The issue of setting maintenance intervals based on the situation has always been a hot topic in the civil aviation industry. The size of the inspection interval is related to many factors. Environmental factors affect the formulation of inspection intervals by affecting the life distribution of components. <br>From the perspective of system simulation, aiming at the formulation of maintenance intervals based on the situation, a relevant model was constructed based on the analysis of the influence of environmental factors on the formulation of intervals. The method of generating random fault data through programming to establish a simulation model is used to simulate the process of formulating maintenance intervals based on circumstances. At the same time, aiming at the problem that the environment has too slow influence on the degradation process of components, the principle of accelerated life experiment is used to establish the influence model of environmental factors on the life of components. <br>Through model simulation, it is found that under the same level of safety, the greater the difference between the actual environment and the optimal environment, the smaller the inspection interval of the condition-based maintenance, the higher the maintenance cost. This has a certain reference value in the formulation of the theoretical research of the aircraft maintenance plan and the actual formulation of maintenance intervals.
