Aircraft Maintenance (MRO, Maintenance, Repair, Overhaul) involves comprehensive maintenance activities such as servicing, repairing, disassembling, and assembling aircraft to ensure continued airworthiness. In South Korea, for a fleet of 40 helicopters, an average maintenance budget of 27.6 billion KRW is spent over 5 years. Particularly in the engine and parts sectors, over 90% of the requirements are dependent on foreign suppliers, highlighting the importance of aircraft MRO support services.
