REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

This Service Bulletin has been issued to inform operators of A318/

aircraft that there have been several reported in-service failure

Landing Gear (MLG) door actuator. The symptoms reported are slow 

the door opening/closing sequence, possibly leading to the genera

warnings of "L/G NOT DOWNLOCKED" and "L/G DOORS NOT CLOSED". Inves

subsequently found that the affected MLG door has been difficult 

manually (unusually high pressure was required to extend the actu

consequently open the door). The MLG door actuator was confirmed t

of the condition with a stiff action and often reduced stroke. Th

and associated retaining ring are typically found to be broken wi

damage to the damping housing from the resultant debris. The high 

delays the whole L/G extension/retraction sequence. The free-fall 

MLG could be impaired if friction is high enough.

This Service Bulletin gives instructions to check that when the M

released manually by using the door opening control-handle :

— it continuously opens by gravity once the handle is moved to the 

(close to the end of the travel it is normal that the door may 

manual load to fully open)

— the movement of the door is smooth and continuous with no exces

Accomplishment of this Service Bulletin will make sure that MLG d

that are found to have restricted movement during operational seq

replaced with a serviceable item.

The initial inspection must be accomplished before the MLG door a

C. REASON

(1) History

There have been several reported in-service failures 

door actuator. The symptoms reported are slow operati

opening/closing sequence, possibly leading to the ge

ECAM warnings of "L/G NOT DOWNLOCKED" and "L/G DOORS 

Investigations have subsequently found that the affe

has been difficult to open manually (unusually high 

required to extend the actuator and consequently ope

The MLG door actuator was confirmed to be the cause o

condition with a stiff action and often reduced strok

ring and associated retaining ring are typically foun

with subsequent damage to the damping housing from t

debris. The high friction delays the whole L/G extens

sequence. The free-fall mode of the MLG could be impa

friction is high enough.

D. DESCRIPTION

To accomplish this Service Bulletin it is necessary to :

(1) Config. 01

(a) Make sure that the work area is safe.

(b) Manually open the LH and RH MLG doors by using t

opening control-handle to check that :

— when the door is released it continuously ope

once the handle is moved to the open position 

end of the travel it is normal that the door m

manual load to fully open)

— the movement of the door is smooth and contin

excessive delay

(c) If the movement of the door is found to be rest
