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.

(.4)The pilot and a passenger were in cruise flight in a tailwheel equipped airplane. About one hour after departure, the engine oil pressure began to decrease to below the normal operating range. The pilot began a climb to 3,500 feet mean sea level. The engine then began to run rough, and the pilot shut the engine off. The pilot performed an emergency landing in a small open area that had previously been used as a landing area. The airplane touched down in snow covered terrain, and then nosed over. The airplane received damage to the left wing spar, the rudder, and the leading edge of both wings. An examination of the airplane engine revealed the number six piston connecting rod bearing, and the connecting rod cap, were destroyed. The number six crankshaft rod bearing journal was blackened and battered. (-23) during cruise at 1500 ft, the pilot noticed engine oil pressure fluctuating and dropping. The pilot climbed to 3000 ft and shut the engine off because of vibration. The pilot was able to glide to a short snow covered runway and landed then went upside down. No injuries.
