### TITLE: WINGS - MAIN LANDING GEAR ATTACHMENT - DETAILED INSPECTION OF THE MLG RIB 6 FWD AND AFT LUGS **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES During Main Landing Gear (MLG) lubrication, a crack has been visually found on the FWD Lug of the Wing MLG Rib 6 on an A330 in-service aircraft. This aircraft was Pre Mod. No. 49353H14087 (Service Bulletin No. A330-57-3082) and had accumulated 3,638 Flight Cycles (FC) and 25,469 Flight Hours (FH) at the time of finding. The crack has extended through the entire thickness of the FWD Lug, at approximately the 4 o’clock position (when looking forward). Subsequently, several cases have been reported on A330/A340 aircraft. This Service Bulletin has been validated on A340 aircraft MSN 0402. The objective of this Inspection Service Bulletin is to introduce a repetitive Detailed Inspection (DI) to detect for any cracks on the FWD and AFT Lugs of the LH and RH Wing MLG Rib 6. NOTE: This Inspection is applicable to all A340 aircraft. This includes aircraft that are Pre and Post Mod. No. 49353H14087 (Service Bulletin No. A340-57-4088) and aircraft that are Pre and Post Repair Instruction R57256230 or Repair Instruction R57256266 or SRM 57-26-13. The accomplishment of this Service Bulletin introduces repeat inspections that will ensure that any through cracks on the FWD and AFT Lugs of the LH and RH Wing MLG Rib 6 will be identified. The maintenance consequences of this Service Bulletin are the repetitive inspection requirements.

3. ACCOMPLISHMENT INSTRUCTIONS Task 574104-832-895-001 - 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.
