Analysis narrative
While cruising at 7500 feet msl the pilot reported a gradual loss of engine power. The pilot established radio and radar contact with florence approach control and advised the controller of his engine problem. The pilot was given radar vectors to darlington county airport, the nearest suitable airport. Another pilot flying in the second airplane in the flight suggested several remedies for the loss of engine power. Finally, he suggested that the pilot check the magnetos. The pilot reported that the engine ran smoothly on one magneto but the engine almost quit when switched to the other magneto. Moments later the pilot reported a complete loss of engine power. The airplane disappeared off the radar scope and crashed 3 miles short of darlington county airport. The second airplane landed without incident but the pilot reported a layer of fog at the airport. The airplane was destroyed by impact forces and the post crash fire.
