To reduce the aviation maintenance error rate and study the properties and rules of aviation maintenance safety information radiation on the complex network, we study the aviation maintenance safety information radiation in the maintenance personnel based on the theory of complex network. By building a safety information radiation model and defining the radiation rules between nodes through the medium of safety information, dynamic inspect the transformation of the node status in network based on changing the inherent safety degree of the maintenance personnel and the network structure. We analyze the influence of personnel proportion of different inherent safety degree and different network topology structure on the scope and period of safety information radiation when simulate the interactive between nodes on a micro level. With the help of computational simulation, it results that the different inherent safety degrees of the maintenance personnel, as well as the difference of network topology structure, have a lot of impact on safety information radiation. It is beneficial for the safety information radiation to improve the inherent safety degree of the maintenance personnel.
