The Security Airster S-1 is an American two-seat single-engined monoplane designed by Bert Kinner and built by his Security National Aircraft Corporation later named the American Aircraft Corporation.[1]
Development
The Airster S-1 appeared in 1933 after the designer Bert Kinner had started the Security National Aircraft Corporation to build it.[1] The Airster S-1-A was a side-by-side two-seat single-engined low-wing braced monoplane, it had folding wings and a fixed tailwheel landing gear.[1] The aircraft was powered by one of Kinners engines the 100 hp (75 kW) Kinner K-5 radial.[1] A coupe option was available to enclose the open cockpit.[1] The economic situation in the United States of the early 1930s was not a good time to launch a light aircraft and only 15 were built when production of the S-1A stopped in January 1935.[1] One of the purchasers of the aircraft turned out to be Edgar Rice Burroughs, author of the Tarzan series.[2][3]
In 1939 with the company renamed the American Aircraft Corporation, Kinner attempted to restart production with a revised Airster S-1-B, again powered by his own engine a 125 hp (93 kW) Security S5-125 radial.[1] Times were no better and only about five were built before the factory and assets were bought in 1942 by the National Airplane & Motor Company.[1]
