Fokker S11 'Instructor' (Div. registraties)

Immediately after the liberation of the Netherlands in 1945, Fokker developed a two/three-seat trainer, the S-11 “Instructor”, which showed a deliberate choice in favour of a side-by-side positioning of the instructor and the trainee. Fokker foresaw much demand for this aircraft, especially as a successor to the highly obsolete Tiger Moth biplane. The maiden flight took place on December 18th 1947. With replacement of the Tiger Moth in mind, the LSK had taken an interest right from the beginning and it ordered 39 examples. In  1950 the first LSK aircraft entered service with the KLu and were placed with the Elementary Flying Training (EVO) at Woensdrecht Air Base. From 1968 the EVO operated from Gilze-Rijen Air Base, as Woensdrecht became a “sleeping” base. The S-11 was built under licence in Italy, Israel and Brazil in large numbers. In addition, Fokker developed a version with a nosewheel, the S-12, but the air force showed no interest. September 1973 brought a definitive end to S-11 service with the KLu, which also meant a farewell to the last propeller-driven aircraft!

The SKHV does not use the S-11 for instruction purposes. As certain components are not obtainable, or only with great difficulty, and as the crooked main undercarriage legs are very vulnerable, only experienced pilots fly this type for a limited number of hours. These planes can, of course, regularly be seen displaying formation-flying at airshows.
