Background:     The FAA has received a report of a Cessna Model 182Q aeroplane with Air Plains Services Corporation STC SA00152WI installed that had an in-flight and post-landing fire.  The preliminary finding, per the United States National Transportation Safety Board (NTSB), is that the electrical cable between the forward ground power relay and the starter relay chafed on either the fuel strainer control or on the fuel line between the auxiliary electric fuel pump and the engine-driven fuel pump.  The cable shorted, welded the fuel strainer control cable to the firewall, and burned the fuel line between the auxiliary electric fuel pump and the engine-driven fuel pump.
                This Directive requires the disconnection or removal of the electrical cable between the forward ground power relay and the starter relay, the installation of a placard, the inspection of the fuel line between the auxiliary electric fuel pump and the engine-driven fuel pump for chafing and, if necessary, the replacement of the fuel line if chafing is found.  The Directive is issued to detect and correct interference between the ground power electrical cable, the fuel strainer cable and the fuel line between the auxiliary electric fuel pump and the engine-driven fuel pump.  This condition could lead to a fire in the engine compartment.
