De Havilland Canada Dash 7

The de Havilland Canada DHC-7, popularly known as the Dash 7, is a four-engined turboprop regional airliner with short takeoff and landing performance, built with 50 to 54 seats. De Havilland Canada, already known for the Beaver and Twin Otter, aimed it at city-centre and austere airports, with an original specification for 40 passengers from 2,000 foot runways and low noise. In other respects it was essentially a larger, four-engine Twin Otter, with a pressurized circular fuselage, landing gear folding forward into the inner nacelles and a large T-tail. It first flew in 1975 and stayed in production until 1988, when the parent company had been bought by Boeing and sold on to Bombardier. The line delivered 114 aircraft, and Bombardier sold the type certificate to Viking Air in 2006.
