Aviation Accident Summary Archive

Aeroflot Flight 6551 disintegrated in mid-air and crashed into the Kazakh steppe after an unexplained loss of control during cruise. The aircraft suddenly entered a rapid descent from 7,800 metres, reaching speeds and load factors that caused the right wing and fuselage to fail structurally. Despite an extensive investigation into potential external factors, including military activity and explosive decompression, the underlying cause for the initial upset remains undetermined.

Unknown

A NASA Convair CV-990 and a U.S. Navy Lockheed P-3C Orion collided at approximately 300 feet while on final approach to Moffett Field. The collision occurred after an approach controller cleared the NASA jet to land on Runway 32L, the same runway where the Navy Orion was performing touch-and-go landings. Both aircraft crashed onto the Sunnyvale Municipal Golf Course, approximately 1 kilometer (0.6 miles) short of the runway, resulting in 16 fatalities. One crew member from the P-3 survived after being ejected from the tail section during the impact.

A Vickers Vanguard charter flight carrying members of several British women's guilds crashed into a wooded hillside during a snowstorm while attempting to land at Basel. The flight crew became hopelessly disoriented, misidentifying radio beacons and performing multiple erratic loops south of the airport. Despite warnings from air traffic control and spurious instrument readings, the pilots believed they were established on the localizer. The aircraft struck trees on a ridge near Hochwald, 16 km south of the airport, and somersaulted into a forest. While 108 people perished, 37 survivors were rescued from the severed tail section.

Pilot Error

A mid-air collision occurred over Nantes when a Spantax Convair 990 and an Iberia DC-9 were both assigned to the same flight level and arrival time at the Nantes VOR. Due to a civilian air traffic controller strike, the airspace was managed by military personnel under the Clément Marot Plan. Communication difficulties and poor radar coverage led the Spantax crew to perform an unauthorized 360-degree turn to delay their arrival, placing them directly in the path of the Iberia DC-9. The DC-9 was destroyed, while the Convair managed an emergency landing.

Human Factors (Operational) · Multi-aircraft

Aeroflot Flight X-167 crashed shortly after takeoff from Semipalatinsk Airport, killing all 32 people on board, including the Kyzylorda Region women's basketball team. The aircraft reached an altitude of approximately 100 meters before entering a rapid descent and striking a snow-covered field. Although witnesses reported seeing sparks and a flash of flame, investigators found no evidence of an in-flight explosion or fire. The exact cause remains undetermined, though investigators focused on a spontaneous nose-down stabilizer deflection or pilot incapacitation.

Unknown

On February 26, 1973, a Learjet 24 crashed shortly after takeoff from DeKalb-Peachtree Airport after ingesting a large flock of cowbirds into both engines. The aircraft suffered a total loss of thrust, stalled in a nose-high attitude, and struck an apartment building before coming to rest in a wooded ravine. All seven people on board were killed, and one person on the ground was seriously injured. The investigation revealed that a nearby sanitary landfill had attracted large numbers of birds to the airport environment, a hazard that both the FAA and airport authorities were aware of but had failed to mitigate.

Bird Strike

An Ilyushin Il-18V crashed during a domestic flight after entering a steep spiral dive following a navigation error. The aircraft disintegrated at low altitude due to extreme dynamic loads, killing all 79 people on board.

Human Factors (Operational)

Libyan Arab Airlines Flight 114 was shot down by Israeli F-4 Phantom II fighter jets after the aircraft strayed off course due to navigational errors and entered Israeli-occupied Sinai airspace. The flight crew, believing they were still over Egypt, failed to follow instructions to land at an Israeli airbase, leading the Israeli Defense Forces to believe the airliner was a hostile threat.

