The Transavia PL-12 Airtruk is a single-engine agricultural biplane aircraft designed and built by the Transavia Corporation in Australia. The Airtruk is of all metal construction with the cockpit mounted above a tractor engine and short pod fuselage with rear doors. It has twin tail booms with two unconnected tails. Its first flight was in 22 April 1965, and was certificated on 10 February 1966.

Overview

It was developed from the Bennett Airtruck designed in New Zealand by Luigi Pellarini. It has a 1 tonne capacity hopper and is able to ferry two passengers as a topdresser. It can be used as a cargo, ambulance or aerial survey aircraft, and carry one passenger in the top deck and four in the lower deck.

The Airtruk is also sometimes known as the Airtruck. Because the name "Airtruck" was registered by the New Zealand companies Bennett Aviation Ltd and Waitomo Aircraft Ltd, for their PL-11, Transavia found another name for their PL-12 ("Airtruk").

July 1978 saw the first flight of an improved model, the T-300 Skyfarmer, which was powered by a Textron Lycoming IO-540-engine. This was followed in 1981 by the T-300A with improved aerodynamics.

At least 120 had been built by 1988.

The PL-12 was famously seen in the 1985 movie Mad Max Beyond Thunderdome.

As at 2008, there are at least three examples in museums in New Zealand, with an additional one being restored to airworthy status. The second prototype is preserved in the Powerhouse Museum collection, Sydney, Australia.

There is one airworthy Airtruk in Ecka airfield near Zrenjanin, Serbia.
