### TITLE: NACELLES/PYLONS - AFT FIXED FAIRING - INSPECTION ON PYLON AFT FIXED FAIRING UPPER SPAR (AT RIB 11 LOCATION AND BETWEEN RIB 14 AND 15) AND CENTER SPAR (BETWEEN RIB 14 AND 15). **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES After engine start and before departure of a post-mod 33844P8341 A321 aircraft powered by CFM engines, a high level of vibration was reported by the crew on the pylon aft fixed fairing. The Inspection of the aft pylon fixed structure revealed cracks on the upper spar (at RIB 11 location and between RIB 14 and 15) and centre spar (between RIB 14 and 15). The affected structure is fitted on post-mod 33844P8341 CFM aircraft. As several other post-mod 33844P8341 aircraft were reported with cracked aft fixed fairing structures during accomplishment of MPD task ZL 471-01, AOT A54N002-12 has been launched in Oct 2012 to secure the fleet through a detailed inspection to be performed on aft fixed fairing upper spar (at RIB 11 location and between RIB 14 and 15) and centre spar on all post-mod 33844P8341 CFM Single Aisle fleet. This Service Bulletin recommends performing a repetitive detailed inspection for cracks on the upper spar: - between RIB 14 and 15, - at level of RIB 11. Depending on findings, a repair instruction has to be performed followed by an inspection of centre spar and lower area of RIB 11. This Service Bulletin cancels and supersedes AOT A54N002-12 repetitive inspection.

CONCURRENT REQUIREMENTS None C. REASON (1) History After engine start and before departure of a post-mod 33844P8341 A321 aircraft powered by CFM engines, a high level of vibration was reported by the crew on the pylon aft fixed fairing. The Inspection of the aft pylon fixed structure revealed cracks on the upper spar (at RIB 11 location and between RIB 14 and 15) and centre spar (between RIB 14 and 15). The affected structure is fitted on post-mod 33844P8341 CFM aircraft. As several other post-mod 33844P8341 aircraft were reported with cracked aft fixed fairing structures during accomplishment of MPD task ZL 471-01, AOT A54N002-12 has been launched in Oct 2012 to secure the fleet through a detailed inspection to be performed on aft fixed fairing upper spar (at RIB 11 location and between RIB 14 and 15) and centre spar on all post-mod 33844P8341 CFM Single Aisle fleet. (2) Objective/Action This Service Bulletin recommends performing a repetitive detailed inspection for cracks on the upper spar: - between RIB 14 and 15, - at level of RIB 11. Depending on findings, a repair instruction has to be performed followed by an inspection of centre spar and lower area of RIB 11. (3) Advantages This Service Bulletin cancels and supersedes AOT A54N002-12 repetitive inspection. (4) Operational/Maintenance Consequences None

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).

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.
