The De Havilland Canada DHC-8, commonly known as the Dash 8, is a series of turboprop-powered regional airliners, introduced by de Havilland Canada (DHC) in 1984. DHC was bought by Boeing in 1986, then by Bombardier in 1992, then by Longview Aviation Capital in 2019; Longview revived the De Havilland Canada brand. Powered by two Pratt & Whitney Canada PW100-series engines, it was developed from the Dash 7 with improved cruise performance and lower operational costs, but without STOL performance. The Dash 8 was offered in four sizes: the initial Series 100 (1984–2005), the more powerful Series 200 (1995–2009) with 37–40 seats, the Series 300 (1989–2009) with 50–56 seats, and Series 400 (1999–2022) with 68–90 seats. The QSeries are post-1997 variants fitted with active noise control systems.
