Analysis

The pilot reported that the carburetor heat control became inoperative while on a cross-country flight. The weather conditions were conducive to the formation of carburetor ice. A decision was made to land in an alfalfa field while the engine was still operative. One pass was made over the intended landing area. During a go-around and a pattern for landing, the engine lost all power. The pilot was unable to glide to the intended landing area and crash landed in the only available open field.
