摘　　要：飞机因其结构复杂,组成部件繁多,要检测的参数很多,而且各种参数之间存在着复杂关系,故障现象也多种多样,最常见的也有几万种,这就决定了飞机的故障诊断是一项非常复杂的工作。文章阐述了故障树分析法(Fault tree analysis,FTA),并以B737-300为研究对象,把两者有机的结合起来,并在故障树的建立和定性定量分析的基础上进行空调系统故障诊断,使空调系统能够正常安全运作,尽最大可能保证旅客的安全,为旅客提供一个舒适安逸的生存环境。Because the aircraft structure is complex,various components,a lot of parameters to detect,and there is complex relationship between various parameters and fault phenomenon is varied,the most common also have tens of thousands of species,which determines the fault diagnosis of aircraft is a very complicated work.This pap.er expounds the Fault tree analysis （Fault tree analysis, FTA）,and to a B737-300 as the research object,put the two organic combine,and in the establishment of Fault tree qualitative and quantitative analysis on the basis of air conditioning system Fault diagnosis,the air conditioning system can normal operation of the security, as far as possible to ensure passenger safety, for passengers to provide a comfortable living environment.
