Abstract:

The maintenance and support model of modern aircraft is evolving from reliability-centered scheduled maintenance to condition-based predictive maintenance. Implementing predictive maintenance is a systematic project that requires integration and application of various applicable technologies, processes, and capabilities, involving management policies, standard specifications, business processes, new technologies, etc. throughout the design, operation, and support stages of the life cycle. This article reviews the research progress of aviation predictive maintenance from the perspectives of key technologies and applications. The research on health monitoring, fault diagnosis, failure prediction, and predictive maintenance decision technology is analyzed. Applications of predictive maintenance in military and civilian aviation are summarized, including government policies, industry standards, industry practices, and user experience. The technical and application challenges currently faced by aviation predictive maintenance are also analyzed, and the areas that need to be focused on in the future are discussed.

Key words: aviation maintenance, predictive maintenance, aircraft health monitoring, aviation equipment support, scheduled maintenance
