Analysis

Prior to landing, the pilot was advised that the lakes were closed by the airport management and that he would be landing at his own risk. He acknowledged the radio transmission, but elected to land his ski equipped plane on the frozen lake. The lake had been closed due to rough, rutted ice conditions which had been considered unsuitable for ski or wheel operations. The landing was normal until about 300 to 400 ft past the touchdown point where the left ski/gear encountered a diagonal rut and failed.
