Replace the complete document. Put this Revision Transmittal Sheet in front of the Service Bulletin. HISTORY OF PREVIOUS REVISIONS Revision No. 01 issued to inform the operators of a fuel leak test to be performed in the case of crack detection. This Service Bulletin is rendered mandatory by Airworthiness Directive (Consigne de Navigabilite) No. 97-309-104(B). Revision No. 02 issued to inform the operators of technical changes in the repair procedure. Furthermore, Kits A07R01 and A08R02 are added to include the new parts necessary for this Revision. Revision No. 03 issued to modify the threshold and interval related to the embodiment of this Service Bulletin. The threshold and interval figures indicated in the previous issues of this Service Bulletin have been defined on the basis of full scale fatigue test. Since then, a survey, carried out on the A320 family fleet, has highlighted some differences between the mission parameters of in service aircraft and those 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 and intervals related to the embodiment of this Service Bulletin have been revised and a new limit, expressed in flight hours has been introduced.

### TITLE: WINGS - SECTION 21 - INSPECT LOWER SURFACE PANEL BETWEEN FRAME 41 AND 42. **CONF ALL MODIFICATIONS None 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. Related modification Service Bulletin No. A320-57-1043 (Mod. No. 22418P2408) recommends a shot peening on the affected areas to prevent from crack initiation. However, on aircraft on which modification Service Bulletin No. A320-57-1043 (Mod. No.22418P2408) before revision 06 is accomplished, the shot peening could have been uncorrectly done on the CAA protection, which has no fatigue benefit effect. Therefore, the inspection is required again on these aircraft. Moreover, the repair solution provided on previous revisions of this Inspection Service Bulletin is no more applicable and has been removed from Inspection Service Bulletin A320-57-1082 revision 04. For aircraft on which Modification Service Bulletin No. A320-57-1043 revision 06 or any subsequent revision (Mod. No. 22418P2408) is not accomplished, this Inspection Service Bulletin calls for repetitive High Frequency Eddy Current (HFEC) inspection on the external face of the center wing box lower panel. Accomplishment of this Inspection Service Bulletin will enable detection of cracks at an early stage, thus avoiding further damage on the center wing box lower panel. Accomplishment of this Inspection Service Bulletin is cancelled by accomplishment of the Modification Service Bulletin A320-57-1043 revision 06 or any subsequent revision (Mod. No 22418P2408).

No.22418P2408) before revision 06 is accomplished, the shot peening could have been uncorrectly done on the CAA protection, which has no fatigue benefit effect. Therefore, the inspection is required again on these aircraft. Moreover, the repair solution provided on previous revisions of this Inspection Service Bulletin is no more applicable and has been removed from Inspection Service Bulletin A320-57-1082 revision 04. (2) Objective/Action For aircraft on which Modification Service Bulletin No. A320-57-1043 revision 06 or any subsequent revision (Mod. No. 22418P2408) is not accomplished, this Inspection Service Bulletin calls for repetitive High Frequency Eddy Current (HFEC) inspection on the external face of the center wing box lower panel. (3) Advantages Accomplishment of this Inspection Service Bulletin will enable detection of cracks at an early stage, thus avoiding further damage on the center wing box lower panel. Accomplishment of this Inspection Service Bulletin is cancelled by accomplishment of the Modification Service Bulletin A320-57-1043 revision 06 or any subsequent revision (Mod. No 22418P2408). (4) Operational/Maintenance Consequences None D. DESCRIPTION To accomplish this Service Bulletin it is necessary to : **CONF 001 Task 571082-832-801-001: INSPECTION (1) Do a HFEC Inspection on the Lower Surface Panel of the Center Wing Box **CONF 002 Task 571082-832-801-001: INSPECTION (1) Do a HFEC Inspection on the Lower Surface Panel of the Center Wing Box

3. ACCOMPLISHMENT INSTRUCTIONS Task 571082-832-801-001 - 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. NOTE: The purpose of flow charts is to supplement the information given in the Procedure and Compliance paragraphs and not to serve as the primary source for tasks or compliance times given in this Service Bulletin.
