HISTORY OF PREVIOUS REVISIONS

Revision 01 of this Service Bulletin was issued to add a new A

F-2004-086 (B) to supersede AD (CN) No. F-2003-458 (B) and ma

Service Bulletin. This was due to the addition of the repetit

inspection of the complete chromed area of the piston rod. Al

opportunity was taken to update the aircraft effectivity and 

aircraft configurations.

Revision 02 of this Service Bulletin was issued to show the c

inspection procedures and to include the drainage of water or 

from the piston rod. The mandatory accomplishment timescales w

added.

Revision 03 was issued to inform operators that:

— A one-time ultrasonic longitudinal and circumferential insp

full piston rod was added.

— Modification Service Bulletin references were added as a clo

— Accomplishment timescale was amended.

— The interval for the fluid drainage was amended.

— Effectivity was revised.

— Config. 01 was added.

REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

A rupture of a Main Landing Gear (MLG) retraction actuator piston

As with the first rupture, this failure resulted from 

corrosion and circumferential cracking around the pai

of the piston rod.

Subsequently, another piston rod has been found in op

Investigations indicate that the crack started from 

corrosion pitting within the piston rod bore.

this inspection.

(b) Do a DVI of the chromed part of the retraction a

rod for cracks in accordance with the Messier-Do

Bulletin No. A33/34-32-222.

1 If one or more cracks are found during the DV

actuator BEFORE THE NEXT FLIGHT.

2 If no cracks are found, do a repeat DVI at t

intervals given in para 1.E.(2)(b).

3 In the event of findings during the DVI, the 

vent hole should be sealed to retain the cont

internal volume, before the removal and the 

retraction actuator in accordance with the Me

Service Bulletin No. A33/34-32-222.

4 Report all retraction actuators rejected dur

accordance with the instructions in Messier-D

Bulletin No. A33/34-32-222.

(c) Drain the fluid from the retraction actuator pi

seal the vent hole in accordance with the Messie

Service Bulletin No. A33/34-32-222.
