Aviation Accident Summary Archive

A Tajikistan Airlines Yakovlev Yak-40 crashed during takeoff after being hijacked by militants who forced the crew to board 81 passengers, nearly triple the aircraft's capacity. The resulting 3,000 kg overload prevented the aircraft from becoming airborne, leading to a high-speed runway overrun into the Panj River.

Security / Sabotage

A McDonnell Douglas DC-8 cargo flight stalled and crashed during a steep, poorly executed turn to final approach at Guantánamo Bay. Despite the aircraft being destroyed by impact and a post-crash fire, all three crew members survived the cockpit's separation from the fuselage. The investigation highlighted this as the first major accident where pilot fatigue was cited as a primary probable cause, as the crew had been awake for nearly 24 hours and were operating under a regulatory loophole that extended their duty limits.

Human Factors (Operational)

On 12 August 1993, a Royal Air Force Westland Wessex HC2 helicopter crashed into Llyn Padarn after suffering a catastrophic tail rotor drive failure. The aircraft was conducting a search and rescue training mission with three crew members and four Air Training Corps cadets on board. During a simulated autopilot failure, the tail rotor drive shaft disconnected and then re-engaged, causing a shock load that fractured the shaft. The helicopter became uncontrollable, spun, and plunged into the lake, sinking rapidly. While all three crew members and one cadet escaped with major injuries, the remaining three cadets were unable to egress and drowned.

Mechanical Failure

On July 31, 1993, an Everest Air Dornier 228 crashed into a mountain slope during an approach to Bharatpur Airport, killing all 19 people on board. The aircraft was operating a scheduled domestic flight from Kathmandu. The investigation determined the accident was a Controlled Flight Into Terrain (CFIT) occurring in poor visibility and bad weather. A critical factor was the unavailability of the Bharatpur Non-Directional Beacon (NDB), which had been disabled by recent heavy flooding, depriving the crew of a primary navigational aid during the approach.

Controlled Flight Into Terrain (CFIT)

Asiana Airlines Flight 733 crashed into a ridge on Mount Ungeo during its third attempt to land at Mokpo Airport in heavy rain and high winds. The Boeing 737-500 descended below the minimum safe altitude during a non-precision VOR/DME approach, striking terrain at approximately 800 feet. The investigation cited pilot error, specifically the captain's decision to continue the approach below visibility minimums and failure to adhere to prescribed approach altitudes.

Controlled Flight Into Terrain (CFIT)

Merpati Nusantara Airlines Flight 724 crashed into a hill and subsequently the sea while attempting to land at Jefman Airport during a severe thunderstorm. The pilot, reportedly disoriented by inclement weather, ignored air traffic control advice to divert to Biak. During an NDB approach to runway 22, the aircraft descended too low, striking a promontory approximately 3,000 feet short of the runway. The impact tore off the left landing gear and caused the aircraft to break into three sections before coming to rest in shallow water.

Controlled Flight Into Terrain (CFIT)

A Zambian Air Force DHC-5D Buffalo carrying the Zambia national football team crashed into the Atlantic Ocean shortly after takeoff from Libreville, Gabon, killing all 30 people on board. Following an engine failure and fire on the left engine, the pilot mistakenly shut down the functioning right engine due to a combination of fatigue and a faulty warning light. The aircraft lost all power and altitude, striking the water approximately 500 metres offshore.

Pilot Error

Indian Airlines Flight 491 crashed shortly after takeoff from Aurangabad Airport after striking a high-clearance truck on a public road adjacent to the runway. The collision damaged the aircraft's left engine and flight controls, causing it to strike power lines and trees before breaking apart and catching fire. The investigation cited the captain's late rotation and poor takeoff technique, combined with the failure of airport authorities to regulate vehicle traffic on the road at the end of the runway.

