right wing vent boxes with new electrical bonding attaching hardware, together with accomplishing resistance testing of the new electrical bonds, and fuel leakage testing of the reworked nipple assemblies.  The Directive results from fuel system reviews conducted by the manufacturer.
             The Directive is issued to ensure a conductive path is provided, from the bulkhead nipple assemblies of the left and right wing vent boxes to the airframe structure inside the wing fuel tanks, to dissipate high-amperage lightning-induced currents, which might otherwise create an ignition source for fuel vapours inside the wing vent boxes and lead to an explosion of the fuel tanks.
