In order to implement the reasonable analysis of maintainability human factor in aviation equipment, a virtual maintenance operation verification method of aviation equipment is proposed in this paper. This method which is based on the Jack software follows IETM technology thought. It makes equipment maintenance personnel involved in the virtual maintenance operation process and achieves human assessment of the equipment maintenance and maintenance environmental. The research result shows that this method can analyze the human factors and equipment maintainability verification effectively. And it has great significance for improving the maintainability of equipment development and reducing development costs and shortening the development cycle.
