Chamberlin weather at the time of the accident reported a 500-foot overcast with one-half-mile visibility in moderate snow. The outside air temperature and dewpoint both indicated +1C. Freezing rain and snow were observed in the vicinity of the airport the previous afternoon and overnight before the accident flight. The airplane was not stored inside a hangar the night before the accident. Flying’s phone calls to the Chamberlin Airport to determine if a suitable hangar might have been available that night were not returned. The NTSB said witnesses reported the pilot and a passenger worked for three hours to remove the snow and ice from the airplane before the accident flight. The pilot contacted Minneapolis Center for his IFR clearance to the destination airport—Idaho Falls, Idaho—while still on the ground at Chamberlin. However, there was no radio or radar contact between the aircraft and ATC once the aircraft departed.
