A Piedmont Airlines Boeing 727 collided mid-air with a Cessna 310 shortly after departing Asheville, North Carolina. The Cessna, which was inbound to Asheville, deviated from its assigned IFR clearance and entered the airspace reserved for the climbing jetliner. The collision occurred at approximately 6,132 feet, causing both aircraft to disintegrate and crash near Hendersonville. All 79 occupants (74 passengers and 5 crew) on the Boeing 727 and all 3 occupants of the Cessna were killed. The accident was the first major investigation conducted by the newly formed National Transportation Safety Board (NTSB).

Thai Airways International Flight 601 crashed into the sea while attempting to land at Kai Tak Airport during a typhoon. The aircraft, a Sud Aviation Caravelle III, undershot runway 31 after the crew failed to maintain the correct glide slope during an ILS approach in heavy rain and reduced visibility. The investigation determined that the pilots descended below the decision height without visual contact and executed abrupt heading changes that exacerbated a high rate of descent. While wind shear and downdrafts from Typhoon Anita were contributing factors, the primary cause was the crew's failure to adhere to standard operating procedures for a monitored instrument approach.

Pilot Error

Mohawk Airlines Flight 40 suffered a catastrophic in-flight fire and structural failure of the tail section, leading to a total loss of control. The investigation revealed that a malfunctioning non-return valve allowed high-temperature engine bleed air to flow backward through the auxiliary power unit (APU) and into the airframe plenum chamber. This ignited the acoustic linings, and the resulting fire melted an aluminum partition, exposing pressurized hydraulic lines. The fire, fueled by Skydrol hydraulic fluid, burned through the vertical fin and destroyed the pitch control systems, causing the aircraft to dive into a wooded area near Blossburg, Pennsylvania. All 34 people on board were killed.

Mechanical Failure

A British Midland Airways Canadair C-4 Argonaut crashed in the center of Stockport during a second approach to Manchester Airport following a double engine failure. The investigation revealed a design flaw in the fuel system that allowed fuel to inadvertently transfer between tanks, leading to starvation despite sufficient total fuel on board. While 12 people were rescued from the wreckage, 72 perished, primarily due to a post-crash fire and a concertina collapse of passenger seats that trapped occupants by their legs.

Mechanical Failure

An Air Ferry Douglas DC-4, operating a charter flight for Lyons Tours, crashed into Mount Canigó during its approach to Perpignan. All 88 people on board were killed. The investigation revealed that the flight crew had been incapacitated by carbon monoxide poisoning originating from a faulty cabin heater, leading to irrational behavior and navigation errors.

Human Factors

A Globe Air Bristol Britannia, carrying European tourists back from Southeast Asia, crashed into a hill during a thunderstorm while attempting to land at Nicosia International Airport. The flight had diverted to Cyprus due to severe weather at its planned stop in Cairo. After an aborted first approach, the aircraft struck a hillock during a second, low altitude circuit in poor visibility. The investigation highlighted severe crew fatigue, as the pilots had exceeded their legal duty limits by several hours, and the first officer had minimal experience on the aircraft type.

Controlled Flight Into Terrain (CFIT)

A Delta Air Lines Douglas DC-8-51 crashed into a residential area and motel complex during a training flight, killing all six occupants and 13 people on the ground. The crew was conducting a simulated two-engine-out approach to New Orleans International Airport when the instructor pilot prematurely deployed full landing flaps. The resulting drag caused the airspeed to decay significantly. Instead of applying thrust to compensate, the trainee pilot attempted to maintain the glidepath by raising the aircraft's nose. This led to a loss of control, characterized by a rapid yaw and roll to the left, from which the crew could not recover at low altitude.

Pilot Error

South African Airways Flight 406, a Vickers Viscount named Rietbok, crashed into the Indian Ocean during a night approach to East London in poor weather. The aircraft was performing a scheduled flight from Port Elizabeth when it disappeared shortly after reporting its position at 2,000 feet with the coastline in sight. Despite extensive search efforts, the main wreckage was not recovered during the initial investigation, and all 25 people on board were killed. The official Board of Inquiry could not determine a definitive cause due to a lack of physical evidence, though it considered pilot incapacitation due to a heart attack as a possibility that could not be excluded.

