The Kreider-Reisner Division of Fairchild produced this tandem two-seat parasol monoplane in 1931. The F 22 was a parasol winged monoplane, generally being cheaper to build and therefore to buy, even if performance was sacrificed for economy.
The prototype of the new model C-7, X783W, was initially powered by the 80 hp Armstrong Siddeley Genet engine before this was replaced by the inline 75 hp Rover engine, complemented by, a more aerodynamic tail group.
The basic aircraft featured a fabric covered, welded steel tube, truss type fuselage which accommodated a tandem seating arrangement with provision for dual controls. The slender wing featured two spruce spars and truss type ribs and was braced internally with steel tie rods. External bracing was accomplished with sloping Vee streamlined steel struts to the apices of the two steel tube pyramids on the sides of the fuselage, to which were attached the legs of the fixed undercarriage.
The C-7A was the first to improve the power of the F 22 and was fitted with a Cirrus Hi-Drive 4 cylinder inverted inline engine, built under licence from Cirrus Aero Engines at Croydon. It provided 20 hp more than its predecessor without altering the lines of the type, and began production during 1935. Several were exported offshore and the aircraft was further developed as a seaplane. Around 60 examples being manufactured fitted with Edo floats, a metal propeller, hand crank-inertia engine starter and navigation lights.
The G7B was specially developed for the more strenuous requirements of the advanced pilot and was powered by the new 4 cylinder 'Pirate' inverted inline which produced 125 hp for a maximum speed of 125 mph (201 kph), a ceiling of 18,000ft (5486 m) and a range of some 400 miles (644 kms). Price was still reasonable at US$3,400 from the factory. There were a few refinements over the C-7A - these including streamlined ‘sport type’ landing gear, bucket seats fitted for a parachute pack and the instrument panels were mounted on rubber. The optional one or two piece wing was now fitted with a leading edge spoiler strip to eliminate float and provided a stall warning as a useful bonus. The wing has I box spars and 14 ribs each, with the same plan shape and profile as the F 24, and a 66 inch chord.
Only one example of the C-7C was built, in 1933, powered by a Wright-Gipsy L-320 engine with a 21 USG fuel tank, for operation in Canada before the C-7D was introduced.
The F22-C7B was powered by a Menasco 125 Super Pirate engine.
Built during the depression the D model was introduced as the cheapest model available. The C-7D was powered by the 4 cylinder Wright-Gipsy 90 hp upright engine. This necessitated a subtle redesign of the cowl, it being higher in front of the cockpit. Maximum speed was 112 mph (180 kp h) and it had a cruising range, using 6 gallons per hour, of 320 miles (515 km). 21 were manufactured, priced at US$ 2,475 from the factory.
The fitting of the 125 hp Warner Scarab radial engine began with the C-7E and his changed the profile considerably with the fuselage contoured to match the frontal profile of the radial. Around a dozen being built.
The engine was replaced with the improved 'Super Scarab' of 145 hp on the C7F. It is thought that only around nine examples were completed.
With pilots requests for engine starters (rather than propping by hand), radios and other comforts,' Fairchild designed the 22C7G to accommodate this and still remain true to the sport plane ethos. This model featured a completely new wing, which not only supported the greater weight of the aircraft, but enhanced manoeuvrability and had the strength to withstand unrestricted acrobatics. Strutted together into several rigid sections the slightly contoured fuselage was very strong, and the whole airframe was capable of + 11G and –9G.
The aircraft had an acceptable but unspectacular performance, attaining a maximum speed of 135 mph (217 km/h), a service ceiling of 16,000 feet (4877 m) and cruising range of 500 miles (804 km).
Production of the F 22 struggled through until the end of the Depression, with the market beginning to improve potential customers turned their attention toward higher performance machines and the comfort of enclosed cockpits. This spelt the end for the F 22, production halting after 127 of all models were built. Fairchild then turned its attention the Fairchild F 24.
