A two-seat, twin-engine personnel transport and air ambulance. Manufactured by Turkish company Turk Hava Kurumu Ucak Fabrikasi in the capital city of Ankara, it was developed by three Poles: Stanislaw Rogalski, Jerzy Teisseyre and Leszek Duleba. A low-wing cantilever monoplane of wooden construction, with retractable main undercarriage. The air ambulance version carried two wounded on stretchers, while the transport version (THK-5A, later improved and redesignated THK-10) could carry six passengers. Altogether 13 examples were built, one being sold to Denmark. Following the THK's takeover by MKEK company a further development of the plane was planned, but this never materialised.
