Put this Revision Transmittal Sheet in front of the Service Bulletin. HISTORY OF PREVIOUS REVISIONS Revision 01 of this Service Bulletin was issued to add a new AD (CN) No. F-2004-086 (B) to supersede AD (CN) No. F-2003-458 (B) and mandates this Service Bulletin. This was due to the addition of the repetitive 7 day inspection of the complete chromed area of the piston rod. Also the opportunity was taken to update the aircraft effectivity and clarify the aircraft configurations. Revision 02 of this Service Bulletin was issued to show the changes in the inspection procedures and to include the drainage of water or other fluids from the piston rod. The mandatory accomplishment timescales were also added. Revision 03 was issued to inform operators that: — A one-time ultrasonic longitudinal and circumferential inspection on the full piston rod was added. — Modification Service Bulletin references were added as a closing action. — Accomplishment timescale was amended. — The interval for the fluid drainage was amended. — Effectivity was revised. — Config. 01 was added.

ATA SYSTEM : 32 TITLE : LANDING GEAR - MLG - INSPECTION OF THE MLG RETRACTION ACTUATOR PISTON-ROD MODIFICATION No. : None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES A rupture of a Main Landing Gear (MLG) retraction actuator piston rod-end has occurred on an in-service A330 aircraft. This resulted from internal corrosion and circumferential cracking around the painted upper end of the piston rod. A longitudinal crack has also been found on the chromed part of a retraction actuator piston-rod. Investigations indicate that the crack started from a line of corrosion pitting within the piston rod bore. All Operator Telex. (AOT) No. A330-32A3172 was issued to request operators to carry out an ultrasonic inspection of the retraction actuator piston rods that have been in service for more than six years. The Messier Dowty Service Bulletin A33/34-32-222 requires the actions that follow on the MLG retraction actuator piston rods that have been in service for three years or more:- — A visual inspection of the chromed area of the piston rods for cracks. — The draining of water or other fluids from the piston rods which could freeze and cause future cracks. — A repeat ultrasonic longitudinal inspection of the painted upper end of the piston rods for corrosion pitting and/or circumferential cracks. — A one-time ultrasonic longitudinal and circumferential inspection of the full length of the piston rods for corrosion pitting and/or circumferential cracks. This Service Bulletin supersedes AOT A330-32A3172. The accomplishment of this Service Bulletin makes sure that the MLG retraction actuator rod has no cracks and is free of any severe internal corrosion pitting that could cause cracks.

SERVICE BULLETIN SUMMARY

DATE : Dec 17/03 SERVICE BULLETIN No. : A330—32—3173 REVISION No. : 04 — Jun 12/06 Page : Printed in FRANCE © AIRBUS, 2006 All rights reserved Original issue of this Service Bulletin was rendered Mandatory by Airworthiness Directive (AD) (Consigne de Navigabilite (CN)) No. F-2003-458 (B). A second in-service piston rod rupture occurred as a result of a line of corrosion pitting within the piston-rod bore along the chromed length. This occurrence led to a revision of the requirement for the inspection of the piston-rods chromed area. Following this second event a new AD (CN) F-2004-086 (B) was issued to supersede AD (CN) No. F-2003-458(B) and to mandate this Service Bulletin at revision 01 and above. A third in-service retraction actuator piston rupture has occurred. As with the first rupture, this failure resulted from internal corrosion and circumferential cracking around the painted upper end of the piston rod. Subsequently, another piston rod has been found in operation with a longitudinal crack in the chromium plated part of the piston rod. Investigations indicate that the crack started from a line of corrosion pitting within the piston rod bore. The accomplishment of Service Bulletin A330-32-3174 Rev 02 or Service Bulletin A330-32-3180 Rev 01 cancels the requirements of this Service Bulletin. NOTE : The accomplishment of Service Bulletin A330-32-3174 Rev 02 is the interim solution for the piston rod actuator. Service Bulletin A330-32-3180 Rev 01 will take the piston rod actuator to Design Service Goal.

(3) Advantages The accomplishment of this Service Bulletin makes sure that the MLG retraction actuator rod has no cracks and is free of any severe internal corrosion pitting that could cause cracks. This Service Bulletin supersedes AOT A330-32A3172. (4) Operational/Maintenance Consequences None D. DESCRIPTION To accomplish this Service Bulletin it is necessary to: (1) Config. 01 (a) Get access to the MLG (LH and RH) retraction actuator. NOTE : It is not necessary to raise the aircraft on jacks for this inspection. (b) Do a DVI of the chromed part of the retraction actuator piston rod for cracks in accordance with the Messier-Dowty Service Bulletin No. A33/34-32-222. 1 If one or more cracks are found during the DVI, replace the actuator BEFORE THE NEXT FLIGHT. 2 If no cracks are found, do a repeat DVI at the specified intervals given in para 1.E.(2)(b). 3 In the event of findings during the DVI, the piston rod vent hole should be sealed to retain the contents of the internal volume, before the removal and the return of the retraction actuator in accordance with the Messier-Dowty Service Bulletin No. A33/34-32-222. 4 Report all retraction actuators rejected during the DVI in accordance with the instructions in Messier-Dowty Service Bulletin No. A33/34-32-222. (c) Drain the fluid from the retraction actuator piston rod and seal the vent hole in accordance with the Messier-Dowty Service Bulletin No. A33/34-32-222.
