### TITLE: WINGS - STRUCTURE - INSPECTION OF MAIN LANDING GEAR SUPPORT RIB 5 LUGS **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES During routine maintenance, two A321 aircraft Left Hand (LH) Main Landing Gear (MLG) Rib 5 forward lugs were found ruptured. These had been previously modified as per Service Bulletin A320-57-1118 under Structural Repair Manual limits (Ref. ARS 57-0029). The analysis of the first event has shown that a sealant discrepancy had led to water ingress and then initiated corrosion, leading to cracking. The investigation of the second event has shown that a remaining defect which was not removed during the repair had propagated, resulting in rupture of the lug. In order to maintain Continued Airworthiness of Single Aisle aircraft, a repetitive Detailed Visual Inspection is introduced by Rev. 01 to Service Bulletin A320-57-1166 for all modified and/or repaired aircraft. Due to the similarity between MLG Rib 5 on A310 aircraft and that of the A320 aircraft family (same design principle for the lug, same material, same modification or repair principles), a repetitive Detailed Visual Inspection (DVI) or Ultrasonic Inspection (SDET) is also introduced by this Service Bulletin for Gear Rib 5 lugs: - Modified by Service Bulletin A310-57-2090 Rev. 00 to 02 - Repaired by Repair Instruction R57249121 Issue A to D. This repetitive inspection will maintain Airworthiness of all aircraft modified by Service Bulletin and/or repaired by Repair Instruction.

C. REASON (1) History During routine maintenance, two A321 aircraft Left Hand (LH) Main Landing Gear (MLG) Rib 5 forward lugs were found ruptured. These had been previously modified as per Service Bulletin A320-57-1118 under Structural Repair Manual limits (Ref. ARS 57-0029). The analysis of the first event has shown that a sealant discrepancy had led to water ingress and then initiated corrosion, leading to cracking. The investigation of the second event has shown that a remaining defect which was not removed during the repair had propagated, resulting in rupture of the lug. (2) Objective/Action In order to maintain Continued Airworthiness of Single Aisle aircraft, a repetitive Detailed Visual Inspection is introduced by Rev. 01 to Service Bulletin A320-57-1166 for all modified and/or repaired aircraft. Due to the similarity between MLG Rib 5 on A310 aircraft and that of the A320 aircraft family (same design principle for the lug, same material, same modification or repair principles), a repetitive Detailed Visual Inspection (DVI) or Ultrasonic Inspection (SDET) is also introduced by this Service Bulletin for Gear Rib 5 lugs: - Modified by Service Bulletin A310-57-2090 Rev. 00 to 02 - Repaired by Repair Instruction R57249121 Issue A to D. (3) Advantages This repetitive inspection will maintain Airworthiness of all aircraft modified by Service Bulletin and/or repaired by Repair Instruction. (4) Operational/Maintenance Consequences None D. DESCRIPTION NOTE: Operators have a choice to perform either a Detailed Visual Inspection (DVI) or an Ultrasonic Inspection (SDET). Refer to the two separate tasks for each Method. To accomplish this Service Bulletin it is necessary to : Task 572101-832-895-001: METHOD 1 - DETAILED VISUAL INSPECTION (DVI) (1) Do a Detailed Visual Inspection (DVI) Task 572101-832-896-001: METHOD 2 - ULTRASONIC INSPECTION (SDET) (1) Do an Ultrasonic Inspection (SDET)

E. COMPLIANCE (1) Classification MANDATORY: Service Bulletin must be accomplished. (2) Accomplishment Timescale Threshold (since Modification/repair embodiment): 2500 Flight Cycles (FC) Interval for Detailed Visual Inspection (DVI), repetitive inspection: 775 FC Interval for Ultrasonic Inspection (SDET), repetitive inspection: 1,300 For aircraft having exceeded the threshold, a grace period is permitted: 775 FC 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 and/or intervals and/or date) given above but reference should be made to the AD for confirmation of the mandated accomplishment timescale. F. APPROVAL The technical content of this document is approved under the authority of Design Organization Approval No. EASA.21J.031. If an aircraft listed in the effectivity has a modification or repair embodied that is not of AIRBUS origin, and which affects the content of this Service Bulletin, the operator is responsible for obtaining approval by its airworthiness authority for any adaptation necessary before incorporation of the Service Bulletin. 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.
