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.
Aircraft experienced a rough running engine in cruise flight (11,000 feet). After approximately 20 seconds, the engine quit and the pilot made an emergency landing. Removal of the cowling revealed both rear pistons had broken through the crankcase. In addition, several connecting rod pieces were lying on the top of the engine case.
