What happened
During the initial phase of an instrument approach to the destination airport, the airplane was in visual meteorological conditions above clouds that contained reported icing conditions. Prior to and during the approach, the air traffic controller, who was vectoring the airplane, advised the pilot of two pilot reports of icing conditions encountered immediately after departure. The airplane entered the clouds at 8,500 feet and reported a missed approach several feet above the decision altitude; the pilot did not report any problems or declare an emergency. No further radio communications were recorded. The wreckage was located on the airport, about 440 feet south of the approach end of the runway. The ground scars and damage to the airplane were consistent with a low-airspeed and high-angle-of-attack impact. Instrument flight rules (IFR) conditions existed over the area with conditions favorable for icing below 8,500 feet. AIRMET advisories for IFR, mountain obscuration, turbulence, and icing conditions had been issued. At the time of the accident, visibility was reported as less than 1/4 mile in freezing fog, with a ceiling at 100 feet. The approach minimums were 200-foot ceilings and 1/2 mile visibility. The airplane was not equipped with anti-icing or deicing equipment and was not approved for flight in known icing conditions.
