The Piper Sargota was on an "Angel Flight" mission from Florida.
Angel Flight is for people who need to fly for medical treatment to a distant city yet cannot afford the trip.
According to the Johnston County sheriff, the plane's engine went out. That forced the pilot to land in a soybean field near Selma. Neither the pilot nor the two passengers were injured.
They were taken to the airport, where they caught a flight to their final destination of New Jersey.
