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.

During the initial updraft; the aircraft was uncontrollable, resulting in a stall/flat-spin. The engine lost power shortly after the throttle was reduced to idle.

The pilot claims he went VMC out of 1800 feet but continued the flat spin until impact. Aircraft destroyed due to collapsed landing gear, bent wings, airframe, and engine breaking off the engine mounts.
