Air Tractor AT-300 / AT-301 / AT-302
Leland Snow moved to Wichita Falls, Texas, and started design work on a new cropduster, derived from the S2B he had designed and built in the fifties. In 1972 he obtained a small business loan, rented a building back in Olney and started to build jigs and tooling for what was to become the Air Tractor AT-300 – a conventional layout crop-duster powered by a Pratt and Whitney R-985-AN1 of 450hp. A 320 US gallon hopper was installed in a fuselage made of tube construction and included a sealed enclosed cockpit. The aircraft had a conventional tail but with fabric covered control surfaces. The vertical portion incorporated a dorsal fin giving the tail a round shape, unlike later aircraft. The cantilever 45 foot span wing is of all metal construction and incorporates large Fowler type trailing edge flaps. The prototype took seven months to build and Snow first flew the aircraft, N44200, in Septertiber 1973. FAA Certification took fifty-nine days and the first production Air Tractor was sold in March 1974. Seven more were delivered that year including the first Air Tractor AT-301, N4327S, the same aircraft but fitted with a P&W R-1340-AN1 of 600 hp and with an operating weight of 7300 lbs. Twenty aircraft were built during 1975 and, at the end of the year, a new hangar was erected to house the expanding company.
In June 1977, N44415, a turbine version of the AT-301, was flown. Known as the AT-302, it was powered by the then new Avco Lycoming LTP101-A1A of 600 hp. Fourteen were built, followed by the AT-302A in 1980 which had a 400 gallon hopper installed. With an operating weight of 7700 lbs, the aircraft had a wider hopper box and was designed for dry fertilisers.
By the end of 1979, some 229 AT-301 had been built. In 1986 the AT-301 design was improved, including redesigning the wing. Before being superseded by the 401 in 1988, 863 AT-301s were built.

Air Tractor AT-250
In July 1982, a smaller aircraft was flown, N3163L, the AT-250 with a 260 gallon hopper. The wingspan had been reduced to 41 ft 6 in and it was powered by the P&W R-985, the 450 hp radial used on the AT-300. Only one was built and it was sold to a US operator in March 1992.

Air-Tech Skylark
The Skylark is high-wing with a forward engine mounted on a cantilever beam fuselage. The forward-swept wing is rectangular with a tapered trapezoidal tip, and is supported by a single strut. Tail surfaces are classic, and tricycle landing gear is used. The engine and propeller are well forward of the cockpit. The forward-swept wing and under-wing cockpit location produce good visibility; pilot weight has minimal effect on the aircraft’s center of gravity; and the ideal spanwise lift distribution inhibits stalling of the wingtips, ensures against spinning and signals approaching stall by buffeting of the tail surfaces. Two people can easily disassemble the Skylark. By removing three bolts, the horizontal tail surfaces can be folded up against the fin. Each wing can be detached by removing only four bolts. The Skylark wing profile was designed by NASA using technology specially for use in slow-flying aircraft. Features in¬clude low drag in the range of useful air¬speeds, low stall speed, and mild stall characteristics (which are fully exploited by the forward-swept wing to produce a “spinproof” design). Aluminium sheet, extruded tubes and angles, all of general-aviation proven 2024 alloy are used throughout. Airtech uses modern adhesive bonding technology, along with blind and solid rivets. High-strength PVC foam, stamped aluminum ribs, silky-smooth Teflon bellcrank bearings, aluminum pushrods with spherical couplings, “Ceconite 7600 Process” aircraft fabric, precision molded fiberglass fairings, molded plexiglas windscreen all combine to satisfy the most demanding aviators. The standard airspeed indicator, altimeter, tachometer and toe-operated disk brakes are as comforting to the pilot as the contoured seat designed for those up to 6 feet, 6 inches, with “stick-and-rudder” controls. The Skylark uses the Konig SD-570 four-cylinder radial. Using a 2.8:1 reduction drive, the Skylark’s engine turns its 72-inch propeller at only 1500 rpm during takeoff; the result is exceptional static thrust and the virtual elimination of propeller noise.
