The pilot reported a gradual loss of engine power during cruise flight. He applied carburetor heat when the engine began running rough, which seemed to make the situation worse. Eventually, the available engine power was insufficient to maintain altitude and it became clear the airplane would not be able to reach the destination airport. The pilot executed a forced landing to a field; however, he flared too high and landed hard. The airframe sustained substantial damage to both wings and the fuselage.
A postaccident engine examination revealed minor anomalies with respect to the carburetor heat system, and those anomalies may have slightly reduced the effectiveness of the carburetor heat when applied. The remaining anomalies identified during the engine examination were not consistent with a gradual loss of engine power and did not contribute to the accident.
Meteorological conditions were conducive to the formation of carburetor icing during cruise flight. Based on the available information, it is likely that the formation of carburetor icing, which the carburetor heat system was unable to adequately remove, resulted in the loss of engine power. In addition, the hard landing that occurred during the forced landing may have increased the extent of damage to the airframe.
Probable Cause: A partial loss of engine power due to the formation of carburetor ice, which resulted in the inability to maintain altitude and the subsequent hard forced landing.
