History
The F.K.48 first flew on 24 May 1934. The fuselage was of welded steel tube construction covered in fabric, and the wings were wooden structures skinned in plywood.
Variants
Only one F.K.48 was built, registered PH-AJX. It was powered by two 130 hp de Havilland Gipsy Major engines.
Where you'll see it
The sole example quickly gained the nickname Ajax. KLM used it on the Rotterdam-Eindhoven route until 1936, when it was retired to training and instructional duties within the airline.
