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 N73100, a Cessna CE-207 departed Deadhorse A1L at approximately 1900AKDT. Pilot noticed that the engine began to leak oil and turned aircraft back towards Deadhorse AK. One mile from the airport the oil pressure dropped and the engine began to overspeed, then the propeller separated from the aircraft. The separation was caused by the cranshaft failing just aft at the flange. Pilot landed without further incident.
