de Havilland Australia DHA-3 Drover

Design work on the DHA-3 began in 1943 after DHA identified a need to replace the de Havilland Dragon biplane then in widespread use in Australia. Although the British parent company's Dove was being produced at the same time, DHA saw that the Dove was not entirely suitable for Australian conditions. Using the Dove as a starting point, DHA designed an aircraft with three four-cylinder Gipsy Major engines instead of the Dove's two Gipsy Queen six-cylinder engines and a fixed tailwheel undercarriage instead of the Dove's retractable tricycle undercarriage. Like the Dove the DHA-3 was sized to carry 8 to 9 passengers with a single pilot.

The result was an aircraft with the same wingspan as the Dove and a slightly shorter fuselage. The name 'Drover' was selected by Sir Geoffrey de Havilland after suggestions for a name were invited from DHA employees. Thomas King from the Drawing Office came up with the winning name. The first DHA-3 Mk. 1 Drover took to the air at Bankstown Airport on 23 January 1945 piloted by Brian (Black Jack) Walker, DHA's chief test pilot. The aircraft was subsequently flown by Walker to Melbourne for trials by the Australian Department of Civil Aviation, a flight of 460 miles, achieving 140 mph and a fuel consumption of approximately 22 gallons per-hour. During trials a single-engine rate-of-climb of 240 feet per-minute at sea level was obtained. The second aircraft flew during December 1945. One improvement to recent aircraft to improve lift has seen the wing modified with double slotted flaps in place of plain flaps as the DHA-3 Mk. 2.

24 were built for RAAF in the utility transport role and 40 so far for civilian operators including Qantas, Trans Australia Airlines and the Royal Flying Doctor Service.

Commonwealth Aircraft Corporation CAC-21 Wallaby

Around 1947 the Commonwealth Aircraft Corporation began a design study for a regional airliner to replace older aircraft acquired by the airlines during the 1930s. The Wallaby is offered in a 17-15 seat airline version and a 6-7 seat Executive version. The design ethos was on reliability and rugged operation from small airstrips and the unit price of the Wallaby is £65,000. The first of two prototypes was first flown in September 1949 after a 1948 launch order for 20 from Trans Australian Airlines, Papua New Guinea Airlines then followed with a modest order for 6 aircraft. Following certification in August 1950, deliveries began.
