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

The pilot reported that after takeoff at an altitude of 75 to 100 Feet above the ground a loss of engine power occurred. The airplane was landed in a snow covered field off the end of the runway where it contacted a ravine. An inspector from the Federal Aviation Administration examined the airplane and the inspector reported that ice was found in the fuel system, which resulted in the loss off engine power. The line leading to the fuel quick drains contained six inches of ice near the valve. The airplane had been kept outside. The left fuel tank filler cap, which was recessed, was found covered with ice.
