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) Aircraft departed runway 24, experienced a loss of power and was unable to maintain airspeed. The aircraft clipped powerlines and came to rest in a wooded area adjacent to a cornfield near listie road. The pilot and one occupant were not injured. The aircraft sustained substantial damage. The aircraft and the engine were inspected at the accident site. The carburetor was checked and found that the accelerator pump would not move and the throttle valve would only move approximately 30% of travel. The compression for each cylinder was checked #3 was very low and #5 had none at all. The carburetor was removed and inspected. It was determined that the accelerator pump was frozen in its bore and that was the reason the throttle valve would only move 30%. The air cleaner was plugged with dirt.
