Aviation Accident Summary Archive

Avis-Amur Flight 9209, an Antonov An-12AP cargo flight, crashed into mountainous terrain after an in-flight engine fire led to a catastrophic loss of structural integrity and lateral control. The aircraft was carrying 17.43 tonnes of cargo and 11 occupants when a fuel leak in the number one engine nacelle ignited. Despite the crew's attempt to return to Magadan and perform an emergency descent, the fire weakened the left wing structure and damaged aileron control wiring, causing the aircraft to roll uncontrollably into a mountain slope. At the time of the accident, RA-11125 was the oldest aircraft in commercial service in Russia.

In-flight Fire

A U.S. Army CH-47D Chinook, callsign Extortion 17, was shot down by a rocket-propelled grenade (RPG) while attempting to insert a Quick Reaction Force (QRF) in the Tangi Valley. The helicopter was carrying 30 U.S. military personnel, seven Afghan National Army commandos, and one civilian interpreter. The RPG struck the aft rotor assembly as the aircraft approached the landing zone at low altitude, causing an immediate loss of control and a catastrophic crash. All 38 occupants and one military working dog were killed, marking the single deadliest incident for U.S. forces during the war in Afghanistan.

Military Action

Caribbean Airlines Flight 523 overran the runway while landing in rainy weather at Cheddi Jagan International Airport, resulting in the aircraft breaking into two sections. Despite the hull loss, all 163 occupants survived. Seven people were injured in total, with two passengers suffering serious injuries (broken legs). The investigation determined that the flight crew touched down nearly two-thirds of the way down the runway after failing to execute a go-around despite recognizing a poor approach.

Pilot Error

A Boeing 777-266ER suffered a severe cockpit fire while parked at the gate during passenger boarding. The fire originated in the crew's emergency oxygen system storage area on the right side of the cockpit. Although the captain attempted to extinguish the flames, the fire intensified rapidly, fueled by escaping oxygen. All 317 occupants evacuated safely via jet bridges, though seven individuals were treated for smoke inhalation. The aircraft sustained significant structural damage to the forward fuselage and was declared a hull loss.

Mechanical Failure

Asiana Airlines Flight 991, a Boeing 747-400 freighter, crashed into the East China Sea after an uncontained cargo fire led to an in-flight breakup. The aircraft was carrying 58 tonnes of cargo, including lithium batteries and flammable liquids such as paint and photoresist. Approximately 50 minutes after takeoff, the crew reported a fire on the main deck and attempted to divert to Jeju Island. As the fire propagated, the crew reported a loss of flight controls and heavy vibrations before the aircraft disappeared from radar. Both crew members were killed, and the aircraft was destroyed.

In-flight Fire

A Royal Moroccan Air Force C-130H Hercules crashed into Tayyert Mountain while attempting to land at Guelmim Airport during a scheduled stopover. The aircraft was transporting 60 soldiers and approximately 20 others, including crew and civilians (reports vary between 8 crew and 12 civilians, or 9 crew and 11 civilians). Thick fog and poor visibility were reported at the time of the accident. Although three individuals were initially pulled alive from the wreckage, they later succumbed to their injuries, resulting in the deaths of all 80 people on board.

Controlled Flight Into Terrain (CFIT)

Noar Linhas Aereas Flight 4896 crashed shortly after takeoff from Recife following a left engine failure caused by a turbine blade fracture. The aircraft failed to maintain altitude due to a combination of improper rudder application, an overweight takeoff condition, and poor cockpit resource management. Despite the co-pilot's repeated suggestions to perform an emergency landing on the beach, the captain insisted on returning to the airport. The aircraft eventually stalled and crashed into a vacant lot 1,700 meters from the runway, killing all 16 people on board.

Human Factors (CRM)

Angara Airlines Flight 9007 ditched into the Ob River following an uncontained engine fire in the port engine. The fire was initiated by the failure of a compressor rotor support bearing, which led to oil leakage and ignition. The ditching in shallow, uneven water caused the aircraft to break up, resulting in seven fatalities. Investigators determined that the fire became inextinguishable because the crew delayed shutting down the engine after the initial fire alarm and abnormal indications.

