NTSB narrative

The private pilot and passenger were on a local area personal flight in the single-engine airplane. The pilot reported after flying for 20 minutes, he was at 1,500 ft mean sea level when the airplane began to lose engine power and he was unable to maintain altitude. The pilot added full power, full mixture, and carburetor heat, but was still unable to maintain altitude. The pilot subsequently performed a forced landing to a private driveway. A postaccident examination of the wreckage revealed no evidence of preimpact mechanical anomalies that would have prevented normal engine operation. In addition, fuel was plumbed into the engine and the engine ran without anomaly. Although the weather conditions at the time of the accident were conducive to the accumulation of carburetor icing at glide power, the pilot reported that he used carburetor heat, which would have prevented the accumulation of ice.
