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) On 8/30/2006, at approx. 1755 local, approx. 5 miles south of glenndale airport (8I3), N22523, a Cessna 150H, made an off-airport landing due to engine power loss. The instructor had been providing private pilot training to the student and returning to 8I3 for landing, when the engine began to lose power. The instructor, suspecting carb. Ice, applied carb. Heat. The engine began to shake violently, so he leaned the mixture, which was no help. The engine continued to lose power. An off-airport emergency landing was made, with the aircraft ending up inverted, nose pointing approx. 290 degrees, IN a soybean field, with minor injury to the instructor and no injury to the student. The fuselage bottom was covered with engine oil. The oil drain plug was missing from the oil sump and less than 2 pints of oil was recovered from the engine. Suspect the oil drain plug was improperly torqued, then not safetied, allowing the plug to loosen over time, until it fell out, letting the oil drain out, causing the engine to overheat (evidenced by heat discolored cylinders), and premature ignition (detonation) occurred, leading to loss of engine power, which the pilot believed was due to carb. Ice.
