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)While cruising, the pilot felt a 'bump,' and the engine began losing power. The pilot applied carburetor heat and adjusted the mixture control, but this action had no effect. The engine progressively lost all power until the propeller eventually just windmilled. The pilot made a forced landing in a wheat field. During rollout, the airplane encountered uneven terrain and nosed over. The pilot owned and operated the airplane. He reported that the airframe's total time was about 8,798.6 hours. The engine had been operated for 1,818.9 hours since being overhauled, and 133.4 hours since its last inspection. An examination of the engine revealed its no. 2 cylinder exhaust valve was fatigued and broken. No other engine related malfunctions were observed. (-23)while on local flight, approx. 15 min. Pilot felt a bump from engine, the engine lost power. Pilot declared an emergency with flight service and landed aircraft in a wheat field outside the town of Yuba City, CA. On touch down, the nose gear broke and the aircraft went over on it's back, causing substantial damage. Pilot was not hurt.
