Lohner-Etrich AD 354

  On 14 June 1913, Lohner-MLG entered two Lohner-Etrich Renn Gebirgs monoplanes (racer mountain type - works number AD 127 and AD 354, powered by an 85 hp Hiero engine) in the Second International Flugmeeting at Aspern, assigned to pilot Gianni Widmer and both carrying the competition number 26. When the radiator hose on AD 127 ruptured, Widmer, although badly scalded, quickly switched to the second monoplane (AD 354), but he failed to place in the top ten finishers. In early 1914, Etrich “No.58" was purchased by the LA and given the designation Versuchs Gebirgs Etrich E-1 (experimental mountain type). From available photographs, it appears that AD 354 and Etrich E-1 (No.58) are the same aircraft. Etrich E-1 was under repair at Flugpark 3 in Gorz during January-February 1915, but appears to have been written off and consequently not listed in the February 1915 LA directive for re-numbering aircraft.

Lohner 10.15

  The Schichtpreis Eindecker Type 1914 (AD 489) was the last aircraft built by Lohner to incorporate Taube wing-warping controls. Construction was begun in October 1913 and completed on 29 December 1913. On 4 February 1914, Lohner offered the monoplane, powered by a 80 hp Gnome rotary engine, to the LA for testing and would supply new wings if desired, but the LA was not interested.
  AD 489 was one of the two aircraft entered by Lohner pilot Viktor Wittmann in the Schicht Flug but he chose to fly Pfeilflieger AD 553 (10.16). In June 1914, AD 489 was flown by Gianni Widmer (competition No.23) in the Third International Flugmeeting, but he failed to win any prizes. Requisitioned at the start of the war, AD 489 was sold to the LA in October 1914 and designated Gnome-Etrich or Lohner A 23. It became Lohner 10.15 in April 1915. In its long training career, the monoplane served with Fleks 1 and 8 and was still active with Flek 6 as late as November 1917.
