United Airlines Flight 232 was a regularly scheduled United Airlines flight from Stapleton International Airport in Denver to O'Hare International Airport in Chicago, continuing to Philadelphia International Airport. On July 19, 1989, the DC-10 serving the flight crash-landed at Sioux Gateway Airport in Sioux City, Iowa, after suffering a catastrophic failure of its tail-mounted engine due to an unnoticed manufacturing defect in the engine's fan disk, which resulted in the loss of all flight controls. Of the 296 passengers and crew on board, 112 died during the accident, while 184 people survived. Thirteen of the passengers were uninjured. It was the deadliest single-aircraft accident in the history of United Airlines.
In aeronautics, a spoiler is a device which intentionally reduces the lift component of an airfoil in a controlled way. Most often, spoilers are plates on the top surface of a wing that can be extended upward into the airflow to spoil the streamline flow. By so doing, the spoiler creates a controlled stall over the portion of the wing behind it, greatly reducing the lift of that wing section. Spoilers differ from airbrakes in that airbrakes are designed to increase drag without disrupting the lift distribution across the wing span, while spoilers disrupt the lift distribution as well as increasing drag.
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.
American Airlines Flight 1 was a regularly scheduled passenger flight from New York International (Idlewild) Airport in New York City to Los Angeles International Airport in Los Angeles. During takeoff on March 1, 1962, flight, the Boeing 707 rolled over and crashed into Jamaica Bay in New York City two minutes after taking off, killing all 87 passengers and eight crew members aboard. A Civil Aeronautics Board investigation determined that a manufacturing defect in the autopilot system led to an uncommanded rudder control system input, causing the accident. A number of notable people died in the crash. It was the fifth fatal Boeing 707 accident, and at the time, the deadliest. It was third of three fatal crashes during an operation of American Airlines Flight 1, and the third fatal crash involving one of American's 707s in the New York area within a three-year period after Flight 514 and Flight 1502.
Eastern Air Lines Flight 663 was a domestic passenger flight from Boston, Massachusetts, to Atlanta, Georgia, with scheduled stopovers at John F. Kennedy International Airport, New York; Richmond, Virginia; Charlotte, North Carolina; and Greenville, South Carolina. On the night of February 8, 1965, the aircraft serving the flight, a Douglas DC-7, crashed near Jones Beach State Park, New York, just after taking off from JFK Airport. All 79 passengers and five crew aboard died.
China Airlines Flight 006 was a daily non-stop flight from Taipei to Los Angeles International Airport. On February 19, 1985, the Boeing 747SP operating the flight was involved in an aircraft upset accident, following the failure of the No. 4 engine, while cruising at 41,000 ft (12,500 m). The plane rolled over and plunged 30,000 ft (9,100 m), experiencing high speeds and g-forces before the captain was able to recover from the dive, and then to divert to San Francisco International Airport.
Alliance Air Flight 7412 was a scheduled Indian domestic passenger flight from Calcutta to Delhi, operated by Indian regional airliner Alliance Air. On 17 July 2000, while on approach to its first stopover in Patna, the Boeing 737-2A8 operating the route nose-dived and crashed into a residential area in Patna, killing 60 people including 5 on the ground.
The 1965 Carmel mid-air collision occurred on December 4, 1965, when Eastern Air Lines Flight 853 (N6218C), a Lockheed Super Constellation en route from Boston Logan International Airport to Newark International Airport, collided in mid-air with Trans World Airlines Flight 42 (N748TW), a Boeing 707-131B en route from San Francisco International Airport to John F. Kennedy International Airport, over Carmel, New York, United States.
USAir Flight 427 was a scheduled flight from Chicago's O'Hare International Airport to Palm Beach International Airport, Florida, with a stopover at Pittsburgh International Airport. On Thursday, September 8, 1994, the Boeing 737 flying this route crashed in Hopewell Township, Pennsylvania while approaching Runway 28R at Pittsburgh, which was USAir's largest hub at the time.
On 4 October 1992, El Al Flight 1862, a Boeing 747 cargo aircraft of the Israeli airline El Al, crashed into the Groeneveen and Klein-Kruitberg flats in the Bijlmermeer neighbourhood of Amsterdam, the Netherlands. The accident is known in Dutch as the Bijlmerramp.
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.
Palair Macedonian Airlines Flight 301 was a scheduled international passenger flight from Skopje to Zurich, operated by Palair Macedonian, the then-flag carrier of Macedonia, now called North Macedonia. On 5 March 1993, the aircraft operating the flight, a Fokker 100, crashed shortly after taking off from Skopje Airport in snowy conditions. Out of the 97 passengers and crew members on board, only 14 survived. At the time, it was the deadliest air disaster in North Macedonia.
American Airlines Flight 514 was a training flight from Idlewild International Airport, to the Grumman Aircraft Corp. airfield. On the afternoon of August 15, 1959, the Boeing 707 operating the flight crashed near the Calverton airport, killing all five crew members aboard. This was the first accident to involve a Boeing 707, which had only gone into service in October of the previous year, and the first of three accidents involving American's 707s in the New York area within three years, followed by Flight 1502 and Flight 1.
On 17 March 1977, a British Airtours Boeing 707 being used for pilot training crashed and caught fire during its take-off roll at Glasgow Prestwick Airport. All four crew members on board survived.
