### TITLE: ELECTRICAL POWER -INSPECTION OF SHUT-OFF VALVE BONDING LEAD **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES During maintenance an operator has reported an inoperative GREEN hydraulic Fire Shut-Off Valve (FSOV). Troubleshooting evidenced some damages : - A wire located between Engine 2 hydraulic FSOV and wing rear spar (zones 575/675) has been found cut - A bonding lead (E0088-10-80) located between Rib 7A and Rib 8 below Hydraulic Pressure Lines has been found cut. Investigations on different aircraft have shown that some aircraft are fitted with bonding leads of (120mm (4.72in) length instead of 80mm (3.15in)). This overlength can lead to contact and chafing between the harness and the bonding lead, which can lead to the findings. It can also entail damages in case of lightning strike. This Inspection Service Bulletin requires inspection and repair (when necessary) of the : - Wires located between Engines hydraulic FSOV and wing rear spar (zones 575/675) - Two bonding leads (E0088-10-80) located between Rib 7A and Rib 8 below Hydraulic Pressure Lines. Accomplishment of this Inspection Service Bulletin will avoid such a case of inoperative hydraulic FSOV due to wiring damaged by a bonding lead and restore the aircraft system reliability.
