# Aviation accidents and incidents

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.
One of the earliest recorded aviation accidents occurred on May 10, 1785, when a hot air balloon crashed in the town of Tullamore, County Offaly, Ireland. The town was seriously damaged from the resultant fire that burned down over 130 homes. The first involving a powered aircraft was the crash of a Wright Model A aircraft at Fort Myer, Virginia, in the United States on September 17, 1908, injuring its co-inventor and pilot, Orville Wright, and killing the passenger, Signal Corps lieutenant Thomas Selfridge.

## Definitions

The Convention on International Civil Aviation Annex 13 formally defines an aviation accident as an occurrence associated with the operation of an aircraft, which takes place from the time any person boards the aircraft with the intention of flight until all such persons have disembarked, and in which (a) a person is fatally or seriously injured, (b) the aircraft sustains significant damage or structural failure, or (c) the aircraft goes missing or becomes completely inaccessible. Annex 13 defines an aviation incident as an occurrence, other than an accident, associated with the operation of an aircraft that affects or could affect the safety of operation.
A hull loss occurs if an aircraft is damaged beyond repair, is lost, or becomes completely inaccessible.

## History

The first aircraft accident in which 200 or more people died occurred on March 3, 1974, when 346 died in the crash of Turkish Airlines Flight 981. As of May 2024, there have been a total of 33 aviation incidents in which 200 or more people have died.
The period from 1958 to 1968 saw tremendous growth in aviation. Improvements in aviation safety and accident investigation procedures were rapidly advancing. In 1963, the Civil Aeronautics Board, under the leadership of then Deputy Director Bobbie R. Allen, established the National Aircraft Accident Investigation School in Oklahoma City.
The ICAO's third accident investigation division meeting, held in Montreal, Canada, in January 1965, laid the foundation for accident investigations throughout the world. The proposals were presented by the Director of the Civil Aeronautics Board Bureau of Safety, Bobbie R. Allen, who headed the U.S. delegation. The U.S. formally adopted the proposals at the White House on December 1, 1965.
The top 10 countries with the highest number of fatal civil airliner accidents from 1945 to 2021 are the United States, Russia, Canada, Brazil, Colombia, United Kingdom, France, Indonesia, Mexico, and India. The United Kingdom is noted to have the highest number of air crashes in Europe, with a total of 110 air crashes within the time period, and Indonesia is the highest in Asia at 104, followed by India at 95.
The most fatalities on board a single aircraft are the 520 fatalities of the 1985 Japan Air Lines Flight 123 accident. The largest loss of life in a single aviation accident are the 583 fatalities of the 1977 Tenerife airport disaster, in which two Boeing 747s collided. The largest loss of life overall in a collective incident are the 2,996 fatalities in the coordinated terrorist destruction of airplanes and occupied buildings in the 2001 September 11 attacks, the first plane to be hijacked and crashed as part of the attack, American Airlines Flight 11, was alone responsible for an estimated 1,700 fatalities in total, making it the single deadliest aviation disaster in history.

### September 11 attacks

2,996: The deadliest aviation-related disaster regarding fatalities both on board the aircraft and casualties on the ground, was the destruction of the World Trade Center in New York City on September 11, 2001. On that morning, four commercial jet airliners traveling on transcontinental flights from East Coast airports to California were hijacked after takeoff. The four hijacked aircraft were subsequently crashed in a series of four coordinated suicide attacks against major American landmarks by 19 Islamist terrorists affiliated with Al-Qaeda. American Airlines Flight 11 and United Airlines Flight 175, both regularly scheduled domestic transcontinental flights from Boston to Los Angeles, were hijacked by five men each, with the assigned pilot hijacker taking control of the flight, before being intentionally crashed into the North and South Towers of the World Trade Center, respectively, destroying both buildings in less than two hours. The World Trade Center crashes killed 2,753. As both planes were carrying a combined total of 157 occupants, the vast majority of fatalities were the occupants of the two towers and the emergency personnel responding to the disaster. In addition, 184 were killed by the impact of American Airlines Flight 77, which crashed into the Pentagon in Arlington County, Virginia, causing severe damage and partial destruction to the building's west side. The crash of United Airlines Flight 93 into a field in Somerset County, Pennsylvania, which occurred as passengers attempted to retake control of the aircraft from the hijackers, killed all 40 passengers and crew aboard the aircraft. This brought the total number of casualties of the September 11 attacks to 2,996 (including the 19 terrorist hijackers). As deliberate terrorist acts, the 9/11 crashes were not classified as accidents, but as mass-killing. The events were treated by the member nations of NATO as an act of war and terrorism. The war on terror was subsequently launched by NATO in response to the attacks, eventually leading to the death of Al-Qaeda leader Osama Bin Laden, who orchestrated the 9/11 attacks.

