What happened
The flight was initially destined for an airport where weather conditions deteriorated significantly. Due to low clouds and reduced visibility at the destination, the pilot made the decision to divert to a local air park instead.
While maneuvering in the pattern to land at this alternate location, the pilot observed that the runway surface was covered in snow. Despite the coverage, visual references were available; vegetation could be seen through the snowpack, and bare ground was visible where snowmobiles had previously made several turns, indicating some level of surface firmness.
During the final phase of the landing roll, the aircraft's main landing gear encountered deep snow that offered insufficient support. The wheels sank into the accumulation, causing the nose of the airplane to pitch downward violently. This nosing-over event resulted in substantial damage to the airframe.
