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) Weather at the time of the accident was low overcast and snow with winds 090@11G26. The takeoff roll on runway 16 was normal until at a speed of approximately 70-75 KTS, when the left engine began to surge. The pilot confirmed the surging engine was the left engine by use of engine instruments. The pilot attempted to regain control of the engine and directional control of the aircraft by retarding the left engine power lever slightly, (1 inch). The left engine continued to surge and directional control of the aircraft was compromised. An abort of the takeoff was initiated. During the abort of the takeoff, the aircraft drifted left until the left main gear departed the runway sinking in the soft ground causing further deviation to the left until all gear were off the runway. The aircraft impacted a runway sign causing the nose gear to collapse before the aircraft came to rest. There was no injuries.
