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.^[source]De Havilland Canada Dash 8 · Development / Initial development; only the objects and conditions stated in this passage

The production of the Dash 8 Series 100 stopped in 2005, and that of the Series 200 and 300 in 2009.^[source]De Havilland Canada Dash 8 · Development / Production; only the objects and conditions stated in this passage

At the February 2016 Singapore Airshow , Bombardier announced a high-density, 90-seat layout of the Q400, which would enter service in 2018; keeping the 28 in (71 cm) seat pitch of the Nok Air 86-seats, an extra row of seats is allowed by changing the configuration of the front right door and moving back the aft pressure bulkhead . The payload is increased by 2,000 pounds (910 kg) and the aircraft maintenance check intervals are increased: 800 hours from 600 for an A-check and 8,000 hours from 6,000 for a C-check. By August 2018, the 90-seat variant was certified before delivery to launch customer SpiceJet later in the same year. In March 2021, EASA certified the 90-seat variant for European operations; DHC believed that there were opportunities with prospective European customers as of 2021 .^[source]De Havilland Canada Dash 8 · Development / High-density, 90-seat Q400; only the objects and conditions stated in this passage

The Dash 8 design has better cruise performance than the Dash 7, is less expensive to operate, and is much less expensive to maintain, due largely to having only two engines. It is a little noisier than the Dash 7 and cannot match the STOL performance of its earlier DHC forebears, although it is still able to operate from small airports with runways 3,000 ft (910 m) long, compared to the 2,200 ft (670 m) required by a fully laden Dash 7.^[source]De Havilland Canada Dash 8 · Design; only the objects and conditions stated in this passage

The aircraft has been delivered in four series. The Series 100 has a maximum capacity of 39, the Series 200 has the same capacity but offers more powerful engines, the Series 300 is a stretched, 50-seat version, and the Series 400 is further stretched to a maximum of 90 passengers. Models delivered after 1997 have cabin noise suppression and are designated with the prefix "Q". Production of the Series 100 ceased in 2005, followed by the 200 and 300 in 2009, leaving the Q400 as the only series still in production.^[source]De Havilland Canada Dash 8 · Variants; only the objects and conditions stated in this passage

The Series 100 was the original 37-39 passenger version of the Dash 8 that entered service in 1984. The original engine was the Pratt & Whitney Canada PW120 and later units used the PW121.

The Series 200 aircraft maintained the same 37–39 passenger airframe as the original Series 100, but was re-engined for improved performance. The Series 200 used the more powerful Pratt & Whitney Canada PW123 engines rated at 2,150 shp (1,600 kW).^[source]De Havilland Canada Dash 8 · Variants / Series 200; only the objects and conditions stated in this passage

The Series 300 introduced a longer airframe that was stretched 3.43 metres (11.3 ft) over the Series 100/200 and has a passenger capacity of 50–56. The Series 300 also used the Pratt & Whitney Canada PW123 engines. Rated engine power is between 2,380 shp (1,774 kW) and 2,500 shp (1,864 kW). Design service life is 80,000 flight cycles. Under an extended service program launched in 2017, the service life of Dash 8-300 is extended by 50 percent, or approximately 15 years, to 120,000 flight cycles.^[source]De Havilland Canada Dash 8 · Variants / Series 300; only the objects and conditions stated in this passage

The Series 400 introduced an even longer airframe that was stretched 6.83 metres (22.4 ft) over the Series 300 (10.26 metres (33.7 ft) over the Series 100/200), had slightly more wing span due to a larger wing section inboard of the engines, a stouter T-tail and had a passenger capacity of 68–90. The Series 400 uses Pratt & Whitney Canada PW150A engines rated at 4,850 shp (3,620 kW). The aircraft has a cruise speed of 360 knots (667 km/h), which is 60–90 knots (111–166 km/h) higher than its predecessors. The maximum operating altitude is 25,000 ft (7,600 m) for the standard version, although a version with drop-down oxygen masks is offered, which increases maximum operating altitude to 27,000 ft (8,200 m).^[source]De Havilland Canada Dash 8 · Variants / Series 400; only the objects and conditions stated in this passage

On September 9, 2007, the crew of SAS Flight 1209, en route from Copenhagen to Aalborg , reported problems with the locking mechanism of the right side landing gear, and Aalborg Airport was prepared for an emergency landing. Shortly after touchdown, the right main gear collapsed and the airliner skidded off the runway while fragments of the right propeller shot against the cabin, and the right engine caught fire. Of 69 passengers and four crew on board, 11 were sent to hospital, five with minor injuries. The accident was filmed by a local news channel (TV2-Nord) and broadcast live on national television.^[source]De Havilland Canada Dash 8 · Accidents and incidents / Major landing gear accidents / Accidents in 2007; only the objects and conditions stated in this passage

On October 27, 2007, Scandinavian Airlines Flight 2867 en route from Bergen to Copenhagen had severe problems with the landing gear during landing in Kastrup Airport. The right wing gear did not deploy properly (or partially), and the aircraft skidded off the runway in a controlled emergency landing. The Q400 was carrying 38 passengers, two infants, and four crew members on board. No injuries were reported. The next day, SAS permanently removed its entire Dash 8 Q400 fleet from service. In a press release on October 28, 2007, the company's president said: "Confidence in the Q400 has diminished considerably and our customers are becoming increasingly doubtful about flying in this type of aircraft. Accordingly, with the Board of Directors' approval, I have decided to immediately remove Dash 8 Q400 aircraft from service." The preliminary Danish investigation determined the latest Q400 incident was unrelated to the airline's earlier corrosion problems, in this particular case caused by a misplaced O-ring found blocking the orifice in the restrictor valve .^[source]De Havilland Canada Dash 8 · Accidents and incidents / Major landing gear accidents / Accidents in 2007; only the objects and conditions stated in this passage

In all, eight Q400s had landing gear failures while landing during 2007: four in Denmark, one in Germany, one in Japan, one in Lithuania, and one in South Korea. In November 2007, it was revealed that the Swedish Civil Aviation Administration had begun an investigation and found Scandinavian Airlines System culpable of cutting corners in its maintenance department. The airline reportedly made 2,300 flights in which safety equipment was not up to standard. On March 10, 2008, SAS ordered 27 more aircraft from Bombardier in a compensation deal: 14 Q400 NextGen turboprops and 13 CRJ900 jets.^[source]De Havilland Canada Dash 8 · Accidents and incidents / Major landing gear accidents / Accidents in 2007; only the objects and conditions stated in this passage

On October 13, 2011, Airlines PNG Flight 1600 , Dash 8-103 P2-MCJ, was on approach to Madang Airport when the first officer accidentally pulled the power levers through the flight idle setting and into the beta setting while trying to reduce airspeed. In beta, which is intended for ground operations and slowing the aircraft after landing, the variable-pitch props transition to flat pitch. High-speed airflow through the improperly configured props caused them to overspeed and drive the engines, which caused engine damage and a total loss of engine power. The aircraft crashed during the ensuing off-airport forced landing attempt; both pilots, the flight attendant, and a single passenger survived with injuries, while the other 28 passengers died.^[source]De Havilland Canada Dash 8 · Accidents and incidents / Propeller overspeed incidents; only the objects and conditions stated in this passage