### Tenerife disaster

583: The Tenerife airport disaster on March 27, 1977, remains the accident with the highest number of airliner passenger fatalities. 583 people died when a KLM Boeing 747 attempted to take off and collided with a taxiing Pan Am 747 at Los Rodeos Airport on the Canary Island of Tenerife, Spain. All 234 passengers and 14 crew of the KLM aircraft died and 335 of the 396 passengers and crew of the Pan Am aircraft died. Pilot error was the primary cause, as the KLM captain began his takeoff run in the mistaken belief he had obtained air traffic control clearance. Other contributing factors were a terrorist incident at Gran Canaria Airport that had caused many flights to be diverted to Los Rodeos, a small airport not well equipped to handle aircraft of such size, dense fog, poor radio phraseology, and controller distraction. The KLM flight crew could not see the Pan Am aircraft on the runway until immediately before the collision. The accident had a lasting influence on the industry, particularly in the area of communication. An increased emphasis was placed on using standardized phraseology in air traffic control (ATC) communication by both controllers and pilots alike. "Cockpit Resource Management" has also been incorporated into flight crew training. The captain is no longer considered infallible, and combined crew input is encouraged during aircraft operations.

### Japan Air Lines Flight 123

520: The crash of Japan Air Lines Flight 123 on August 12, 1985, has the highest number of fatalities for any single-aircraft accident: 520 people died aboard a Boeing 747. The aircraft suffered an explosive decompression from an incorrectly repaired aft pressure bulkhead, which failed in mid-flight, destroying most of its vertical stabilizer and severing all of the hydraulic lines, making the 747 virtually uncontrollable. Pilots were able to keep the plane flying for 32 minutes after the mechanical failure before crashing into a mountain. All 15 crew members and 505 of the 509 passengers aboard died. Japanese military personnel inaccurately assumed, during a helicopter flyover of the impact site, that there were no survivors. Rescue operations were delayed until the following morning. Medical providers involved in rescue and analysis operations determined that several passengers likely survived the impact and probably would have survived the incident had rescue operations not been delayed. Four passengers survived the incident in its entirety, meaning that they were alive when discharged from the hospital.

