REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

On the Nose Landing Gear (NLG) of several A340-500/600 aircraft, corrosion has been found in the

upper and/or lower lugs of the drag stay lower-arms (discovered during maintenance checks or aircraft

walk arounds). No parts have failed in service as a result of corrosion.

An engineering review has established that a significant level of corrosion may lead to a potential failure

of the drag stay lower-arm. Therefore action is necessary to make sure the continued airworthiness of

the fleet.

This Service Bulletin is published to advise all operators of A340-500/600 aircraft of the issue of

MESSIER DOWTY Service Bulletin No. A34/56N-32-112.

This Service Bulletin introduces a general visual inspection of all A340-500/600 drag stay lower-arms

which are over 45 months in service from the first installation on an aircraft or from the last NLG

overhaul.

The inspection of the drag stay lower-arm in accordance with this Service Bulletin will detect corrosion

and thus prevent possible failure of the lower-arm.

NOTE: Service Bulletin A340-32-5101 (modification No. 200785H16415) cancels the

requirements of this Service Bulletin.

IF ARM IS 60-72 MONTHS OLD INSPECT WITHIN 5 MONTHS, BUT PRIOR TO 75

MONTHS

IF ARM IS 72-84 MONTHS OLD INSPECT WITHIN 3 MONTHS, BUT PRIOR TO 85

MONTHS

IF ARM IS ABOVE 84 MONTHS OLD INSPECT WITHIN 1 MONTH

IF CORROSION IS DISCOVERED, THE DRAG STAY LOWER ARM SHALL BE REPLACED BY A

NEW OR SERVICEABLE ONE AND THE SAME INSPECTION CARRIED OUT AT A NEW

THRESHOLD NOT TO EXCEED 45 MONTHS SINCE THIS REPLACEMENT.

IF NO RUST TRACES ARE FOUND, THE AIRCRAFT SHOULD BE RETURNED TO SERVICE, AND

THE SAME INSPECTION DONE AT INTERVALS NOT TO EXCEED 6 MONTHS.

TABLE 1

After accomplishment of this Service Bulletin the activities that follow must be done:

- If corrosion traces are discovered and confirmed external to the arm lug/bearing

race interface, the lower drag stay arm must be removed, and replaced with a new

or serviceable part. The timeframe for removal is dependent on the status of the

arm:

. for arms younger than 65 months old**, or arms older than 64 months** which

have had a repeat inspection performed (no more than 6 months since previous

inspection) - 3 months

. for arms between 65 and 85 months old*, which have not had an inspection

within the previous 6 months - 1 month

. for arms older than 85 months*, which have not had an inspection within the

previous 6 months - five flights permitted to allow the aircraft to return to base

for replacement.

NOTE: *drag stay lower arm ages to be measured from the first installation on

an aircraft or from the last NLG overhaul.

NOTE: **drag stay lower arm ages to be measured from the first installation on

an aircraft or from the last NLG overhaul or from part replacement.

Accomplishment of this Service Bulletin is expected to be rendered mandatory by the

issue of an Airworthiness Directive (AD) published by the European Aviation Safety

Agency (EASA). It is anticipated that the AD will confirm the (thresholds and/or intervals

and/or date) given above but reference should be made to the AD for confirmation of the

mandated accomplishment timescale.

F. APPROVAL

Approved under EASA Design Organisation Approval No. EASA 21J.031.

If an aircraft listed in the effectivity has a modification or repair embodied that is not of

AIRBUS origin, and which affects the content of this Service Bulletin, the operator is

responsible for obtaining approval by its airworthiness authority for any adaptation necessary

before incorporation of the Service Bulletin.

WARNING: MAKE SURE THAT YOU OBEY ALL THE WARNINGS AND ALL THE CAUTIONS

INCLUDED IN THE REFERENCED PROCEDURES.

CAUTION: ALWAYS OBEY THE PRECAUTIONS THAT FOLLOW TO KEEP

ELECTRICAL WIRING IN A SATISFACTORY CONDITION (ELECTRICALLY

AND MECHANICALLY SERVICEABLE). WHEN YOU DO MAINTENANCE

WORK, REPAIRS OR MODIFICATIONS, ALWAYS KEEP ELECTRICAL WIRING,

COMPONENTS AND THE WORK AREA AS CLEAN AS POSSIBLE. TO DO

THIS:

- PUT PROTECTION, SUCH AS PLASTIC SHEETING, CLOTHS, ETC; AS

NECESSARY ON WIRING AND COMPONENTS

- REGULARLY REMOVE ALL SHAVINGS, UNWANTED MATERIAL AND

OTHER CONTAMINATION.

THESE PRECAUTIONS WILL DECREASE THE RISK OF CONTAMINATION

AND DAMAGE TO THE ELECTRICAL WIRING INSTALLATION.

IF THERE IS CONTAMINATION, REFER TO ESPM 20-55-00, CLEANING.
