed the right side of the strip, the left main landing gear separated, and the airplane nosed over. Inspection revealed that the right main landing gear was canted ten degrees to the right, and had been installed using 'cherry max' rivets instead of the required solid rivets.
