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.

Aircraft departed Valdez, AK at 1700 l with one person on board and flew 14 miles s.e. to the head of browns creek to practice off field landings on a gravel bar at about 2000 ft MSL. After several landings, the pilot stated he was slipping the aircraft over an obstacle on the approach path and felt that the wind, which was less than ten knots in his estimation, switched from a headwind to a tailwind. The aircraft descended rapidly and struck a mound about 200 feet short of intended touchdown point. The impact with the mound damaged the main landing gear which subsequently collapsed and the aircraft came to rest on the gravel bar with substantial damage. The pilot was not injured in the accident.
