Aviation Accident Summary Archive

UTA Flight 772 was a scheduled international flight that disintegrated over the Sahara Desert following the detonation of a bomb in the forward cargo hold. The explosion occurred 46 minutes after the aircraft departed N'Djamena, Chad, during its second leg toward Paris. All 170 people on board were killed. Investigations led by French authorities eventually implicated six Libyan officials in the attack, linking it to geopolitical tensions involving Libyan interference in Chad.

Security / Sabotage

A NOAA Lockheed WP-3D Orion, nicknamed 'Kermit' (and referred to by crew as 'The Princess'), suffered a severe engine fire and nearly crashed while penetrating the eyewall of Hurricane Hugo at an altitude of 1,500 feet. The aircraft encountered extreme turbulence, including mesovortices that generated forces between +5.8 g and -3.7 g, causing the number 3 engine to overheat and ignite. The aircraft lost approximately 620 feet of altitude in seconds, with the crew successfully stabilizing the plane just 880 feet above the ocean. They extinguished the fire and circled within the eye for an hour to gain altitude before safely returning to Barbados.

Sensor / Instrument Failure

Partnair Flight 394 suffered a catastrophic in-flight breakup over the Skagerrak, resulting in the deaths of all 55 people on board (50 passengers and 5 crew). The investigation revealed that the aircraft had been maintained with counterfeit, sub-standard bolts and sleeves that failed to secure the vertical stabilizer properly. This allowed the tail to vibrate excessively, eventually tearing the aircraft apart at 22,000 feet.

Mechanical Failure

Cubana de Aviación Flight 9046, a chartered Ilyushin Il-62M, crashed shortly after takeoff from Havana during a severe rainstorm. The aircraft encountered low-altitude windshear and downdrafts that prevented it from maintaining altitude. The crew's decision to retract flaps prematurely while struggling for airspeed exacerbated the loss of lift, leading the aircraft to strike ILS antennas and a hill before crashing into a residential neighborhood. All 126 people on board and 24 people on the ground were killed, making it the deadliest aviation accident in Cuban history.

Pilot Error

Varig Flight 254 crashed into the Amazon jungle after the flight crew entered an incorrect heading into their navigation instruments, leading to fuel exhaustion. The captain misread a four-digit heading on the flight plan, interpreting '0270' (027.0 degrees) as 270 degrees, which sent the aircraft due west instead of north-northeast. After flying in the wrong direction for nearly three hours and failing to locate Belém, the crew attempted a forced landing in the rainforest after both engines flamed out.

Human Factors (Operational)

A Fokker F-27 Friendship disappeared over the Himalayan mountains shortly after departing Gilgit for Islamabad. Despite extensive aerial and ground searches, no wreckage or survivors were ever found, and the aircraft remains missing to this day.

Unknown

A mid-air collision between two hot air balloons occurred when a lower balloon (VH-NMS) ascended into the basket of an upper balloon (VH-WMS). The impact caused the upper balloon's basket to tear the envelope of the lower balloon, leading to a rapid loss of lift and a 2,000-foot plunge to the ground. All 13 people aboard the lower balloon were killed. The investigation highlighted failures in lookout procedures, non-compliance with give-way rules for formation flight, and the absence of mandatory instruments on the upper balloon.

Human Factors (Operational) · Multi-aircraft

Olympic Aviation Flight 545 crashed into the cloud-shrouded Mount Kerkis on the island of Samos, killing all 34 people on board. The aircraft, a Shorts 330-200 named Isle of Milos, was operating a scheduled domestic flight from Thessaloniki. While attempting an approach to Samos Airport, the flight crew continued to operate under Visual Flight Rules (VFR) despite encountering Instrument Meteorological Conditions (IMC). The aircraft deviated from its intended airway and struck the mountain at an altitude of approximately 1,430 meters, resulting in the deadliest accident in the history of the Shorts 330 airframe.

Controlled Flight Into Terrain (CFIT)

Korean Air Flight 803 crashed while attempting a non-precision NDB approach to Tripoli International Airport in dense fog. The aircraft struck four houses and an orchard approximately 2.4 kilometers short of runway 27, breaking into three sections and catching fire. The accident resulted in the deaths of 74 occupants (70 passengers and 4 crew members) out of 199 on board, and 6 people on the ground. While the three flight deck crew members survived the crash, 4 of the 15 cabin crew members were among the fatalities. Investigators determined the crew attempted the landing despite visibility being well below minimums and the airport's Instrument Landing System (ILS) being unserviceable.

Controlled Flight Into Terrain (CFIT)

A fan-disk failure in the tail-mounted engine severed all three hydraulic systems. Using only differential thrust on the two wing engines, the crew flew the crippled DC-10 to a crash-landing at Sioux City, 184 of 296 survived.

Engine Failure

During pushback for a scheduled international flight, a ramp guide was fatally injured when he stumbled and was run over by the aircraft's nose gear. The guide, who was using a ground-to-cockpit microphone, had repeatedly walked behind the nose gear while the aircraft was in motion. The NTSB determined the cause was the ground crew member's failure to follow established safety procedures, compounded by overconfidence in his personal ability.

Human Factors (Operational)

A Soviet MiG-23M fighter jet flew unmanned for over 900 kilometers across Europe after its pilot ejected following a perceived engine failure during takeoff from Poland. The aircraft, stabilized by its autopilot, crossed East Germany, West Germany, and the Netherlands before running out of fuel and crashing into a residence in Bellegem, Belgium, killing an 18 year old student on the ground.

