REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

The Fuel Vent Protector PN 786073-1-0 FIN 194QM (195QM) is part of the stack pipe connected to the

National Advisory Committee for Aeronautics (NACA) Vent Intake Assembly. If a ground fire occurs, it

prevents the ignition of the fuel vapour in the surge tank (and therefore, the venting system). It also

allows air to flow freely through it in two directions and prevents ice formation. The Fuel Vent Protector

consists of an ice protector cartridge and a flame arrestor cartridge within a metal body. A circlip holds

the ice protector and flame arrestor cartridges in position.

More than one circlip out of a batch of 400 produced by the vendor Intertechnique in August 2012, were

found corroded. Several circlips have been found to be corroded due to a surface treatment (shot

peening) operation being omitted during manufacture. Two suspect circlips have been inspected and

the presence of corrosion has been confirmed.

Fuel Vent Protector FIN 48QM (49QM) are not affected by this Service Bulletin.

This Inspection Service Bulletin introduces a one-time Detailed Inspection of the Fuel Vent Protector. If

the Part Number (PN) and Serial Number (SN) of the Fuel Vent Protector are found to be part of the

affected batch, the Fuel Vent Protector (containing the circlip) must be replaced.

This one-time inspection will detect affected units and prevent possible future in-service issues.

(1) History

The Fuel Vent Protector PN 786073-1-0 FIN 194QM (195QM) is part of the stack pipe

connected to the National Advisory Committee for Aeronautics (NACA) Vent Intake

Assembly. If a ground fire occurs, it prevents the ignition of the fuel vapour in the surge

tank (and therefore, the venting system). It also allows air to flow freely through it in

two directions and prevents ice formation. The Fuel Vent Protector consists of an ice

protector cartridge and a flame arrestor cartridge within a metal body. A circlip holds the

ice protector and flame arrestor cartridges in position.

More than one circlip out of a batch of 400 produced by the vendor Intertechnique in

August 2012, were found corroded. Several circlips have been found to be corroded due

to a surface treatment (shot peening) operation being omitted during manufacture. Two

suspect circlips have been inspected and the presence of corrosion has been confirmed.

Fuel Vent Protector FIN 48QM (49QM) are not affected by this Service Bulletin.

F. APPROVAL

The technical content of this document is approved under the authority of 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.

G. MANPOWER

The manpower estimates given in this Service Bulletin are based on the direct labor cost to

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.
