Maintenance in the aviation industry has evolved considerably since commercial and general aviation became a modern mode of transportation. ICAO has made maintenance a top priority by directing local National Aviation Authorities, NAA, to have implemented, robust and standardized training and qualifications for all maintenance personnel that work on any safety critical structure or component. There are rules, law and standards that are audited and the aviation industry is, perhaps, the most successful industry in maintaining standards and reliability. With the advent of Unmanned Aerial Vehicles, UAV, the role of maintenance is now needing to be reviewed to determine how and what is needed. This research paper reviews the concepts and importance of maintenance in this new and expanding industry and the complexity of having international standards for engineers to support continuous airworthiness