Unknown

West Coast Airlines Flight 720 crashed into Stukel Mountain shortly after takeoff from Klamath Falls Airport due to heavy ice and snow accumulation on the airframe. The aircraft had been parked in a hangar for maintenance but was exposed to falling snow and rain for 11 minutes after a tow tractor became stuck during pushback. The crew elected to take off without de-icing the wings or control surfaces. During the climb, the aircraft suffered a loss of control, swerving and failing to maintain a steady heading before impacting a ridge four miles southeast of the airport.

Pilot Error

A Trans World Airlines DC-9 collided in mid-air with a private Beechcraft Baron 55 while descending toward Dayton Municipal Airport. The accident occurred in uncontrolled airspace under Visual Flight Rules (VFR), where both crews were responsible for maintaining a see and avoid lookout. Despite receiving a traffic advisory from Dayton radar approach 18 seconds before impact, the DC-9 crew did not detect the smaller aircraft in time to maneuver. The high rate of descent and excessive speed of the DC-9, combined with the inherent difficulty of detecting small aircraft on radar and visually against a hazy background, led to the collision. All 25 people on the DC-9 and the sole pilot of the Beechcraft were killed.

Human Factors (Operational) · Multi-aircraft

Lake Central Airlines Flight 527 suffered a catastrophic in-flight breakup after the right propeller separated and sliced through the fuselage. The failure was traced to a manufacturing defect where a critical hardening process, nitriding, was omitted from a propeller torque piston. This omission led to rapid wear of the piston splines, causing the propeller to overspeed beyond its structural limits. The resulting centrifugal forces tore the blades from the hub, leading to a total loss of aircraft control and structural integrity.

Mechanical Failure

Varig Flight 837 crashed during an unstable approach to Roberts International Airport after the captain attempted to salvage a landing from an excessive altitude. Despite being cleared to 3,000 feet, the aircraft remained at 4,500 feet until it was vertically over the VOR station. The captain elected to perform a manual VOR/Locator procedure but found himself at 800 feet over the final locator beacon, nearly 300 feet above the prescribed profile. In an attempt to reach the runway, he initiated a steep descent of up to 1,500 feet per minute. The aircraft failed to level off in time, striking the ground 6,023 feet short of the runway threshold and erupting into flames. The accident resulted in the deaths of 51 people on board and 5 people on the ground, making it the deadliest aviation disaster in Liberian history.

Pilot Error

Garuda Indonesian Airways Flight 708 crashed short of the runway at Mapanget Airport during a landing attempt in marginal weather. The Lockheed L-188C Electra was performing a steep, unstable approach to Runway 18 after the pilot realized the aircraft was too high and left of the centerline. During the corrective maneuver, the airspeed dropped below the target threshold speed, resulting in an excessive rate of sink. The aircraft struck the ground 156 feet short of the runway threshold, which caused the undercarriage to collapse. The airframe skidded and caught fire, resulting in 22 fatalities among the 92 occupants.

Pilot Error

Aeroflot Flight 5003, an Antonov An-12B cargo flight, crashed shortly after takeoff from Novosibirsk when an intense in-flight fire broke out in the cargo hold. The aircraft had been in the air for less than two minutes and reached an altitude of only 200 meters when the crew attempted an emergency landing in a snow-covered field. During the descent in poor visibility, the aircraft struck the ground in a left bank and exploded, killing all six crew members. Investigators determined the fire likely originated from flammable industrial materials in the cargo, though the exact ignition source could not be identified due to the severity of the wreckage damage.

