The paper studies on aircraft field level mean repair time calculation model. Taking the outfield real statistics analysis of a certain type of aircraft for example, calculates the mean time to repair plane, provides reference for calculation and analysis of maintainability quantitative index.%研究飞机外场级平均修复时间计算模型,以某型机当前外场故障数据实际统计情况的分析为例,计算出飞机平均修复时间,为维修性定量指标的计算分析提供了借鉴.
