N2 - Reasonable line replaceable unit (LRU) division can effectively improve the maintenance efficiency of civil aircraft, avoid the phenomenon of aircraft parking, and ensure the safe and reliable operation of civil aircraft. Under the premise of considering the influence of various factors in the design stage and operation process of civil aircraft, the design and operation of civil aircraft are carried out, a method of LRU division, two-step iterative analytical hierarchy process (TSI-AHP), is proposed. Firstly, the influence of relevant factors in the design and operation stages on LRU division of civil aircraft is investigated. Secondly, the influence of various factors are comprehensive considered, and the lowest structures of product decomposed by their function are regarded as the study objects, and the TSI-AHP is applied to implement LRU division of civil aircraft. Finally, the landing gear system of ARI21-700 aircraft is treated as an example to realize the LRU division using the method proposed. The results show that the LRU partition method based on TSI-AHP can effectively realize the LRU partition of landing gear system of ARI21-700 aircraft. The LRU partition project in this paper is basically consistent with the actual LRU project, which verifies the feasibility and effectiveness of this method, and provides a new idea for the LRU partition of domestic civil aircraft.
