Modern aircraft engines must operate at ever-higher temperatures, pressures, and rotational speeds, in order to increase power and improve efficiency. This creates an extreme operating environment for engine blades, which are the most frequently rejected part during engine maintenance. Their failure can lead to severe unairworthiness and fatalities. Hence, it is important to identify and precisely define all defects. This paper provides a comprehensive and illustrated list of engine blade defects, as well as standardized defect terminology, which currently does not exist in the aviation industry. It proposes a taxonomy for both engine blade defects and root causes, and an ontology that shows their correlations. View this paper
