Changgong-91 (meaning Blue Sky) was the first light plane prototype developed by Korean Air and other collaborative companies as a national policy research project led by the Ministry of Science & Technology. Totally 3 prototypes were developed and the first flight was done in 1991. Unfortunately it was not put into mass production due to low marketability forecast by Korean Air. However, Changgong-91 is evaluated as a milestone and a foundation for aircraft development technology in Korea. It is now on static display at the Aviation Pavillion near Jeongseok Airport (RKPD).
