The pilot's attempt to continue the takeoff with a partial loss of power. Contributing to the accident were the carburetor icing conditions.

Analysis

A partial loss of power was experienced at about lift-off. The pilot continued the takeoff and applied carburetor heat which worsened the power loss. A forced landing was made in a plowed field during which the airplane was substantially damaged. Examination of the engine revealed no mechanical failure or malfunction, nor contamination of the fuel. Meteorological conditions were favorable for carburetor icing. The temperature was 42 degrees f, and the dew point was 27 degrees f. the pilot did not obtain a weather briefing prior to the flight.
