Abstract

Safety promotion is a component of any safety management system (SMS). Safety promotion in Part 145 repair stations can prevent accidents, injuries, and other adverse outcomes by proactively addressing safety concerns and continuously improving safety performance. Along with the safety promotion SMS component, there are three more components, namely safety policy, safety risk management, and safety assurance. Further, safety promotion in Part 145 repair stations can benefit from the relationship with other Part 145 repair stations based on a social network approach. This study reveals that SMS components (namely safety policy, safety risk management, and safety assurance) and the relative position of a Part 145 repair station in the social network can predict safety promotion performance. The data indicates that four predictors (i.e., all SMS components and one social network metric) are significant in this model, and the resulting regression equation predicts 78.6Â % of the variance. Part 145 repair stations and aviation agencies can benefit from the findings by implementing or recommending safety promotion policies considering these predictors.
