S-1

About the S-1

The Callair S-1 is an American fixed-wing aircraft featuring a high-wing configuration and a tandem seating layout for two occupants. Built primarily for utility tasks such as bush flying, it suits local ranchers and remote operators requiring a rugged machine. The layout consists of a single engine mounted at the front driving a traditional tractor propeller.

The historical lineage of this aircraft traces back to a design originally produced in the early 1940s, which famously encountered enemy action during the attack on Pearl Harbor. Following the Second World War, the manufacturing rights and tooling were acquired by the Call Aircraft Company, which rebuilt and modified several examples with upgraded engines. Although initially more expensive than some contemporary competitors, the airframe gained renown for its durability, leading to subsequent structural modifications and bush plane conversions by later companies.
