Background:  Boeing has received reports of contamination of the fueling float switch by moisture or fuel, together with chafing of the float switch wiring against the fuel tank conduit.  This Directive, which requires an inspection to determine if float switches are installed and, if necessary, the installation of new float switches and protective sheathing in the electrical cable conduit; is issued to prevent the contamination and chafing, which could present an ignition source inside the fuel tank that could cause a fire or explosion.
