Analysis

The acft crashed into a mountain at the 12000 ft level in bad weather during a cross-country flt. Before takeoff the pilot had been advised of adverse weather enroute with VFR flt not recommended. He said he would fly out to check the weather and return if it was too bad. Later he called aspen for a'fix' or aid in returning and was told he would have tocall denver. A local resident heard the pilot trying to call denver but contact was never made. Sometime later an flt signal was reported. The acrt was found the following day in a snow covered wilderness area near leadvlle co.
