Due to vibration, cracks have been found to occur in the bracket and the metallic strap has been found to be missing. This can cause chafing of the wiring loom on the aircraft structure.This modification installs a new metallic bracket with electrical bonding, reinforced clamp and strap to replace the existing parts at the first attachment point in the wing after each inboard pylon in the LH and RH wings.Accomplishment of this EO will improve the wiring installation in the wing/pylon area to prevent chafing, possible short circuits and damage to systems.Issued this EO to be modified.R01 增加支架安装孔视情处理等步骤，更正Figure A-GBAAA等。R01 add work steps to rework the holes in bracket, correct Figure A-GBAAA.TOOLS/工具TOOLS NECESSARY/必须工具ITEM项目P/N件号DESCRIPTION名称EQTP类型QTY数量APP适用性Conditions note互换信息及备注TOOLS IF NECESSARY/视情工具ITEM项目P/N件号DESCRIPTION名称EQTP类型QTY数量APP适用性Conditions note互换信息及备注PARTS AND MATERIAL/航材NOTE:OPERATOR MUST GET AND INSTALL THE PARTS THAT CORRESPOND TO THE RELATIVE WORKORDER NO.注释：请工作者严格按照工作指令号领取预定的航材装机PARTS AND MATERIAL NECESSARY/必须航材ITEM项目P/N件号DESCRIPTION名称EQTP类型QTY数量APP适用性Conditions note互换信息及备注1CML19-003CLEANING ABSORCH1ALL按需2CML11-016CLEANING SOLVENTCH1ALL按需/08BPA13CML09-007BRUSHABLE FUEL RESISTANT COATINGCH1ALL按需4CML07-001BELECTRICAL BOND VARNISHCH1ALL按需5923132D01R01KITAS1ALLN/APARTS AND MATERIALIF NECESSARY/视情航材ITEM项目P/N件号DESCRIPTION名称EQTP类型QTY数量APP适用性Conditions note互换信息及备注IMPORTANT NOTE:In the event of any discrepancies between the Chinese instruction and the English instruction, the English procedure should prevail.Record Additional Work/Findings(If Applicable) Reference No. Certificate of Release to Service (* Tick as appropriate # Different crews should perform the work on each of the systems)Certifies that the work specified, except as otherwise specified, was carried out in accordance with HKAR-145and in respect to that work, The aircraft / aircraft components are considered ready for Release to Service.
