Aviation Accident Summary Archive

Continental Airlines Flight 12 overran the runway at Kansas City Municipal Airport after hydroplaning on a water-covered runway during heavy rain. Despite the aircraft breaking into three pieces after striking a blast mound, all 66 occupants survived. The investigation highlighted the dangers of short runways for jet aircraft and led to the widespread adoption of runway grooving to improve braking in wet conditions.

Weather

Pan Am Flight 843 suffered a catastrophic uncontained engine failure and fire shortly after takeoff from San Francisco, resulting in the loss of the number 4 engine and approximately 25 feet of the right outer wing. Despite the severe structural damage and a significant fuel fire, the flight crew successfully extinguished the blaze and performed an emergency landing at Travis Air Force Base. All 153 occupants survived without injury in what was widely described as a miracle landing. The failure was traced to improper maintenance procedures during an engine overhaul three days prior.

Human Factors (Maintenance)

Pakistan International Airlines Flight 705, an inaugural service from Karachi to London, crashed during a night approach to Cairo International Airport. The aircraft descended well below the required altitude for its circuit and struck the ground approximately 20 kilometers south of the airport. The crash resulted in 121 fatalities, making it the deadliest accident involving a Boeing 720. While the investigation confirmed the aircraft was in a controlled descent, the specific reason for the crew failure to maintain adequate height remains undetermined.

Controlled Flight Into Terrain (CFIT)

Iberia Flight 401 crashed during a missed approach in heavy fog at Los Rodeos Airport after the aircraft struck ground vehicles near the runway. Despite being informed that visibility was below minimums, the pilot attempted multiple approaches. During a go-around from the second attempt, the aircraft collided with a scraper, a tractor, and a minivan, sustaining damage that prevented it from climbing and leading to a final impact in a nearby gorge.

Pilot Error

British United Airways Flight 1030X crashed during a second landing attempt at Jersey Airport in thick fog, killing 26 of the 27 people on board. The pilot attempted to land in visibility conditions significantly below the airline's authorized minimums. During the approach, the aircraft's starboard wing struck an approach lighting pole, causing the plane to roll inverted and crash into a field short of the runway. A single flight attendant, seated in the rear section that broke away upon impact, was the sole survivor.

Pilot Error

Aeroflot Flight 513 stalled and crashed less than two minutes after takeoff from Kuybyshev Airport when the aircraft's attitude indicator likely failed due to moisture ingress. The aircraft reached an altitude of approximately 40 to 50 meters before the angle of attack increased sharply, leading to a stall from which the crew could not recover. The flight was being operated by a trainee captain in the left seat and a check captain in the right seat, while the flight's designated Captain and Co-pilot remained in the passenger cabin during the departure. A total of 30 people died: all 9 crew members and 21 passengers (including 5 who succumbed to injuries in the hospital).

Sensor / Instrument Failure

Eastern Air Lines Flight 663 crashed into the Atlantic Ocean shortly after takeoff from JFK Airport following an evasive maneuver to avoid a perceived collision with an oncoming Pan Am Boeing 707. The maneuver, performed in darkness over the ocean without a visible horizon, led to spatial disorientation and a loss of control.

Human Factors (Operational)

LAN Chile Flight 107 crashed into the Andes mountains after the pilot deviated from the approved flight plan and airline operations manual. The aircraft struck La Corona Mountain at flight level 120, approximately 1,200 feet below the summit, killing all 88 people on board. The victims included 22 members of the Antonio Varas football team.

Pilot Error

A U.S. Air Force KC-135A Stratotanker crashed into a residential neighborhood in north-eastern Wichita shortly after takeoff, killing all seven crew members and 23 people on the ground, while injuring at least 27 others. The aircraft, heavily laden with 31,000 gallons of jet fuel for a mid-air refueling mission, experienced severe yaw and a loss of control that the crew could not overcome. The resulting explosion and fire incinerated dozens of homes in a predominantly African American neighborhood, making it the deadliest aviation disaster in Kansas history.

Mechanical Failure

Aeroflot Flight 101/X-20 crashed during a night approach to Alma-Ata Airport in heavy fog. The aircraft descended below the glidepath and struck the ground 210 meters (690 ft) to the right of the runway centerline. The investigation revealed that the air traffic controller allowed the landing despite weather conditions being below safety minimums and failed to provide the crew with accurate visibility updates. Additionally, the crew, influenced by a high-ranking official on the flight deck who was not authorized to be on duty, ignored a go-around instruction and attempted to land visually in zero-visibility conditions.

Controlled Flight Into Terrain (CFIT)

A Flying Tiger Line cargo flight crashed into Sweeney Ridge shortly after departing San Francisco International Airport during heavy fog and rain. The aircraft, a Lockheed L-1049H Super Constellation, deviated from its assigned departure radial for undetermined reasons, entering an area of rising terrain. The combination of the pilot's course deviation and environmental factors, including downdrafts and turbulence, prevented the heavily loaded aircraft from maintaining sufficient terrain clearance.

Controlled Flight Into Terrain (CFIT)

TWA Flight 800 (1964) was a scheduled international flight from Kansas City to Cairo that crashed during a rejected takeoff at Rome-Fiumicino Airport. While accelerating for the leg to Athens, the crew received indications of a failure in engine number 4 and a thrust reverser deployment light for engine number 2. Despite aborting below V1, the aircraft failed to decelerate normally and veered right due to asymmetrical thrust, striking a pavement roller in a construction zone. The impact ruptured fuel tanks, leading to a massive fire and center wing tank explosion that killed 49 of the 73 people on board.

