Driving double training and sport aircraft with tandem seats appeared in the beginning of XX century and for many years has become a standard. However, the practice of flight training showed, what, if the trainee and instructor seated next side by side, can significantly shorten the learning curve. AT 1965 g. on the initiative of young designers OKB was formed a team light aircraft. After aerobatic Yak-18PM was made, brigade 1966 g. has developed a draft of a new multi-purpose four Yak-18T.

As a prototype, it was decided to use the well-proven Yak-18PM. Main aggregates for him was supposed to take the Yak-18PM, Only by building a new fuselage and placing the fuel tanks in the wing panels. The result was made a brand new all-metal semi-monocoque fuselage with a four-seater cabin and a car-type doors. The center section of the wing with the fuselage is formed integrally, placed underneath a large landing flap. wing structure remains the same, How to Yak-18PM. The cabin paired wheel control was installed and a new flight and navigation equipment. Initially, the aircraft was installed engine M-14P power in 300 hp, and then in the process of serial production was replaced by the M-14P power in 360 HP.
AT 1967 g. OKB AS. Yakovlev, the first to show their planes at Le Bourget. The Yak-18T was in the "guest" list, along with the Yak-18PM and Yak-40. Aircraft, did not make a single flight, assembly is completed only the day before departure to France. aircraft painting had to do at night. By morning, the snow-white Yak-18T without any identification mark loaded into the AN-22 and sent to the Salon.
In August naletnoy OKB plant began production tests, who conducted the test pilot Yu.V. Petrov. Exactly one month trial went on a concrete lane LII, and then ground strip airfield Tushino. after performing 73 Flight aircraft was transferred to the state tests. According to the results of tests for the aircraft presented a number of claims. This was especially true over the effectiveness of the control aileron and elevator, and inappropriate form of windshield. Excessive control efficiency was immediately obvious, because these units were removed from a flight of the aircraft. Ailerons "clipped", and horizontal tail feathers replaced by Yak-18A. Round windshield replaced by a rectangular. After completions in June 1971 g. plane again presented on retests. Upon successful completion of the test aircraft launched a series at the Smolensk aircraft plant. The plane continued to experience in the south of the country at a temperature higher than 40 °, and the north. There is the advantage of large windows turned into a serious disadvantage, until the pilots took their places, all the warm air time to go outside.
In the early 1990s,. organized by the Federation of aviation enthusiasts (FLA), I headed by a test pilot and cosmonaut and. Wolf. FROM 28 July 15 September 1990 g. six Yak-18T and one An-2 made a transcontinental flight on the route Moscow - Seattle - Moscow. It was completed about 32 000 km. The next exam served as the flight to Australia. AT 1991 g. seven Yak-18T and one An-2 Difficult months covered the distance in 47 000 km, visiting many countries in Asia. 250 hours in air, 107 landings, 400-490 km per day - all have suffered planes and crews. And yet not a single flight accident. AT 1976 g. specialized medical Yak-18TS was created. It removed the right control post and placed there a stretcher, which were placed in the cabin baggage through the hatch on the guide. AT 1992 g. at the Smolensk aircraft plant resumed full-scale production of Yak-18T.
