The Aircorp B2-N Bushmaster is a prototype Australian light aircraft designed for aerobatic, touring, and utility use.
[Taylor 1993, p.914] It first flew in 1989 and did not enter production.
Design and development
The Bushmaster is a high-wing, strut-braced monoplane of conventional design with fixed, tailwheel undercarriage.
It has two seats, side-by-side, in an enclosed cabin.
Fuselage construction is of welded steel tube, covered in fabric, and the wing is all metal.
It is powered by a nose-mounted engine driving a tractor propeller.
This engine was originally a
Norton Aerotor 90 wankel engine, also intended to power production examples.
The prototype, ''VH-BOI'', first flew on 28 October 1989.
Certification for the original Norton powerplant was delayed, so it was changed to a
Lycoming O-235

after this first flight.
[Carman 1992, p.11] The engine change necessitated some other modifications to the aircraft, including changes to the engine cowling and the undercarriage.
The Bushmaster received its Certificate of Airworthiness in late 1990.
Production was to take place at
Caboolture Airport.
However, by early 1992, Aircorp was under financial pressure, which led one of the original partners in the company, Peter Ferro, to buy it out to continue the project.
By 1992, a range of models had been proposed, and the prototype was modified to make it comply with American
FAR 23

regulations in preparation for marketing in the US.
Production examples were also to have redesigned wing spars, relocated fuel tanks, wings braced with I-struts instead of the V-struts of the prototype, and three-position flaps.
Flight testing of the four-seat B4-80 model was anticipated to start in late 1992.
However, by 2007, no further examples had been produced and the prototype was sold off.
