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 bore. All Operator Telex No.A330-32A3172 was issued for an inspection of the retraction actuator piston rod that has been in service for more than six years. This Service Bulletin has been issued to advise operators of the issue of the Messier-Dowty Service Bulletin A33/34-32-222. The Messier-Dowty Service Bulletin is for a visual inspection of the chromed area of the piston rods for cracks and ultrasonic inspection of the inner surface of the piston rods for corrosion pitting and cracks of piston rods that have been in service for three years or more. The accomplishment of the Service Bulletin makes sure that the MLG retraction actuator rods have no cracks and are free of any internal corrosion pitting that could cause cracks. It is recommended to accomplish this Service Bulletin within four months from the date of receipt of the Service Bulletin or 250FC or 1400 FH, or from the date of the last inspection that was done in accordance with AOT A330-32A3172, whichever occurs first. Repeat inspections are to be done at every 1400FH or 250FC or four months, whichever occurs first. It is anticipated that this Service Bulletin will be made mandatory.

REASON (1) History (a) A rupture of a MLG retraction actuator piston rod-end has occurred on a in-service A330 aircraft. 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. (b) All Operator Telex 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. (2) Objective/Action This Service Bulletin has been issued to advise operators of the issue of the Messier-Dowty Service Bulletin A33/34-32-222. The Messier-Dowty Service Bulletin is for the visual inspection of the chromed area of the piston rods for cracks and ultrasonic inspection of the inner surface of the piston rods for corrosion pitting and/or cracks of piston rods that have been in service for three years or more. (3) Advantages (a) The accomplishment of this Service Bulletin makes sure that the MLG retraction actuator rod has no cracks and is free of any internal corrosion pitting that could cause cracks. (4) Operational/Maintenance Consequences None D. DESCRIPTION To accomplish this Service Bulletin it is necessary to: (1) Get access to the MLG (LH and RH) retraction actuator. NOTE : It is not necessary to raise the aircraft on jacks for this inspection. (2) Do a visual inspection of the chromed area of the actuator piston rod for cracks in accordance with the Messier-Dowty Service Bulletin A33/34-32-222.

(4) If cracks or corrosion pitting are found replace the retraction actuator. (5) If cracks or corrosion pitting are not found, do a repeat inspection at the specified intervals given in this Service Bulletin. (6) Report all findings (including no findings) to AIRBUS. E. COMPLIANCE (1) Classification Recommended (2) Accomplishment Timescale NOTE : The threshold of three years is from the date of the MLG retraction actuator piston rods first entry into service. If spare piston rods of the same part number have been installed then the threshold is three years from the date of first installation of the piston rods on any aircraft. (a) It is recommended to accomplish this Service Bulletin within four months from the date of receipt of the Service Bulletin or 250 FC or 1400 FH, or from the date of the last inspection that was done in accordance with AOT A330-32A3172, whichever occurs first. (b) Repeat inspections are to be done at every 1400FH or 250FC or four months, whichever occurs first. (c) It is anticipated that the accomplishment of this Service Bulletin will be made mandatory. F. APPROVAL The technical content of this Service Bulletin has been approved under the authority of the DGAC Design Organisation Approval No. F.JA.02. 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.
