# @A318/A319/A320/A321 SERVICE BULLETIN REVISION TRANSMITTAL SHEET HISTORY OF PREVIOUS REVISIONS Revision No. 01 issued to include changes in effectivity, address of supplier FISHER and incorporate Change Notice No. 0.A. Revision No. 02 issued to modify Figure 2, incorporate Change Notice No.1.A. and update the effectivity. Revision No. 03 issued to delete notes about MRB and include a HFEC inspection procedure before shot peening. Revision No. 04 issued to add preparation operations before modification and test operations after modification. Moreover, the shot peening areas have been reduced to avoid removal of fasteners and hydraulic pump support. Revision No. 05 issued to modify the threshold related to the embodiment of this Service Bulletin. The threshold figure indicated in the previous issues of this Service Bulletin has been defined on the basis of full scale fatigue tests. Since then, a survey, carried out on the A320 family fleet, has highlighted some differences between the mission parameters of in-service aircraft andthose initially considered.The differences are mainly on the weight of fuel at landing and on the average flight time which are higher than those defined for the analysis of the fatigue related tasks.This has led to an adjustment of the A320 family reference fatigue mission. Consequently, the threshold related to the embodiment of this Service Bulletin has been revised and a new limit, expressed in flight hours, has been introduced.

### TITLE: WINGS - SECTION 21 - INTRODUCE SHOT PEENING ON LOWER SURFACE PANEL **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR None MINOR 22418P2408 NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics affecting the airworthiness of the product. All other changes are major changes. REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES During full scale fatigue tests, cracks were detected on the center wing box lower panel, in the radius of the milling step between stiffener 13 and 14 near the fuel pump aperture. Embodiment of Modification Service Bulletin No. A320-57-1043 up to revision 05 could lead to shot peening on Chromic Acid Anodized layer (CAA) protection with no fatigue benefit effect. Therefore, in case of Modification Service Bulletin No. A320-57-1043 was accomplished before revision 06, an inspection is still required as per Inspection Service Bulletin No. A320-57-1082. In order to cancel Inspection Service Bulletin No. A320-57-1082 requirements, the Modification Service Bulletin No. A320-57-1043 at revision 06 has to be accomplished. This will ensure required removal of the CAA protection prior application of the shot peening procedure. To avoid possible crack initiation and subsequent extensive repair on the lower panel, this Modification Service Bulletin recommends introduction of shot peening in the radius of the milling step between stiffener 13 and 14 near the fuel pump aperture. Accomplishment of this Service Bulletin at revision No. 06 cancels the inspection requirements of Service Bulletin No. A320-57-1082.

REASON (1) History During full scale fatigue tests, cracks were detected on the center wing box lower panel, in the radius of the milling step between stiffener 13 and 14 near the fuel pump aperture. Embodiment of Modification Service Bulletin No. A320-57-1043 up to revision 05 could lead to shot peening on Chromic Acid Anodized layer (CAA) protection with no fatigue benefit effect. Therefore, in case of Modification Service Bulletin No. A320-57-1043 was accomplished before revision 06, an inspection is still required as per Inspection Service Bulletin No. A320-57-1082. In order to cancel Inspection Service Bulletin No. A320-57-1082 requirements, the Modification Service Bulletin No. A320-57-1043 at revision 06 has to be accomplished. This will ensure required removal of the CAA protection prior application of the shot peening procedure.

3. ACCOMPLISHMENT INSTRUCTIONS Task 571043-831-801-001 - Modification 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. IN CASE OF 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.
