### TITLE: LANDING GEAR - NOSE GEAR - INSPECTION AND OVERHAUL OF NOSE LANDING GEAR RETRACTION ACTUATOR P/N D23352000 SERIES **CONF ALL MODIFICATIONS None 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 theeye-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.

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.

# @A340 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 with in 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. COMPLIANCE TIME ACTION THRESHOLD GRACE PERIOD REPETITIVE INTERVAL NOT TO EXCEED If the NLG retraction actuator has accumulated more than 8 years but less than 14 years from its first flight on an aircraft, from the issue date of this Inspection Service Bulletin Within 24 months from the issue date of this Inspection Service Bulletin but before 15 years from the NLG retraction actuator’s first flight on an aircraft Overhaul the NLG Retraction Actuator in accordance with the Service Bulletin, CMM 32-33-30 and the Messier Dowty Service Bulletin No. D23581-32-051 At the accumulation of 10 years from the NLG retraction actuator’s first flight on an aircraft or from the first flight after its last overhaul in accordance with the CMM 32-33-30 and the Messier Dowty Service Bulletin No. D23581-32-051, as applicable If the NLG retraction actuator has accumulated 14 years or more from its first flight on an aircraft, at the issue date of this Inspection Service Bulletin Within 12 months after the issue date of this Inspection Service Bulletin Every 10 years from the retraction actuator’s first flight since its last overhaul
