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 reported leaving home airport (12CL) on a post maintenance flight around the home airport. Maintenance had been done on the window/door latch, (it had been coming open in flight.) During maneuvering near the landing strip the engine started to surge 2-3 times then lost power completely. The pilot elected to land straight ahead rather than to risk a 180 degree turn to the runway. The aircraft landed in a cultivated field which was very soft. The main wheels dug in as the aircraft slowed down causing it to flip over damaging the propeller, engine wings and tail. The pilot was not injured.
