Investigator assessment
Analysis narrative
While landing a wheel/ski-equipped airplane on a snow and ice-covered runway, after touchdown, the airplane began to slide to the right side of the runway. The pilot reported that the edge of a ski impacted a lip of ice which caused the airplane to nose down, and the right wing subsequently struck the ground, resulting in substantial damage. The pilot reported that there were no pre-accident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
