What happened
During the final phase of a training flight, the student pilot was actively manipulating the flight controls. As the aircraft approached the runway, the flight instructor recognized that the airframe had drifted off the runway centerline alignment. The instructor immediately assumed control of the aircraft in an attempt to correct the trajectory. Despite this intervention, the crew was unable to reduce the descent rate sufficiently before the landing gear struck a snowbank located adjacent to the left main wheel. The impact forces caused the aircraft to pitch forward, resulting in a nose-over attitude.
The investigation
The physical examination of the airframe confirmed significant structural damage consistent with a hard landing and subsequent ground loop or nose-over event. The point of initial contact was identified as the area near the left main landing gear, where the snowbank had been located. No mechanical failures were reported to have contributed to the loss of control prior to impact.
Findings
The primary factor in this accident was the aircraft's deviation from the runway centerline during final approach. The high sink rate at the time of impact prevented a safe landing, leading to the structural failure and nose-over. The presence of snow on the ground near the runway edge exacerbated the severity of the ground contact.
Safety message
Pilots must maintain precise lateral alignment with the runway centerline during final approach. If deviation is detected, prompt and appropriate correction is essential to ensure a safe touchdown within the available runway limits.
