What happened
The pilot attempted to land on a runway that presented hazardous surface conditions due to weather. The center portion of the paved surface was covered in ice, creating a slippery zone that posed a significant risk for traction loss. To mitigate this danger, the pilot deliberately chose to touch down on the left side of the 25-foot-wide runway, where the surface appeared clear of ice.
During the rollout phase after touchdown, the right main landing gear wheel made contact with the remaining ice patch. This interaction caused the aircraft to bump and lose directional stability. The airplane subsequently veered sharply to the left. As it departed the paved surface, the left main landing gear tire entered soft grass adjacent to the runway. The force of this impact and the uneven terrain caused the nose of the aircraft to collapse forward, resulting in a nosing-over incident.
