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.

Pilots departed South Valley Regional Airport (KU42). The aircraft climbed and reached FL058 15:41:28Z. The aircraft remained between FL058 and FL060 at speeds near 100KTS until radar was lost at 15:47:20Z. Trooper watkins, also a private pilot, while driving on the canyon road observed the aircraft well below him at an estimated 200-300 feet above the terrain at nearly a 90 degree angle with the nose down at a very slow airspeed. The aircraft stalled, entered a spin to the right, and impacted the ground at 7,352 feet MSL, nearly 2,000 feet below the ridge line at an elevation of 9,370 feet.
