Circumstances:
Following an uneventful flight from Kotlas, the crew started the descent to Arkhangelsk-Talagi Airport. On approach at an altitude of 600 meters, the crew was instructed by ATC to hurry the last and third turn. This caused hasty actions of the crew. The captain asked the flight engineer to reduce power on all three engine to idle but once the altitude of 580 meters was reached on descent, the flight engineer mistakenly shut down all three engines. The pilot tried to restart them but without success because the approach speed was too low. The captain attempted an emergency landing on a road. Upon touchdown, the airplane collided with the support of a power transmission tower and came to rest. All 27 occupants were rescued, among them 23 were injured.
Probable cause:
Erroneous actions on part of the flight engineer who put the power control levers in the 'stop' position instead of the 'idle' position. The lack of proper control on part of the both pilot and copilot was considered as a contributing factor.

Circumstances:
Following a night takeoff from Almaty Airport, while climbing to a height of 120-150 meters, at a speed of 355 km/h, the airplane entered an area of very high outside temperatures (between +30 and +40° C.). High winds and downdrafts were encountered as well. The airplane nosed down then descended and struck the ground at a speed of 400 km/h some 3,996 meters from the end of the runway. It struck a farm, exploded and crashed. None of the 166 occupants survived the crash and nine people on the ground were injured, three seriously. Debris scattered on 840 meters long and 130 meters wide.
Probable cause:
The accident was the consequence of the impact on the aircraft of an unpredictable, rarely encountered intense atmospheric turbulences area with downdrafts up to 14 meters per second (50 km/h) and a tailwind up to 20 meters per second (72 km/h). The following contributing factors were reported:
- The airplane was operated with a total weight close to the maximum allowable for those conditions,
- The high altitude of the airport,
- A high OAT.

Circumstances:
The airplane departed Bologna Airport at 2008LT on a regular schedule service to Palermo, carrying 77 passengers and a crew of four. While cruising at an altitude of 24,000 feet, the airplane disappeared from radar screens and the crew was unable to send any distress call. SAR operations were initiated and few debris and dead bodies were found floating on water about 25 km northeast of Ustica Island, north of Sicily. The main wreckage sank by a depth of 3,500 meters. The cause o the accident could not be determined. On 28 April 1987, Italian authorities decided to refloat the wreckage and traces of T4 explosive was found and several debris. In reference to ATC testimony, two unidentified objects were flying in the area at the time of the accident and it is believed this was two Libyan fighters. One of the pilot probably decided to leave and placed his plane below the DC-9 that exploded when the second pilot tried to shot him down. After the air-air missile was shot, the first fighter leaved the area, causing the missile to struck the DC-9. In 1994, Italian Authorities questioned this theory when a new official document reported that the DC-9 exploded in mid-air due to the denotation of an explosive device placed on board. In 2000, the real cause of this tragedy was still unknown. In 2008, following statements from the ex President of the Italian Republic Francesco Cossiga, the assumption that the airplane may have been shot down by a French missile was rediscussed. The President stated that French and US Authorities thought that the Libyan President Mouammar Kadhafi was on board and must be killed. Many theories were published since 1980 and the exact cause and circumstances of this tragedy remain unknown to date.
Probable cause:
Undetermined.

Circumstances:
The airplane departed Appleton, Wisconsin, at 1245LT on a regular schedule service (ZW965) to Lincoln, Nebraska, with an intermediate stop in Minneapolis. En route, while cruising at 12,000 feet, the crew encountered moderate turbulences and precipitation and was cleared to descend to 8,000 feet then later at 6,000 feet. As turbulences were getting worse, the crew was later cleared to descend to 4,000 feet and finally 3,000 feet. While descending to 6,000 feet, massive water ingestion caused both engines to lose power simultaneously. Both engines were restarted but the Metro couldn't recover and struck a muddy field in a slight nose down, right wing-down attitude. The aircraft bounced and hit the ground 288 feet further on. The plane skidded 1,022 feet before coming to rest inverted. There was no fire. Two passengers were seriously injured while 13 other occupants were killed.
Probable cause:
The flight crew's continued flight into an area of severe thunderstorms, and the resultant precipitation-induced flameout or loss of power of both engines at an altitude from which recovery could not be made. Contributing to the cause of the accident was the failure of the flight crew to utilise all available sources of weather information and the failure of the air traffic control system to disseminate critical weather information to the air traffic controllers and to the crew of Flight 965, the failure of air traffic control supervisory personnel to accomplish key job functions, and the failure of Center Weather Service Unit meteorologists to disseminate critical weather information to the Omaha Radar Approach Control Facility supervisors. Also contributing was the precipitation induced X-band radar attenuation which limited tile ability of airborne weather radar to detect the extent and intensity of the weather disturbances.

Circumstances:
The three engine aircraft deviated from the prescribed flight path by 67 km while circumnavigating a thunderstorm over the mountains with neither crew nor ATC realizing the deviation. At this time, the radio compass did not work properly due to the interference caused by the proximity of the thunderstorm, and the wind component was different than forecast. When the crew reported overflying the outer marker, the aircraft was in fact still 43 km away from it. While descending in clouds, the aircraft crashed at a height of 2,840 metres into the slope of a mountain located 44 km northwest of Dushanbe Airport. All 29 occupants were killed.
Probable cause:
According to officials, the pilots have been hampered in their actions by the lack of visibility caused by poor weather conditions that remains a contributing factor. It is believed that the initial information provided by pilots to air traffic controllers were false and could have misled them. However, the assistance provided by air traffic controllers was insufficient and they did not proceed to any fix point control that should let them identifying the wrong position of the aircraft and thus informing the crew accordingly.
