### TITLE: POWER PLANT - GENERAL - WRONG AFT MOUNT TORQUE VALUE FOR ENGINES CFM56-5A IN AMM 71-00-00-400-040-A01 **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES In the May 2013 AMM revision, an incorrect AFT pylon bolt torque value was introduced in AMM Task 71-00-00-400-040-A01 "Installation of the Power Plant with Engine Positioner TWW 75E" used only for CFM56-5A engine model. The correct torque value to be mentioned in this AMM Task should be 65.08-78.64 m.daN (480-580 lbf.ft) whereas it mentioned 43.39-47.45 m.daN (320-350 lbf.ft) in the May 2013 AMM revision. This AMM Task has been corrected to reflect the correct torque value for AFT engine mounts in the May 2014 AMM revision. Pending availability of the AMM correction, a Temporary Revision (TR) 71-030 with correct information is available since Mar 14/14. The aim of this Service Bulletin is to re-torque the affected bolts at correct level to assure the proper assembly performance and comply with current fatigue and damage tolerance certification requirements. Accomplishment of this Service Bulletin will contribute to avoid pylon bolts and beam holes frettingdamages and joint separation which would decrease their fatigue life and make the pylon bolts noncompliant with certified maintenance program.

# @A318/A319/A320/A321 SERVICE BULLETIN (5) Configuration definition **CONF 001 Config. 001 is valid for all the aircraft given in the effectivity of this Service Bulletin as a standard configuration. (6) Material Effectivity No Material Set B. CONCURRENT REQUIREMENTS None C. REASON (1) History In the May 2013 AMM revision, an incorrect AFT pylon bolt torque value was introduced in AMM Task 71-00-00-400-040-A01 "Installation of the Power Plant with Engine Positioner TWW 75E" used only for CFM56-5A engine model. The correct torque value to be mentioned in this AMM Task should be 65.08-78.64 m.daN (480-580 lbf.ft) whereas it mentioned 43.39-47.45 m.daN (320-350 lbf.ft) in the May 2013 AMM revision. This AMM Task has been corrected to reflect the correct torque value for AFT engine mounts in the May 2014 AMM revision. Pending availability of the AMM correction, a Temporary Revision (TR) 71-030 with correct information is available since Mar 14/14. (2) Objective/Action The aim of this Service Bulletin is to re-torque the affected bolts at correct level to assure the proper assembly performance and comply with current fatigue and damage tolerance certification requirements. (3) Advantages Accomplishment of this Service Bulletin will contribute to avoid pylon bolts and beam holes fretting damages and joint separation which would decrease their fatigue life and make the pylon bolts non-compliant with certified maintenance program. (4) Operational/Maintenance Consequences None D.

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 Aviati on Safety Agency (EASA) will be issued to change this classification to Mandatory. It is anticipated that the AD will confirm the threshold given but reference should be made to the AD for confirmation of the mandated accomplishment timescale.

F. APPROVAL The technical content of this document is approved under the authority of Design Organization Approval No. EASA. 21J.031. If an aircraft listed in the effectivity 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 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.

3. ACCOMPLISHMENT INSTRUCTIONS Task 711063-832-801-001 - Inspection of the AFT Engine Mount Pylon Bolts (FINs 1000EM1 and 1000EM2) 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 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. NOTE : The accomplishment instructions of this Service Bulletin include procedures given in other documents or in other sections of the Service Bulletin. When the words "refer to" are used and the operator has a procedure accepted by the local authority he belongs to, the accepted alternative procedure can be used. When the words "in accordance with" are used then the given procedure must be followed. 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.
