(For specific / detailprodecures,pls refer to AMM).通用步骤/GENERAL PROCEDURESA. 详细目视检查液压部件及其接头有无漏油。Detail visual check the leak trace / evidence of HYD components and their joints / unions.B. 详细目视检查相关区域或者部件是否存在黑色的沉积物或残留物；黑色的沉积物或残留物通常意味 着封圈或密封件老化或者恶化。Detail visual check for wheather there is any black deposits or residuals of hydraulic componentsor within pertinent area, which frequently means that it or them get(s) a o-ring / seals burn-in or deterioration.C. 详细目视检查软管和硬管及其接头有无损伤。Detail visual check that if there are any damage on the HYD component or hose / tube.D. 确认软管和硬管与临近结构间有足够间隙，以及软管与软管之间、硬管与硬管之间间隙足够（间隙标准参考AMM 20-23-14）。Make sure that there is sufficient clearance between the HYD hose / tube and adjacent airframe strutures, hose and hose, tube and tube installations as well. (Refer to AMM 20-23-14 for the clearance limitation)E. 用抹布清洁液压部件、液压管以及临近区域内的挂油和油迹；对有漏油痕迹的部件需根据手册重新打压测试：若仍有渗漏按需调节，更换封圈或更换液压部件。Use the rugs to clean the fluid drops and trace of HYD components, tubes/hoses and its adjacent area.For the leak component, refer to related AMM,pressurize the affected HYDsystem renewdly for leak check, If the leak still exists, do the adjusting work, replacethe O-ring/packing / seal or the component when applicable.F. 在对应的附表里记录漏油情况、损伤或间隙，是否磨损和松动等异常情况以及处理结果；并视情拍照。Recording the leak, damage, clearance, wear condition, loosen state or other abnormalcondition as well as the result if available on the attached table, If necessary, take thephotoes.G. 无论检查结果是否正常，均需将结果反馈给TS系统工程邮箱，以便后续统计。Send the result and the photoes to TS AC,and this is for the convenience of consequentlystatcis collecting and further steps by TSD.H. 如果在航线执行工作时发现异常，根据飞机执行检查时所在基地，将结果反馈给相应航线技术组和维修控制部空客席，以便后续跟踪处理。If find some abnormal, feedback the information to both LN TG and MCD AIUBUS GROUP, depends on which base the aircraft belong to when carry out this EO, and this is for theconvenience of afterwards technical monitoring and make further step as required.如果在定检执行工作时发现异常，根据飞机执行检查时所在基地，将结果反馈给相应技术组，以便后续跟踪处理。If find some abnormal, feedback the information to relevant TG depends on which base the aircraft belong to when carry out this EO, and this is for the convenience of afterwards technical monitoring and make further step as required.注 / NOTES注1 / Note 1:根据维护经验，当发现液压部件或液压管及其管接头有挂油或渗漏的痕迹，需要找到实际漏油的部位 / 漏油点（可能是其上方的部件漏油导致液压油滴在其上）；如果找不到漏油点，可以视情清洁干净，打压测试后，再确定漏油点。Per our experience, when any leak evidence or leak fluid had been found on the HYD compponent and tubes/hoses (including their joints/unions), it is important to find the actual leak point (one of the leak reason can be the leakage of upper components), If you can not find the leak point, it is necessary to clean it, and then pressurize the relevant HYD system to find out the leak point.注2 / Note 2:工作者执行此EO，需要统一将检查结果反馈至TS系统工程邮箱，邮箱地址为：TS。For each aiplane, when executing this EO, you need to feedback the relevant informationto GCAT TSD, and the E-mail for you feedback is TS.对香港航空机队，还需另外反馈至HKA ENGTS工程邮箱，邮箱地址为：For HKA fleet, need to feedback to HKA ENGTS additional, E-mail is 注3 / Note 3：检查结果中如果发现异常，根据所检查飞机所属航空公司的机队情况，分别由以下技术组接收该信息，并对普查发现的问题实施跟踪处理（更换相关部件/封圈或办理FC/DD或临时处理）。Whenever you find something abnormal,according to the aircraft to which airlines it belong,it Is a responsibility of the technical group respectively to receive this information and follow up theinformation to make further step as required,such as,replacement of HYDcomponents/o-rings/packings,or deal with FC/DD,or make other temperory producures.1、香港航空机队：HAKMCC（HKAMCC） For HKA fleet: HKAMCC2、 海南航空和首都航空机队：维修控制部带班组长席（MEDTG_ZZ） For CHH and CBJ fleet: MEDTG_ZZ.注4 / Note 4：检查时参照相关AMM标准或请示以下部门。Ref to AMM standard or ask for instructions from which websites listed below.请示的部门和邮箱 / The department for you asking for instructions & E-mail Adress：1、香港航空机队：HAKMCC（HKAMCC） For HKA fleet: HKAMCC2、海南航空机队和首都航空机队：维修控制部带班组长席（MEDTG_ZZ） For CHH and CBJ fleet: MEDTG_ZZ.注5 / Note 5:由于本EO所涉及的液压部件的构型及图非常多，故并未列出所有构型的图；对于某个液压部件，本EO所列的图仅是示意相关被检查液压部件的位置；实际位置及构型应以IPC或者AMM手册为准。This EO doesnt list every figure for separated configuration of individual affected airplane, because that there are a fat lot of figures in manuals.
