### 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 had 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. The equivalent of 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 MLG Rib 6. NOTE: This Inspection is applicable to all A340-500/600 aircraft. This includes aircraft that are Pre and Post Mod. No. 50040H14762 (Service Bulletin No. A340-57-5008) and Pre and Post Production Mod. No. 51585H14763, and aircraft that are Pre and Post Repair Instruction R57546002 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 MLG-Wing Rib 6 will be identified. The maintenance consequences of this Service Bulletin are the repetitive inspection requirements.

D. DESCRIPTION To accomplish this Service Bulletin it is necessary to : Task 575009-832-895-001: Inspection (1) Do a Detailed Inspection of the FWD and AFT Lugs of the LH and RH MLG-Wing Rib 6 E. COMPLIANCE (1) Classification MANDATORY: Service Bulletin must be accomplished. (2) Accomplishment Timescale The DI of the FWD and AFT Lugs is mandatory at the threshold of 42 months from the first flight. For aircraft older than 42 months that have not had a DI of the FWD and AFT Lugs a Grace period of 4 months can be applied. (1) Perform a detailed inspection of the LH and RH Wing MLG Rib 6 FWD and AFT bearing lugs to detect any cracks. (2) If no crack is detected, repeat the inspection within the following intervals: Inspection interval, whichever occurs first: Model (series): Flight Cycles (FC) Flight Hours (FH) Threshold (months): Grace period (months): A340-500 100 500 42 4 A340-600 100 500 42 4 NOTE: If any crack is detected during the inspection required by (1) or (2), contact AIRBUS immediately and before next flight, replace the cracked MLG Rib 6 fitting. Replacement of the MLG Rib 6 fitting does not constitute terminating action for the repetitive inspection requirements. However if a new gear rib has been installed then the first inspection is to be performed within 42 months. This Service Bulletin has been classified Mandatory by the issue of an Airworthiness Directive (AD) published by the European Aviation Safety Agency (EASA). The AD must be used as the reference document for the mandated accomplishment timescale. F. APPROVAL The technical content of this document is approved under the authority of Design Organisation Approval No. EASA.21J.031.

3. ACCOMPLISHMENT INSTRUCTIONS Task 575009-832-895-001 - 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.
