The de Havilland Canada DHC-1 Chipmunk is a tandem, two-seat, single-engine trainer aircraft which was the standard primary trainer for the Royal Canadian Air Force, Royal Air Force and several other air forces through much of the post-Second World War years. The de Havilland Chipmunk was the first postwar aviation project of de Havilland Canada.

Design and development
The Chipmunk was designed to succeed the de Havilland Tiger Moth biplane trainer that was widely used during the Second World War. Wsiewołod Jakimiuk, a Polish engineer, created the first indigenous design of the aircraft at de Havilland Aircraft of Canada Ltd. It is an all-metal, low wing, tandem two-place, single engine aircraft with a conventional tail wheel landing gear and fabric-covered control surfaces. The wing is also fabric-covered aft of the spar. A clear perspex canopy covers the pilot/student (front) and instructor/passenger (rear) positions. The Chipmunk prototype, flew for the first time at Downsview, Toronto on 22 May 1946 with Pat Fillingham, test pilot from the parent de Havilland company, at the controls. The production version of the airplane was powered by a 145 hp (108 kW) in-line de Havilland Gipsy Major 8 engine while the prototype was powered by a 145 hp (108 kW) de Havilland Gipsy Major 1C.
Two Chipmunk aircraft were evaluated by the
Aeroplane and Armament Experimental Establishment (A&AEE) at RAF Boscombe Down. As a result, the fully-aerobatic Chipmunk version was ordered as basic trainer for the Royal Air Force. The Royal Canadian Air Force also adopted the Chipmunk as basic trainer.
British-built and early Canadian-built Chipmunks are notably different from the later Canadian-built RCAF/Lebanese versions. The later Canadian-built airplanes have a
bubble canopy, while early Canadian, and all Portuguese and British examples have the multi-panelled sliding canopy, the rearmost panels of which are bulged for better instructor visibility.
The Chipmunk was a great military success. 26 countries flown the DHC-1 as trainer aircraft, selfs the Belgian Air Force got 2 aircraft for evaluations but it’s the Stampe & Vertongen SV4bis who was choosen to replace the Tiger Moth fleet.
From the 1950s onward, the Chipmunk also became a popular civilian aircraft, being used for training,
aerobatics and crop spraying. Most civilian aircraft are ex-military like the two Belgian plane that became respectively OO-PSC (ex C1) and OO-MER (ex C2).
Today, over 500 DHC-1 Chipmunk (affectionately known as "Chippie") remain airworthy with more being rebuilt every year…
