Analysis
The student pilot stated that at 3000 ft, 14 NM north of the Danville VOR, the engine began vibrating. The engine lost power and the pilot was forced to land in a bean field approximately 4 miles north of the Danville airport. Engine examination revealed the adjustment screw in the rocker arm for the number 4 intake valve worked loose preventing the valve from operating.
