Incident Overview
A solo student pilot completed two full stop landings without incident, though both rollouts were accompanied by a slight nosewheel shimmy. During the third full stop landing, shortly after touchdown on the 5,000-foot by 100-foot runway, directional control was lost. The aircraft veered left, departed the runway, and collided with a ditch on the north side, where it came to rest.
Environmental Conditions
Winds were from the northeast at 10 knots at the time of the incident. The runway was dry (assumed, though not explicitly stated, but no mention of wet conditions).
Pilot Report
According to the pilot, the first two landings were uneventful except for a slight nosewheel shimmy during the rollout. On the third landing, a violent uncontrollable left turn occurred, leading to the loss of directional control. The pilot was the sole occupant and was a student pilot flying solo.
