An in-flight breakup is a catastrophic failure of an aircraft structure that causes it to break apart in mid-air. This can result in the death of all occupants and the destruction of the aircraft. In-flight breakups are rare but devastating events that can be caused by various factors.
Faults in the design or manufacturing of the aircraft can create weak points or stress concentrations in the structure. Constant use and repeated loading and unloading cycles on the aircraft can lead to fatigue cracking. Additionally, pilot error or adverse weather conditions can cause the aircraft to experience more extreme conditions than those it was designed to tolerate. [1] In some cases, sabotage or terrorism can damage critical systems or components, leading to catastrophic failure.
A range of measures is implemented in aviation to enhance safety and prevent accidents. These measures encompass rigorous design standards, continuous monitoring, and comprehensive training.
An aviation accident is an event during aircraft operation that causes serious injury, death, or destruction. An aviation incident is any operating event that compromises safety but does not progress to an aviation accident. Preventing accidents and incidents is the main goal of aviation safety.
China Airlines Flight 611 was a regularly scheduled passenger flight from Chiang Kai-shek International Airport in Taiwan to Hong Kong International Airport in Hong Kong.
Aloha Airlines Flight 243 was a scheduled Aloha Airlines flight between Hilo and Honolulu in Hawaii. On April 28, 1988, a Boeing 737-297 serving the flight suffered extensive damage after an explosive decompression in flight, caused by part of the fuselage breaking due to poor maintenance and metal fatigue. The plane was able to land safely at Kahului Airport on Maui. The one fatality, flight attendant Clarabelle "C.B." Lansing, was ejected from the airplane. Sixty-five passengers and crew were injured. The substantial damage inflicted by the decompression, the loss of one cabin crew member, and the safe landing of the aircraft established the accident as a significant event in the history of aviation, with far-reaching effects on aviation safety policies and procedures.
Aviation safety is the study and practice of managing risks in aviation. This includes preventing aviation accidents and incidents through research, educating air travel personnel, passengers and the general public, as well as the design of aircraft and aviation infrastructure. The aviation industry is subject to significant regulation and oversight.
Avianca Flight 011 was a Boeing 747-200BM Combi on an international scheduled passenger flight from Frankfurt to Bogotá via Paris, Madrid, and Caracas that crashed near Madrid on 27 November 1983. It took off from Charles de Gaulle Airport in Paris at 22:25 on 26 November 1983 for Madrid Barajas Airport; take-off was delayed waiting for additional passengers from a Lufthansa flight due to a cancellation of the Paris-Frankfurt-Paris segment by Avianca for operational reasons.
An uncontrolled decompression is an undesired drop in the pressure of a sealed system, such as a pressurised aircraft cabin or hyperbaric chamber, that typically results from human error, structural failure, or impact, causing the pressurised vessel to vent into its surroundings or fail to pressurize at all.
Cameroon Airlines was an airline from Cameroon, serving as flag carrier of the country. Based in Douala, it operated scheduled services within Africa, as well as to Europe and the Middle East out of its hub at Douala International Airport, with a second network focus on Yaoundé Nsimalen International Airport. The company was 96.43 percent state-owned, with the remaining shares having been held by Air France. It ceased operations in March 2008; its role as Cameroon's flag carrier was taken over by Camair-Co. The company slogan was French: Pour mieux vous servir, To serve you better.
United Airlines Flight 811 was a regularly scheduled international flight from Los Angeles to Sydney, with intermediate stops at Honolulu and Auckland. On February 24, 1989, the Boeing 747-122 serving the flight experienced a cargo-door failure in flight shortly after leaving Honolulu. The resulting explosive decompression blew out several rows of seats, killing nine passengers. The aircraft returned to Honolulu and landed without further incident.
In aviation, pilot error generally refers to an action or decision made by a pilot that is a substantial contributing factor leading to an aviation accident. It also includes a pilot's failure to make a correct decision or take proper action. Errors are intentional actions that fail to achieve their intended outcomes. The Chicago Convention defines the term "accident" as "an occurrence associated with the operation of an aircraft [...] in which [...] a person is fatally or seriously injured [...] except when the injuries are [...] inflicted by other persons." Hence the definition of "pilot error" does not include deliberate crashing.
The article describes accidents and incidents on Korean Air and its predecessor companies Korean National Airlines and Korean Air Lines.
As of December 2024, a total of 64 Boeing 747 aircraft, or just above 4% of the total number of 747s built, first flown commercially in 1970, have been involved in accidents and incidents resulting in a hull loss, meaning that the aircraft was either destroyed or damaged beyond economical repair. Of the 64 Boeing 747 aircraft losses, 32 resulted in no loss of life; in one, a hostage was murdered; and in one, a terrorist died.
During the 1990s, a series of issues affecting the rudder of Boeing 737 passenger aircraft resulted in multiple incidents. In two separate accidents, pilots lost control of their aircraft due to a sudden and unexpected rudder movement, and the resulting crashes killed everyone on board, 157 people in total. Similar rudder issues led to a temporary loss of control on at least one other Boeing 737 flight before the cause of the problem was ultimately identified.
Air France has been in operation since 1933. Its aircraft have been involved in a number of major accidents and incidents. The deadliest accident of the airline occurred on June 1, 2009, when Air France Flight 447, an Airbus A330-203, flying from Rio de Janeiro to Paris crashed into the Atlantic Ocean with 228 fatalities. A selected list of the most noteworthy of these events is given below.
Asiana Airlines Flight 991 was a cargo flight operated by Asiana Airlines. On 28 July 2011, the Boeing 747-400F flying from Seoul, South Korea, to Shanghai, China, crashed into the sea off Jeju Island after suffering an in-flight cargo fire. Both pilots, the only two people on board, were killed. The accident marked the second loss of a 747 freighter due to a cargo hold fire in less than a year, following the crash of UPS Airlines Flight 6 in Dubai in September 2010.
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.
Southwest Airlines Flight 3472 was a regularly scheduled passenger flight operating from New Orleans International Airport in New Orleans, Louisiana to Orlando International Airport in Orlando, Florida. On August 27, 2016, the Boeing 737-7H4, with 99 passengers and five crew, 12 minutes after departure from New Orleans, was climbing through 31,000 feet and heading east over the Gulf of Mexico when the aircraft's number one CFM International CFM56-7 engine suffered an engine failure. A fan blade in the engine broke due to a fatigue crack. The separated portion of the blade rotated within the engine, moving forward, striking the engine inlet. Debris from the damaged engine inlet punctured the left side of the fuselage causing a loss of cabin pressure and damaged the wing and empennage. Oxygen masks were deployed to passengers while the crew initiated an emergency descent to 10,000 feet. The aircraft then diverted to Pensacola International Airport for a safe landing about 20 minutes later without further incident. While the aircraft sustained substantial damage, there were no injuries.