### Other crashes with death tolls of 200 or more

349: On November 12, 1996, Saudia Flight 763, operated by a Boeing 747, and Kazakhstan Airlines Flight 1907, operated by a Russian Ilyushin Il-76, collided mid-air over the town of Charkhi Dadri, near Delhi, India. The collision was mainly the result of the Kazakh pilot flying lower than the assigned clearance altitude. All 349 occupants on-board the two aircraft died. It remains the world's deadliest mid-air collision without survivors. The Ramesh Chandra Lahoti Commission, empowered to study the causes, recommended the creation of the "semi-circular rule", to prevent aircraft from flying in opposite directions at the same altitude. The Civil Aviation Authorities in India made it mandatory for all aircraft flying in and out of India to be equipped with a Traffic Collision Avoidance System (TCAS), setting a worldwide precedent for mandatory use of TCAS.
346: On March 3, 1974, Turkish Airlines Flight 981, a McDonnell Douglas DC-10, crashed in a forest northeast of Paris, France. The London-bound aircraft crashed shortly after taking off from Orly airport; all 346 people aboard died. It was later determined that the cargo door detached, which caused an explosive decompression; this caused the floor just above to collapse. The collapsed floor severed the control cables, which left the pilots without control of the elevators, the rudder and No. 2 engine. The aircraft entered a steep dive and crashed. It was the deadliest plane crash of all time until the Tenerife disaster in 1977. However, it is currently the deadliest single-aircraft crash with no survivors. This accident was also the deadliest single-aircraft crash that did not involve a Boeing 747.
329: On June 23, 1985, Air India Flight 182, a Boeing 747-237B en route from Toronto and Montreal to London and Delhi, crashed off the southwest coast of Ireland when a bomb exploded in the cargo hold. All 307 passengers and 22 crew members died. One passenger had checked in as "M. Singh". Singh did not board the flight but his suitcase, containing the bomb, was loaded onto the aircraft. "M. Singh" was never identified or captured. It was later determined Sikh extremists were behind the bombing as a retaliation for the Indian government's attack on the Golden Temple in the city of Amritsar, spiritually the most significant shrine in Sikhism. This was, at the time, the deadliest terrorist attack involving an airplane.
301: On August 19, 1980, Saudi Arabian Airlines Flight 163, a Lockheed L-1011, became the world's deadliest aviation accident that did not involve a crash. The crew performed an emergency landing at Riyadh after a fire broke out in an aft baggage compartment. The fire burned through the ceiling of the compartment and into the passenger cabin. While the crew managed to land the aircraft safely, the captain did not stop immediately and order an evacuation. He taxied off the runway instead, by which time everyone in the cabin had become unconscious due to fumes and were unable to open any doors or evacuate. All 301 passengers and crew aboard died of suffocation before rescue ground crews could open any door, after which the aircraft burst into flames and was consumed by fire.
298: On July 17, 2014, Malaysia Airlines Flight 17, a Boeing 777-200ER, flying from Amsterdam to Kuala Lumpur, was shot down in an area of Eastern Ukraine near the Ukraine/Russian border during the war in Donbas. There were 298 people on board: 283 passengers and 15 crew members, all of whom died. The crew were all Malaysians, while the passengers were of various nationalities, most from the Netherlands. Several Ukrainian Air Force (UAF) aircraft had been shot down over the rebel-controlled territory before the MH17 incident. Immediately after the crash, a post appeared on the VKontakte social media profile attributed to Igor Girkin, leader of the Donbas separatist militia, claiming responsibility for shooting down a Ukrainian An-26 military transport near Torez. The post was removed later the same day, and the separatists then denied shooting down any aircraft.
290: On July 3, 1988, Iran Air Flight 655, an Iranian civilian Airbus A300-200 airliner, was shot down by two surface-to-air missiles from the U.S. Navy guided missile cruiser USS Vincennes over the Strait of Hormuz. All 290 passengers and crew aboard the aircraft died. The downing was caused by a series of mistakes that led the USS Vincennes crew to believe that the airliner was an Iranian Air Force F-14.
275: On February 19, 2003, an Iranian military Ilyushin Il-76 crashed in mountainous terrain near Kerman in Iran. The official report says bad weather brought the aircraft down; high winds and fog were present at the time of the crash.
273: On May 25, 1979, American Airlines Flight 191, a McDonnell Douglas DC-10-10, crashed shortly after lifting off the runway at Chicago O'Hare Airport after the number one (left) engine and pylon separated from the wing. This broke hydraulic lines, causing leading edge lift devices to retract on that side of the aircraft and resulted in asymmetrical lift and loss of control. The accident was attributed to improper maintenance procedures. The crash resulted in the deaths of all 271 passengers and crew on board, as well as two people on the ground. It remains the deadliest commercial aircraft accident in United States history, and was also the country's deadliest aviation disaster until the September 11 attacks in 2001.
