context_page_description: 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 in 1984. DHC was later bought by Boeing in 1988, then by Bombardier in 1992; then by Longview Aviation Capital in 2019, reviving the de Havilland Canada brand. Powered by two Pratt & Whitney Canada PW100s, it was developed from the Dash 7 with improved cruise performance and lower 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 fitted with active noise control systems.
context_section_description: In September 2007, two separate accidents of similar landing gear failures occurred within four days of each other on Scandinavian Airlines (SAS) Dash 8-Q400 aircraft. A third accident occurred in October 2007, leading to the withdrawal of the type from the airline's fleet.
  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.
  Three days later on September 12, Scandinavian Airlines Flight 2748 from Copenhagen to Palanga had a similar problem with the landing gear, forcing the aircraft to land in Vilnius international airport (Lithuania). No passengers or crew were injured. Immediately after this accident SAS grounded all 33 Q400 airliners in its fleet and, a few hours later, Bombardier recommended that all Q400s with more than 10,000 flights be grounded until further notice. This affected about 60 aircraft, out of 140 Q400s then in service.
  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.
  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.
  On August 19, 2018, a Q400-200 of LC Peru on a flight from Lima to Ayacucho had to return to Lima and make an emergency landing due to a nose gear that could not be lowered. The aircraft landed without the nose gear down.
  On November 15, 2018, a Q300-315 belonging to PAL Airlines was unable to lower its nose gear while trying to land at Deer Lake, Newfoundland, diverted to Stephenville, Newfoundland and carried out a nose gear up landing.
