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.

Pilot approached san andreas airport (cpu) for a landing on runway 31. At the time of the landing one witness states the winds were squirly and gusty but the pilot states there were no unusual wind conditions. The pilot states that he touched down at 80 mph then for unknown reasons the front bounced twice and the nose gear collapsed causing the propeller to strike the runway and the aircraft exited to the right into the grass area between the runway and the taxiway. Examination of the nose gear assembly including the tire and rim suggest that a side load from the right side was excerted to the tire and rim causing the tire to burst and the rim to get fractured. The force twisted and cracked the nose gear fork and caused the nose gear to collapse.
