Traditional ratio like expected backorder （EBO） ascertaining the inventory strategy of spare parts in practical applications, only eyes on the spare parts inventory system itself, and ignores, the effect of the system information on aircraft or other spaxe parts. In this paper, we introduce the ratio of Aircraft perfect rate, it is a synthesis index to reflect the whole aircraft status, and can deal with spare parts inventory system, concerning not only EBO of spare parts, but also the influence of it on aircraft and other spare parts possibly. We provide the process of calculation that demonstrate how to buy spare parts in case of the maintenance power of aircraft, and have got a clear inventory strategy of spare parts, its easy implementation is illustrated in a case study.
