Method And System For Determining A Faulty Component Of An Aircraft

Abstract: The invention relates to a digital system that makes it possible to determine at least one faulty component of an aircraft. The system comprises: - a first module (MDS1) for determining at least a first symptom (S1i) of the aircraft on the basis of state data (DEk) collected in the vicinity of the aircraft; - a second module (MDS2) for determining at least a second symptom (S2i) of the aircraft on the basis of degradation data (DCk) representative of an abnormal variation in flight data; - a module (MDPD) for determining probabilities of failure in a plurality of components of the aircraft on the basis of the at least first and second symptoms, this module comprising a Bayesian network (BR) trained using a knowledge base (BC) comprising data produced by a natural language processing module (MNLP) configured to process aircraft maintenance reports; - a module (MSAC) configured to flag at least one faulty component from among the plurality of components according to the probabilities.
