The Focke-Wulf A 32 Bussard is a German commercial aircraft built by Focke-Wulf-Flugzeugbau AG in Bremen from the early 1930s.

development

The A 32 was developed on the basis of an inquiry made in January 1930 by the manager of Nordbayerische Luftverkehrsflug GmbH , Theodor Croneiß , who urgently needed a commercial aircraft for six to eight passengers due to production bottlenecks at its previous supplier, Bayerische Flugzeugwerke . Focke-Wulf's designer Wilhelm Bansemir based his project planning on the A 28 Habicht , one of which was built and delivered to Norddeutsche Luftverkehr AG in June 1929 . The work was carried out under great time pressure, as the handover had already been agreed for March 1930. Despite initial problems with the cooler , the appointment was kept and the aircraft, equipped with an L-5 engine according to Croneiß's request , was flown in by the works pilot Cornelius Edzard , whereby, according to Henrich Focke , it should have reached a peak altitude of 3800 m. The aircraft then passed the acceptance flights at the German Aviation Research Institute (DVL) in Berlin-Adlershof and was flown from July of that year with the registration number D – 1910 on the Northern Bavarian Air Transport Flight. He was satisfied and ordered another A 32, which was used from August as the D-1942 .

The three remaining aircraft built were delivered to the DVL, the serial number 113 ( D-2129 ) in August 1931 and the serial number 104 ( D-1997 ) in July 1932. Both broke at the same time in June 1934 during testing. Another A 32 with the serial number 105 received the registration D-2079 in May 1931 and was tested more intensively, whereby the DVL one-flyer Joachim von Köppen certified the model as well as its two predecessors A 20 and A 28 spin safety .
