PISTON-ROD

MODIFICATION No. : None

REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

A rupture of a MLG retraction actuator piston rod-end has occurre

in-service A330 aircraft.

A longitudinal crack has also been found on the chromed part of a 

actuator piston rod. Investigations indicate that the crack start

of corrosion pitting within the piston bore.

All Operator Telex No.A330-32A3172 was issued for an inspection o

retraction actuator piston rod that has been in service for more 

This Service Bulletin has been issued to advise operators of the 

Messier-Dowty Service Bulletin A33/34-32-222. The Messier-Dowty Se

is for a visual inspection of the chromed area of the piston rods 

ultrasonic inspection of the inner surface of the piston rods for 

pitting and cracks of piston rods that have been in service for t

more.

The accomplishment of the Service Bulletin makes sure that the MLG 

actuator rods have no cracks and are free of any internal corrosio

could cause cracks.

It is recommended to accomplish this Service Bulletin within four 

the date of receipt of the Service Bulletin or 250FC or 1400 FH, 

date of the last inspection that was done in accordance with AOT A

whichever occurs first. Repeat inspections are to be done at ever

250FC or four months, whichever occurs first.

It is anticipated that this Service Bulletin will be made mandato
