This paper describes a program to develop a condition-based maintenance system for the US Navy's LM2500 main propulsion engine. The effort began with research and evaluation of the engine failure modes and effects. Using a well-defined reliability-centred maintenance methodology, the most appropriate maintenance approach for each subsystem and failure mode was identified. Expert rules were developed for the equipment and failures that will benefit from a condition-based maintenance approach. The expert system is based on the US Navy's Integrated Condition Assessment System (ICAS). The proposed system applies new and innovative expert system logic and instrumentation using an upgraded capable ICAS to identify degradation in the marine gas turbine engine and its subsystems.
