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 maintenacne check flight required the pilot to shut down each engine individually. Approximately 5-10 seconds after shutting down the left engine, smoke appeared from beneath the switch panel left of the pilot's seat. Partial electrical system failures that included landing gear and flaps extension being inop was expeerienced by the pilot. Emergency landing gear extension procedures were followed and an emergency was declared by the pilot to the ted Stevens international airport tower. Pilot attempted to restart the lt engine without success. A succesful single engine, no-flap landing was accomplished.
