Event Summary
While cruising at 7500 feet MSL, a pilot reported a gradual loss of engine power. The pilot established radio and radar contact with Florence Approach Control and advised the controller of the engine problem. The controller provided radar vectors to Darlington County Airport, identified as the nearest suitable airport.
Engine Troubleshooting
Another pilot flying in a second airplane within the same flight suggested several remedies for the loss of engine power. Eventually, he recommended checking the magnetos. The pilot reported that the engine ran smoothly on one magneto but nearly quit when switched to the other magneto. Moments later, the pilot reported a complete loss of engine power.
Final Descent and Crash
The airplane disappeared off the radar scope and crashed 3 miles short of Darlington County Airport. The second airplane landed without incident. That pilot reported a layer of fog at the airport. The airplane was destroyed by impact forces and a post-crash fire.
