It will expose the design problem of maintainability of civil airplane to the early stage of design. This paper discusses the composing of the virtual maintenance environment, builds non-immersion virtual maintenance environment of undercarriage, and establishes a part library management system. The characteristic of maintainability models and maintainability analysis based on virtual technique is researched to give the maintainability frame model of civil airplane virtual maintainability analysis. All levels of maintenance time model and maintenance man-hour model are established. Analog-Huffman code is proposed to optimize space partition method in traditional collision detection arithmetic."Maintenance therblig"is brought into the broken down of maintenance tasks, and the new maintenance tasks broken down method is proposed. The demands of human measure, position, and equipment layout in human engineering are discussed, and the verification methods of human measure, position and equipment layout in virtual maintenance are given. Basic principle and verification procedure of maintainability virtual verification is developed primarily, and the reachablity, the visibility, and posture-comfortability are verified.
