Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

The pilot's selection of unsuitable terrain for landing. Contributing factors were the pilot's lack of total experience, and the snow covered runway.

Analysis

The student pilot and his passenger were attempting to land on a snow covered runway at Cantwell, AK. The wheel equipped airplane encountered deep snow during the landing roll, causing the left main landing gear to collapse. The student pilot had a total of 49.2 hours of flight experience, and was prohibited from carrying passengers.
