Event Description
The aircraft had recently undergone an annual inspection. Before departing on a local flight, the fuel tanks were topped off. The pilot reported that the preflight run-up was satisfactory, and during the takeoff roll, the engine developed full power. Shortly after takeoff, however, a partial loss of power occurred.
Pilot Actions
The pilot checked the magnetos and mixture but did not apply carburetor heat. The engine power continued to deteriorate.
Forced Landing
During a forced landing in a pasture-type field, the right wing struck the base of a silo.
Post-Accident Examination
An examination of the engine and fuel system revealed no discrepancies that would have resulted in a power loss.
Weather Conditions
The temperature was 76°F and the dew point was 61°F. According to icing probability charts, visible icing could occur in float-type carburetors at rated power, and serious icing could occur at glide power.
