The DA20 featured around 40 individual improvements, having been effectively revamped to take on the competitive general aircraft market in the region. Originally placed into production in Austria, during the early 1990s, a purpose-build factory was established by Diamond in London, Ontario, Canada to produce the DV20, which was subsequently designated as the DA20. In 1993, the Katana was first displayed to the general public at the Paris Air Show. In 1991, the Katana conducted its maiden flight during May 1993, the type received certification. The Katana has also been developed with a philosophy of offering aircraft that weren't equivalent in terms of performance to any major existing product from competing manufacturers, consciously avoiding instances of direct head-to-head competition. In particular, it had a reduced wingspan, was equipped with flaps, and made use of a tricycle landing gear arrangement. The DV20, while owing much of its design and sharing many features of the Dimona, had several major differences as well. It was decided to develop a new two-seat aircraft, later designated as the DV20 Katana, using the earlier and successful Diamond HK36 Dimona as a basis. During the late 1980s, management at the firm continued to rapidly expand its range of products it also underwent several changes in name and ownership, eventually becoming Diamond Aircraft. In 1981, a new company, Hoffmann Flugzeugbau, was formed in Austria with the aim of becoming a major aircraft manufacturer for general aviation purposes. Additionally, it has been further developed into the four-seat Diamond DA40 Diamond Star. It has been a relative success on the market, having sold in excess of 1,000 aircraft by 2008 and multiple improved variants of the DA20 have been developed. The Canadian-produced aircraft are designated as the DA20. During the 1990s, production of the type was commenced at a new facility in Canada in order to meet demand for the type within the North American market. It was introduced to service during 1993. The DV20 shares many features from the earlier Diamond HK36 Super Dimona. Developed and manufactured by Diamond Aircraft, it was originally produced in Austria as the DV20. The Diamond DV20/DA20 Katana is an Austrian-designed two-seat general aviation light aircraft. For other uses, see DA20 (disambiguation).
