Analysis

The plt said he had just completed an aerial application operation and was returning to his base airfield to re-load. While in a low level cruise, the engine quit abruptly, and an emergency ldg was attempted in a soft, muddy soy bean field. During the ldg roll, the acft nosed over. Engine failure was attributed to a severed safety wire holding a bolt on the carburetor float valve, allowing the float to restrict the fuel flow.
