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.

On may 30, 2025 at the scene of the accident the pilot gave the following statement: "as I climbed the hill I realized I didnt have the altitude or airspeed to make original route over the ridge to the left so I turned toward the valley to the right and by the time I got the nose headed downhill I was too low and sinking.