Military Action

Aeroflot Flight 141 crashed short of the runway at Prague Ruzyne Airport after an abrupt nose-down pitch during final approach. The aircraft struck frozen ground, broke apart, and was consumed by fire. While the Czechoslovak commission could not definitively determine the cause, Soviet investigators attributed the accident to the captain erroneously moving the horizontal stabilizer from the landing to the flight position at a low altitude, which created an unrecoverable nose-down moment.

Pilot Error

EgyptAir Flight 741 crashed into the Kyrenia Mountains during a night approach to Nicosia International Airport, killing all 37 people on board. The aircraft struck the mountain slope at approximately 2,600 feet, just 117 meters below the summit, while the crew was attempting a visual approach in darkness.

Controlled Flight Into Terrain (CFIT)

A Boeing 707 carrying Nigerian pilgrims from Jeddah crashed while attempting to land at Kano International Airport during a period of high winds and dust. The aircraft touched down nose-wheel first, causing the nose gear to collapse and the aircraft to veer off the runway and catch fire.

Pilot Error

Aeroflot Flight 6263 entered a sudden, high speed downward spiral while cruising toward Perm, leading to an in-flight structural breakup. Although four individuals initially survived the impact, they succumbed to extreme cold before rescue teams could reach the remote site. The official investigation remained inconclusive, though evidence suggested a possible mid-air collision with a projectile.

Unknown

A Pacific Western Airlines Boeing 707 crashed during a back-course ILS approach to Edmonton International Airport, killing all five occupants and 86 cattle. The aircraft was being operated by Pacific Western on behalf of Trans International Airlines. The investigation determined that the flight crew was suffering from severe fatigue and that the first officer, who was flying the aircraft, was inexperienced on the type and returning from a six-week holiday. During the final stages of the approach in turbulent air and blowing snow, the aircraft descended below the required altitude and struck trees and a ridge approximately 3 kilometers short of the runway. The five fatalities included three crew members and two cattle handlers acting as passengers.

Controlled Flight Into Terrain (CFIT)

On December 31, 1972, a Douglas DC-7 cargo aircraft carrying relief supplies for earthquake victims in Nicaragua crashed into the Atlantic Ocean shortly after takeoff from San Juan. The flight was carrying Major League Baseball star Roberto Clemente, who had personally organized the mission. The NTSB determined that the aircraft suffered a total failure of the number 2 engine and a partial power loss on the number 3 engine. The aircraft, which was approximately 4,193 pounds overweight and lacked a properly certified crew, was unable to maintain altitude during a turn and impacted the water at high speed. The investigation revealed the number 2 engine had suffered internal damage during a previous taxiing accident on December 2, 1972, which had not been adequately inspected or repaired.

Mechanical Failure

Eastern Air Lines Flight 401 crashed into the Florida Everglades after the flight crew became preoccupied with a burnt-out landing gear indicator light, failing to notice that the autopilot had been inadvertently disengaged.

Human Factors (CRM)

Braathens SAFE Flight 239 crashed into a wooded hillside in Vestmarka during a night approach to Oslo Airport, Fornebu, killing 40 of the 45 people on board. The crew took a shortcut during the approach and, distracted by non-essential conversation with air traffic control, failed to notice they were significantly off course and below the minimum safe altitude. Navigational errors were compounded by false ILS signals and an incorrectly tuned radio compass, leading the aircraft to strike terrain 16 kilometers west of the airport.

Controlled Flight Into Terrain (CFIT)

A North Central Airlines DC-9 collided with a Delta Air Lines Convair 880 on an active runway at O'Hare International Airport during dense fog. The collision occurred because the Delta crew, acting on an ambiguous instruction from ground control, taxied across Runway 27L while the North Central flight was in the middle of its takeoff roll. The DC-9 struck the Convair's tail and left wing, then crashed and caught fire, resulting in 10 fatalities among the DC-9's passengers.

