REASON ### Page 3 A318/A319/A320/A321 SERVICE BULLETIN SUMMARY REV 00 Nov 21/19 A320-57-1228 Page 3 (1) History In order to comply with the new regulations for widespread fatigue damage requirements, a modification is needed at the Center Wing Box (CWB) area, reinforcing the junction between floor beams and vertical stringers at Frame 36 front spar. This modification only concerns A318/A319/A320 aircraft pre-MOD No. 160000P11994, A321 aircraft pre-MOD No. 160021J3446 and A319/A320 aircraft pre-MOD No. 160080J3705 (pre- Ref. SB A320-57-1193). (2) Objective/Action For the aircraft listed in the applicability, accomplishment of this Service Bulletin consists in: - Replacing the forward end of the longitudinal floor beams on the CWB top skin panel by a reinforced one (with additional splices and shims installed) - Replacing the front spar vertical stringers by an identical one and applying new holes sizes at the floor beam/stringer junction. Prior to Service Bulletin accomplishment, specific attention must be paid to the preparation, refer to paragraph 3.B Preparation. (3) Advantages Accomplishment of this Service Bulletin will contribute to the structural integrity of the junction between floor beams and vertical stringers at Frame 36 front spar. Accomplishment of this Service Bulletin cancels the requirements of Ref. SB A320-57-1178. (4) Operational/Maintenance Consequences None C.

CONF 004 retrofits following modifications: 164698P20635. CONF ALL B. CONCURRENT REQUIREMENTS None C. REASON (1) History In order to comply with the new regulations for widespread fatigue damage requirements, a modification is needed at the Center Wing Box (CWB) area, reinforcing the junction between floor beams and vertical stringers at Frame 36 front spar. This modification only concerns A318/A319/A320 aircraft pre-MOD No. 160000P11994, A321 aircraft pre-MOD No. 160021J3446 and A319/A320 aircraft pre-MOD No. 160080J3705 (pre- Ref. SB A320-57-1193). (2) Objective/Action For the aircraft listed in the applicability, accomplishment of this Service Bulletin consists in: - Replacing the forward end of the longitudinal floor beams on the CWB top skin panel by a reinforced one (with additional splices and shims installed) - Replacing the front spar vertical stringers by an identical one and applying new holes sizes at the floor beam/stringer junction. Prior to Service Bulletin accomplishment, specific attention must be paid to the preparation, refer to paragraph 3.B Preparation. (3) Advantages Accomplishment of this Service Bulletin will contribute to the structural integrity of the junction between floor beams and vertical stringers at Frame 36 front spar. Accomplishment of this Service Bulletin cancels the requirements of Ref. SB A320-57-1178. (4) Operational/Maintenance Consequences None D.

Y-1292 at FR36 CONF ALL E. COMPLIANCE (1) Classification RECOMMENDED: Service Bulletin recommended to be accomplished to prevent significant operational disruptions. (2) Accomplishment Timescale This Service Bulletin has been classified Recommended. It is expected that an Airworthiness Directive (AD) published by the European Aviation Safety Agency (EASA) will be issued to change this classification to Mandatory. It is anticipated that the AD will confirm the thresholds given but reference should be made to the AD for confirmation of the mandated accomplishment timescale. It is expected that an AD will be issued in case of Maintenance Program Publication Trigger (MPPT) extension. The compliance timescales are as follows: - For A318/A319/A320 aircraft: before reaching 72000 Flight Cycles (FC) or 144000 Flight Hours (FH) from aircraft first flight, but not before reaching 30000 FC or 60000 FH from aircraft first flight. - For A321 aircraft: before reaching 66724 FC or 133448 FH from aircraft first flight, but not before reaching 34000 FC or 68000 FH from aircraft first flight. F. APPROVAL The technical content of this document is approved under the authority of Design Organisation Approval No. EASA.21J.031. If an aircraft listed in the applicability 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 CONF 001 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.
