MRO plays an important role in extending the life of an aircraft by increasing the operational efficiency. It includes services such as overhaul, routine check-up, inspection, repair, and modification of aircraft and their components. These services assure the safety and airworthiness of aircraft. MRO services are conducted on engines, airframe, and components and involve careful examination to detect damages or corrosions caused inside the skin of the aircraft, engine valves, and all the parts where an extensive check is required.
