Supporting off-wing maintenance of an engine of an aircraft

Abstract:

A method of supporting off-wing maintenance of an engine of a specific aircraft includes accessing flight data for a plurality of aircraft including measurements of properties from sensors or avionic systems, and maintenance data that indicates past maintenance or off-wing maintenance of a corresponding engine of each aircraft. A machine learning model is built to predict a life expectancy of the engine of the specific aircraft, measured to future off-wing maintenance of the engine, using a machine learning algorithm, and a set of features produced from selected properties. The machine learning model is built further using a training set produced from the set of features, the flight data including measurements of the selected properties, and the maintenance data. The machine learning model is then output for deployment to predict and thereby produce a prediction of the life expectancy of the engine of the specific aircraft from distinct flight data.
