### TITLE: LANDING GEAR - NOSE GEAR - ADDITION OF PRIMER PAINT TO THE CADMIUM AROUND THE DOWEL BUSH HOLES ON THE MAIN FITTING **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR 200616H16400 MINOR None 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 Corrosion has been found on the main fitting of the NLG leg in the vicinity of the dowel pin bushes retaining the lower steering flange on 15 A330/A340 aircraft. The majority of parts have been reworked and returned to service. Due to the potential consequence of the failure of the NLG leg main fitting, the widespread occurrence of the corrosion throughout the A330/A340 fleet and the lack of opportunity for detection on certain aircraft other than overhaul, modifications are required to eliminate the root cause of the corrosion. This Service Bulletin is published to advise all operators of A340 aircraft of the issue of MESSIERDOWTY Service Bulletin No. D23581-32-066. MESSIER-DOWTY Service Bulletin No. D23581-32-066 is a cover Service Bulletin and introduces MESSIER-DOWTY Service Bulletin No. D23581-32-064 and MESSIER-DOWTY Service Bulletin No. D23581-32-065. This Service Bulletin (in conjunction with MESSIER-DOWTY Service Bulletin No. D23581-32-064) introduces paint to the bare cadmium around the dowel hole in order to provide further protection against cadmium degradation that is the root cause of the corrosion found in this area of the main fitting.

SERVICE BULLETIN
Due to the potential consequence of the failure of the NLG leg main fitting, the widespread occurrence of the corrosion throughout the A330/A340 fleet and the lack of opportunity for detection on certain aircraft other than overhaul, modifications are required to eliminate the root cause of the corrosion. (2) Objective/Action This Service Bulletin is published to advise all operators of A340 aircraft of the issue of MESSIER-DOWTY Service Bulletin No. D23581-32-066. MESSIER-DOWTY Service Bulletin No. D23581-32-066 is a cover Service Bulletin and introduces MESSIERDOWTY Service Bulletin No. D23581-32-064 and MESSIER-DOWTY Service Bulletin No. D23581-32-065. This Service Bulletin (in conjunction with MESSIER-DOWTY Service Bulletin No. D23581-32-064) introduces paint to the bare cadmium around the dowel hole in order to provide further protection against cadmium degradation that is the root cause of the corrosion found in this area of the main fitting. (3) Advantages Accomplishment of this Service Bulletin, together with Service Bulletin A340-32-4283 (Mod. No. 200615H16360) (in conjunction with MESSIER-DOWTY Service Bulletin No. D23581-32-065), will make sure that no corrosion exists in the vicinity of the dowel pin bushes and the likelihood of further corrosion in the area will be reduced to an absolute minimum. NOTE: Service Bulletin A340-32-4283 (Mod. No. 200615H16360) (in conjunction with MESSIER-DOWTY Service Bulletin No. D23581-32-065), introduces an amended interference fit between the bronze bushes and the steel (300M) main fitting and amends the bush material from UZ19A6 to C63020. (4) Operational/Maintenance Consequences The NLG main fitting, Primary Structural Element (PSE), part number change will be introduced into the ALS Part 1 at the next scheduled revision. D. DESCRIPTION To accomplish this Service Bulletin it is necessary to : **CONF 001 Task 324282-831-895-001: MODIFICATION (1) REMOVE NLG/RNLG LEG COMPONENTS (2) MODIFY THE NLG/RNLG (3) INSTALL THE NLG/RNLG LEG COMPONENTS (4) RE-IDENTIFY THE NLG LEG AND MAIN FITTING/SHOCK ABSORBER
