Type Werk.Nr Registration History
99 D-1908, D-IJEF Tested at Lipetsk, later  to  the RDL Erprobungsstelle, Staaken .  Used during mid thirties for weather reconnaissance
In 1932, Focke-Wulf Flugzeugbau AG produced the A.40 light multipurpose aircraft . Like many other projects of that time, it also had a second purpose - it could be used as a light reconnaissance aircraft.
The A.40 was a two-seat wooden high-wing aircraft powered by a Siemens Sh.22 engine (Jupiter VI manufactured under license by Siemens) with 510 hp. (375 kW).
The only  the aircraft (Werk. N. 99) successfully passed factory tests, and after receiving the registration number D-1908, it was sent for military testing to the "secret" flight school in Lipetsk.
After returning from the USSR, the aircraft received a new designation and registration number - Fw.40 (D-IJEF). It was transferred to the Berlin research center RDL Erprobungsstelle, where it was used for several years as a weather reconnaissance until it was replaced by the more advanced He.46.
