What happened
The pilot was conducting an attempted takeoff operation under winter conditions where significant snow accumulation was present on the airfield. During the initial phase of the ground roll, the aircraft accelerated down the runway. The pilot managed to reach a distance of approximately 1,000 feet from the start of the takeoff run. At this point, the aircraft had achieved a ground speed of 45 knots.
As the acceleration continued, the left main landing gear encountered a snowbank situated along the edge or within the runway environment. The impact with the accumulated snow caused an immediate loss of directional control. The force of the strike resulted in the aircraft nosing over, leaving it in an inverted position on the ground.
The investigation
Examination of the event focused on the interaction between the landing gear and the winter weather conditions. The primary mechanical factor identified was the left main gear striking a snowbank during the high-speed ground roll. This obstruction prevented the pilot from maintaining control of the aircraft's trajectory as it attempted to become airborne.
