Analysis

The pilot reported that while he was spraying crops, the engine began to skip and backfire. He decided to terminate the swath run and climb from the field. At that time, the engine quit and the pilot climbed as high as possible before gliding to a nearby soybean field. During the landing phase, the aircraft was damaged. An investigation revealed that the carburetor heat ducting was disconnected, thus rendering it inoperative. The nearest weather reporting facility reported that the temperature and dew point were 86 and 70 degrees, respectively. According to icing probability charts, conditions were conducive to serious carburetor icing at glide power and visible icing at cruise power.
