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.

Aircraft engine lost power and pilot made emergency landing in a bean field. (.4)the pilot reported he was cruising at 3,300 feet mean sea level. All gauges were 'normal.' He heard a 'loud back fire' and the engine lost power. He pushed the throttle, mixture and propeller control full forward. The engine continued to run at 'idle speed.' During the subsequent forced landing, he landed with 'low airspeed and high sink rate.' The landing gear collapsed and the engine was bent downward. Examination of the engine revealed several spark plugs and the top of the pistons were oil covered. Several spark plugs 'appeared to have been running rich.' There was 'a lot of oil in the plenum chamber' and the supercharger blades had 'excessive rub on the rear face.'
