| Summary: | In view of the impact of health and use monitoring system (HUMS) is not fully considered in the traditional MSG-3-based civil helicopter maintenance program analysis, as well as the problems of inadequacy and disadvantages exposed during operation. In this paper the influence of HUMS on the maintenance task of civil helicopter is innovatively studied, and the impact of HUMS on the maintenance tasks of systems/powerplant, structural, zonal and L/HIRF (lightning/high intense radiation field), under the overall analysis framework of MSG-3 are comprehensively analyzed. A set of MSG-3 maintenance task analysis suggestions considering HUMS technology are put forward, which can provide key technical support for the development of a new generation of civil helicopter maintenance program in China.
