The DHC-8 Dash 8 is a series of turboprop-powered regional airliners, introduced
by de Havilland Canada (DHC) in 1984. DHC was later bought by Boeing in 1988,
then by Bombardier in 1992; the program is to be resold to Viking Air parent
Longview Aviation Capital by late 2019. Powered by two Pratt & Whitney Canada
PW100s, it was developed from the Dash 7 with improved cruise performance,
lowered operational costs but without STOL performance. Three sizes were
offered: initially the 37–40 seat -100 until 2005 and the more powerful -200
from 1995, the stretched 50–56 seats -300 from 1989, both until 2009, and the
68–90 seats -400 from 1999, still in production. The Q Series are post-1997
variants with quieter cabins.
In the 1970s, de Havilland Canada had invested heavily in its Dash 7 project,
concentrating on STOL and short-field performance, the company's traditional
area of expertise. Using four medium-power engines with large, four-bladed
propellers resulted in comparatively lower noise levels, which combined with its
excellent STOL characteristics, made the Dash 7 suitable for operating from
small in-city airports, a market DHC felt would be compelling. However, only a
handful of air carriers employed the Dash 7, as most regional airlines were more
interested in operational costs than short-field performance.
In 1980, de Havilland responded by dropping the short-field performance
requirement and adapting the basic Dash 7 layout to use only two, more powerful
engines. Its favoured engine supplier, Pratt & Whitney Canada, developed the new
PW100 series engines for the role, more than doubling the power from its PT6.
Originally designated the PT7A-2R engine, it later became the PW120. When the
Dash 8 rolled out on April 19, 1983, more than 3,800 hours of testing had been
accumulated over two years on five PW100 series test engines. The Dash 8 first
flight was on June 20, 1983.
Certification of the PW120 followed on December 16, 1983.
