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 pilot initially requested lower and was assigned FL350. The pilot did not declare an emergency, but notified the controller that he had lost an engine and was going down. The controller declared an emergency for N430JW. During descent IFR separation was lost between N430JW and an Alaska airlines flight.
