Reliability Case History of An Airborne Air Turbine Starter

Field failure data collected over a span of 7 years for airborne air turbine starters (ATS), which are used to start jet engines in aircraft, offer an opportunity for analysis and determination of reliability parameters. This paper presents; a) Changes in ATS equipment MTBF by year, b) Breakdown of removal causes by year, and c) Cdf of failure times.
