Read the full NTSB narrative

THE ACFT WAS ENGAGED IN AN AERIAL APPLICATION FLT WHEN THE ENG LOST POWER. THE PLT MADE A FORCED LANDING IN A BEAN FIELD. DURING THE LANDING ROLL, THE ACFT STRUCK A LEVEE THAT WAS OBSCURED BY HIGH VEGETATION & NOSED OVER. A POST-ACCIDENT INVESTIGATION REVEALED THE CARBURETOR NEEDLE VALVE SEAT WAS LOOSE & ALLOWED FUEL TO BYPASS THE VALVE & ENTER THE INTAKE MANIFOLD. AN INTERVIEW WITH PERSONNEL THAT OVERHAULED THE CARBURETOR REVEALED THAT RECOMMENDED TORQUE VALVES WERE NOT BEING USED DURING INSTALLATION OF THE NEEDLE VALVE SEAT. AN INVESTIGATION ALSO REVEALED THAT PRIOR TO THIS FLT, THE ENG COULD NOT BE SHUT DOWN BY MOVING THE MIXTURE CONTROL TO THE 'CUT-OFF' POSITION. TO STOP THE ENG ON PREVIOUS FLTS, THE PLT USED THE FUEL SELECTOR VALVE BY MOVING IT TO THE 'OFF' POSITION.
