The NTSB's narrative final · quoted from the NTSB record

The private pilot reported that, shortly after the airplane departed the airport for the personal flight, the engine lost power. His attempt to restart the engine was unsuccessful. The pilot executed a forced landing to an open lot, and the airplane collided with terrain during the landing. Postaccident examination of the engine and airframe revealed no mechanical anomalies that would have precluded normal operation. Weather conditions about the time of the accident were conducive to the accumulation of carburetor icing at glide power. However, it could not be determined whether carburetor ice caused the loss of engine power because the engine was operating at takeoff power at the time.
