The F.K.46 was a two-seat biplane with a fixed tailwheel landing gear and tandem open cockpits.

The prototype first flew in 1933, powered by a Cirrus Hermes engine.

In 1935, a reduced-weight version, designated F.K.46L, was built and it was powered by a 95 hp (71 kW) Walter Minor engine.

However, one was sent to South Africa for evaluation by the South African Air Force even though it was expensive compared to the de Havilland Tiger Moth.

The surviving aircraft was later impressed into service by the South African Air Force.