270: On December 21, 1988, Pan Am Flight 103, a Boeing 747-121 bound for New York–JFK from London–Heathrow with continued service to Detroit, was destroyed by a terrorist bomb over the town of Lockerbie, Scotland. All 259 occupants and 11 people on the ground (all residents of Sherwood Crescent, Lockerbie), died, making it the worst terrorist attack involving an aircraft in the UK and the deadliest terrorist attack on British soil. Following the crash, the Federal Aviation Administration imposed new security measures on American airlines flying out of 103 airports in Western Europe and the Middle East.
269: On September 1, 1983, a Soviet interceptor Sukhoi Su-15 shot down Korean Air Lines Flight 007, a Boeing 747-230B, bound for Gimpo International Airport in Seoul, South Korea, after it flew into Soviet airspace; all 269 occupants on board died.
265: On November 12, 2001, American Airlines Flight 587, an Airbus A300, crashed in the Belle Harbor neighborhood of Queens, New York, just after departing John F. Kennedy International Airport bound for Las Américas International Airport, Santo Domingo. The first officer's overuse of the rudder in response to wake turbulence from a Japan Airlines 747 was cited as cause. All 260 people on board, as well as five people on the ground, died from the crash. It is the second-deadliest aviation accident on U.S. soil, after American Airlines Flight 191.
264: On April 26, 1994, China Airlines Flight 140 was completing a routine flight and approach at Nagoya Airport, Japan, when the Airbus A300B4-622R's First Officer inadvertently pressed the takeoff/go-around button, which raises the throttle position to the same as that for take offs and go-arounds. The action and the two pilots' reaction resulted in a crash that killed 264 (15 crew and 249 passengers) of the 271 people aboard.
261: On July 11, 1991, Nigeria Airways Flight 2120, a Douglas DC-8-61 aircraft operated by Nationair Canada, crashed in Jeddah, Saudi Arabia, after two tires ignited upon takeoff, leading to an in-flight fire. All 261 occupants were killed. It is the deadliest aviation accident involving a DC-8, the largest aviation disaster involving a Canadian-registered aircraft and the second-worst accident in Saudi Arabia (after Saudi Arabian Airlines Flight 163 – see above).
257: On April 11, 2018, an Algerian Air Force transport aircraft crashed shortly after take-off from Boufarik Airport, killing all 257 occupants on board the Ilyushin Il-76.
257: On November 28, 1979, Air New Zealand Flight 901, an Antarctic sightseeing flight, collided with Mount Erebus on Ross Island, Antarctica, killing all 257 occupants on board. The flight crew had not been informed that the computer coordinates for the flight path of the McDonnell Douglas DC-10-30 had been changed the night before, directing the flight directly into Mount Erebus rather than the usual path down McMurdo Sound.
256: On December 12, 1985, a Douglas DC-8, Arrow Air Flight 1285R, carrying American military personnel on a charter flight home for Christmas, crashed in Newfoundland; all 256 occupants on board died. The Canadian Aviation Safety Board investigating the cause of the crash issued two different reports: the majority report cited ice on the wings as cause of the crash; the minority report suggests an explosion was the likely cause. This has been the deadliest aviation incident in Canadian history.
239: On March 8, 2014, a Boeing 777-200ER, Malaysia Airlines Flight 370, flying from Kuala Lumpur, Malaysia, to Beijing, China, lost contact with air traffic controllers over the South China Sea, deviated from its planned route, and was presumed lost in the southern Indian Ocean. It carried 12 Malaysian crew members and 227 passengers from 15 nations, who are all presumed dead. A multinational search effort, the most extensive and expensive in aviation history, has thus far failed to locate the aircraft, though debris from the aircraft has been recovered from beaches around the Indian Ocean. Numerous theories have been offered to explain the disappearance of the flight, but none have been confirmed.
234: On September 26, 1997, an Airbus A300B4-220, Garuda Indonesia Flight 152, which departed from Jakarta, Indonesia, and was preparing to land at Medan, North Sumatra, crashed into mountainous terrain, killing all 234 occupants on board. The causes included turning left instead of right as instructed by ATC and descending below the assigned altitude of 2,000 feet due to pilot error. It is the deadliest aviation disaster in Indonesia's history.
230: On July 17, 1996, a Boeing 747-131, TWA Flight 800, carrying 230 occupants, exploded and crashed into the Atlantic Ocean near East Moriches, New York, shortly after departing from John F. Kennedy International Airport on a flight to Paris and Rome. A lengthy investigation concluded that the probable cause of the accident was a short circuit in a fuel tank that contained an explosive mixture of fuel vapor and air. As a result, new requirements were developed to prevent future fuel tank explosions in aircraft.
229: On September 2, 1998, a McDonnell Douglas MD-11, Swissair Flight 111, carrying 215 passengers and 14 crew from New York City to Geneva, Switzerland, crashed into the Atlantic Ocean near Halifax, Nova Scotia, Canada, killing all 229 people aboard. After a lengthy investigation, an official report stated that flammable material used in the aircraft's structure, specifically the Personal TV Systems recently installed in the Business Class Cabin, allowed a fire to spread, resulting in a loss of control.