Pilot Error

Indian Airlines Flight 427 was hijacked by a lone assailant shortly after departing Delhi for Srinagar on April 24, 1993. The aircraft, carrying 135 passengers and 6 crew members, was taken over by a hijacker armed with two pistols and a hand grenade who demanded to be flown to Kabul, Afghanistan. After Pakistan refused the aircraft entry into its airspace, the plane landed at Amritsar, India. Following a tense 11-hour standoff and failed negotiations, commandos from the National Security Guard (NSG) stormed the aircraft in an operation code-named Operation Ashwamedh. The hijacker was killed within minutes; all 140 remaining hostages were rescued without injury.

Security / Sabotage

Japan Air System Flight 451 crashed during landing at Hanamaki Airport after encountering severe windshear associated with a passing cold front. The aircraft, piloted by a relatively inexperienced first officer, suffered a hard landing that caused the landing gear to puncture the fuel tanks, resulting in a fire. Despite the destruction of the aircraft, all occupants successfully evacuated. While official investigation records and some sources like ASN report 76 people on board, other sources including the JTSB and media transcripts indicate 77; between 19 and 20 people sustained injuries. The investigation cited pilot error, specifically the failure to initiate a timely go-around and the captain's poor supervision of the first officer, as contributing factors.

Pilot Error

China Eastern Airlines Flight 583 experienced a series of violent pitch oscillations over the Pacific Ocean after a relief crew member (likely the captain) accidentally deployed the leading-edge slats during cruise flight. The inadvertent slat extension caused the aircraft to pitch up abruptly, and the captain's subsequent manual recovery efforts led to severe over-corrections and a loss of approximately 5,000 feet of altitude. The violent G-forces tossed unrestrained passengers and crew around the cabin, resulting in two fatalities and 156 injuries. The aircraft eventually stabilized and performed an emergency landing at Eareckson Air Station on Shemya Island, Alaska.

Human Factors (Operational)

A baggage handler was fatally injured when she walked into a rotating propeller while the aircraft was stationary at the gate with its engines running. The aircraft, an ATR-42 operating as American Eagle Flight 4127, was experiencing an electrical fault that had extinguished its external lighting, including the navigation and anti-collision lights. The baggage handler, who was on her second day in that role and was unfamiliar with turboprop aircraft, approached the right side of the fuselage to deliver baggage and walked directly into the windmilling propeller of the right engine. While 46 people were on board the aircraft (3 crew and 43 passengers), a total of 49 people were involved in the event including ground personnel.

Human Factors (Operational)

A Fairchild SA227-TT Merlin corporate aircraft crashed during an ILS approach to Tri-Cities Regional Airport, killing all four people on board, including NASCAR champion Alan Kulwicki. The aircraft encountered icing conditions during descent, which led to a dual engine flameout. The NTSB determined that the pilot failed to follow established procedures for the engine anti-ice system and continuous ignition while operating in icing conditions, resulting in ice ingestion and loss of power. During the subsequent engine failure sequence, the pilot failed to maintain sufficient airspeed, resulting in an aerodynamic stall and loss of control.

Pilot Error

Japan Airlines Flight 46E, a Boeing 747 freighter operated by Evergreen International Airlines, suffered the in-flight separation of its number two engine shortly after departing Anchorage. The aircraft encountered severe mountain-wave turbulence at approximately 2,000 feet, which induced dynamic lateral loads that exceeded the structural capacity of the engine pylon. Despite the loss of the engine and significant leading-edge damage, the crew maintained control and successfully returned to Anchorage International Airport without injury to the three crew members and two passengers.

Structural Failure

Palair Macedonian Airlines Flight 301 crashed seconds after takeoff from Skopje Airport during a snowstorm. The aircraft experienced severe rolling oscillations immediately after lift-off, eventually banking 90 degrees to the right before the wingtip struck the ground. The investigation determined that the wings were contaminated by clear ice, which the crew and ground engineer failed to identify or treat with de-icing fluid. The crash was the deadliest in North Macedonia at the time.

Weather

An Iran Airtour Tupolev Tu-154M departing Tehran collided in mid-air with an Islamic Republic of Iran Air Force (IRIAF) Sukhoi Su-24MK. The military jet was part of a formation of five fighters performing maneuvers for the Iranian Revolution Commemoration Ceremony. The collision occurred as the Tu-154 was climbing and the Su-24 was on a visual approach to a parallel runway. Both aircraft were destroyed, and all 133 people on both aircraft were killed.

