A75L3

The A75L3 is a foundational biplane trainer, nearly identical to the renowned PT-13 Kaydet. This aircraft was developed from the Stearman Model 70, which served as the prototype for a long series of biplane trainers for the U.S. Army Air Corps. The A75L3 was typically powered by a 225 hp Lycoming engine, with about 43 examples built around 1940-1941. It received its type certificate in 1941, and more than 60 of the A75L3 (A75N1) series were manufactured for civil and export use.

Manufacturing history is rooted in the Stearman Aircraft Division of the Boeing Airplane Company, located in Wichita, Kansas. Boeing, founded in 1916 by William E. Boeing, acquired Stearman Aircraft in 1934, solidifying its position in military and commercial aviation. The Stearman models became Boeing’s standard primary trainers during the crucial World War II era.
