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.

Pilot was spraying corn when he saw a puff of smoke from the engine. He ceased spraying and gained altitude to assess the situation. He then witnessed additional puffs of smoke form the engine and began losing manifold pressure. He dumped his chemical load and made an emergency landing in the corn, subsequently flipping the aircraft over (tail over nose).
