Fokker S-13

The Fokker S.13 Universal Trainer was a twin-engine propeller aircraft for training, designed by Fokker and first flown in 1949, which did not go into production. In the early years after the Second World War, Fokker was resurrected with help from the Dutch national institute for aircraft development and expected strong demand for training aircraft, so it worked out a range of designs, one of which became the S.13. The Universal Trainer was meant for multi-engine, navigation, paradropping and radiotelephony training, and Fokker also envisaged a floatplane version, the S.13W, and a civil version. The prototype, registered PH-NDW and later PH-NEI, first flew in 1949, was easy to handle and strong, and the Dutch armed forces intended to buy it, but shortly before the decision they were given Beechcraft Model 18s almost free under the Mutual Defense Assistance Pact. With no other buyers Fokker terminated the programme, and the only S.13 was transferred to the NIV in 1953 and later donated to the aerospace faculty of the Delft technical university.
