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.

C. REASON

(1) History

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.

(2) Objective/Action

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.

(3) Advantages

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.

(4) Operational/Maintenance Consequences

None

D. DESCRIPTION

To accomplish this Service Bulletin it is necessary to :

Accomplishment of this Service Bulletin is expected to be rendered mandatory by the

issue of an Airworthiness Directive (AD) published by the European Aviation Safety

Agency (EASA). It is anticipated that the AD will confirm the 4500 FH or 30 months

given above but reference should be made to the AD for confirmation of the mandated

accomplishment timescale.

F. APPROVAL

Approved under EASA Design Organisation Approval No. EASA 21J.031.

If an aircraft listed in the effectivity has a modification or repair embodied that is not of

AIRBUS origin, and which affects the content of this Service Bulletin, the operator is

responsible for obtaining approval by its airworthiness authority for any adaptation necessary

before incorporation of the Service Bulletin.

do the work. These estimates assume that the work will be done by experienced personnel,

and may need to be revised upwards to suit operator’s circumstances. The estimates do not

include the time to prepare, plan or inspect the work. Manufacture and procurement of parts

and tools, drying times for paints, sealants, etc., and general administration work are also not

included.