Mechanical Failure

Bonanza Air Lines Flight 114 crashed into a ridge in the hills southwest of Las Vegas during a VOR/DME approach in poor weather, killing all 29 people on board. The aircraft struck the terrain just 10 feet below the ridge crest while flying significantly below the required minimum altitude. Investigators determined that the captain misinterpreted a newly published approach chart that lacked clear descent information for the specific approach segment, leading to a premature descent into obstructing terrain.

Controlled Flight Into Terrain (CFIT)

United Airlines Flight 823 crashed into the foothills of the Great Smoky Mountains after an uncontrollable in-flight fire broke out in the fuselage. The aircraft was en route from Washington to Knoxville when it began a rapid descent, trailing smoke and deviating from its course. Witnesses observed the plane flying at extremely low altitudes before it entered a final dive. All 39 people on board were killed, including one passenger who jumped from an emergency exit window shortly before impact.

In-flight Fire

A passenger, Francisco Gonzales, entered the cockpit and shot both pilots with a .357 Magnum revolver, causing the aircraft to plunge into a rural hillside. The murder-suicide resulted in the deaths of all 44 people on board and led to federal regulations requiring cockpit doors to be locked during flight.

Security / Sabotage

A United States Marine Corps RF-8A Crusader crashed into a residential neighborhood in Machida, Tokyo, after suffering a mechanical malfunction during a flight from Okinawa to Atsugi. The pilot successfully ejected at 5,000 feet, but the unguided aircraft struck the Hara-Machida area, destroying seven houses. The crash resulted in four fatalities and 32 injuries, all of which occurred among residents on the ground.

Mechanical Failure

Alitalia Flight 45 crashed into the slopes of Mount Somma during a night visual approach to Naples in poor weather conditions. The crew elected to perform a visual approach despite deteriorating visibility and heavy rain. An abnormally wide downwind turn, likely influenced by unexpected westerly winds and an inaccurate position estimate, led the aircraft into high terrain at an altitude of 2,000 feet.

Controlled Flight Into Terrain (CFIT)

Paradise Airlines Flight 901A crashed into Genoa Peak during a snowstorm after the pilot attempted a visual approach in conditions far below safety minimums. The flight crew became geographically disoriented while attempting to divert toward Reno at an insufficient altitude. The investigation revealed significant safety lapses, including a falsified weather report by a company official and poorly maintained flight instruments, leading to the permanent revocation of the airline's operating certificate.

Controlled Flight Into Terrain (CFIT)

A British Eagle Bristol Britannia crashed into the eastern flank of Mount Glungezer while attempting to land at Innsbruck in poor visibility. The pilot intentionally descended below the minimum safe altitude of 11,000 feet in an attempt to break through cloud cover and establish visual contact with the ground. The aircraft struck the mountain at approximately 8,500 feet, triggering an avalanche that carried wreckage 400 meters down the slope. All 83 people on board were killed in what remains the deadliest aviation accident in Austrian history.

Controlled Flight Into Terrain (CFIT)

Eastern Air Lines Flight 304 crashed into Lake Pontchartrain shortly after departing New Orleans during a multi-leg flight from Mexico City to New York. The investigation revealed that the aircraft suffered a loss of control due to an inoperative pitch trim compensator (PTC) and an abnormal horizontal stabilizer trim position. While climbing through turbulence, the crew likely experienced pilot-induced oscillations and was unable to recover from a steep dive because high G-forces jammed the stabilizer in a nose-down configuration.

Mechanical Failure

An unarmed U.S. Air Force T-39 Sabreliner was shot down by a Soviet MiG-19 after straying into East German airspace during a routine training flight. The aircraft, which had departed Wiesbaden Air Base, suffered a suspected radio failure and pilot disorientation—possibly exacerbated by a violent storm—that prevented the crew from receiving warnings from U.S. radar stations as they drifted off course. After crossing the border, the jet was intercepted by two Soviet MiG-19 fighters and fired upon near Erfurt. All three officers on board were killed. The incident occurred during a period of high Cold War tension and led to a diplomatic standoff when Soviet forces initially denied the crash and blocked U.S. search teams from the site.

Military Action

A United States Air Force B-52D Stratofortress suffered a catastrophic structural failure when its vertical stabilizer broke off during severe winter storm turbulence. The aircraft, which was ferrying two B53 nuclear bombs, became uncontrollable, forcing the crew to bail out into a blizzard. While the pilot and co-pilot survived the ejection and subsequent exposure, three other crew members perished: one remained with the aircraft and two died of hypothermia after landing in deep snow. The nuclear weapons were recovered from the wreckage, sparking a brief internal military dispute regarding the safety of their immediate removal.

Structural Failure

Pan Am Flight 214 was a scheduled flight from San Juan to Philadelphia that exploded in mid-air after being struck by lightning while in a holding pattern near Elkton, Maryland. The lightning strike ignited a volatile fuel/air mixture in the number 1 reserve fuel tank, causing the left wing to disintegrate. All 81 people on board were killed when the aircraft crashed in flames. The accident led to significant changes in aircraft design, including the mandatory installation of lightning discharge wicks and improvements to fuel tank venting systems.

Weather

Trans-Canada Air Lines Flight 831 crashed into a soggy field five minutes after departing Montreal during heavy rain and fog. The aircraft entered a steep, high-speed dive from which the crew could not recover, striking the ground at nearly 485 knots. The investigation was severely hampered by the lack of flight recorders and the total destruction of the airframe. While no definitive cause was found, investigators identified a probable failure in the Pitch Trim Compensator (PTC) system, which may have extended the longitudinal trim to a full nose-down position, leading to a high-speed hydraulic stall that rendered the elevators ineffective.
