André Kieger has been responsible for the design and construction of three low-wing, two-seat light aircraft, including the AK-01 of 1989 (F-PZMO, a tailwheel variant) and AK-2R, produced in 1998. The latter (F-PARJ) has now flown more than 1.200 hours as a tug at the Haguenau gliding club while a second example of the former (F-PAKT, tricycle landing gear) has been used by the Haguenau flying club since 2001.
