I was in charge of turbine engine maintenance for CN-235 aircraft and C-130H aircraft in the 15th Special Mission wing of the Republic of Korea Air Force. I have all the experience in line maintenance and depot maintenance of GE-CT7 engines mounted on CN-235. Mainly after warehousing, after engine cleaning and detachment of various covers, internal blade inspection through video scope, we replaced various consumables and exchanged oil. In addition, we maintained/managed blades mounted on turbo prop aircraft. I can obtain an Optional Practical Training (OPT) visa that allows me to legally work in the U.S. for 3 years after graduating from WMU.
