Hopfner HV.12/34
Crude translation of an excerpt:
The Treaty of Saint-Germain, which regulated, inter alia, the 1920 territorial division of the former Austria-Hungary, forbad strictly aircraft from Austria. Only at the end of 1924 the ban was relaxed, allowing small aircraft and small motorized flying machines to be built to a limited extent again. One of the first who began again with the aircraft, was the engineer Theodor Hopfner, a former military pilot, designed and built in 1925 with two people at the Vienna-Aspern airfield in a shed a light passenger aircraft. With the machine HV2/24,which was designated the official registration A-19, he offered from Aspern scenic flights over Vienna. End of 1934 mandated Anton von Habsburg, Prince of Lorraine, Theodor Hopfner to develop him a light twin-engine passenger aircraft for 5 passengers.
The first flight took place in August 1935 in Aspern, and the aircraft was registered as A-150. The flight characteristics were rated as good and met the expectations. In 1936, the registration was changed to OE-DEA. Based in Aspern, the
HV.12/34 flew irregularly as a private travel airplane, but also as a light transport aircraft. After the annexation of Austria by Germany in 1938 the machine was still there and received the new German registration D-OEEA. Later it came part of the aircraft division of Hirtenberger Cartridge Factory AG in Hirtenberg. When war broke out it was planned be used as liaison aircraft for the Luftwaffe, but since there were problems with the supply of spare parts to the British engines (de Havilland Gypsy) and a conversion to German engines appeared to be takinging too much effort, the HV.12/34 was taken out of use. The further fate is unknown.
