Fleet 50

The Fleet 50 Freighter was a twin-engine biplane Canadian general utility aircraft designed and built by Fleet Aircraft. This peculiar-looking aircraft had promise as a freighter and general use aircraft, but it was underpowered and only five were built.

Development

Design was started in 1936 to create a general purpose twin-engined utility aircraft for the Canadian market. It was designed as a short take-off freighter with features added to ease cargo handling. The Freighter was a biplane with the lower wing an inverted gull wing with either a float or wheel landing gear. Two radial piston engines were mounted in nacelles on the upper wing panels.

The fuselage structure was welded steel tubing with duralumin formers, and a semi-monocoque duralumin nose section. The wings were stressed-skin metal structure on the inboard panels and fabric-covered wood beams and duralumin ribs on the outboard panels. The fuselage had room for two crew and up to ten passengers. Large doors and a roof-mounted chain hoist were fitted for use in the cargo role.

The prototype designated the 50J first flew on 22 February 1938, powered by two 285 hp (213 kW) Jacobs L-5MB 7-cylinder radial engines. It was later re-engined with 330 hp Jacobs L-6MB engines and re-designated the 50K. A further four aircraft were built, all with L-6MB engines.

None of the aircraft was operated for long, as the design was underpowered and could not maintain altitude on only one engine.
