Abstract
An apparatus for maintenance of an aircraft is provided. The apparatus accesses flight data for a flight of the aircraft and predicts and thereby produces a predicted state of the aircraft for a next flight of the aircraft based on the flight data. The apparatus deploys a similarity detection model to determine similarities between the flight data for the flight and a training set of flight data for previous flights of the aircraft. The similarities determined by the similarity detection model are values of independent variables of a classification model. The apparatus deploys the classification model to predict and thereby produce a predicted state of the aircraft for the next flight of the aircraft based on the values of the independent variables, and generates an alert when the predicted state of the aircraft is a fault state.
