The THK-16 Mehmetçik (Turkish: "Little Mehmet"[1]) was an aircraft designed in Turkey in the early 1950s to provide the Turkish Air Force with a domestically designed and built jet trainer.
[2][3] As designed, the THK-16 was to have been a conventional, mid-wing monoplane with the pilot and instructor seated in tandem under a long canopy.
Power would have been provided by two small turbojets mounted in underwing nacelles, and construction was to have been metal throughout.
[3] Design work was practically complete in 1952 when Türk Hava Kurumu was bought out by MKEK.
Although the THK-16 was selected as one of the THK designs that MKEK felt was worth continuing with and allocated the designation MKEK-3, the Turkish Air Force purchased the Lockheed T-33 Shooting Star as its jet trainer and work on the local design was abandoned.
