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) The pilot performed the normal before takeoff checks. He said the engine was running smooth, and both mags checked good then lined up on the center of the strip, heading to the north, and brought the power up to 35 inches of manifold pressure and 2300 RPM. The aircraft accelerated normally and lifted off at about 70 mph. The then stated he felt a loss of power and the aircraft settled back onto the runway. The aircraft struck a fence and an incline at the departure end of the grass strip which launched the airplane back in the air for about 150 yards. The aricraft then impacted the ground in a three point attitude, and the main tires dug into the mud in the bean field, and the aircraft flipped to an inverted position facing the opposite directon of takeoff. The investigation revealed the aircraft had fuel, performance limits were not exceeded and the fact of only one of the propeller blades was bent back indicate the engine was not developing power at the initial impact in the bean field.
