Fracture of the piston rod for the Main Landing Gear (MLG) retraction-actuator has 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. The All Operator Telex (AOT) No. A330-32A3172 has been issued to request operators to carry out an ultrasonic inspection of the piston rod for the MLG retraction-actuator that have been in service for more than three years. The AOT is being followed up by the issue of Inspection Service Bulletin (ISB) A330-32-3173 which covers the Messier-Dowty Service Bulletin A33/34-32-222. Which additionally requests a detailed visual inspection. This Service Bulletin introduces a MLG retraction-actuator which has a solid piston rod. This new design is only intended for interim use to alleviate supply demands, it will not be installed on production aircraft. It is only intended to be installed to prevent an AOG situation. The solid piston rod is life limited to MPD Section 9-1. An improved design of hollow piston rod with a higher standard of corrosion protection will be introduced to replace the existing design through SB A330-32-3180. This Service Bulletin is superseded by SB A330-32-3180. Accomplishment of this Service Bulletin will prevent a possible AOG situation when a MLG retraction-actuator fails the inspection requirements of ISB A330-32-3173 and there are no other spare pre-modification MLG retraction-actuators available.
