The Buccaneer (also known in some of its many incarnations as the Mallard) is a one- or two-seat ultralight high-wing amphibious flying boat of pusher configuration marketed as a kit aircraft.

The SX remained available on the market until general production ended in 1998, although in 2001 the model was still available as a special order from Aero Adventure Aviation.

The SX was replaced by the improved derivative Aero Adventure Aventura UL and HP single seaters.

[1] The Buccaneer II was a two-seat side-by-side configuration model introduced in 1988 and intended as an ultralight trainer.

Long operational use and the rigours of land and water operation have resulted in weak points in the design being identified as many older aircraft have suffered from bent wing trailing edges, wing root tube brackets, flying wire shackles and tail boom tubes.
