Koolhoven F.K.46

Koolhoven F.K.46

The Koolhoven F.K.46 was a 1930s Dutch training biplane designed and built by Koolhoven.

The F.K.46 was a two-seat biplane with fixed tailwheel landing gear and tandem open cockpits. The prototype first flew in 1933 powered by a Cirrus Hermes engine. A second prototype was fitted with a sliding cockpit canopy. The aircraft entered limited production and four were used by the Nationale Luchtvaart School (Dutch National Flying School). One aircraft was evaluated by the Dutch Army. In 1935 a reduced weight version designated F.K.46L was built powered by a 95hp (71kW) Walter Minor engine but only one was built.

Most of the F.K.46s did not survive the German-invasion in May 1940, although one was sent to South Africa for an evaluation by the South African Air Force although it was expensive compared with the de Havilland Tiger Moth. The surviving aircraft was later impressed into service with the South African Air Force.
