      history 
      by Jeff VanDerford 
       
      History: Developed just after World War II, the DHC-1 Chipmunk was the 
      first aircraft designed by de Havilland of Canada to replace the de 
      Havilland Tiger Moth as a single-engine basic trainer. The Chipmunk first 
      flew on 22 May 1946. Initially, 218 Chipmunks were built for the Royal 
      Canadian Air Force, followed, after a change to the Gipsy Major 8 engine, 
      by 735 planes for the RAF’s primary pilot training bases. These were 
      designated as T 10s. 
       
      The British version also differed by being fully aerobatic and having a 
      sliding, multi-panelled canopy rather than the ‘bubble’ typical in Canada. 
      Another 217 of the versatile, easily-mastered Chipmunks were built for 
      export sale, and 60 were built under license in Portugal. Not fully 
      retired until 1996, many examples are still flying in private hands 
      worldwide.
