What happened
The incident occurred during a training flight involving repeated touch-and-go landings. After completing a landing and beginning the rollout phase, the student pilot diverted his attention downward inside the cockpit to adjust the aircraft's configuration for the subsequent takeoff.
Upon looking back up at the runway environment, the pilot observed that the airplane had drifted slightly to the right of the runway centerline. In an attempt to correct the deviation, he applied left rudder input. However, the aircraft continued to drift further to the right despite these corrective efforts.
The airplane eventually departed the west side of the paved surface and struck a ditch. The impact caused the nose gear to collapse, resulting in a nose-over attitude for the aircraft.
The investigation
Examination of the accident site revealed that the airplane had left the runway pavement on the western side. The damage was consistent with striking a ground depression or ditch immediately adjacent to the runway edge. No mechanical failures were reported as contributing factors to the loss of directional control during the rollout.
Findings
The primary factor in this accident was the pilot's failure to maintain proper aircraft control during the critical transition phase between landing and takeoff. Specifically, the pilot allowed the airplane to drift off the runway centerline while distracted by cockpit tasks. The subsequent inadequate correction for the lateral deviation led to the departure from the runway surface.