228: On June 1, 2009, an Airbus A330-203, Air France Flight 447, carrying 228 occupants, was en route from Rio de Janeiro, Brazil to Paris, France, when it crashed into the Atlantic Ocean. The aircraft's flight recorders were not recovered from the ocean floor until May 2011, and the final investigative report was released in July 2012. It determined that the disaster was likely due to the aircraft's pitot tubes being obstructed by ice crystals, causing the autopilot to disconnect. The crew reacted incorrectly, leading to an aerodynamic stall from which the jet did not recover.
228: On August 6, 1997, a Boeing 747-3B5, Korean Air Flight 801, crashed on approach to the international airport in the United States territory of Guam, killing 228 of the 254 people aboard. Contributing factors in the crash were fatigue and errors by the flight crew, inadequate flight crew training, and a modification of the airport's altitude warning system that prevented it from detecting aircraft below a minimum safe altitude.
227: On January 8, 1996, an Antonov An-32B aircraft with six crew members on board overshot the runway at N'Dolo Airport, Kinshasa, Democratic Republic of Congo, and crashed into a market place. Four on board survived but 225 people on the ground were killed and an estimated 500 were injured (estimated 253 seriously injured). It is the crash with the most non-passenger ground fatalities (not including 9/11). It is usually known as the 1996 Air Africa crash.
225: On May 25, 2002, a Boeing 747-209B, China Airlines Flight 611, bound for Hong Kong International Airport in Hong Kong, disintegrated in mid-air and crashed into the Taiwan Strait 20 minutes after takeoff from Chiang Kai-shek International Airport (now Taiwan Taoyuan International Airport) in Taiwan. It was determined that the crash, which killed all 206 passengers and 19 crew members aboard the plane, was caused by improper repairs to the aircraft 22 years earlier when the aircraft encountered a tailstrike.
224: On October 31, 2015, an Airbus A321-231, Metrojet Flight 9268, crashed in the Sinai Peninsula after departing Sharm el-Sheikh International Airport, Egypt, en route to Pulkovo Airport, Saint Petersburg, Russia. All 224 occupants on board were killed. A branch of the Islamic State of Iraq and the Levant claimed responsibility for bringing down the jet, and a Russian investigation concluded that a bomb was detonated inside the plane at a high altitude.
223: On May 26, 1991, a Boeing 767-3Z9ER, Lauda Air Flight 004, broke up in midair over a remote area of Thailand due to an uncommanded deployment of a thrust reverser on one of the plane's engines, killing all 223 occupants aboard. The flight, which originated at Kai Tak Airport, Hong Kong, and made a stopover at Don Mueang International Airport in Bangkok, Thailand, was en route to Vienna International Airport, Vienna, Austria, when the accident occurred.
217: On October 31, 1999, a Boeing 767-366ER, EgyptAir Flight 990, flying from Los Angeles International Airport, United States, to Cairo International Airport, Egypt, with a stop at John F. Kennedy International Airport, New York City, crashed into the Atlantic Ocean south of Nantucket Island, Massachusetts, killing all 217 occupants onboard. The National Transportation Safety Board determined that the probable cause of the crash was deliberate action by the relief first officer in response to his removal from international service within Egyptair, a finding disputed by Egyptian authorities who maintain another cause of the accident.
213: On January 1, 1978, a Boeing 747-237B, Air India Flight 855, crashed into the Arabian Sea just off the coast of Bombay, India, killing all 213 occupants on board. An investigation concluded that the captain became disoriented after the failure of one of the flight instruments in the cockpit, leading to "irrational control inputs" that caused the plane to crash.
202: On February 16, 1998, an Airbus A300B4-622R, China Airlines Flight 676, en route from Ngurah Rai Airport in Bali, Indonesia, to Chiang Kai-shek International Airport (now Taoyuan International Airport), Taiwan, crashed into a road and residential neighborhood in Taoyuan, Taiwan, killing 182 passengers, 14 crew, and six people on the ground. An investigation determined that when the control tower ordered the pilot to abort his landing and "go around" for a second attempt, the pilot, who had unintentionally released the plane's autopilot, did nothing to take control of the plane for 11 seconds as he apparently thought the autopilot would initiate the go around. As the aircraft approached the airport, the pilot executed a sudden steep ascent that produced a stall and crash. China Airlines was also criticized for "insufficient training".
200: On July 10, 1985, a Tupolev Tu-154B-2, Aeroflot Flight 7425, on a domestic Karshi–Ufa–Leningrad route, crashed near Uchkuduk, Uzbek SSR, Soviet Union, on the first leg of its route. All 200 occupants onboard were killed. An investigation concluded that the plane went down due to pilot error. The air crew used an inappropriately low airspeed, causing vibrations that they incorrectly interpreted as engine surges. As a result, they further reduced engine power, causing the aircraft to stall and crash.

