Security National Aircraft Corporation

Security National Aircraft Corporation (1933) and Security Aircraft Corporation (1937) originated from the Kinner Airplane & Motor Corporation. Winfield Bertram “Bert” Kinner founded the company in 1919 to produce radial engines as well as light general and sports aircraft. He made a name for himself as a knowledgeable aircraft and engine manufacturer.

In 1922, the city of Glendale, CA bought 33 acres adjacent to the Southern Pacific RR tracks and cleared a 1200-foot runway for the Glendale Municipal Airport. Opened in March 1923, this was considered the first paved runway of the western United States. The first hangar built there was for the ‘Kinner Airplane & Motor Corporation.’ The company was most notable for the development of the first five cylinder-radial type airplane motor. This very engine powered many early biplanes of the 1930s as well as the very well-known Ryan PT-22 USAF trainer during the 1940s.
