We initiatively expand the MRO business
as the greatest airport in Northeast Asia equipped with global infrastructure.
The term MRO is an acronym that stands for maintenance, repair, and overhaul. An MRO is an aircraft facility capable of performing required maintenance, repairs, and overhauls on necessary devices, equipment, machinery, and infrastructure, which is essential to maintain the safety and reliability of aircrafts to promote safe operation while improving aircraft performance.
