Unsafe Condition
A hot spot may develop in the main fuel tank under certain failure conditions of the solenoid of the level control pilot valve, the reed switch of the main tank overflow valve, the level float switch of the collector tank, or the solenoid of the main tank fueling shut-off valve. This could create an ignition source in the main tank vapor space, possibly resulting in a fuel tank explosion and consequent loss of the airplane.
