BOLIVAR, MO, USA
N793DB
Baker FISHER HORIZON
The pilot reported that after about 20 to 30 minutes of flying the engine began to lose power. He checked the magnetos, added carburetor heat, and changed throttle settings, but it did not restore engine power. The pilot said that he executed a forced landing into a field but it was too short and the airplane struck a fence. The pilot reported that he thought the 'engine problem was caused by carburetor ice. Flying at 1,000 feet there was not enough time for the carburetor heat to clear the ice.' The temperature was 44 degrees Fahrenheit and the dew point was 34 degrees Fahrenheit. According to a carburetor icing probability chart, the conditions were conducive for carburetor icing.
