Analysis

The acft crashed in an open field during an uncontrolled descent after encountering forecast icing conditions. The plt had received weather briefings and filed a flt plan into icing conditions in an acft not equipped to handle icing. The plt stayed at an icing level for about 19 minutes, 6 minutes of which were with heavy icing accumulating at the rate of about 2 inches per minute. At this time the acft was too heavy to climb and during descent, control was lost and the acft crashed.
