The need for Air Turbine Starter (ATS) condition monitoring is driven by industry demand for continuous improvement in reliability and reduction in repair and overhaul costs. This paper discusses issues for condition monitoring of Air Turbine Starters (ATS), including the need for condition monitoring, selection of monitoring parameters, current projects, and goals for future designs. The USAF is currently conducting a program to develop a simple, stand-alone device capable of indicating impending failures. This device will likely focus on a combination of temperature monitoring and magnetic chip detection. Future ATS condition monitoring devices should be capable of more comprehensive evaluation of starter parameters.
