The pilot stated that the purpose of the flight was to show the airplane to two prospective buyers. According to the pilot, several minutes into the flight the engine lost power. Attempts to restart the engine failed. During the attempted forced landing, the pilot maneuvered the airplane to avoid a collision with utility lines; the airplane subsequently collided with the ground, and rested adjacent to a fence inside a pasture. The post-accident examination of the airplane at the accident site disclosed that the carburetor assembly was broken from the normally installed position. During the subsequent examination of the engine assembly, raw fuel was observed on several spark plugs, and the several cylinders displayed dark residue inside the combustion chambers. During the functional check, the engine operated normally up to 2000 RPM. A review of weather data and icing probability charts, at the approximate time of the accident disclosed that conditions were favorable for the formation of carburetor ice.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The loss of engine power for undetermined reasons. Factors were conditions favorable for the formation of carburetor ice during glide and cruise, and rough and uneven terrain.
