### TITLE: WINGS - INSPECTION OF MAIN LANDING GEAR SUPPORT RIB5 LUGS ON POST SB 57-1118 A/C **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES Corrosion of the Main Landing Gear (MLG) Rib 5 forward lugs is addressed by the production modification 32025J2211. In service aircraft are addressed by the accomplishment of Service Bulletin A320-57-1118 (Mod. No. 32025J2211) to install new increased interference fit bushes. During routine maintenance, two through cracks were found on the Left Hand (LH) side of two MLG Rib 5 forward lugs on A321 aircraft that were previously modified as per Service Bulletin A320-57-1118 under Structural Repair Manual (SRM) limits. The analysis of the first event has shown a sealant discrepancy, that led to water ingress and initiated corrosion, leading to cracking. The investigation of the second case indicates that a remaining defect which was not removed during the repair has started to propagate, resulting in rupture of the lug. In order to maintain Continued Airworthiness of the affected aircraft, repetitive Detailed Inspection requirements have been assessed and are applicable until a new terminating action for cracking is defined. The repeat inspections will make sure that cracks in the inspection area on the forward lug of the MLG rib 5 fitting will be found at an early stage, thus preventing further damage.

(6) Material Effectivity MATERIAL QTY PER A/C SEE NOTES Consumable CMLB01 As required B. CONCURRENT REQUIREMENTS None C. REASON (1) History Corrosion of the Main Landing Gear (MLG) Rib 5 forward lugs is addressed by the production modification 32025J2211. In service aircraft are addressed by the accomplishment of Service Bulletin A320-57-1118 (Mod. No. 32025J2211) to install new increased interference fit bushes. During routine maintenance, two through cracks were found on the Left Hand (LH) side of two MLG Rib 5 forward lugs on A321 aircraft that were previously modified as per Service Bulletin A320-57-1118 under Structural Repair Manual (SRM) limits. The analysis of the first event has shown a sealant discrepancy, that led to water ingress and initiated corrosion, leading to cracking. The investigation of the second case indicates that a remaining defect which was not removed during the repair has started to propagate, resulting in rupture of the lug.
