A high-winged, single-engined monoplane used by Aeroflot as a utility aircraft and air ambulance. NATO code name ‘Creek’.
The Yak-12 was a single 179kW AI-14R-engined high-wing light general-purpose aircraft built in several versions from the late 1940s. It was known to NATO as Creek.
The Yak-12A four-seater presented a complete re-design of the basic aircraft, providing greater payload and range. Apart from additional windows, the fuselage remained unchanged, but entirely new wings of reduced area with taper on the trailing edges of the outboard panels was introduced. Single bracing struts replaced the earlier Vee-type struts, along with re-designed tail surfaces. Fuel capacity was substantially increased. Appearing in 1957, Yak-12A manufacturing was sold to Poland, the first Polish production model flying in August 1959 and production continuing until 1961.
In 1952 the Yak-12R (Creek-B) appeared. This retained the mixed construction of the original but introduced the 240 hp Ivchenko AI-14R radial.
The Yak-12R was superseded in production by the Yak-12M (Creek-C) which employed an all metal structure with fabric covering. In 1955 a manufacturing licence for the Yak-12M was acquired by Poland, the type entering production at Okecie in 1955
The Shanghai Dragon Volant – 1 version was built in Shanghai, China.
The Chinese Chan Yang 1 version of the Yak-12 featured a 220 hp engine.
