The McDonnell Douglas MD-80 is a series of five-abreast single-aisle airliners developed by McDonnell Douglas. It was produced by the developer company until August 1997 and then by Boeing Commercial Airplanes. The MD-80 was the second generation of the DC-9 family, originally designated as the DC-9-80 and later stylized as the DC-9 Super 80 . Stretched, enlarged wing and powered by higher bypass Pratt & Whitney JT8D-200 engines, the aircraft program was launched in October 1977. The MD-80 made its first flight on October 18, 1979, and was certified on August 25, 1980. The first airliner was delivered to launch customer Swissair on September 13, 1980, which introduced it into service on October 10, 1980.
The McDonnell Douglas MD-11 is an American tri-jet wide-body airliner manufactured by American manufacturer McDonnell Douglas (MDC) and later by Boeing. Following DC-10 development studies, the MD-11 program was launched on December 30, 1986. Assembly of the first prototype began on March 9, 1988. Its maiden flight occurred on January 10, 1990, and it achieved Federal Aviation Administration (FAA) certification on November 8. The first delivery was to Finnair on December 7 and it entered service on December 20, 1990.
Delta Air Lines Flight 1141 was a scheduled domestic passenger flight between Dallas Fort Worth International Airport (DFW), Texas, and Salt Lake City International Airport, Utah. On August 31, 1988, the flight, using a Boeing 727-200 series aircraft, crashed during takeoff at DFW, resulting in 14 deaths and 76 injuries among the 108 on board. The cause of the crash was that the crew failed to configure the airplane's flaps or slats for takeoff. The aircraft's take-off warning system (TOWS) also malfunctioned and failed to warn the crew of the problem. Recordings from the cockpit voice recorder revealed that the crew had improperly engaged in casual conversation on various matters unrelated to the operation of the flight, which may have distracted them from properly performing their duties. The recordings, which were broadcast repeatedly by the press, proved so embarrassing that a law was subsequently passed to prohibit the release of cockpit voice recordings. Since the passage of that law, only written transcripts have been released rather than the voice recordings themselves.
American Airlines Flight 1420 was a flight from Dallas/Fort Worth International Airport (DFW) to Little Rock National Airport in the United States. On June 1, 1999, the McDonnell Douglas MD-82 operating as Flight 1420 overran the runway upon landing in Little Rock and crashed. Nine of the 145 people aboard were immediately killed—the captain and eight passengers. Two more passengers died in the hospital in the following weeks.
Air Canada Flight 797 was an international passenger flight operating from Dallas/Fort Worth International Airport to Montréal–Dorval International Airport, with an intermediate stop at Toronto Pearson International Airport.
On August 16, 1987, a McDonnell Douglas MD-82, operating as Northwest Airlines Flight 255, crashed shortly after takeoff from Detroit Metropolitan Airport, about 8:46 pm EDT, resulting in the deaths of all six crew members and 148 of the 149 passengers, along with two people on the ground. The sole survivor was a 4-year-old girl who sustained serious injuries. It was the second-deadliest aviation accident at the time in the United States. It is also the deadliest aviation accident to have a sole survivor, the deadliest aircraft accident in the history of the state of Michigan, and the worst crash in the history of Northwest Airlines.
Scandinavian Airlines System Flight 751 was a regularly scheduled Scandinavian Airlines passenger flight from Stockholm, Sweden, to Warsaw, Poland, via Copenhagen, Denmark. On 27 December 1991, a McDonnell Douglas MD-81 operating the flight, registration OY-KHO, piloted by Danish Captain Stefan G. Rasmussen (44) and Swedish first officer Ulf Cedermark (34), both experienced pilots with 8,000 and 3,000 flight hours, respectively, was forced to make an emergency landing in a field near Gottröra, Sweden. Ice had collected on the wings' inner roots before takeoff, broke off, and was ingested into the engines as the aircraft became airborne on takeoff, ultimately disabling both engines. All 129 passengers and crew aboard survived.
China Northern Airlines Flight 6136 (CBF6136/CJ6136) was a Chinese domestic passenger flight from Beijing Capital International Airport to Dalian Zhoushuizi International Airport. On 7 May 2002, the McDonnell Douglas MD-82 operating the flight crashed into the bay near Dalian shortly after the pilot reported fire on board, killing all 103 passengers and 9 crew members. The cause of the fire was later determined to be arson.
American Airlines Flight 96 (AA96/AAL96) was a regular domestic flight operated by American Airlines from Los Angeles to New York via Detroit and Buffalo. On June 12, 1972, after takeoff from Detroit, Michigan, the left rear cargo door of the McDonnell Douglas DC-10-10 operating the flight blew open and broke off above Windsor, Ontario, the accident is thus sometimes referred to as the Windsor incident, although according to the NTSB it was an accident, not an incident.
USAir Flight 1016 was a regularly scheduled flight in the southeastern United States, between Columbia, South Carolina, and Charlotte, North Carolina. On July 2, 1994, the flight encountered heavy thunderstorms and microburst-induced windshear while attempting to land, and crashed into heavy trees and a private residence near the airport. The crash and ensuing fire caused 37 fatalities and seriously injured 20 others.
