The pilot of the ski-equipped airplane reported that during the landing on snow covered sea ice, the airplane ground looped and the left landing gear collapsed. The left wing and fuselage sustained substantial damage. The pilot added that there was an overcast cloud ceiling with light snow showers at the time of the accident, and that he attempted the landing in "flat light" conditions on "flat terrain." The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
