摘　　要：反推作为飞机发动机的一部分在降落时起到减速的作用,对缩短着陆滑行距离有着显著的效果,反推故障将对飞机性能和飞行安全造成一定的影响,了解反推系统的原理、构造和分析故障原因就显得非常重要。本文结合空客公司相关技术文件与实际维修经验,总结分析产生“ENG 1 FADEC;CHB HYD CNT UNIT/HC/EEC1”故障的原因,便于航线机务快速找到锁定故障的方法,有效排除故障。As a part of aircraft engine, the thrust reverser system plays the role of slowing down the aircraft when landing, and has a significant effect on shortening the landing taxiing distance. The thrust reverser failure will have a certain impact on the aircraft performance and flight safety. Therefore it is very important to understand the principle and structure of the thrust reverser system and analyze the failure cause. Based on relevant technical documents of Airbus and practical maintenance experience, this paper summarizes and analyzes the cause of "ENG 1 FADEC;CHB HYD CNT UNIT/HC/EEC1" fault, in order for airline maintenance personnel to quickly find the method of locating the fault and effectively eliminate the fault.
