Recently, a Boeing 737-800 aircraft from Jeju Airlines in South Korea arrived at the scheduled inspection hangar of Hainan Free Trade Port's one-stop aircraft maintenance industry base to receive special maintenance services from Dahua Aircraft Maintenance Service Co., Ltd., a subsidiary of Hainan Airlines Technology. This is the first time that Hainan Free Trade Port has undertaken maintenance services for aircraft entering South Korea. The estimated maintenance period for the aircraft entering South Korea this time is about 16 days, and it can enjoy preferential policies such as free entry maintenance deposit, adding bonded aviation fuel, and tax exemption for maintenance aviation materials at Hainan Free Trade Port.
