During a WX briefing the pilot was briefed that a cold front WX system was moving through the route of flight, with moderate icing in clouds to 16000 ft. The pilot had to return to the ramp after taxiing to takeoff due to a dead battery. As the battery was being recharged, the pilot reportedly seemed apprehensive about the WX conditions and told the mechanic to feel free to write up any discrepancy that would cancel the flight. The pilot also stated he didn't like flying in the kind of weather that was in the area. About 50 minutes after departure that pilot radioed that he was in serious trouble. No further communications were received. The wreckage was located in an area of steep mountainous terrain that rises to over 9000 ft MSL. Evidence showed that the wings and stabilators separated prior to ground impact. Leading edge surfaces of the airplane exhibited pitting and abrasion of paint, with areas of paint stripped down to bare metal. Blizzard weather conditions existed at the time.
