Researchers extend the concept of the research work and develop newmethods to extract useful information from the fault history record data. The key enablers for revealing the useful information will be selection of key features and data analysis approaches. The focus of the analysis is design of key features and selection of appropriate data analytics, given the fault record data. The baseline approach adapted in this study is pattern analysis of the fault occurrences. The pattern in this study refers to the distribution of aircraft fault frequency across the aircraft fleet for each fault type. The analysis then identifies the candidates of fault types exhibiting abnormal patterns in the *** this end, the pattern is first modeled as a probability mass function (PMF), and the similarity between PMFs is measured using the probability-based distance such as the Bhattacharyya distance. The pattern analysis results can provide information on whether there is a potential problem in the maintenance phase of the aircraft or whether a specific fault type is a fault associated with a specific aircraft only.
