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.

Acft was departig private strip when acft lost lift. Pilot dumped most of the liquid fertilizer but crashed in sage brush. (-23) pilot had been spreading fertilizer all morning using what was believed to be 1150 lbs in the hopper of the aircraft. He had made six trips at this weight prior to the accident. He had noticed the aircraft had felt heavy the last couple of loads so he cut the weight down to an estimated 1050 lbs. When he took off on the last flight, the aircraft would not climb out of ground effect and flew into rising terrain in the form of rolling hills. Field elevation was 4000 feet and temperature was 64 degrees fahrenheit. Pilot had very little experience in operating the aircraft. He experienced difficulty in operating the dump valve when he realized he was not going to clear the terrain near the end of the runway. A safety recommendation will be filed in regard to this problem.
