Analysis

The acft experienced a loss of pwr in the rt eng immediately aft tkof. The plt was not able to feather the propeller and was forced to land in a wheat field on arpt property. Conditions were conducive to carburetor icing at the time of the accd. Investigation revealed that the rt propeller hub was improperly assembled and would not allow the propeller to feather. In addition, the rt carburetor heat system was inoperative because the ducts that connect the manifold heat muffs to the carburetor air box were missing.
