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.

(-23) At 16:35 local, aircraft 28JP, a Beech 36A, crash landed in a wheat field located in nassawadox, Virginia. Aircraft was enroute to 33N at 3500 feet VFR. Pilot contacted orf tower and reported engine trouble, and that he was going to land at mfv. Orf lost radio contact and aircraft disappeared from radar. Witnesses reported seeing fire as the aircraft went down. Aircraft crashed about 20 miles short of mfv. (.4) approximately 50 minutes after departure, during a cross-country flight, the airplane's engine began to run rough. The pilot noticed the oil pressure had decreased, he heard a loud 'bang', and the engine experienced a total loss of engine power. He was unable to maintain the airplane's altitude, and performed a forced landing to a field. Examination of the #2 piston revealed a hole from detonation on the side of the piston, which extended into the interior. Advisory circular AC65-12A stated that detonation can burn a hole completely through a piston. Examination of the crankshaft revealed a lack of lubrication and severe overheating. The #5 and #6 connected rods had separated from the crankshaft, and their bearings were completely disi ntegrated.
