The '''Ryan S-C''' (Sports-Coupe) (or Sport Cabin<ref name=cassagnere>{{harvnb|Cassagnere|1995|pp=119–144}}</ref>{{pn|reason=a 25 page page-range is almost useless|date=February 2024}}) was an American three-seat cabin monoplane designed and built by the [[Ryan Aeronautical Company]]. At least 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&nbsp;hp (112&nbsp;kW) Menasco inline piston engine. Production aircraft were fitted with a 145&nbsp;hp (108&nbsp;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 11 complete SCs (s/n 202 through 212) were built, all delivered in 1938; two more were later assembled from parts (s/n 213 in 1941 and s/n 214 in 1959). At least one example – probably as many as five, s/n 202, 203, 207, 211 and 212<ref name=cassagnere /> – were impressed into service with the [[Civil Air Patrol]], auxiliary of the United States Army Air Forces for [[anti-submarine warfare|anti-submarine patrol and warfare]] duties on the East coast of the US, and was designated the L-10.<ref>{{harvnb|Donald|1997|p=792}}</ref> At the start of the 21st Century, four examples were still airworthy in the United States.

According to Cassagneres, "The [[spar (aeronautics)|spar]] did not run as one unit throughout the span. The metal '[[monocoque]] spar,' as it was sometimes termed, was developed by Ryan and patented by him. Actually, the spar embodied the full forward third portion of the wing. This leading edge area was assembled as a single unit with major stresses, carried by the outer skin. It was further stiffened by nose ribs and single vertical webs located about one third of the [[chord (aeronautics)|chord]]. Thus the entire forward portion of the wing formed a light but strong tapered box spar. A single perforated [[duralumin|dural]] belly flap of split type, beneath the wing at a point about one-third back from the leading edge, was a new approach to the landing problem."<ref name="ec">{{harvnb|Cassagneres |1982 |pp=170–171}}</ref>

==Variants==
;S-C later S-C-M
:Prototype powered by a 150hp (112kW) [[Menasco C4S]] inline engine, one built later converted to S-C-W.
;S-C-W
:Production aircraft powered by a 145hp (108kW) Warner Super Scarab radial engine, 12 built.
;L-10
:United States Army Air Forces designation for one S-C-W impressed into service in 1942, it was disposed of in November 1944.<ref>{{harvnb|Andrade|1979|p=130}}</ref>
;Later Modifications
:Two SC-Ws exist with a horizontally opposed 6-cylinder [[Continental engine]].  One was modified from a radial-powered SC-W, and one was built with the 6-cylinder engine after WWII using spare airframe parts from the original pre-WWII production run.
