### TITLE: LANDING GEAR - MAIN GEAR - INTRODUCE NEW RE-DESIGNED PISTON ROD ON THE RETRACTION ACTUATOR **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR 52980H15418 MINOR 54648H15734 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 Two fractures of the piston rod for the MLG retraction-actuator have occurred on an in-service A330 aircraft, close to the spherical bearing. Additionally another piston rod has fractured, due to a longitudinal crack. Both failures are corrosion related. In addition, two fatigue test failures occurred on an A340-600 piston rod, one occurred at the lug net tension area originating from the chrome plating run-out. The other failure was caused by the absence of shot peening resulting in machining marks remaining in the bore. The mandatory ISB No. A330-32-3173 was issued to do an ultrasonic NDT and detailed visual inspection of the MLG retraction-actuator piston rod. Service Bulletin No. A330-32-3174 (Mod No. 52424H15395) was also issued to introduce a MLG retraction-actuator which had a solid piston rod. This new design was only intended for interim use to alleviate supply demands. It was only intended to be installed to prevent an AOG situation. This Service Bulletin is published to advise all operators of A330 aircraft of the issue of Messier-Dowty Service Bulletin No. A33/34-32-227. This Service Bulletin introduces a new MLG retraction-actuator which has a re-designed piston rod. The new re-designed piston rod has the following changes:

# @A330 SERVICE BULLETIN SUMMARY - an increased radial wall thickness - revised internal bore configuration - safety vent hole removed - new rod screwed plug which now includes a safety vent hole. NOTE: Retraction actuators P/N 114256004-005 (post production modification) and P/N 114256004-000 (post retrofit modification) are fully two-way interchangeable with each other (as they are effectively the same LRU identified differently). Accomplishment of this Service Bulletin cancels the mandatory inspection requirements of Inspection Service Bulletin No. A330-32-3173. Accomplishment of this Service Bulletin introduces a new piston rod. The new piston rod has a higher fatigue life limit than the part number presently defined in the Airworthiness Limitation Section (ALS) Part 1.

# @A330 SERVICE BULLETIN (6) Material Effectivity **CONF 001 thru 002 MATERIAL QTY PER A/C SEE NOTES Reidentified part set REIDB01 1 **CONF 003 MATERIAL QTY PER A/C SEE NOTES Reidentified part set REIDB02 1 **CONF ALL B. CONCURRENT REQUIREMENTS None C. REASON (1) HistoryTwo fractures of the piston rod for the MLG retraction-actuator have occurred on an inservice A330 aircraft, close to the spherical bearing. Additionally another piston rod has fractured, due to a longitudinal crack. Both failures are corrosion related. In addition, two fatigue test failures occurred on an A340-600 piston rod, one occurred at the lug net tension area originating from the chrome plating run-out. The other failure was caused by the absence of shot peening resulting in machining marks remaining in the bore. The mandatory ISB No. A330-32-3173 was issued to do an ultrasonic NDT and detailed visual inspection of the MLG retraction-actuator piston rod. Service Bulletin No. A330-32-3174 (Mod No. 52424H15395) was also issued to introduce a MLG retraction-actuator which had a solid piston rod. This new design was only intended for interim use to alleviate supply demands. It was only intended to be installed to prevent an AOG situation. (2) Objective/Action This Service Bulletin is published to advise all operators of A330 aircraft of the issue of Messier-Dowty Service Bulletin No. A33/34-32-227. This Service Bulletin introduces a new MLG retraction-actuator which has a re-designed piston rod. The new re-designed piston rod has the following changes: - an increased radial wall thickness - revised internal bore configuration - safety vent hole removed

# @A330 SERVICE BULLETIN - new rod screwed plug which now includes a safety vent hole. NOTE: Retraction actuators P/N 114256004-005 (post production modification) and P/N 114256004-000 (post retrofit modification) are fully two-way interchangeable with each other (as they are effectively the same LRU identified differently). (3) Advantages Accomplishment of this Service Bulletin cancels the mandatory inspection requirements of Inspection Service Bulletin No. A330-32-3173. (4) Operational/Maintenance Consequences Accomplishment of this Service Bulletin introduces a new piston rod. The new piston rod has a higher fatigue life limit than the part number presently defined in the Airworthiness Limitation Section (ALS) Part 1. D.

COMPLIANCE (1) Classification MANDATORY: Service Bulletin must be accomplished. (2) Accomplishment Timescale Accomplishment of this Service Bulletin has been rendered mandatory by the issue of an Airworthiness Directive (AD) published by the European Aviation Safety Agency (EASA). The AD must be used as the reference document for the mandatory accomplishment timescale. F. APPROVAL The technical content of this document is approved under the authority of Design Organization 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. **CONF 001 Task 323180-831-895-001: MODIFICATION Get Access 0.50 On Aircraft Remove the Applicable MLG Retraction Actuator 5222GA and 5223GA 10.00 Install the Modified MLG Retraction Actuator 10.00 Tests 1.50 Close-Up 0.50 TOTAL MANHOURS 22.50 ELAPSED TIME (HOURS) 22.50 DATE: Sep 20/04 SERVICE BULLETIN No.: A330-32-3180 REVISION No.: 05 - Jan 27/14 Page: 7 7

3. ACCOMPLISHMENT INSTRUCTIONS Task 323180-831-895-001 - MODIFICATION WARNING: MAKE SURE THAT YOU OBEY ALL THE WARNINGS AND ALL THE CAUTIONS INCLUDED IN THE REFERENCED PROCEDURES. WARNING: MAKE SURE THAT THE SAFETY DEVICES AND WARNING NOTICES IN POSITION BEFORE YOU START A TASK ON OR NEAR: - THE FLIGHT CONTROLS - THE FLIGHT CONTROL SURFACES - LANDING GEAR AND RELATED DOORS - COMPONENTS THAT MOVE. MOVEMENT OF COMPONENTS CAN KILL OR INJURE PERSONS. CAUTION: ALWAYS OBEY THE PRECAUTIONS THAT FOLLOW TO KEEP ELECTRICAL WIRING IN A SATISFACTORY CONDITION (ELECTRICALLY AND MECHANICALLY SERVICEABLE). WHEN YOU DO MAINTENANCE WORK, REPAIRS OR MODIFICATIONS, ALWAYS KEEP ELECTRICAL WIRING, COMPONENTS AND THE WORK AREA AS CLEAN AS POSSIBLE. TO DO THIS: - PUT PROTECTION, SUCH AS PLASTIC SHEETING, CLOTHS, ETC. AS NECESSARY ON WIRING AND COMPONENTS - REGULARLY REMOVE ALL SHAVINGS, UNWANTED MATERIAL AND OTHER CONTAMINATION. THESE PRECAUTIONS WILL DECREASE THE RISK OF CONTAMINATION AND DAMAGE TO THE ELECTRICAL WIRING INSTALLATION. IF THERE IS CONTAMINATION, REFER TO ESPM 20-55-00. NOTE: The accomplishment instructions of this Service Bulletin refer to procedures included in other AIRBUS documents. When the words ’refer to’ are used and the operator has an accepted alternative procedure, the accepted alternative procedure can be used. When the words ’in accordance with’ are included in the instruction, the procedure in the AIRBUS document must be used. NOTE: The access and close-up instructions, not comprising return to service tests, in this Service Bulletin do not constitute or affect the technical intent of the Service Bulletin. Operators can therefore, as deemed necessary, omit or add access and/or close-up steps to add flexibility to their maintenance operations as long as the technical intent of the Service Bulletin is met within the set parameters.
