Fokker S.14
Rob Arndt
After the occupation of WWII the fokker factory started producing
airplanes again, backed by the government. Initially the main focus
was on trainer airplanes. After a couple of prop designs (like S.11
and S.13) Fokker came with it's S.14 jet trainer.
The student and instructor sat next to each-other in Martin-Baker
ejection seats. The plane was powered by a Rolls-Royce Derwent III
engine. It had straight wings. First flight took place on May 19th
1951. The Fairchild factory bought licence rights for production, but
the type was overshadowed by the Lockheed T-33 and only Holland used
the type in limited numbers. (appr. 20)

The Fokker S.14 Mach-Trainer secured its place in aviation history by
being the first Fokker-designed jet aircraft, the first jet-propelled
trainer designed as such, and the first aircraft of its type to enter
production.
The low-wing all-metal S.14 was powered by a Rolls-Royce Derwent
turbojet with a bifurcated inlet in the nose. The outlet was in the
extreme tail, aft of the horizontal tail surfaces, which were set
somewhat aft of the fin and rudder. The nosewheel of the tricycle
landing gear retracted forwards into the underside of the nose while
the main units retracted inwards into the undersides of the wings.
Pupil and instructor were seated side-by-side under a short, broad
raised canopy set well forward on the circular-section fuselage.
Martin-Baker ejector seats were standard.
Test pilot Gerben Sonderman made the first test flight on 19 May 1951.
On a second flight during the same day the landing gear failed and the
prototype was damaged in the subsequent belly-landing. However, the
aircraft was repaired and displayed at the 1951 Paris Salon in June of
that year.
A series of 20 S.14s was ordered by the Royal Dutch air arm, the
Koninklike Luchtmacht, the first being flown initially on 15 January
1955. The prototype bore the serial K-1 and was powered by a Derwent V
engine, while the production machines were serialled from L-1 to L-20
and had Derwent VIIIs. The S.14s served at four air stations: Twenthe,
Ypenburg, Gilze-Rijen and Soesterberg. Aircraft L-4 was demonstrated
in the USA during 1955, but crashed on 20 October that year at
Hagerstown, Maryland, killing Gerben Sonderman. Aircraft L-8 took part
in the London-Paris air race, known as the Arch to Arc since it
started at Marble Arch and ended at the Arc de Triomphe. The last two
S.14s were withdrawn from Dutch service on 29 March 1965. Serialled
L-17 and L-19, they are preserved at the Museums at Schiphol and
Soesterberg respectively.
The original K-1 prototype was re-engined with a 2313kg thrust Rolls-
Royce Nene 3 engine in 1953 and given the specially selected civil
registration PH-XIV on 24 October 1960. It was then used by the Lucht
en Ruuimtevaart Laboratorium (Dutch National Aeronautical and Space
Laboratory) until scrapped on 4 March 1966.