Human Factors (Maintenance)

Hewa Bora Airways Flight 952 crashed into a wooded area while attempting to land at Kisangani during a severe thunderstorm. The aircraft impacted terrain approximately 1,000 meters short of the runway threshold after the crew discontinued an approach to runway 13 and attempted a visual approach to runway 31 in poor visibility. The investigation revealed significant regulatory and operational failures, including the use of unlicensed flight crew and air traffic controllers, as well as the provision of erroneous weather data to the pilots.

Controlled Flight Into Terrain (CFIT)

A Cessna 208B Grand Caravan overran the runway and crashed into a ravine following a rejected takeoff from a soft, gravel-surfaced runway. The aircraft failed to accelerate to liftoff speed due to a combination of soft runway patches, gusty wind conditions, and a takeoff technique that increased aerodynamic drag. Although the pilot initiated a rejected takeoff, the decision was made with only 600 feet of runway remaining, which was insufficient to stop the aircraft before it reached a steep 20-foot drop-off. A post-impact fire broke out almost immediately, leading to the death of one passenger who was unable to evacuate.

Pilot Error

RusAir Flight 9605 crashed during a night approach in heavy fog after the crew descended below the minimum safe altitude without visual contact with the runway. The investigation revealed a severe breakdown in crew resource management, exacerbated by the navigator's alcohol intoxication. The crew relied on an unapproved GPS unit for the approach while ignoring standard radio navigation aids, leading to a significant lateral deviation. The aircraft struck trees and impacted a highway approximately 570 meters short of the runway threshold.

Pilot Error

A Boeing 707 tanker aircraft suffered a catastrophic engine separation during its takeoff roll, leading to a runway excursion and a massive post-impact fire. At an altitude of approximately 20 feet above ground level and 7,000 feet down the runway, the No. 2 engine detached from the wing due to the fatigue failure of a midspar fitting. The departing engine struck the No. 1 engine's inlet cowling, causing significant drag and a loss of thrust on the left side. Despite the crew's attempts to maintain control, the aircraft drifted off the runway and came to rest in a saltwater marsh. All three crew members evacuated with injuries before the aircraft was consumed by fire.

Human Factors (Maintenance)

Sol Líneas Aéreas Flight 5428 crashed in a remote region of Patagonia after encountering severe icing conditions that led to an aerodynamic stall and loss of control. The aircraft, a Saab 340A, was operating the final leg of a multi-stop domestic route when it entered an area of severe icing that overwhelmed its de-icing systems. The investigation determined that the flight crew failed to maintain adequate airspeed and applied inappropriate recovery techniques when the aircraft stalled. All 22 people on board were killed when the aircraft impacted the ground at night.

Pilot Error

Merpati Nusantara Flight 8968 crashed into the sea during a failed visual approach to Utarom Airport in Kaimana, West Papua. The aircraft impacted the water approximately 800 meters southwest of the runway threshold after the crew attempted a go-around in poor visibility. The investigation determined that the pilots attempted a visual approach in weather conditions that mandated instrument procedures, then lost control during the missed approach due to improper flap retraction and excessive bank angles. All 25 people on board were killed.

Pilot Error

A Pawan Hans Mil Mi-172 helicopter crashed and burst into flames while attempting to land at the high-altitude Tawang Civil Helipad. During the final approach, the helicopter descended below the helipad's elevation, causing the left undercarriage to strike the concrete edge of the landing site. The impact caused the aircraft to topple into a steep gorge, where it was destroyed by a post-crash fire. The investigation determined the helicopter was operating above its maximum stipulated weight and the crew had disregarded local meteorological data.

Pilot Error

On April 4, 2011, a Georgian Airways Bombardier CRJ-100ER, operating a United Nations charter flight, crashed during a go-around at N'Djili International Airport in Kinshasa. The aircraft encountered a severe microburst associated with a fast-moving squall line, causing it to pitch down violently and impact the ground at a very low altitude. Of the 33 people on board, including 29 passengers and 4 crew members, only one passenger survived with serious injuries. The investigation cited the crew's decision to continue the approach into known severe weather and systemic failures in pilot training and regulatory oversight as major contributing factors.

