REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

An A330 aircraft experienced an in-flight turn back due to inability to retract the Nose Landing Gear

(NLG). Subsequent investigation revealed that the eye-end fitting of the NLG retraction actuator (FIN

5201GA) was detached from the piston rod of the retraction actuator. Both the male threads of the

eye-end and the female threads of the piston rod were almost completely stripped and evidence of

corrosion was also found on both of these parts. The retraction actuator was over 10 years old and had

not been overhauled.

As Long Range model families are of similar type design, the above conditions also exist on the model

family addressed in this Service Bulletin.

This Service Bulletin details an inspection and overhaul of the affected retraction actuators.

Inspection and overhaul of affected retraction actuators in accordance with this Service Bulletin will

make sure that corroded parts are not fitted to the NLG retraction actuator. Thus the possibility of the

eye-end of the retraction actuator becoming detached due to corrosion will be avoided. Subsequent inflight turn back due to inability to retract the NLG will also be avoided.

SERVICE BULLETIN

C. REASON

(1) History

An A330 aircraft experienced an in-flight turn back due to inability to retract the Nose

Landing Gear (NLG). Subsequent investigation revealed that the eye-end fitting of the

NLG retraction actuator (FIN 5201GA) was detached from the piston rod of the retraction

actuator. Both the male threads of the eye-end and the female threads of the piston rod

were almost completely stripped and evidence of corrosion was also found on both of

these parts. The retraction actuator was over 10 years old and had not been overhauled.

As Long Range model families are of similar type design, the above conditions also exist

on the model family addressed in this Service Bulletin.

(2) Objective/Action

This Service Bulletin details an inspection and overhaul of the affected retraction

actuators.

(3) Advantages

Inspection and overhaul of affected retraction actuators in accordance with this Service

Bulletin will make sure that corroded parts are not fitted to the NLG retraction actuator.

Thus the possibility of the eye-end of the retraction actuator becoming detached due to

corrosion will be avoided. Subsequent in-flight turn back due to inability to retract the

NLG will also be avoided.

(4) Operational/Maintenance Consequences

None

D. DESCRIPTION

To accomplish this Service Bulletin it is necessary to :

Task 324291-832-895-001: INSPECTION

(1) Check of the PN of the NLG Retraction Actuator

(2) Remove the NLG Retraction Actuator

(3) Inspect and Overhaul the NLG Retraction Actuator

(4) Install the NLG Retraction Actuator

E. COMPLIANCE

SERVICE BULLETIN

(2) Accomplishment Timescale

To make sure of the continued airworthiness of the A340 fleet, the inspection/overhaul

and timescale detailed in Table 1 is necessary.

To ensure availability of retraction actuator component parts, operators are requested to

complete the planning proforma, Appendix 02, and return it to AIRBUS SEEL3 dept. and

MESSIER-DOWTY within 2 months of Service Bulletin issuance.

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

Directive (AD) published by the European Aviation Safety Agency (EASA) will be issued

to confirm this classification. It is anticipated that the AD will confirm the thresholds

given above but reference should be made to the AD for confirmation of the mandated

accomplishment timescale.

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 324291-832-895-001 - 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.
