一，发动机漏油处理方法A，燃油渗漏1) 如果从主余油口渗漏的燃油总量未超过门槛标准，可以不必做任何工作，发动机可以继续工作。

2) 如果从余油口渗漏的燃油总量超过门槛标准但未超过可用标准，则在25个飞行起落内必须排除故障。

3) 如果漏油总量超过可用标准，则必须立即排故4）如果发现渗漏迹象，完成以下步骤确定渗漏部件和渗漏率。

快速处理：1、对于航前的发动机漏油，往往是天气寒冷导致封圈性能下降导致，可原地暖车5 分钟以后如渗漏不超标可直接放行。

2、航后检查发动机漏油时应该在落地停车后马上检查，如有渗漏，直接打开包皮隔离，如没有渗漏需要试车隔离时必须安排在发动机冷车状态下进行（落地停车3－4 小时后）；3、对于试车不漏的，可采取适当的手段进行隔离，如堵住余油管、拆下余油管接头在内壁喷显影剂等方法；4、对于－5B 的发动机漏燃油，如无法隔离漏油部件，按HPTCCV 软时限控制原则优先更换HPTCCV（目前确定软时限为9000 小时，即如查不到漏部件，且查HPTCCV 装机时间超过9000 小时则直接更换HPTCCV）。

其他型号发动机可参考此原则灵活处理；二，起落架区域漏油处理方法1，减振支柱充气及充油活门不允许渗漏，充气活门（漏气）可通过抹肥皂水来检查。

2，镜面上有黑色油泥是使用过程中的正常现象，如无红油漏出，镜面高度正常，充气、充油活门无渗漏，则正常放行飞机，无须做渗漏检查。

3, 刹车毂由于液压油渗漏堆积在刹车毂里将会影响到刹车的制动性能以及刹车的稳定性，而且刹车毂刹车时产生的高温容易导致起火，因此刹车毂漏油不应按通常的动静封严的渗漏标准来检查，波音已修改手册，在AMM32-41-41/FIG601增加了刹车毂漏油检查的内容刹车毂漏油在航后须更换，过站可按以下标准检查（基地过站有条件时建议更换）：1）液压B系统增压；2）检查刹车毂上的刹车管接头，滑塞，及各个放气口、放油口堵头有无渗漏；3）不踩刹车总渗漏量大于1滴/分钟必须修复渗漏或更换刹车毂；4）踩刹车（或设置停留刹车）总渗漏量大于5滴/分钟必须修复渗漏或更换刹车毂。
