De Havilland BC DH.90 Dragonfly

The De Havilland BC DH.90 Dragonfly was a six passenger piston-engined passenger airliner or mail plane built by De Havilland British Columbia between 1937 and 1939, derived from the the DH.90 Dragonfly luxury touring biplane of DHBC's parent company, De Havilland Aircraft of the United Kingdom.

= Description = The original British version, the DH.90A Dragonfly, was a four-passenger luxury touring biplane derived from the design of the DH.89 Dragon Rapide. When the Royal Mail of British Columbia expressed interest in a new, fast mailplane, DHBC adapted the DH.90 design for the air mail role. Designated the DH.90B Dragonfly, fully half of the sixteen built were delivered to the Royal Mail; likewise without passenger accomodation other than four removable jump-seats were the four built for the Royal BC Constabulary. Three were built for airlines with accomodations for six passengers, and one was built as an executive transport for the BC Electric Company.

The British-made DH.90A was powered by two 130 hp De Havilland (UK) Gipsy Major I engines, but those built in British Columbia were powered by Hoffar Aero Engines' 165 hp HB-6A Dragon VI-M engine.
