Boeing-Stearman Model 75

The Stearman (Boeing) Model 75 is an American biplane formerly used as a military trainer, of which at least 10,626 were built in the United States during the 1930s and 1940s. Stearman Aircraft became a subsidiary of Boeing in 1934. Widely known as the Stearman, Boeing Stearman or Kaydet, it served as a primary trainer for the US Army Air Forces, the US Navy as the NS and N2S, and the Royal Canadian Air Force as the Kaydet throughout World War II. After the war thousands of surplus aircraft were sold on the civilian market and became popular as crop dusters, sports planes, and for aerobatics and wing walking. Stearman engineers refined the Model 73 into the Model X75 in the summer of 1934, and in July 1935 the Army Air Corps ordered 26 as the PT-13A with Lycoming engines. A civil type certificate was issued on 6 June 1941.
