Thai Airways International Public Company Limited is set to seek board approval for an investment of more than THB13 billion to develop a smart Maintenance, Repair and Overhaul (MRO) hub at U-Tapao International Airport in Ban Chang district, Rayong. The project will be implemented on a 33.6-hectare site leased from the Eastern Economic Corridor (EEC) for 50 years, with construction scheduled between 2027 and 2030.
The MRO facility will be developed as a smart hangar complex and is planned to operate alongside U-Tapao Airport’s second runway, which entered construction in late 2025. Thai Airways will be responsible for the core infrastructure and operations, positioning the hub as a world-class aircraft maintenance centre. The project forms part of the wider aviation city development under the EEC framework.
Under the concession terms, Thai Airways will pay lease fees to the EEC and share revenue with the state starting from the fifth year of operation. Revenue sharing is structured at 3 per cent in years 5–10, 5 per cent in years 10–15, and 7 per cent from year 15 onwards. The airline will also allocate around 30 rai within the site for Bangkok Airways, which plans to invest approximately THB2 billion to develop a narrow-body aircraft maintenance hangar with parking capacity for about two aircraft.