Mechanical Failure

Interflug Flight 102 crashed during a rejected takeoff at Berlin Schönefeld Airport after the crew failed to unlock the elevator flight controls. During the takeoff roll, the aircraft reached rotation speed, but the nose failed to lift because the elevators were physically locked. The captain attempted to abort the takeoff, but the flight engineer shut down all four engines, which disabled the thrust reversers. The aircraft overran the runway at high speed, struck a construction pit, a water tank, and trees before breaking into three pieces and catching fire. While 82 passengers were rescued within minutes, 21 people ultimately died from the accident.

Human Factors (Operational)

Surinam Airways Flight 764 crashed into a forest during a night approach in thick fog at Paramaribo-Zanderij International Airport. The flight crew attempted an ILS approach despite the airport's ILS system being unreliable and not cleared for use. Ignoring multiple warnings from the Ground Proximity Warning System (GPWS), the captain descended the aircraft below the minimum descent altitude, leading to a collision with trees and a subsequent inverted crash.

Pilot Error

EAS Flight 602, a chartered Fairchild FH-227B, crashed into the Col de Tourniol mountain during its approach to Valence, killing all 22 people on board. The investigation determined that the crew committed a significant navigational error by tuning their instruments to the wrong VOR station (LSA instead of VNE). This error, compounded by poor cockpit resource management and the co-pilot's moderate blood alcohol level, led the aircraft to descend into mountainous terrain while the crew believed they were on a safe approach path.

Controlled Flight Into Terrain (CFIT)

Evergreen International Airlines Flight 17 crashed during an emergency return to Carswell Air Force Base after the main cargo door opened in flight. The aircraft became uncontrollable during the turn to final approach, resulting in the deaths of both crew members.

Other

A Nihon YS-11A-600 cargo aircraft crashed during a visual approach to Purdue University Airport after accumulating ice on its horizontal stabilizer. Upon the extension of landing flaps, the aircraft suffered a sudden pitch-down and loss of control, impacting a dirt hill 500 feet short of the runway.

Weather

Air Ontario Flight 1363 crashed shortly after takeoff from Dryden Municipal Airport due to ice accumulation on the wings. The aircraft, a Fokker F28, was operating with an unserviceable auxiliary power unit (APU), which influenced the crew's decision to keep one engine running during the stopover to avoid being stranded at an airport without external start equipment. Because Fokker procedures prohibited deicing while engines were running, the aircraft attempted takeoff with a significant layer of wet snow on its wings, resulting in a loss of lift and a subsequent crash into a wooded area.

Human Factors (Operational)

United Airlines Flight 811 experienced an explosive decompression when its forward lower lobe cargo door blew out during climb at approximately 23,000 feet. The resulting decompression tore a massive hole in the fuselage, ejecting nine passengers from the aircraft. Despite severe damage to the airframe and two engines, the flight crew successfully returned to Honolulu for an emergency landing.

Mechanical Failure

Flying Tiger Line Flight 66, a scheduled cargo service from Singapore to Hong Kong via Kuala Lumpur, crashed into a hillside during a non-precision NDB approach to Kuala Lumpur after the crew misinterpreted a descent clearance. The air traffic controller instructed the flight to descend to two thousand four hundred feet, but the captain interpreted the phrase 'descend two four zero zero' as 'descend to four zero zero' (400 feet). The aircraft descended below the minimum safe altitude and struck terrain approximately 12 kilometers from the airport, killing all four occupants, including three flight crew and one mechanic.

Human Factors (Operational)

Independent Air Flight 1851, a Boeing 707 charter flight, crashed into Pico Alto mountain while on approach to Santa Maria Airport in the Azores. All 144 passengers and crew were killed. The investigation revealed a series of pilot errors, including the use of an incorrect altimeter setting and failure to follow established approach procedures, combined with poor communication from air traffic control.

Controlled Flight Into Terrain (CFIT)

British Midland Flight 092 crashed short of East Midlands Airport after the crew mistakenly shut down the functioning right engine following a mechanical failure in the left engine. A fan blade had fractured in the left engine, causing severe vibration and smoke. Due to a misunderstanding of the aircraft's air conditioning system and misinterpretation of engine instruments, the pilots throttled back and eventually shut down the healthy engine. During the final approach, the damaged left engine failed completely, and the aircraft struck an embankment adjacent to the M1 motorway.

Pilot Error

Two United States Navy F-14A Tomcats shot down two Libyan MiG-23ML Floggers over the Mediterranean Sea after the Libyan aircraft repeatedly maneuvered into a head-on intercept geometry. The engagement occurred approximately 120 miles north of Libya while the USS John F. Kennedy battle group was transiting toward Haifa, Israel. Despite five distinct course changes by the American pilots to avoid a confrontation, the MiG-23s adjusted their headings to maintain a collision course. Interpreting these persistent maneuvers as hostile intent, the U.S. crews engaged with AIM-7 Sparrow and AIM-9 Sidewinder missiles, destroying both Libyan aircraft. A total of six souls were involved in the engagement: four U.S. Navy crew members and two Libyan pilots. Both Libyan pilots were observed to eject, but their subsequent recovery or survival was not confirmed by U.S. forces.
