Aircraft are considered to be today one of the most impressive engineering marvels of mankind ever made. While servicing commercial and/or private air transport, milestones of state-of art-technology are being achieved one after another, regularly, on all aspects of their engineering ranging from design, manufacturing, production, till air operations, maintenance and technical training. On these engineering aspects, digitization plays a key role since nowadays, its absence would make rather impossible the safe flight of these marvels on air. This study demonstrates the impact of digitization on these aspects and the interaction of Artificial intelligence (AI) on digitized aircraft systems, aiming to the ultimate goal of systems’ operations being humanly governed, yet human error-free, under the Human Factors (HF) principles and methodology.

Abstract
Context—The maintenance of aero engines is intricate, time-consuming, costly and has significant functional and safety implications. Engine blades and vanes are the most rejected parts during engine maintenance. Consequently, there is an ongoing need for more effective and efficient inspection processes.

Context—The maintenance of aero engines is intricate, time-consuming, costly and has significant functional and safety implications. Engine blades and vanes are the most rejected parts during engine maintenance. Consequently, there is an ongoing need for more effective and efficient inspection processes. Purpose—This paper defines engine blade defects, assigns root-causes, shows causal links and cascade effects and provides a taxonomy system. Approach—Defect types were identified from the literature and maintenance manuals, categorisations were devised and an ontology was created. Results—Defect was categorised into Surface Damage, Wear, Material Separation and Material Deformation. A second categorisation identified potential causes of Impact, Environmental causes, Operational causes, Poor maintenance, Poor manufacturing and Fatigue. These two categorisations were integrated with an ontology. Originality—The work provides a single comprehensive illustrated list of engine blade defects, and a standardised defect terminology, which currently does not exist in the aviation industry. It proposes a taxonomy for both engine blade defects and root-causes, and shows that these may be related using an ontology. Full article
