Aircraft involved
Probable cause & findings
The pilot's decision to execute a precautionary landing to unsuitable terrain.
Factual narrative
The pilot reported that the engine began to lose power during cruise flight. He applied carburetor heat and engine power was restored. Approximately 5 minutes later, the engine again began to lose power. The pilot applied carburetor heat and the engine power increased; however, the pilot was concerned the engine was not developing full power. He elected to make a precautionary landing on a road, but during the landing approach he noted power lines and a fence bordering the road. The pilot decided the road was not suitable for landing. Concerned that the engine was not performing well enough to execute a go-around, the pilot elected to continue the landing into a nearby cornfield. The airplane contacted the corn crop, a ditch, and a fence during the landing resulting in substantial damage to the wings and firewall. According to the Federal Aviation Administration icing probability chart, with the temperature and dew point, 84 degrees Fahrenheit and 75 degrees Fahrenheit respectively, conditions were conducive for carburetor ice at glide and cruise power. The pilot applied carburetor heat twice during the flight to regain engine power. Following the second application of carburetor heat, he was not confident that the engine was producing full power and he elected to make a precautionary landing on a road; however, during the landing approach he noted power lines and a fence bordering the road. The pilot decided the road was not suitable for landing. Concerned that the engine was not performing well enough to execute a go-around, the pilot elected to continue the landing into a nearby cornfield. The airplane contacted the corn crop, a ditch, and a fence during the landing resulting in substantial damage to the wings and firewall. According to the Federal Aviation Administration icing probability chart, the airplane was operating in conditions conducive to carburetor icing at glide and cruise power at the time of the accident.