Human Factors (Operational) · Multi-aircraft

Lufthansa CityLine Flight 5634, operated by Contact Air under a wet-lease agreement, crashed 1,800 meters short of the runway at Paris-Charles de Gaulle Airport during a late-stage runway change. While conducting an ILS approach to runway 27, the crew was instructed to switch to runway 28 after a preceding Korean Air Boeing 747 damaged an engine pod upon landing, forcing a temporary runway closure. During the maneuver to line up with the new runway in instrument meteorological conditions, the aircraft entered a high sink rate and struck the ground tail-first, breaking into two sections.

Pilot Error

Libyan Arab Airlines Flight 1103, a Boeing 727, disintegrated during its approach to Tripoli International Airport. The official Libyan government report stated the aircraft collided with a Libyan Air Force MiG-23UB fighter jet during a training exercise. All 157 people on the Boeing 727 were killed, while the two crew members of the MiG-23 successfully ejected. The accident occurred exactly four years and one day after the Lockerbie bombing, leading to persistent allegations that the aircraft was intentionally destroyed by the Gaddafi regime to frame the West or deflect international pressure.

Mid-air Collision · Multi-aircraft

Martinair Flight 495 crashed during a landing attempt at Faro Airport in severe weather conditions, including heavy rain and windshear. The aircraft struck the runway with high sink rate and lateral force, causing the right main gear to collapse and the wing to separate, followed by a fire and fuselage breakup.

Pilot Error

During a pushback operation at La Guardia Airport, a ground crew member acting as the walker fell for unknown reasons and was fatally struck by the tug. The walker was positioned on the left side of the aircraft using a 15 foot headset cord, which restricted his ability to maintain a safe distance from the moving equipment. The tug driver observed the walker fall in his peripheral vision and stopped the vehicle immediately, but the tug struck the walker before coming to a complete stop.

Human Factors (Operational)

China Southern Airlines Flight 3943 crashed into Mount Tianma during descent after an undetected autothrottle malfunction led to a severe asymmetrical thrust condition. While descending towards Guilin at 7,000 feet, the captain attempted to level off the aircraft. During this maneuver, the number 2 engine power lever remained at idle while the number 1 engine advanced to maintain speed. The resulting power imbalance caused the aircraft to roll 90 degrees to the right and dive into the terrain, killing all 141 people on board.

Human Factors (Operational)

An Aero Caribbean Ilyushin Il-18D struck the side of Pico Isabel de Torres during a circling approach to Puerto Plata in nighttime instrument meteorological conditions. The aircraft was performing the second leg of a non-scheduled charter circuit (Puerto Plata–Santo Domingo–Puerto Plata–Havana). All 34 occupants, including a prominent Dominican chess team and their coach, were killed when the aircraft exploded on impact.

Controlled Flight Into Terrain (CFIT)

Vietnam Airlines Flight 474 crashed into a ridge on Ô Kha mountain during a domestic flight from Ho Chi Minh City to Nha Trang. The aircraft was operating in poor weather conditions associated with Cyclone Forrest when it descended below the minimum safe altitude and deviated approximately 6 kilometers from the W-13 airway. The wreckage was not located for eight days, during which time all but one passenger succumbed to their injuries or the elements. A subsequent rescue mission also ended in tragedy when a Mil Mi-8 helicopter crashed nearby, killing all seven people on board.

Controlled Flight Into Terrain (CFIT)

El Al Flight 1862, a Boeing 747 freighter, crashed into an apartment complex in the Bijlmermeer neighborhood of Amsterdam after its two right-wing engines detached in flight. The accident was caused by the fatigue failure of a fuse pin in the number 3 engine pylon, which led to the engine breaking away and colliding with the number 4 engine, tearing it off as well. The loss of both engines on one side, combined with severe damage to the wing's leading edge and hydraulic systems, rendered the aircraft uncontrollable at low speeds. All four people on board and 39 people on the ground were killed, resulting in 43 total fatalities.
