The NTSB's narrative final · quoted from the NTSB record

The pilot, a licensed aviation mechanic, had just installed wheel penetration skis on the main landing gear of his personal airplane. During a subsequent test flight, the skis immediately rotated nose up to a near vertical position. The pilot continued around the traffic pattern, and landed in snow just prior to the start of the runway. The skis failed to come out of the near vertical position, and during the landing roll, one ski broke off, causing the gear leg to penetrate the snow, which allowed the right wing and elevator to strike the snow. Postaccident examination of the skis disclosed the ski check cables at the heel of the skis were excessively long.