In-flight Fire

TABSO Flight 101 crashed into the Little Carpathians hills shortly after departing Bratislava Airport, killing all 82 people on board. The flight had diverted to Bratislava due to poor weather at its scheduled stop in Prague. Upon resuming the flight in darkness, the crew was instructed to maintain a low altitude of 300 metres to ensure separation from a slower aircraft. However, the Ilyushin Il-18 deviated from the safe departure path and impacted a wooded slope at approximately 250 knots. The investigation cited a failure by the crew to properly evaluate the terrain and weather conditions, though the official cause remained technically undetermined due to diplomatic friction between Bulgarian and Czechoslovak authorities.

Controlled Flight Into Terrain (CFIT)

A Pan Am cargo flight crashed in the Soviet occupation zone near Berlin during a night approach in poor weather. The aircraft descended below its cleared altitude for unknown reasons, striking the ground shortly after receiving ILS clearance in what modern safety taxonomy classifies as Controlled Flight Into Terrain (CFIT). The investigation was severely hampered by the Soviet Union's refusal to return approximately 50 percent of the wreckage, including the flight recorders and critical navigation systems.

Unknown

An All Nippon Airways NAMC YS-11 crashed into the Seto Inland Sea during a night go-around at Matsuyama Airport. After a long touchdown and subsequent lift-off, the aircraft failed to maintain altitude during a left turn, plunging into the water for reasons that investigators could never definitively determine.

Unknown

West Coast Airlines Flight 956 crashed into a ridge in the Mount Hood National Forest during a night approach to Portland, marking the first hull loss of a Douglas DC-9. The aircraft, which had been in service for only five days, descended to 4,000 feet despite being cleared to a minimum altitude of 9,000 feet. The investigation determined that the crew followed all air traffic control instructions except for the altitude restriction, but investigators could not establish why the descent continued into obstructing terrain.

Controlled Flight Into Terrain (CFIT)

Ansett-ANA Flight 149 suffered a catastrophic in-flight fire and structural failure after a cabin pressurization blower on the number 2 engine disintegrated. The failure initiated a fire that breached a wing fuel tank, weakening the main spar until the left wing separated in flight. The aircraft disintegrated at approximately 3,500 to 4,000 feet, killing all 24 people on board. The investigation, the most detailed in Australian history at the time, was the first in the country to utilize flight data recorder information.

Mechanical Failure

Britannia Airways Flight 105 crashed into a forest during a night approach to Ljubljana Brnik Airport after the crew failed to correctly set their altimeters. The pilots conducted the approach as if their instruments were set to the airport's field pressure (QFE), when they were actually set to sea level pressure (QNH), resulting in the aircraft flying approximately 1,160 feet lower than intended. The aircraft struck trees 2.8 kilometers from the runway threshold, killing 98 of the 117 people on board.

Controlled Flight Into Terrain (CFIT)

Braniff International Airways Flight 250 suffered an in-flight structural failure and crashed near Falls City, Nebraska, after encountering extreme turbulence from a squall line of severe thunderstorms. The aircraft's tailplane and vertical stabilizer failed under the stress of an intense updraft and subsequent control inputs, followed by the failure of the right wing. All 42 people on board were killed in what remains the deadliest aviation disaster in Nebraska history.

Weather

An Air New Zealand Douglas DC-8-52 crashed during a training flight at Auckland International Airport after an instructor inadvertently deployed reverse thrust while simulating an engine failure. During the takeoff roll, as the instructor rapidly pulled the number four engine thrust lever to idle to simulate a failure, the rapid movement generated enough inertia to cause the thrust brake lever to enter the reverse idle detent. This created massive asymmetrical drag and thrust imbalance. The aircraft rotated steeply, rolled to the right, and struck the ground just seconds after liftoff. Two of the five crew members on board were killed.

Human Factors (Operational)

A newly built Hawker Siddeley Trident 1C crashed during its first production test flight after entering an unrecoverable deep stall, also known as a superstall. The crew was conducting stalling tests to qualify for a Certificate of Airworthiness and had intentionally disabled the aircraft's automatic stall warning and recovery systems to determine the actual aerodynamic stall margin. During the final test run, the pilot delayed recovery action too long, allowing the aircraft to enter a deep stall and subsequent flat spin. All four crew members on board were killed when the aircraft struck the ground near Felthorpe.
