Savoia-Marchetti SM.80

The Savoia-Marchetti SM.80 is a two-seat monoplane amphibian tourer designed in Italy in the early 1930s, with a single tractor engine mounted above the wing; the SM.80bis is a four-seat variant powered by two pusher engines. It was a cantilever high-wing monoplane whose fabric-covered wooden wing was divided into sealed cells to give buoyancy in case of hull flooding, with a flat-sided fuselage whose single-stepped underside was double planked and copper riveted for corrosion resistance. The side-by-side cockpit sat slightly into the wing leading edge, with a baggage space or third seat behind, and fixed floats on the wing gave lateral stability on the water. The first aircraft used a 112 kW Colombo S.63 engine, and one SM.80bis, I-TATI, is now preserved at the Volandia museum.
