### TITLE: ELECTRICAL POWER-INSPECTION OF SHUT-OFF VALVE BONDING LEAD MODIFICATION No.: None This page transmits Revision No.01 of Service Bulletin No.A300-24-0106 ADDITIONAL WORK **CONF ALL ADDITIONAL WORK is required by this revision for aircraft inspected by the original issue of this Service Bulletin. The ADDITIONAL WORK for this Service Bulletin is issued to ensure that the correct bonding leads (one on RH and one on LH) are inspected. At original issue, the description of the bonding leads (two on RH and two on LH) to be inspected was misleading and some operators could have inspected other bonding leads than the one to be checked. REASON Revision 01 issued to clarify the bonding leads (RH and LH) to be inspected, to replace PN E0088-10-80 by PN E0088-10-80NN (as per Standards Manual evolution) and to update the effectivity. CHANGES The main changes of revision 01 are: - To modify figure A-FBAAA to correct the bonding lead to be inspected. - To modify the Inspection Report (figure A-FRAAA) in accordance with the correct bonding leads (RH and LH) to be inspected. - To modify the COMPA01: . Bonding lead PN E0088-10-80 replaced by PN E0088-10-80NN in accordance with Standards Manual. . Bonding leads quantity changed from 4 to 2. . Nuts (PN NSA5050-3) quantity changed from 8 to 4.

### 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 (E0088-10-80NN) 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 (RH and LH) (E0088-10-80NN) 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.
