Avia Av-36 Bojar

04/30/2014. Remarks by Walter van Tilborg and Johan Visschedijk: "The Av-36 was one of several light aircraft designs to appear in Czechoslovakia shortly after WW II. The side-by-side two-seater was designed under the leadership of Ing. František Novotný. Featuring a cantilever wing and a 65 hp Walter Mikron 4-III piston engine, the Av-36 prototype made the first flight on July 16, 1946. It appeared at the November 1946 Salon Aéronautique at Le Bourget, Paris France, carrying the registration OK-AHZ.

Reportedly the same aircraft was subsequently fitted with the more powerful 105 hp Toma 4 engine, while the fuselage was lengthened to 26 ft 2.2 in (7.98 m). Redesignated Av-236 the modified aircraft had a generally better performance, including a maximum speed of 136 mph (219 kmh) and ceiling was 13,123 ft (4,000 m). The Av-236 was reportedly first flown in 1947 and retained the OK-AHZ registration, however, nofurther development took place."
