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.

Pilot operated aircraft in VMC conditions conducive to induction icing for approximately 1-1/2 hours. As pilot was preparing for final approach to Falmouth airpark, pilot selected carb heat. On selecting carb heat, the engine RPM fluctuated. Pilot immediately de-selected carb heat and the engine quit operating. Due to the aircraft's low altitude, pilot accomplished limited troubleshooting before preparing for an emergency landing. Options were a populated beach, trees, or water. Pilot elected to land approximately 30 yards offshore of south cape beach. A post-accident engine inspection did not show any failed engine components.