Human Factors (Operational) · Multi-aircraft

United Air Lines Flight 553 stalled and crashed into a residential neighborhood during a non-precision approach to Chicago Midway International Airport, an intermediate stop on its route to Omaha. The crew failed to manage the aircraft's configuration and airspeed while attempting to level off and subsequently execute a go-around, leading to an aerodynamic stall at an altitude too low for recovery. The accident resulted in 45 fatalities, including 43 of the 61 people on board and 2 individuals on the ground.

Pilot Error

Seven members of the Eritrean Liberation Front attempted to hijack Ethiopian Airlines Flight 708 shortly after its departure from Addis Ababa. During a firefight with onboard security guards, a hijacker armed a hand grenade which was subsequently rolled down the aisle by a passenger to move it away from people. The resulting explosion caused significant damage to the aircraft's flight controls and engines, but the crew successfully returned to the airport and landed. All seven hijackers were killed or died of their injuries; all passengers and crew survived, though some sustained injuries.

Security / Sabotage

A Spantax charter flight carrying West German tourists crashed seconds after takeoff from Tenerife in near-zero visibility. Shortly after liftoff, the aircraft entered a steep, unusual bank at low altitude, lost control, and struck the ground beyond the runway. The investigation determined that the captain suffered from spatial disorientation (somatogyral illusion) while flying in thick fog, leading to the loss of control. At the time, it was the deadliest aviation accident in Spanish history.

Human Factors (Operational)

Ansett Airlines Flight 232 was hijacked by a passenger armed with a sawn-off rifle and a knife during its descent into Alice Springs. The hijacker, Miloslav Hrabinec, demanded a light aircraft and a parachute to facilitate a spectacular suicide in the desert. After the aircraft landed, a standoff ensued involving an undercover police officer and a civilian pilot. During a confrontation at a secondary aircraft, the hijacker shot and seriously wounded the undercover officer. Hrabinec was then wounded by return fire from the civilian pilot and police marksmen before fleeing into a ditch and committing suicide. While the hijacker died, all passengers and crew survived the ordeal.

Security / Sabotage

Southern Airways Flight 49 was hijacked by three armed men shortly after departing Birmingham, Alabama, initiating a 30 hour ordeal that spanned 4,000 miles across the United States, Canada, and Cuba. The hijackers, Melvin Cale, Louis Moore, and Henry Jackson, burst into the cockpit with a gun to a flight attendant's head, declaring, "Billy Bob we're taking over the airplane." Demanding a $10 million ransom, they threatened to crash the aircraft into the High Flux Isotope Reactor at Oak Ridge National Laboratory. After receiving a partial ransom of approximately $2 million in Chattanooga, the aircraft flew to Havana, then Orlando, and finally back to Havana. Despite the FBI shooting out the aircraft's tires in Orlando and the hijackers shooting the first officer in the arm, the crew successfully landed the plane on a flat tire in Cuba, where the hijackers were apprehended.

Security / Sabotage

Aero Trasporti Italiani Flight 327 crashed into a hillside at an elevation of 1,450 feet while descending toward Bari-Palese Airport, killing all 27 people on board, including 24 passengers and 3 crew members. The aircraft, a Fokker F-27 Friendship, was operating a domestic scheduled service from Naples when it impacted terrain approximately 35 kilometers west-southwest of the airport. Investigators determined the accident was a Controlled Flight Into Terrain (CFIT) caused by pilot error during a visual approach. Despite the airport lacking radar and an Instrument Landing System (ILS), the captain reported visual contact with the runway and descended below a safe altitude without adequate navigational guidance.

Controlled Flight Into Terrain (CFIT)

Air Inter Flight 696 crashed into the Forez mountains during a night approach to Clermont-Ferrand in stormy weather. The crew, misled by an erroneous radio compass indication caused by electrical discharges in the atmosphere, believed they were over the Clermont-Ferrand NDB when they were actually 30 km to the east. They initiated a premature descent and struck the Pic du Picot at an altitude of approximately 1,100 meters. Eight passengers survived the impact and were rescued seven hours later.
