Japan Air Lines Flight 123 was a scheduled domestic passenger flight from Tokyo to Osaka, Japan. On August 12, 1985, the Boeing 747 flying the route suffered a severe structural failure and decompression 12 minutes into the flight. After flying under minimal control for a further 32 minutes, the 747 crashed in the area of Mount Takamagahara, 100 kilometres from Tokyo.
The Saab 340 is a Swedish twin-engine turboprop aircraft designed and initially produced by Saab AB and Fairchild Aircraft. It is designed to seat 30-36 passengers and, as of July 2018, there were 240 operational aircraft used by 34 different operators.
Dutch roll is an aircraft motion consisting of an out-of-phase combination of "tail-wagging" (yaw) and rocking from side to side (roll). This yaw-roll coupling is one of the basic flight dynamic modes. This motion is normally well damped in most light aircraft, though some aircraft with well-damped Dutch roll modes can experience a degradation in damping as airspeed decreases and altitude increases. Dutch roll stability can be artificially increased by the installation of a yaw damper. Wings placed well above the center of gravity, swept wings, and dihedral wings tend to increase the roll restoring force, and therefore increase the Dutch roll tendencies; this is why high-winged aircraft often are slightly anhedral, and transport-category swept-wing aircraft are equipped with yaw dampers. A similar phenomenon can happen in a trailer pulled by a car.
Aerobatic maneuvers are flight paths putting aircraft in unusual attitudes, in air shows, dogfights or competition aerobatics. Aerobatics can be performed by a single aircraft or in formation with several others. Nearly all aircraft are capable of performing aerobatics maneuvers of some kind, although it may not be legal or safe to do so in certain aircraft.
Formosa Airlines was a Taiwanese regional airline operating an extensive network of domestic routes out of its bases at Taipei Songshan Airport and Kaohsiung International Airport. Its headquarters were in Taipei.
Midwest Express Airlines Flight 105 was a scheduled domestic passenger flight that crashed into an open field in Oak Creek, Wisconsin shortly after taking off from General Mitchell International Airport on September 6, 1985. The airplane, a Douglas DC-9, was carrying 31 passengers and crew. None of them survived the crash.
Rex Airlines Pty Ltd is an Australian regional airline based in Mascot, New South Wales. It operates scheduled regional and domestic services, using using both jet and turboprop aircraft.
Aeroflot Flight 593 was a passenger flight from Sheremetyevo International Airport, Moscow, Russia, to Kai Tak Airport in Hong Kong. On 23 March 1994, the aircraft operating the route, an Airbus A310-304 flown by Aeroflot, crashed into the Kuznetsk Alatau mountain range in Kemerovo Oblast, killing all 63 passengers and 12 crew members on board.
Crossair Flight 498 was a scheduled commuter flight from Zürich, Switzerland, to Dresden, Germany. On 10 January 2000, the Saab 340B operating the flight crashed two minutes after takeoff in the Swiss municipality of Niederhasli on 10 January 2000, killing all 10 passengers and crew. It was one of two fatal crashes for Crossair during its existence; the other was Crossair Flight 3597 which crashed less than 2 years later during approach to Zurich.
An aircraft in flight is free to rotate in three dimensions: yaw, nose left or right about an axis running up and down; pitch, nose up or down about an axis running from wing to wing; and roll, rotation about an axis running from nose to tail. The axes are alternatively designated as vertical, lateral, and longitudinal respectively. These axes move with the vehicle and rotate relative to the Earth along with the craft. These definitions were analogously applied to spacecraft when the first crewed spacecraft were designed in the late 1950s.
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 April 4, 1979, at or around 9:48 p.m. Eastern Standard Time, 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 a successful emergency landing at Detroit Metropolitan Airport.
KLM Cityhopper Flight 433 was a Saab 340B, registered as PH-KSH, which crashed during an emergency landing on 4 April 1994 and killing 3 occupants, including the captain. Flight 433 was a routine scheduled flight from Amsterdam, the Netherlands, to Cardiff, Wales. The accident was caused by inadequate pilot training and a faulty sensor, leading to loss of control during go-around.
On 26 May 2008, Moskovia Airlines Flight 9675, a Moskovia Airlines An-12 cargo aircraft crashed near Chelyabinsk, Russia. After taking off for a flight to Perm, it turned back due to a fire on board and crashed 11 kilometres from the airport, killing all nine crew members.
On 11 February 1978, Pacific Western Airlines Flight 314, a Boeing 737-200, crashed at Cranbrook/Canadian Rockies International Airport, near Cranbrook, British Columbia, Canada, killing 43 of the 49 people on board.
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.
On April 4, 1955, a United Airlines Douglas DC-6 named Mainliner Idaho crashed shortly after taking off from Long Island MacArthur Airport, in Ronkonkoma, Islip, New York, United States.
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.
American Eagle is a brand name for the regional branch of American Airlines, under which six individual regional airlines operate short- and medium-haul feeder flights. Three of these airlines, Envoy Air, Piedmont Airlines, and PSA Airlines, are wholly owned subsidiaries of the American Airlines Group. American Eagle's largest hub is Charlotte Douglas International's Concourse E, which operates over 340 flights per day, making it the largest regional jet operation in the world.
Aeroflot Flight 2415 was a regularly scheduled passenger flight from Moscow to Leningrad that crashed shortly after takeoff on 28 November 1976. The cause of the accident was attributed to crew disorientation as a result of artificial horizon failure in low visibility conditions.
Loganair Flight 6780 was a scheduled domestic flight from Aberdeen Airport to Sumburgh Airport in the Shetland Islands, Scotland. On 15 December 2014, the Saab 2000 operating the flight was struck by lightning during the approach, and then plunged faster than the aircraft's maximum operating speed. The aircraft came within 1,100 feet (340 m) of the North Sea before the pilots recovered and returned to Aberdeen. All 33 passengers and crew were unharmed.