## Safety

In over one hundred years of implementation, aviation safety has improved considerably. In modern times, two major manufacturers still produce heavy passenger aircraft for the civilian market: Boeing in the United States, and the European company Airbus. Both of these manufacturers place a huge emphasis on the use of aviation safety equipment, now a billion-dollar industry in its own right; safety is a key selling point for these companies, as they recognize that a poor safety record in the aviation industry is a threat to corporate survival.
Some major safety devices now required in commercial aircraft are:
* Evacuation slides, to aid rapid passenger exit from an aircraft in an emergency situation
* Advanced avionics, incorporating computerized auto-recovery and alert systems
* Turbine engines with improved durability and failure containment mechanisms
* Landing gear that can be lowered even after loss of power and hydraulics
Measured on a passenger-distance calculation, air travel is the safest form of transportation available: Figures mentioned are the ones shared by the air industry when quoting air safety statistics. A typical statement, e.g., by the BBC: "UK airline operations are among the safest anywhere. When compared against all other modes of transport on a fatality per mile basis, air transport is the safest – six times safer than travelling by car and twice as safe as rail."
When measured by fatalities per person transported, however, buses are the safest form of transportation. The number of air travel fatalities per person are surpassed only by bicycles and motorcycles. This statistic is used by the insurance industry when calculating insurance rates for air travel.
For every billion kilometers traveled, trains have a fatality rate that is 12 times higher than that of air travel, and the fatality rate for automobiles is 62 times greater than for air travel. By contrast, for every billion journeys taken, buses are the safest form of transportation; using this measure, air travel is three times more dangerous than car transportation, and almost 30 times more dangerous than travelling by bus.
A 2007 study by Popular Mechanics magazine found that passengers sitting at the back of an aeroplane are 40% more likely to survive a crash than those sitting at the front. The article quotes Boeing, the FAA, and a website on aircraft safety, all of which claim that there is no "safest" seat. The study examined 20 crashes, not taking into account the developments in safety after those accidents. However, a flight data recorder is usually mounted in the aircraft's empennage (tail section) where it is more likely to survive a severe crash.
Between 1983 and 2000, the survival rate for people in U.S. plane crashes was greater than 95 percent.

### Global Aeronautical Distress and Safety System

In an effort to prevent incidents such as the disappearance of Malaysia Airlines Flight MH370, a new standard has been issued requiring all commercial aircraft to report their position every 15 minutes to air traffic controllers regardless of the country of origin. Introduced in 2016 by the ICAO, the regulation has no initial requirement for any new aircraft equipment to be fitted. The standard is part of a long-term plan, called the Global Aeronautical Distress and Safety System (GADSS), which will require new aircraft to be equipped with data broadcast systems that are in constant contact with air traffic controllers. The GADSS is similar to the Global Maritime Distress and Safety System (GMDSS) used for maritime safety.

