Fokker S.14 Machtrainer
After World War 2 the N.I.V. (Nederlands Instituut voor Vliegtuigontwikkeling (Dutch Institute for aircraft development) ) was founded. Ono of the first orders was to design a jet trainer, which resulted in the Fokker S.14. This was the first pure jet trainer of the world. Jet trainers at that time were two seat versions of existing aircraft. One of the arguments was that the gap between the propeller trainer and the jet was considered to large. The S.14 was an easy to fly and stable aircraft, with low maintenance costs.
May 19, 1951 the prototype, registered K-1 was ready for its first flight. Fokker chief test pilot, Gerben Sonderman, noticed some problems with the landing gear and made a safe precaution landing. After a repair of several hours the aircraft was finished and the testing continued, now the landing gear would lower, so a safe belly landing was made.
July 115, 1951 the prototype was on display at the Paris air show.
It was equipped with a Rolls Royce Derwent V rated 1575 kg thrust. The RNlAF ordered 20 examples in 1952. There was also foreign interest from Sweden and Fairchild obtained licence rights, fifty examples were to be delivered to Brazil, forty-five of this order would be built by Fokker - Brazil. Alas the USA MDAP program became a problem, because of the mass deliveries of the Lockheed T-33.
because also the Fouga Magister was released, the chances for the Fokker S.14 as advanced trainer became almost zero.
It was decided to to equip the prototype with the more powerful Rolls Royce Nene 3 rated 2315 kg thrust. This improved the performance of the aircraft and thus the aircraft was more suitable for the advanced training.
This version, also known as Machtrainer II, made its maiden flight on October 23, 1953. No orders followed the release and the aircraft entered service August 21, 1961 as PH-XIV of the Nationaal Lucht- en Ruimtevaart Laboratorium. Later the aircraft was preserved and donated to the Aviodome museum at Schiphol [nowadays Aviodrome at Lelystad air port}
