Transavia Airtruk light aeroplane

Made by Transavia Corporation Pty Ltd in Seven Hills, New South Wales, 1965.

The Transavia PL-12 Airtruk is one of the most significant aircraft designed and manufactured in New South Wales in terms of numbers produced, with approximately 120 made in various versions. Designed by Luigi Pellarini and first built in 1965, the Airtruk was made for agricultural use and was ideal for crop dusting. There was a need for such an aircraft as after World War II many pilots found employment flying light aircraft for aerial crop dusting and spraying or making air drops of fodder in ...

Summary

88/288
This aircraft is a single engine type with an unusual wing configuration, twin tail booms and high cabin. The primary structural elements comprise the hopper, the main undercarriage cross-beam and engine mount. The upper mainplanes are bolted to lugs on the hopper shoulders, and flight loads were transmitted through V-struts to the undercarriage crossbeam which is faired to form the short lower wing. By having the hopper integrated into the main structure enabled the aircraft to withstand greater impact forces in case of an accident.

The aircraft has two separate tail units attached by their supporting booms to the centreline of each wing. Horizontal and vertical tail surfaces remained clean of the slip-stream. The wide gap of 3.5 metres (11 foot 6 inches) between the tail units enabled a loading truck to move in and out from the aircraft on full lock.

The hopper is made of aircraft quality steel and aluminium alloy. The rest of the structure is primarily aircraft quality steel. The wings, booms and tail units are aluminium alloy. Cowls and fairings are moulded resin-bonded fibreglass. The hopper is coated inside with epoxy resin to protect it from corrosive chemicals and to seal it for carrying liquids.

Production

Designed by Luigi Pellarini, the PL-12 Airtruk was conceived as a rugged utility aircraft with the primary function of agricultural spraying and crop dusting. Airtruks were mass produced by Transavia Corporation Pty Ltd, a subsidiary of construction company Transfield Pty Ltd at its plant at in the Sydney suburb of Seven Hills, New South Wales.

The design progenitors of the Airtruk were the Kingsford Smith Aviation Services Pty Ltd PL-7 Tanker, first flown on 21 September 1956, and the Bennett PL-11 Airtrucks, two of which were built at Waitomo in New Zealand based on the Tanker and using war surplus North American Harvard parts. The PL-7 and PL-11 aircraft were also designed by Luigi Pellarini.

In the early 1960s Luigi Pellarini approached Transfield Pty Ltd to assist him to bring to production the PL-12 aircraft he had designed. Despite the fact that Transfield was a steel fabrication and construction company, one of its Directors, Mr Franco Belgiorno-Nettis, was interested in aviation, having wanted to join the Italian Air Force as a young man but considered too short to fulfil the recruiting requirements. In 1964 Transfield had moved into aviation with the importation of a Siai-Marchetti FN-333 Riviera amphibious aircraft, for which it hoped to become the Australian distributor. However, no sales of the Riviera were made. It is unclear if Transavia was formed as a response to Pellarini's approach (with the Riviera sales seen as a side activity) or if the Riviera sales were to be the mainstay of Transavia activities, with the Pellarini proposal accepted because of the lack of Riviera orders.

The aircraft received an Australian Design Award and Prince Philip Prize Certificate of Merit in 1970
