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.

The aircraft was climbing through 3500 feet when the engine experienced a loss of power and decrease in RPM of approximately 200. The pilot elected to return to his home airport which was 3 miles away. The engine was running and responsive to throttle inputs. The pilot entered a normal traffic pattern and when turning to the base leg he realized the aircraft was too low. The pilot added power but the response from the engine was insufficient to check the descent. The aircraft hit the ground approximately 500 feet short of the displaced threshold of the runway 31. It remained upright and there was no post-crash fire.
