Through analyzing the characters of aviation material and current situation of it, studying the development roadmap of foreign CBM, enlightened by the development peculiarity and pattern of it, the necessity and difficulty points of implement CBM on aviation materiel are indicated. By analyzing the intrinsic nature of CBM, the deficiencies of implementing it in practice are pointed out. The frame of Synthetical Condition-Based Maintenance (SCBM) is presented ground on current situation of aviation materiel. Then we study the essential contents、technique process and maintenance decision model of it. Finally by analyzing the implement flow in one real control system, the efficiency and feasibility of practice SCBM in aviation materiel is illuminated.
