What happened
The pilot taxied the aircraft to a runway covered in snow to begin the departure sequence. After completing a standard run-up check of the engines, the pilot moved onto the active runway and initiated the takeoff roll. The airplane accelerated normally along the surface until it reached approximately 80 knots of airspeed. At that point, the aircraft veered sharply to the left side. It subsequently departed the paved surface and collided with a nearby snow bank. The impact resulted in substantial damage to the airframe.
The investigation
Following the accident, investigators examined the circumstances surrounding the departure. The pilot stated that there were no mechanical malfunctions or system failures reported prior to the event. No other mechanical issues were identified that would have contributed to the loss of directional control during the roll.
