By 2007 Viking Air owned the rights to all early de Havilland Canada products from the Chipmunk through to Beaver, Otter, Caribou, Twin Otter and Dash 7.
Viking Air completed a ten-minute maiden flight of the first new-build DHC-6 Series 400 Twin Otter on February 16, 2010. The aircraft (c/n 845) flew from the company’s assembly facility at Calgary in Alberta. It has been assigned the registration C-FMJO and is configured with a commuter cabin and will be delivered to launch customer Zimex Aviation of Switzerland for use on oil and gas industry contracts throughout North Africa.
De Havilland Canada ended production of the Twin Otter in 1988 after c/n 844 was rolled out. Viking announced the re-launch of the type and in 2010 ten Twin Otter 400s were in various stages of assembly at Calgary with production ramping up to build one-and-a-half aircraft every four weeks.
