MODIFICATIONS

MODIFICATION CLASSIFICATION
MAJOR None
MINOR 152540J3374

NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the
mass, balance, structural strength, reliability, operational characteristics affecting the
airworthiness of the product. All other changes are major changes.

REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

The Nose Landing Gear (NLG) Part Number (PN) is defined by a combination of hydraulic power
source, structural capabilities, type of servicing and other options available. This led to 27 NLG PN
families with limited interchangeability possibilities between each other despite technical feasibility.

This modification provides instructions for the NLG leg assembly to be administratively separated into
four Line Replaceable Units (LRU’s). The current NLG leg assembly FIN 2526GM will be split as
follows:

- LRU FIN 2881GM - Leg Assy NLG, Non-Customized

- LRU FIN 2880GM - Spring Curve Customization

- LRU FIN 2879GM - Hydraulic System Customization

- LRU FIN 2878GM - Tire Pressure Indicating System (TPIS) Customization.

This will allow the modification of LRU’s without a change to the NLG leg assembly PN.

Additionally, to facilitate the merging of NLG leg PN’s into the minimum number of common legs and to
allow maximum flexibility with the different versions of LRU’s, this modification introduces:

- NLG leg assy parts for commonality (Lower torque link stop block, Intermediate harness protection
covers and clamping support)

SERVICE BULLETIN
SUMMARY

- New Servicing Plate design and location

- 2 new identification placards for Leg Structure and Leg Dressing assemblies

- Modification of the harness looms dedicated to the Weight and Balance System, if installed.

No interfaces with the aircraft are affected by this modification.

This Service Bulletin is published to advise all operators of A320 aircraft family of the issue of
MESSIER-BUGATTI-DOWTY Service Bulletin No. 580-32-3173.

After accomplishment of this SB operators will have increased possibility of interchange between NLG
legs, independently of the hydraulic system power source, Tyre Pressure Indicating System (TPIS)
status and servicing chart.

**CONF ALL

B. CONCURRENT REQUIREMENTS

None

C. REASON

(1) History

The Nose Landing Gear (NLG) Part Number (PN) is defined by a combination of
hydraulic power source, structural capabilities, type of servicing and other options
available. This led to 27 NLG PN families with limited interchangeability possibilities
between each other despite technical feasibility.

(2) Objective/Action

This modification provides instructions for the NLG leg assembly to be administratively
separated into four Line Replaceable Units (LRU’s). The current NLG leg assembly FIN
2526GM will be split as follows:

- LRU FIN 2881GM - Leg Assy NLG, Non-Customized

- LRU FIN 2880GM - Spring Curve Customization

- LRU FIN 2879GM - Hydraulic System Customization

- LRU FIN 2878GM - Tire Pressure Indicating System (TPIS) Customization.

This will allow the modification of LRU’s without a change to the NLG leg assembly PN.

Additionally, to facilitate the merging of NLG leg PN’s into the minimum number of
common legs and to allow maximum flexibility with the different versions of LRU’s, this
modification introduces:

- NLG leg assy parts for commonality (Lower torque link stop block, Intermediate
harness protection covers and clamping support)

- New Servicing Plate design and location

- 2 new identification placards for Leg Structure and Leg Dressing assemblies

- Modification of the harness looms dedicated to the Weight and Balance System, if
installed.

No interfaces with the aircraft are affected by this modification.

This Service Bulletin is published to advise all operators of A320 aircraft family of the
issue of MESSIER-BUGATTI-DOWTY Service Bulletin No. 580-32-3173.

(3) Advantages

After accomplishment of this SB operators will have increased possibility of interchange

between NLG legs, independently of the hydraulic system power source, Tyre Pressure
Indicating System (TPIS) status and servicing chart.

(4) Operational/Maintenance Consequences

None

D. DESCRIPTION

The accomplishment instructions are divided into two tasks to give the operator the option of
accomplishment on aircraft or accomplishment on bench.

To accomplish this Service Bulletin it is necessary to :

E. COMPLIANCE

(1) Classification

RECOMMENDED: Service Bulletin recommended to be accomplished to prevent

significant operational disruptions.

(2) Accomplishment Timescale

Accomplishment of this Service Bulletin is recommended at the earliest opportunity

where manpower and facilities are available.

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.

Task 321392-831-895-001 - MODIFICATION ON AIRCRAFT

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,

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: 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.
