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.
REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES
During the AIRBUS production flight test of an A330-300 aircraft, the Ram Air Turbine (RAT) did not
pressurize the green hydraulic system. Investigation revealed that the impeller drive (hex) shaft had a
reduced length of engagement with the pump drive shaft. This caused the impeller drive shaft to
disengage from the pump and disconnect the impeller. It was determined that the root cause of the
disconnection was the internal hex dimensions on the pump impeller shaft had been changed in a
supplier drawing in October 2007.
This Service Bulletin is published to advise all operators of A340-200/300 aircraft of the issue of
HAMILTON SUNDSTRAND Service Bulletin ERPS06M-29-19. This introduces an inspection to the RAT
hydraulic pump via serial numbers to ensure that all suspect RAT hydraulic pumps are captured. If the
RAT pump is suspected, It also outlines the modification to the RAT hydraulic pump by the installation
of a new hex drive shaft with an increased hex socket length and an increased internal hex depth.
This Service Bulletin installs a new impeller drive shaft that is match sized in the retrofit process of the
pump to ensure a minimum engagement of the hex drive shaft to eliminate the possibility of impeller
disengagement. The incorporation of this modification will provide improved reliability of the RAT.

During the AIRBUS production flight test of an A330-300 aircraft, the Ram Air Turbine
(RAT) did not pressurize the green hydraulic system. Investigation revealed that the
impeller drive (hex) shaft had a reduced length of engagement with the pump drive
shaft. This caused the impeller drive shaft to disengage from the pump and disconnect

SERVICE BULLETIN
(2) Objective/Action
This Service Bulletin is published to advise all operators of A340-200/300 aircraft of the
issue of HAMILTON SUNDSTRAND Service Bulletin ERPS06M-29-19. This introduces
an inspection to the RAT hydraulic pump via serial numbers to ensure that all suspect
RAT hydraulic pumps are captured. If the RAT pump is suspected, It also outlines the
modification to the RAT hydraulic pump by the installation of a new hex drive shaft with
an increased hex socket length and an increased internal hex depth.
(3) Advantages
This Service Bulletin installs a new impeller drive shaft that is match sized in the retrofit
process of the pump to ensure a minimum engagement of the hex drive shaft to
eliminate the possibility of impeller disengagement. The incorporation of this modification
will provide improved reliability of the RAT.
(4) Operational/Maintenance Consequences
None
D. DESCRIPTION
To accomplish this Service Bulletin it is necessary to :
Task 294093-831-848-001: Modification
(1) Re-identify the RAT Hydraulic Pump
(2) Replace the RAT Hydraulic pump
(3) Re-identify the RAT Module
E. COMPLIANCE
(1) Classification
MANDATORY: Service Bulletin must be accomplished.
(2) Accomplishment Timescale
This modification must be embodied within 36 months from the Airworthiness Directive
(AD) effective date. An AD will be issued to mandate the necessary changes.
This Service Bulletin has been classified Mandatory. It is expected that an Airworthiness
Directive (AD) published by the European Av iation Safety Agenc y (EASA) will be issued
to confirm this classification. It is anticipated that the AD will confirm the (thresholds
and/or intervals and/or date) given above but reference should be made to the AD for
confirmation of the mandated accomplishment timescale.
F. APPROVAL
The technical content of this document is approved under the authority of Design
Organisation Approval No. EASA.21J.031.
