1980->

Receiving the “Best New Design” award at Oshkosh 1984 the Buccaneer was a conventional double-surface high-wing, three-axis control ultralight. Powered by a Rotax 277 single-cylinder, it came in three models — open framework, pod, and retractable amphibian. The landing gear was taildragger, or retractable/amphibian, using reinforced fiberglass hull & sponsons. Centre mounted joy stick, rudder pedals, tailwheel steerable through rudder pedals.
Later marketed by Keuthan Aviation as the Buccaneer SX and Buccaneer II, and by Arnet Pereyra Inc as the Aventura 1 HP/A and Aventura II A. A modified version, retrofitable to Buccaneers was marketed by Advanced Aeromarine as the Mallard. The Mallard was available as a conversion for existing Buccaneers or as a complete kit. First flown in 1993.
Although produced as an amphibious flying boat, the Buccaneer can be converted to a land plane by removing the boat hull and floats.

The Aero Adventure Aventura II Sport is a new model designed to minimize the expense and complexity of buying, building, and flying a two seat Aventura. With a strong 65 H.P. Rotax 582, the complete kit started at only $33,400. This is by far the most inexpensive two place amphibian on the market. Invest 250 hours of assembly time and this plane will be flying you and a friend anywhere.
The 100 H.P. 4-Stroke Rotax 912ULS with its 18 gallon fuel tank allows a solid 3 hours of flight with reserve. $44,900 for the complete kit.
The Aventura II XLR has a new engine cowling available, a new graphics package, an amazing new panel with AVMAP’s daylight readable GPS, a VSI, mode-C transponder, and more. Electric gear with indicator lights, differential hydraulic brakes, carpeting, headliner, 600-6 Soft Turf Tires, a 100 H.P. Rotax 912 ULS with an Air Box, a custom stainless steel exhaust, a warp drive 3-blade nickel edge prop and a spinner.

The Arnet Pereyra Buccaneer II first flew in March 1984.
The Arnet Pereyra Aventura UL and HP first flew in March 1995.

Three prototypes, first of which made maiden flight late 1997 or early 1998; most-flown prototype had accumulated 200 hours by March 2001. Public debut late 2002 as HESA 278, having previously been reported as Panha 287.

A fonr-seater; intended for dual military/civil use, though designed primarily to meet military requirements. Designed entirely in Iran, according to manufacturer, although some sources report use of locally made airframe and dynamic components of Bell 206 JelRanger.

Power is by a single turboshaft. Prototypes have evaluated Rolls-Royce 250 and equivalents from Turbomeca and a Russian supplier, but final selection apparently not made by late 2002. Fuel capacity 287 litres.
