The Yakovlev Yak-54 is a two-seat aerobatic and sports competition monoplane of Russia developed in the 1990s. It was designed and manufactured by the Yakovlev Aircraft Corporation and took its maiden flight on December 24, 1993.
The Yakovlev Yak-54 was a result of the modification of the Yak-55M single-seat aerobatic aircraft. In 1992, the prototype of one of the variants of Yakovlev Yak-55 designated as the Yak-56 was expected to fly, however, due to the delays in the production of the 300-horsepower VOKBM M-16-8 piston engine, Yakovlev opted to produce the Yak-54 instead.
On December 23, 1993, the Yak-54 took to the skies for the first time. The aircraft is a two-seat sport and aerobatic monoplane used for training sports pilot for aerobatic flights as well as for partaking in the sports competitions in the air.