The McDonnell Douglas DC-9 is an American five-abreast, single-aisle aircraft designed by the Douglas Aircraft Company. It was initially produced as the Douglas DC-9 prior to August 1967, after which point the company had merged with McDonnell Aircraft to become McDonnell Douglas. Following the introduction of its first jetliner, the high-capacity DC-8, in 1959, Douglas was interested in producing an aircraft suited to smaller routes. As early as 1958, design studies were conducted; approval for the DC-9, a smaller all-new jetliner, came on April 8, 1963. The DC-9-10 first flew on February 25, 1965, and gained its type certificate on November 23, to enter service with Delta Air Lines on December 8.
FedEx Express Flight 647 was a flight between Metropolitan Oakland International Airport, Oakland, California and Memphis International Airport, Memphis, Tennessee in the United States, that crashed during landing on December 18, 2003.
TWA Flight 841 was a scheduled passenger flight from John F. Kennedy International Airport, New York City, en route to Minneapolis-Saint Paul International Airport in Minneapolis, Minnesota. On the evening of April 4, 1979 while flying over Saginaw, Michigan, the Boeing 727-31 airliner began a sharp, uncommanded roll to the right, and subsequently went into a spiral dive. The pilots were able to regain control of the aircraft and made an emergency landing at Detroit Metropolitan Airport.
Spanair Flight 5022 or (JK5022/JKK5022) was a scheduled domestic passenger flight from Barcelona–El Prat Airport to Gran Canaria Airport, Spain, with a stopover in Madrid–Barajas Airport that crashed just after take-off from runway 36L at Madrid-Barajas Airport to Gran Canaria Airport at 14:24 CEST (12:24 UTC) on 20 August 2008. The aircraft was a McDonnell Douglas MD-82, registration EC-HFP. Of the 172 passengers and crew on board, 154 died and 18 survived.
Alitalia Flight 404 (AZ404/AZA404) was an international passenger flight scheduled to fly from Linate Airport in Milan, Italy, to Zürich Airport in Zürich, Switzerland, which crashed on 14 November 1990. The McDonnell Douglas DC-9-32, operated by Alitalia, crashed into the woodlands of Weiach as it approached Zurich Airport, killing all 46 occupants on board.
FedEx Express Flight 80 was a scheduled cargo flight from Guangzhou Baiyun International Airport in China, to Narita International Airport in Narita, Chiba Prefecture, Japan. On March 23, 2009, the McDonnell Douglas MD-11F (N526FE) operating the flight crashed at 6:48 am JST, while attempting a landing on Runway 34L in gusty wind conditions. The aircraft became destabilized at flare and touchdown resulting in an unrecovered "bounced" landing with structural failure of the landing gear and airframe following pilot error due to poor training for bounced landings. The plane came to rest off the runway, inverted, and burning fiercely. The captain and first officer, the jet's only occupants, were both killed.
Throughout a normal flight, a pilot controls an aircraft through the use of flight controls including maintaining straight and level flight, as well as turns, climbing, and descending. Some controls, such as a "yoke" or "stick" move and adjust the control surfaces which affects the aircraft's attitude in the three axes of pitch, roll, and yaw. Other controls include those for adjusting wing characteristics and those that control the power or thrust of the propulsion systems. The loss of primary control systems in any phase of flight is an emergency. Aircraft are not designed to be flown under such circumstances; however, some pilots faced with such an emergency have had limited success flying and landing aircraft with disabled controls.
In aeronautics, loss of control (LOC) is the unintended departure of an aircraft from controlled flight and is a significant factor in several aviation accidents worldwide. In 2015 it was the leading cause of general aviation accidents. Loss of control may be the result of mechanical failure, external disturbances, aircraft upset conditions, or inappropriate crew actions or responses.
Delta Air Lines Flight 1086 was a scheduled Delta Air Lines domestic passenger flight between Atlanta and New York's LaGuardia Airport. On March 5, 2015, the McDonnell Douglas MD-88 aircraft veered off the runway shortly after landing at LaGuardia Airport in New York City. The plane ran up the seawall berm and struck the perimeter fence, sliding along it for approximately 940 feet (290 m) before coming to rest with the nose of the aircraft hanging over the berm above Flushing Bay. There were no fatalities, although 29 people suffered minor injuries. The aircraft was seriously damaged and written off.
Delta Air Lines Flight 1288 was a regularly scheduled flight from Pensacola, Florida to Atlanta, Georgia. On July 6, 1996, the aircraft serving the flight, a McDonnell Douglas MD-88, was on takeoff roll from Runway 17 at Pensacola when it experienced an uncontained, catastrophic turbine engine failure that caused debris from the front compressor hub of the left engine to penetrate the left aft fuselage. The cause of the engine failure was found to have been a fault in the manufacture of the fan. The failure of the airline to spot the resulting crack in the blade was a contributing factor.
