Ergonomics Model of Aviation Maintenance Human Error Analysis and Control

Most aviation accidents were due to human error. This paper focuses on the statistical analysis of aviation maintenance human error data, combining ergonomics and civil aviation maintenance theory to build the maintenance human error influence and prevention model, and on the maintenance human error causes from the man-machine-environment aspect, especially focusing on the three interfaces of man-man, man-machine (aircraft), and man-environment. Then, the human error prevention model was established based on the SHEL ergonomics theory from L-L, L-H, L-S, L-E, as well as the organization and management system aspect. Meanwhile, human error prevention recommendations were given. The conclusions provide a reference for the maintenance human error analysis and management.
