2025年1月，有15*2飞机反应下防撞灯不亮，三个频闪灯不亮。受MEL限制无法放行。
这两路的供电和控制是完全独立的线路，且上/下防撞灯使用相同的供电源。因此有一定概率是两套系统同时失效的可能。
1、经过对防撞灯供电的测量，发现供电组件上游也没有电，量线发现供电线路存在断路。
2、对频闪灯电门，使用线路直连，也不能点亮。
转而看两者的物理上接近的情况，供电上有共同经过D40506P插头的情况。一个是使用B2、一个是A3。
通过的使用D40506P插头的系统验证，发现还有一个系统，前货舱火警A环路故障。
因此，重点检查D40506插头和插座，在E2-2架接近后。发现存在烧蚀的情况。
实际拆下后，发现A3钉烧蚀严重，其他钉并未发现明显的烧蚀。
因此分析烧蚀的源头为下防撞灯供电线路，产生的短路烧蚀。其他两个临近插钉，应该是烧蚀对旁边胶片的挤压影响了连接性，表明触点实际是比较敏感的。
进一步看D40506上下游，上游为跳开关C111,件号BACC18AD5,为5安培；下游为M1745供电组件。
针对该线路，查询FTD和FIX均无相关案例说明。插头机队未有过订料历史。
