Analysis

Shortly after leveling at the cruise altitude of 2500 ft, the pilot noted a gradual RPM decrease and resultant loss of power. Altitude could not be maintained and the pilot selected a rolling open field in which to land when he realized that reaching an airport seven miles south was improbable. During the landing roll a steep incline was encountered that collapsed the nose gear and the acft slid. The temperature and dew point indicated that conditions wereconducive to the formation of carburetor ice. The plt stated that he did not apply carb heat because he felt that list in the pilot's operating handbook does not include the application of carb heat. The engine was later run successfully in a test cell with no discrepancies noted.
