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.

Acft crashed under unknown circumstances while enroute to a hunting camp 20 miles east of galbraith lake, the wreckage was located inverted and burned, the pilot/sole occupant suffered fatal injuries, other circumstances are unknown. (-23)it appears from the investigationof the accident scene, that the a/c stalled then spun into the ground while trying to reverse course in a narrowvalley. Statements from an employee do not indicate weather or overloading as factors. The pilot had experience flying in this area. All control surfaces were attached and functional. The engine was developing power on impact. (.4) the flight had departed a remote hunting camp, about 25 miles north of the accident site, to locate sheep prior to dropping off the passenger. The flight was reported overdue to the Alaska state troopers, and an aerial search located the wreckage the following day. Visual meteorological conditions prevailed at the nearest reporting station, 60 miles south of the accident site, at the time of the accident. One of the pilot's employees told th e NTSB investigator-in-charge (iic) the winds at camp were calm, there were some clouds visible to the south, and the tops of the mountains were visible toward the accident site. The airplane struck terrain in a near vertical attitude, and came to rest inverted in the bottom of a box canyon. The empennage was rotated and twisted to the right. A postcrash fire consumed both fuel tanks, and the fuselage. Postaccident examination of the airplane and engine revealed no preaccident anomalies.