### Aviation Safety Reporting System

The Aviation Safety Reporting System (ASRS) collects voluntarily submitted aviation safety incident/situation reports from pilots, controllers and others. The ASRS uses reports to identify system deficiencies, issue alert messages, and produce two publications, CALLBACK, and ASRS Directline. The collected information is made available to the public, and is used by the FAA, NASA and other organizations working in research and flight safety.

## Statistics
### Bureau of Aircraft Accidents Archives (B3A)

The Bureau of Aircraft Accidents Archives (B3A), formerly known as the Aircraft Crashes Record Office (ACRO), a non-government organization based in Geneva, Switzerland, compiles statistics on aviation accidents of aircraft capable of carrying more than six passengers, excluding helicopters, balloons, and combat aircraft. ACRO only considers crashes in which the aircraft has suffered such damage that it is removed from service, which will further reduce the statistics for incidents and fatalities compared to some other data. The total fatalities due to aviation accidents since 1970 are 83,772. The total number of incidents are 11,164.
According to ACRO, recent years have been considerably safer for aviation, with fewer than 170 incidents every year between 2009 and 2017, compared to as many as 226 as recently as 1998.
The annual fatalities figure is less than 1,000 for ten of the fourteen years between 2007 and 2020, the year 2017 experiencing the lowest number of fatalities, at 399, since the end of World War II.
2014 included the disappearance of flight MH370 over the Indian Ocean and the shootdown of flight MH17 as part of the war in Donbas. The total number of fatalities in 2014 was 869 more than in 2013.
Deaths and incidents in the world per year according to ACRO and Bureau of Aircraft Accident Archives data, as of January 1, 2019:

### Annual Aviation Safety Review (EASA)

The European Aviation Safety Agency (EASA) is tasked by Article 15(4) of Regulation (EC) No 216/2008 of the European Parliament and of the Council of February 20, 2008, to provide an annual review of aviation safety.
The Annual Safety Review presents statistics on European and worldwide civil aviation safety. Statistics are grouped according to type of operation, for instance, commercial air transport, and aircraft category, such as aeroplanes, helicopters, gliders, etc. The Agency has access to accident and statistical information collected by the International Civil Aviation Organization (ICAO). States are required, according to ICAO Annex 13, on Aircraft Accident and Incident Investigation, to report to ICAO information, on accidents and serious incidents to aircraft with a maximum certificated take-off mass (MTOM) over 2250 kg. Therefore, most statistics in this review concern aircraft above this mass. In addition to the ICAO data, a request was made to the EASA Member States to obtain light aircraft accident data. Furthermore, data on the operation of aircraft for commercial air transport were obtained from both ICAO and the NLR Air Transport Safety Institute.

## Investigation

The NTSB also investigates overseas incidents involving US-registered aircraft, in collaboration with local investigative authorities, especially when significant loss of American lives occurs, or when the involved aircraft is American-built.

## Retirement of flight numbers

Out of respect for the deceased and injured, it is common for an airline to cease using the flight number of a fatal crash. For example, following the shootdown of Malaysia Airlines Flight 17, the flight number was changed to MH19. Japan Airlines stopped using the flight number 350 after a fatal plane crash in Tokyo Bay. TransAsia Airways retired the flight number 235 and changed it to 2353 after a plane crash in 2015 that left 15 survivors. However, that is not always the case. For example, China Southern Airlines and FedEx Express continued using the flight number 3456 and 14 respectively even after China Southern Airlines had a fatal accident in 1997 and a FedEx Express aircraft crashed on landing a month later. Similarly, Japan Airlines and Singapore Airlines continued using the flight number 516 and 321 respectively, even after the Japan Airlines flight was involved in a collision in 2024 while the Singapore Airlines flight encountered severe turbulence and caused one death a few months later.
