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.

The aircraft returned to the airport and flew parallel to the landing runway at approximately 500 AGL until about one half mile south of the airport where it turned crosswind. It appeared the aircraft was attempting to enter a downwind for landing, however it continued to drift north and east of the airport until it impacted the ground approximately two and one half miles from the airport. The investigation at the accident site revealed the prop governor indicated it was selected to the feather position, however the propeller blades were not feathered.
