ATA SYSTEM : 32 TITLE : LANDING GEAR - MLG - INSPECTION OF MLG RETRACTION ACTUATOR PISTON ROD MODIFICATION No. : None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES A rupture of a 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. A340-32A4211 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. This Service Bulletin has been issued to advise operators of the issue of the Messier-Dowty Service Bulletin No. A33/34-32-222. This Messier-Dowty Service Bulletin has been revised to modify the inspection procedures which now require 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 and the 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. This Service Bulletin supersedes AOT A340-32A4211. 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. 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. This occurrence led to a revision of the requirement for the inspection of the piston-rods chromed area.

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.