Weather

Southwest Airlines Flight 812 experienced a rapid decompression at 34,400 feet when a 60-inch section of the fuselage crown skin ruptured and peeled back. The flight crew performed an emergency descent and diverted to Yuma International Airport, where the aircraft landed safely. The investigation identified a manufacturing error at a lap joint that led to multiple site fatigue cracking. While all 122 occupants survived, official NTSB statistics record one minor injury (a flight attendant who suffered a broken nose), though narrative reports also note a minor head injury sustained by an off-duty airline employee who lost consciousness during the decompression.

Mechanical Failure

A Trans Air Congo Antonov An-12BP cargo aircraft crashed into the densely populated Mvoumvou residential district while on final approach to Pointe-Noire, killing all 4 crew members and 19 people on the ground for a total of 23 fatalities. The aircraft suffered a dual engine failure on the right wing (engines No. 3 and No. 4) at low altitude. As the crew applied maximum power to the remaining left-side engines to realign with the runway, the asymmetric thrust exceeded the aircraft's rudder authority at low airspeed, causing the aircraft to roll inverted and dive into houses. The aircraft had been listed as non-airworthy by ICAO since 2006.

Mechanical Failure

An Antonov An-148-100E undergoing a pre-delivery demonstration and training flight suffered an in-flight structural failure after the crew inadvertently exceeded the aircraft's maximum design speed by 110 km/h. During an emergency descent maneuver, the aircraft entered a state of low-frequency oscillations that led to the breakup of the airframe. All six people on board, including two Myanmar Air Force representatives and four Russian crew members, were killed when the wreckage fell near the village of Garbuzovo.

Pilot Error

Central American Airways Flight 731 was a scheduled domestic flight that resulted in a Controlled Flight Into Terrain (CFIT) accident near Santa Ana, Honduras, killing all 14 people on board. The aircraft stalled while configured with full flaps during its second approach attempt to Toncontín International Airport. Investigators determined that the crew failed to follow published approach procedures, exhibited poor crew resource management, and operated at speeds only slightly above stall speed in an area known for wind shear and mountain waves. The crash claimed the lives of several high-ranking Honduran government officials, leading to three days of national mourning.

Human Factors (Operational)

A Fairchild Metro III crashed and overturned while attempting a third approach in heavy fog at Cork Airport, killing both pilots and four passengers. The investigation revealed a catastrophic breakdown in operational oversight, involving a complex web of leasing agreements that left the crew poorly trained, fatigued, and unsupervised. During the final approach, the commander took control of the power levers while the co-pilot flew the aircraft, leading to uncoordinated inputs. When a go-around was initiated below the decision height, the commander retarded the power levers into the prohibited 'Beta' range, causing a massive power asymmetry and a rapid roll that inverted the aircraft upon impact with the runway.

Pilot Error

Iran Air Flight 277 crashed during a missed approach in heavy snow and icing conditions near Urmia Airport. After failing to land on the first attempt due to poor visibility, the crew initiated a go-around. During this maneuver, the aircraft experienced a double engine flame-out caused by severe icing and improper engine management. The crew was unable to maintain altitude or restart the engines in time, leading to an impact with terrain 15 kilometers from the airport.

Pilot Error

On January 1, 2011, a Kolavia Tupolev Tu-154B-2 caught fire during taxiing at Surgut International Airport. As the crew connected the generators to the electrical network following engine start, an electrical arc developed in a contactor panel located in the center section of the fuselage. The fire spread rapidly through the passenger cabin, leading to an emergency evacuation via slides. While most occupants escaped, three passengers were killed and 43 were injured, primarily due to smoke inhalation and burns. The aircraft was completely destroyed by the blaze within 40 minutes.

Mechanical Failure

A Tara Air DHC-6 Twin Otter crashed into Palunge Hill shortly after departing Lamidanda Airport, killing all 22 people on board. The aircraft was operating a scheduled domestic flight to Kathmandu when it encountered deteriorating weather and thick haze. The investigation determined that the crew made an unwise decision to descend into mountainous terrain while in Instrument Meteorological Conditions (IMC) without adequate consideration for the surrounding topography, resulting in a Controlled Flight Into Terrain (CFIT).
