The de Havilland Canada DHC-7, popularly known as the Dash 7, is a turboprop-powered regional airliner with short take-off and landing (STOL) performance. Variants were built with 50–54 seats. It first flew in 1975 and remained in production until 1988 when the parent company, de Havilland Canada, was purchased by Boeing in 1986 and later sold to Bombardier. In 2006 Bombardier sold the type certificate for the aircraft design to Victoria-based manufacturer Viking Air.
