was relatively successful, becoming the biggest-selling motor glider in Europe and, by 2004, four separate versions of the Dimona - which were marketed as the HK36 Super Dimona or Xtreme - were available for purchase. In 1985, the company was renamed Hoffman Aircraft Limited and became a subsidiary of Simmering-Graz-Pauker AG, which resulted in the company's headquarters being relocated to Vienna. During 1987, the company reestablished its main production facility in Wiener Neustadt, Lower Austria. During the late 1980s, amid the various corporate changes in both identity and ownership, the company's management had proceeded with its work towards the goal of rapidly expanding Hoffman's product range. In line with this mission statement, it had been decided to develop a new two-seat aircraft, the HK36R, which used the H36 Dimona as a basis. This would result in the production of the DV20 Katana, a Rotax 912-powered two-place light aircraft, which was the company's first production general aviation aircraft. 1990s During 1991, Hoffman's parent company was renamed HOAC AG and was purchased by the Dries Family. In 1992, as a measure to establish a strong foothold with the competitive North American market, Hoffman decided to launch a second manufacturing facility located in London, Ontario, Canada. By this point, the company considered itself to be secure in its dominance of the European market, and sought to be embraced by American operators as well. Prior to 1996, the Canadian branch operated under the name Dimona Aircraft, this was changed to Diamond Aircraft in 1996, while the parent company remained as HOAC at this time. In 1993, the Austrian-built DV20 Katana received certification, clearing the type for its entry to service. According to aerospace publication Flight International, the DV20 "confirmed Diamond as a serious contender for the light aircraft crown". An improved model of the DV20, designated as the DA20, was developed for North America and was manufactured in Canada; the first Canadian-built DA20 was delivered in 1995. It received the Flight magazine's Eagle Award for best light aircraft in the same year. During 1997, the delivery of the 500th DV20 occurred; it was also in this year that the introduction of the DA20-C1 took place, which had improved performance and load capabilities. The DA20-C1 Eclipse (an improved version of the DA20-C1) also entered production. In 1998, the parent company was renamed Diamond Aircraft GmbH to better align with the naming convention of the North
