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.A340-32A4211 was issued for an ultrasonic 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 part of the piston rods 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. The accomplishment of this Service Bulletin makes sure that the MLG retraction actuator rods have no cracks and are free of any internal 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 250 FC or 1400 FH, or from the date of the last inspection that was done in accordance with AOT A340-32A4211, whichever occurs first. Repeat inspections are to be done at every 1400FH or 250FC or four months, whichever occurs first. It is anticipated that the accomplishment of this Service Bulletin will be made mandatory.
