Incident Overview
During a cruise flight, the pilot encountered a drop in engine power. He applied carburetor heat and power was regained. A precautionary landing was made at Accomack County Airport. Several engine runups were performed on the ground, and no problem was detected. The pilot then departed the airport.
Second Power Loss Event
Approximately 10 minutes after departure, while at 3,500 feet mean sea level (MSL), a power loss of 1,000 RPM occurred. The pilot attempted to apply carburetor heat, but the control knob was stuck and he was unable to turn it on. At the reduced power setting, the aircraft descended to 2,000 feet MSL, where a total loss of engine power occurred.
Forced Landing
The pilot executed a forced landing onto an open field. Upon touchdown, the aircraft nosed over in the soft ground.
