### TITLE: POWER PLANT - GENERAL - FORWARD MOUNT - INSPECTION OF FORWARD ENGINE MOUNT **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES Manufacturing metallurgical discontinuities have been reported on one identified batch of forward engine mount crossbeam attach pins PN 740-2022-501 fitted on A320 aircraft family powered by IAE V2500 Engine. Investigations concluded this defect could generate a stress concentration leading to an adverse effect on the fatigue life, therefore all identified attach pins manufactured from the discrepant raw material are subject to replacement. This Inspection Service Bulletin is published to advise all operators of A320 aicraft powered by IAE V2500 Engines of the issue of UTAS Service Bulletin No. V2500-NAC-71-0323. This Inspection Service Bulletin provides instructions for a onetime detailed visual inspection to check the serial number (SN) of the forward engine mount crossbeam to main beam attach pins P/N 740-2022-501 and to remove and replace the affected attach pi ns which are listed in the VSB. Accomplishment of this Inspection Service Bulletin will enable the replacement of the affected attach pins and thus restoring the part structural design objective.

3. ACCOMPLISHMENT INSTRUCTIONS Task 711064-832-801-001 - Inspection of the Serial Number (SN) of the Forward Engine Mount Crossbeam Attach Pin for Engines 1 and 2 in accordance with VSB 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 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.
