The Boeing Stearman A75N1 (PT-17) was produced by the Stearman Company in Kansas. The Stearman aircraft are the most famous biplane, open-cockpit and two- seater training aircraft in aviation history. It was produced for the US Air Force and Navy in the early 1930s. The first prototype flew in 1934. When the Stearman Company was taken over by Boeing in 1938, this aircraft became known as the “Boeing Stearman”. One of the most important characteristics of the aircraft serving as a Military Training aircraft is they were produced by women during the World War II.

This steel constructed aircraft has wooden wings and fabric covering and has lower costs compared to metal aircraft. There are 7 cylinder radial Continental W670-6N engines and Sensenich W98AA-64 wooden propellers on the Boeing Stearman A75N1 (PT-17).

In the post-war era, most of the Stearmans were used in many fields such as airshows, aerial photography and the film industry. It was preferred in agricultural lands because it is capable of landing on and taking off from rough places through its strong airframe and large wheels. The Stearman aircraft also attracted a lot of attention with “wing walking “ performances during the airshows.

The 1943 model Boeing Stearman with serial number 75-4620 was brought to the M.S.Ö. Air & Space Museum in March 2015 with the contributions of Ali İsmet ÖZTÜRK.
