### TITLE: HYDRAULIC POWER - GREEN AUXILIARY HYDRAULIC POWER (RAM AIR TURBINE) - INTRODUCE NEW SHIMMING PROCEDURE OF RAT DEPLOY SOLENOIDS **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR 204067D50787 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. REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES An A330 operator experienced that a Ram Air Turbine (RAT) did not deploy when tested. An investigation, conducted by HAMILTON SUNDSTRAND and ARKWIN INDUSTRIES, has found that the RAT did not deploy because there was not sufficient stroke inside one of the actuator deploy solenoids due to insufficient shimming. The actuators will be modified by HAMILTON SUNDSTRAND to make sure they are correctly shimmed with the correct stroke length. This Service Bulletin is published to advise all operators of A340 aircraft of the issue of HAMILTON SUNDSTRAND Service Bulletin No. ERPS06M-29-21. HAMILTON SUNDSTRAND Service Bulletin No. ERPS06M-29-21 describes the procedure to identify the part number of the RAT actuator and modify the shimming procedure of the RAT actuator. The accomplishment of this Service Bulletin will contribute to ensure the correct function of the RAT.

Task 294097-831-848-001: MODIFICATION (1) Identify the Part and Serial Number of the RAT Actuator (2) Modify the RAT Actuator E. COMPLIANCE (1) Classification MANDATORY: Service Bulletin must be accomplished. (2) Accomplishment Timescale 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 threshold of 36 months given 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.
