MODIFICATIONS

None

REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

It has been identified that some Main Landing Gear (MLG) axles may have been subject to abnormal

grinding operations in Messier-Services Asia facilities. These grinding operations may have resulted in

residual stress of the axle sliding tube. The area potentially impacted is where the axle runs into the

brake mounting flange. These abnormal grinding operations have now been discontinued.

Note: All sliding tube SN potentially impacted are listed in ’Appendix 1’ of this Service Bulletin.

This Service Bulletin is published to advise all operators of:

- A319 and A320 aircraft of the issue of MESSIER-BUGATTI-DOWTY Service Bulletin No.

200-32-313

- A321 aircraft of the issue of MESSIER-BUGATTI-DOWTY Service Bulletin No. 201-32-62.

This Service Bulletin is issued to introduce a one time Special Detailed Inspection (SDI) using Rollscan

or Stress-scan test equipment.

Accomplishment of this Service Bulletin will identify and rectify any defective MLG sliding tube axles.

This will prevent further incidents of residual stress occurring and the need for further unnecessary

maintenance and operator downtime.

SERVICE BULLETIN

This Service Bulletin has been classified Recommended. It is expected that an

Airworthiness Directive (AD) published by the European Aviation Safety Agency (EASA)

will be issued to change this classification to Mandatory. 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

The technical content of this document is approved under the authority of Design

Organization 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.

G. MANPOWER

The manpower estimates given in this Service Bulletin are based on the direct labor cost to

do the work. These estimates assume that the work will be done by experienced personnel,

and may need to be revised upwards to suit operator’s circumstances. The estimates do not

include the time to prepare, plan or inspect the work. Manufacture and procurement of parts

and tools, drying times for paints, sealants, etc., and general administration work are also not

included.

The minimum manhours necessary to accomplish this Service Bulletin are those for the

Inspection. Depending on the inspection result, additional manhours can apply.

3. ACCOMPLISHMENT INSTRUCTIONS

Task 321416-832-895-001 - Inspection

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.

NOTE: The accomplishment instructions of this Service Bulletin refer to procedures

included in other AIRBUS documents. When the words ’refer to’ are used and the

operator has an accepted alternative procedure, the accepted alternative procedure

can be used. When the words ’in accordance with’ are included in the instruction,

the procedure in the AIRBUS document must be used.

NOTE: The access and close-up instructions, not comprising return to service tests, in this

Service Bulletin do not constitute or affect the technical intent of the Service

Bulletin. Operators can therefore, as deemed necessary, omit or add access and/or

close-up steps to add flexibility to their maintenance operations as long as the

technical intent of the Service Bulletin is met within the set parameters.

NOTE: Manual titles given in the accomplishment instructions are referred to by acronyms.

Refer to paragraph 1.J., References, for the definition of acronyms.

NOTE: This Service Bulletin is classified mandatory or expected to be classified mandatory

by an Airworthiness Directive (AD). The paragraphs 3.C. and 3.D. in these

accomplishment instructions are Required for Compliance (RC) and must be done

to comply with the AD. Other paragraphs are recommended and may be deviated

from, done as part of other actions or done with accepted methods different from

those given in the Service Bulletin, as long as the RC paragraphs can be done and

the aircraft can be put back into a serviceable condition.

NOTE: The purpose of flow charts is to supplement the information given in the Procedure

and Compliance paragraphs and not to serve as the primary source for tasks or

compliance times given in this Service Bulletin.
