Operational Use
The Soviet aerobatic team first used the aircraft in 1984 when they won the World Aerobatic Championship. That same year the Soviet woman's aerobatic team took first place flying the Yak-55, Kh. Makagonova winning individual gold.
The aircraft has been relatively free of Service Bulletins and Airworthiness Directives and has proved exceedingly effective in competition at all levels. The obvious capabilities of the aircraft and its success in use, together with the relatively large numbers built (some 250) have meant that owners make relatively few modifications and that few are needed.
