Wolf Hoffmann designed the Wolf Hoffmann Flugzeugbau KG H-36
Dimona motor glider at Günzburg, Bayern, Germany. The first of three
prototypes flew from there on October 9, 1980. In 1981 the series
production was undertaken under the new company name Hoffmann
Flugzeugbau GmbH at Friesach, Kärnten, Austria.
In 1985 the company became a subsidiary of Simmering-Graz-Pauker AG,
was renamed Hoffmann Aircraft Ltd., and moved to Vienna,
Austria. New production facilities were established at Wiener
Neustadt, Lower Austria, Austria, in 1987. In 1991 the control of
the company was taken over by the Dries family and again the name
was changed to HOAC AG.
To supply the North American market a full production facility was
established in London, Ontario in 1992. This new company was named
Dimona Aircraft, what was changed to Diamond Aircraft
Industries Inc. in 1996. Diamond established a new Diamond
Flight Center, including training facilities, at the London Airport
In 1998, in order to align with the North American operation, HOAC
in Austria was renamed Diamond Aircraft GmbH. It acquired
the Wiener Neustadt - East Airport and extended the production
facilities at the airport significantly in 1999. The same year
Diamond also opened a factory sales, service and flight training
center in Egelsbach, Hessen, Germany. In 2004 a composites facility
was added to the main company at Wiener Neustadt.
