Accident Narrative
The pilot reported that prior to takeoff for a planned 10-minute flight, both fuel tanks contained over 5 gallons of fuel and all airplane systems were functioning normally. Upon arrival at the destination airport, the pilot entered the traffic pattern. Carburetor heat was applied, the throttle was retarded, and the airplane descended. After turning onto the base leg, the pilot moved the throttle forward to increase engine power. The engine then "blubbered and totally lost power." Unable to glide to the runway, the pilot made a forced landing in a soft field adjacent to the airport. During the landing, the airplane nosed over.
Examination
An FAA coordinator responded to the accident site and examined the wreckage. The FAA reported that it examined the powerplant, induction system, engine controls, and magnetos. The ignition switch and the carburetor were also functionally examined. No evidence was found of any mechanical malfunctions. The reason for the interruption of engine power was not determined.
