What happened
The pilot was conducting a training flight consisting of touch-and-go landings. During one sequence, the aircraft touched down further down the runway than intended, resulting in a long landing. The pilot decided to abort the subsequent takeoff roll. At the time of the incident, wind conditions were light, blowing from 50 degrees left of the aircraft's nose at 5 knots, and the runway surface was dry. Despite these favorable weather conditions, the pilot failed to maintain directional control of the airplane during the aborted takeoff.
The investigation
Following the loss of control, the aircraft departed from the right edge of the runway pavement. Upon leaving the paved surface, the landing gear encountered snow. The impact with the snow caused the wheels to dig in, which abruptly stopped the forward momentum and resulted in the airplane flipping over onto its side or roof.
