Fairchild Super 71
The Fairchild 71 was a Canadian parasol-mounted high-wing monoplane cargo aircraft built by Fairchild Aircraft Ltd. (Canada). The Super 71 was an entirely new design that was the first "purpose-built" civilian bush plane for use in remote and northern locales in Canada.〔Molson and Taylor 1982, p. 316.〕
==Design and development==
In 1933, the Fairchild Aircraft Company undertook a study of new designs based on their Model 71. A decision to mount a parasol wing above the fuselage coupled with a rear cockpit position, clearly distinguished this model from the rest of the Fairchild 71 series, although the company designation maintained the family lineage.〔 The choice of the unusual cockpit was predicated on the need to have a large front cargo compartment as well as considering the load distribution in normal operation. In use, pilots found that forward vision was compromised to such an extent that few operators favoured the installation and when the Royal Canadian Air Force ordered the type, the specifications included a new cockpit position directly behind the engine.〔(RCAF.com: The Aircraft: Fairchild Super 71 )〕
The design featured a first-of-its-kind (for Canada) duralumin monocoque fuselage with a streamlined oval shape and strut-braced metal wing and tail surfaces. Wind-tunnel testing not only was used to model the fuselage shape but influenced the placement of the tailplane which was altered from its original T-tail position to a high-mounted tailplane intended to keep the tailplane out of the water spray on takeoff.〔 Engine choices varied with as many as six different powerplants being offered: the Armstrong Siddeley Jaguar, Pratt & Whitney T1D1 Wasp, Pratt & Whitney S1D1 Wasp, Pratt & Whitney SD-1 Hornet, Wright SR-1820-F-41 Cyclone and Wright SR-1820-F-42 Cyclone.〔Molson and Taylor 1982, p. 317.〕
