Analysis

According to the acting airport manager at Pickens County Airport, N8048G, refueled with about 20 gallons of 100 octane low lead fuel. After several start attempts the airplane taxied from the fuel pits a short distance before the engine quit again. The pilot, requested a pair of pliers and removed the fuel filter and found it to be 90 percent clogged. After cleaning the fuel filter and replacing it, he told the acting airport manager that he was going to return to Dalton Municipal. According to the pilot, during cruise flight the engine quit. The pilot executed a forced landing into a rough field, and hit hard collapsing the landing gear, buckling the firewall and engine mounts. Examination of the airplane found sealing compound in the upper fuel tank. The sealing compound was also found in the fuel line and fuel filter. The pilot stated that he should have investigated and cleaned the fuel system prior to taking off.
