The De Havilland Canada DHC-8,[2] 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 PW150s, 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 three sizes: the initial Series 100 (1984–2005) and the more powerful Series 200 (1995–2009) with 37-40 seats, the Series 300 (1989–2009) with 50-56 seats, and Series 400 (1999-Present) with 68-90 seats. The QSeries (Q for quiet) are post-1997 variants fitted with active noise control systems.
