What happened
The pilot initiated a landing procedure under crosswind conditions that ultimately proved beyond his operational capabilities. Prior to the event, the pilot had indicated an intention to divert to an alternative airport if the crosswind component became excessive; however, he proceeded with the approach at the original location. Upon touchdown, the aircraft drifted laterally to the right, departing the paved surface and impacting a snow bank situated two feet high along the right side of the runway. The impact caused the propeller to strike the snow bank, resulting in the aircraft rocking onto its left wing.
The investigation
The physical evidence indicated that the aircraft sustained damage consistent with an off-runway landing. The primary mechanical interaction involved the propeller striking a stationary snow bank adjacent to the runway edge. The force of this impact caused the aircraft to roll onto its left wing, confirming the lateral drift observed during the landing phase.
Findings
The sequence of events was driven by the pilot's decision to continue the landing despite crosswind conditions that exceeded his ability to maintain directional control. The failure to divert earlier, combined with the inability to keep the aircraft aligned with the runway centerline, led directly to the off-runway excursion. The presence of a snow bank on the side of the runway contributed to the severity of the impact when the aircraft drifted right.
Safety message
Pilots must accurately assess their personal crosswind limitations and adhere strictly to diversion criteria before reaching critical phases of flight. Continuing an approach in conditions that exceed one's capability significantly increases the risk of loss of control and off-runway incidents.
