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.

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

His route of flight took him up channeled, mountainous terrain requiring a climb to a minimum of 9,000 feet MSL. Winds aloft were forecast to be between 28 and 41 knots. Surface winds were forecast to be in a downslope direction at 25 knots gusting to 50 knots from channeled terrain. Cessna 172 performance charts for the 180 horsepower engine indicate a maximum climb rate available of 405 feet per minute at 8,000 feet pressure altitude. Ceilings of 8,500 feet were reported on the west side of the mountains. The pilot radioed that he was going to try to get on top through a hole. The airplane was located on the west side of a peak, in deep snow, at 8,600 feet MSL. About 40 hours after the departure. The emergency locator transmitter signal was masked by terrain and wreckage. Both occupants were lightly dressed, and appeared to have survived the impact. The pilot was described by acquaintances as inexperienced and prone to taking chances with the airplane.
