The Ryan S-C (Sports-Coupe) was an American three-seat cabin monoplane designed and built by Ryan; one was impressed into service with the United States Army Air Forces as the L-10.

Development

The Ryan S-C was a low-wing cantilever monoplane with a fixed tailwheel landing gear, designed to be an up-market version of the Ryan S-T trainer. The prototype first flew in 1937, and had a nose-mounted 150 hp (112 kW) Menasco inline piston engine. Production aircraft were fitted with a 145 hp (108 kW) Warner Super Scarab radial engine. With the company's involvement in producing trainer aircraft for the United States military, the S-C was not seriously marketed, and only 12 production aircraft were built. One example was impressed into service with the United States Army Air Forces, and was designated the L-10. At the start of the 21st Century, four examples were still airworthy in the United States.
