(also called
Fokker F.22
) was a 1930s
Dutch
four-engined 22-passenger airliner designed and built by
Fokker
.
Development
[
edit
]
Developed as a smaller version of the
Fokker F.XXXVI
the F.XXII is a high-wing cantilever monoplane with a fixed tailwheel landing gear. It was powered by four
Pratt & Whitney Wasp
radial piston engines mounted in the wing leading edge. The first aircraft registered
PH-AJP
first flew in 1935, and was followed by two production aircraft all for KLM. A fourth aircraft was built for the
Swedish
airline
AB Aerotransport
.
A version with retractable landing gear and powered by two 650 hp Gnome-Rhone 9KF engines, the
F.XXIII
(or
F.23
), was developed in 1935. The increased engine power allowed a higher weight and increased speed by 12 mph (19 km/h), but this reduced range from 1,095 mi (1,762 km) to 980 mi (1,577 km). The heavier engines did not justify the revised performance, so the F.XXIII was never built.
Operational history
[

]
One KLM aircraft crashed in July 1935 and the other two continued in service until August 1939, when they were sold to British American Air Services and
Scottish Aviation
in the United Kingdom. A month later the British American Air Services aircraft was also acquired by Scottish Aviation as a navigation trainer. In October 1941, they were both impressed into service with the
Royal Air Force
and used as transports and crew trainers. One aircraft survived the war to be returned to Scottish Aviation who used it for services between Prestwick and Belfast until it was grounded at the end of 1947.
The Swedish aircraft, which was named
Lappland
, flew a regular Amsterdam?Malmo service until it was destroyed in an accident in June 1936.
Airspeed Ltd.
in
Great Britain
arranged a license to build F.XXIIs for the British market as the
Airspeed AS.16
, but no orders were received.
