Read the full NTSB narrative
Shortly after takeoff from a remote airstrip, the pilot noted a loss of engine power, and smoke in the cockpit. While attempting to return to the airstrip, the engine lost all power, and the pilot was forced to land on a snow-covered field. During landing, the main wheels broke through the crusted snow, and the airplane nosed over. A postaccident inspection disclosed that the exhaust stack had separated from the cabin heater's heat exchanger. The hot exhaust gasses burned associated ducts, wires, and the lower engine cowling.
