The Koolhoven F.K.56 was a 1930s Dutch basic training monoplane designed and built by Koolhoven.[1]
The F.K.56 was a low-wing monoplane powered by a 450 hp (336 kW) Wright Whirlwind R-975-E3 radial piston engine.[1] Designed as a basic trainer, the F.K.56 had two seats in tandem for the instructor and pupil under a fully enclosed canopy.[1] The first prototype flew on 30 June 1938 and had fixed conventional landing gear and an inverted gull wing.[1] The second prototype had retractable landing gear while a third prototype was fitted with a straight wing and dual controls.[1]
Ten aircraft were ordered by the Netherlands Army based on the design of the third prototype.[1] These ten, including the re-worked first and third prototypes, were all delivered before the German invasion of the Netherlands in May 1940.[1]
Earlier in February 1940 the Belgians had ordered twenty F.K.56 basic trainers and seven had been delivered before the rest were destroyed in an air raid on the Waalhaven factory.[1]
