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 was attempting to land at a airstrip he has never been into before. This strip is limited to highly experienced mountain pilots. His approach was high and when he was almost to the extended center line of the runway, he added power and the aircraft pitched up steeply. He continued upstream for about 1/2 mile, nose up and not climbing. The left wing dipped and the aircraft entered a spin to the left. It turned 1.25 rotations to the left as it descended and inpacted the ground.
