摘　　要：审定维修要求项目(CMR)是为了限制有重大潜在失效可能的系统和相关部件的风险暴露时间,从而强制展开的一种计划维修任务。这类故障存在于多数飞行系统中,只有当潜在失效与其他故障或者事件组合发生的情况下,潜在失效的影响才会凸显出来。以空客A320系列飞机的襟翼收系统为例,开展了功能危害性分析(FHA)确定事件类型,绘制襟翼不能放下故障树,将故障树转化为Bayes网络模型,计算失效暴露时间,确定候选审定维修项目,从候选审定维修要求项目中筛选出审定维修要求项目。The certification maintenance requirements(CMR)are planned maintenance tasks that are mandated to limit the exposure time to risk for systems and related components with a significant potential for failure.Such failures exist in most flight systems,and the effects of potential failures become apparent only when they occur in combination with other failures or events.Taking the flap retracting system of Airbus A320 family aircraft as an example,the first step is to carry out a functional hazard analysis(FHA)to determine the type of event,draw a fault tree that the flap can not be put down,and convert the fault tree into a Bayes network model,and calculate the failure exposure time,determine candidate certification maintenance requirements(CCMR),Finally,CMRare selected from CCMR.
