Incident Details
The pilot reported that the flight's purpose was to drop parachute jumpers. After the jumpers deplaned at an altitude of 8,500 feet above mean sea level (MSL), the pilot reduced power to initiate a descent and landing at the departure airport. The pilot stated that he did not apply carburetor heat during the entire descent and entered the traffic pattern with reduced power.
Engine Malfunction
On final approach, the pilot applied throttle, but the engine did not respond. Instead, the engine ran roughly. The pilot noted that the aircraft was descending rapidly and that it became clear he would not be able to land on the airport runway.
Forced Landing
The pilot subsequently landed the aircraft in a plowed, muddy field. During the landing, the aircraft nosed over. The pilot successfully exited the aircraft.
