### TITLE: HYDRAULIC POWER - GREEN AUXILIARY HYDRAULIC POWER (RAM AIR TURBINE) - RAT PUMP HEX SHAFT MODIFICATION **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR None MINOR 202538D50554 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 which had been changed in a supplier drawing in October 2007. The same tolerances that were introduced in the drawing for the A330/A340-200/-300 series had been used for the A340-500/-600 since the beginning of the A340-500/-600 program, therefore, all A340-500/-600 aircraft are affected. This Service Bulletin is published to advise all operators of A340-500/600 aircraft of the issue of HAMILTON SUNDSTRAND Service Bulletin ERPS33T-29-6. This introduces 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.

D. DESCRIPTION To accomplish this Service Bulletin it is necessary to : Task 295021-831-848-001: Modification (1) Remove the RAT (2) Modify the RAT module (Vendor) (3) Install a Modified RAT 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 Aviation Safety Agency (EASA) will be issued to confirm this classification. It is anticipated that the AD will confirm the interval 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. 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.
