SUMMARY
This summary is for information only and is not approved for modification of the aircraft.
A. MODIFICATIONS
MODIFICATION CLASSIFICATION
MAJOR 210503C11181
MINOR None
NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the
mass, balance, structural strength, reliability, operational characteristics affecting
the airworthiness of the product. All other changes are major changes.
B. REASON
(1) History
Due to in service clamping pin rupture events, a design change of the High Pressure
Valve (HPV) has been implemented to improve HPV reliability and reduce clamping pin
rupture event.
(2) Objective/Action
This Service Bulletin is published to advise all operators of A330 aircraft of the
release of Ref. LIEBHERR AEROSPACE TOULOUSE SAS (F1958) VSB 71070-36-02 which
modifies the HPV.
It consists in the following HPV butterfly sub-assembly changes:
- Increase clamping pin diameter and quantity. Pre-MOD 1.20 mm (0.047 in.)
section clamping pin (one unit) is replaced by post-MOD 1.50 mm (0.059 in.)
section clamping pins (two units) providing higher resistance and better load
distribution. In the post-MOD design, two clamping pin legs need to be broken to
release the seal and generate Foreign Object Damage (FOD).
- Holes change to enable retainer clamping pin proper installation in the butterfly
sub-assembly:
- Butterfly holes diameter of 1.250 mm (0.0492 in.) in pre-MOD (two holes)
is increased up to 1.550 mm (0.0610 in.) diameter in post-MOD (two holes)
- Sealing ring holes diameter of 1.700 mm (0.0669 in.) in pre-MOD (two
holes) is increased up to 2.0 mm (0.0787 in.) in post-MOD (two holes)
- T wo new holes are created for the butterfly and the sealing ring with the
new diameter.
- Change butterfly sealing ring expander shape. The expander function is to push
the butterfly sealing ring out to ensure the contact with the valve body when the
butterfly is closed. The location of the expander is the same in the pre-MOD and
the post-MOD. However, the post-MOD expander is changed with a smoother
shape (from V shape in the pre-MOD to S shape in the post-MOD) to reduce the
compression loads.
Note that this modification has no impact on the installation (mechanical and
electrical interfaces have not been modified) nor the HPV performances.

(3) Advantages
The HPV design change aims to reduce the number of HPV butterfly clamping pin
breakage, trying to avoid the subsequent sealing ring losses and the FOD generation
downstream the HPV.
The accomplishment of this Service Bulletin cancels the mandatory regular change
of HPV clamping pin as per Ref. A36L009-22-03. In addition, this Service Bulletin, in
combination with BMC software (SW) 5.0 upgrade, is the terminating action to the AOT
mandated by EASA Airworthiness Directive (AD) 2023-0111 R1.

D. DESCRIPTION
NOTE: T o accomplish this Service Bulletin, you have two options.
T o accomplish this Service Bulletin it is necessary to:

2 Replace the HPV (FIN 4000HA2) on Engine 2
E. COMPLIANCE
(1) Classification
RECOMMENDED: Service Bulletin recommended to be accomplished to prevent
significant operational disruptions.
(2) Accomplishment Timescale
Accomplishment of this Service Bulletin is recommended at the earliest opportunity
where manpower and facilities are available.
It is not required to retrofit both affected HPV at the same time. The retrofit of the
HPV should be done by attrition and can be done during different maintenance stops
according to the operator’s maintenance schedule. It is allowed to have a mixed
configuration of pre-MOD and post-MOD HPV. In this case, it is the responsibility of the
operator to ensure the traceability of the aircraft/equipment configuration.
F. APPROVAL
The technical content of this document is approved under the authority of the Design
Organisation Approval ref. EASA.21J.031.
If an aircraft listed in the applicability 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.
