History Bücker-Flugzeugbau GmbH
Bücker Bü 131 Jungman
The Bücker Bü 131 Jungmann (freshman, young man) is a German 1930s basic training aircraft which was used by the Luftwaffe during World War II.
After serving in the Kaiserliche Marine in World War I, Carl Bücker moved to Sweden where he became managing director of Svenska Aero AB (Not to be confused with Svenska Aeroplan AB, SAAB). He later returned to Germany with Anders J Andersson, a young designer from SAAB. Bücker Flugzeugbau GmbH was founded in Berlin-Johannisthal, in 1932, with the first aircraft to see production being the Bü 131 Jungmann.
While it was Bücker Flugzeugbau's first production type, the Bü 131A was the last biplane built in Germany. It had two open cockpits in tandem and fixed landing gear. The fuselage was steel tube, covered in fabric and metal, the wings wood and fabric. It first flew on the 80 hp (60 kW) Hirth HM60R..
