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) After departure, at 300-400 ft AGL, the pilot reported a loss of power. Witnesses reported a normal t-o roll followed by a steep climb angle on departure. Soon after departure, witnesses heard the engine noise change from normal to quiet and a series of popping noises like a "backfire". The pilot attempted to return to the runway and collided with terrain near the airport. Aircraft hit hard nose first and overturned. There was a post impact fire. Inspection of the powerplant and systems did not reveal any indications to support the loss of power. The acft was fueled to capacity on 07/02/01. Fuel availiable and onboard the aircraft at the time of the accident can not be verified. A lake expert stated that low fuel status in the center tank with steep climb out angles can "unport" the fuel flow to the engine.
