Aeroflot Flight 4225 was a Tupolev Tu-154B-2 on a scheduled domestic passenger flight from Alma-Ata Airport (now Almaty) to Simferopol Airport on 8 July 1980. The aircraft had reached an altitude of no more than 500 feet when the airspeed suddenly dropped because of thermal currents it encountered during the climb out. This caused the airplane to stall less than 5 kilometres (3.1 mi; 2.7 nmi) from the airport, crash and catch fire, killing all 156 passengers and 10 crew on board. [1] To date, it remains the deadliest aviation accident in Kazakhstan. [1]
At the time of the accident, Alma-Ata was experiencing a heat wave. It was around 00:39 and Flight 4225 took off from Alma-Ata Airport in Soviet Kazakhstan. [1] Only a few seconds after take off, the flight reached 500 feet (150 m) when the plane reached a zone of hot air and was caught in a downdraft. The Tupolev stalled, plummeted nose down into a farm near the suburbs of Alma-Ata and slid into a ravine, caught fire and disintegrated, killing everyone on board. [2] [3]
The Soviet aviation board concluded that the crash was caused by windshear which took place while the aircraft was near its maximum takeoff weight for the local conditions which included mountains. [2] [4]
The Tupolev Tu-104 is a retired medium-range, narrow-body, twin turbojet-powered Soviet airliner. It was the second to enter regular service, behind the British de Havilland Comet and was the only jetliner operating in the world from 1956 to 1958, when the British jetliner was grounded due to safety concerns.
From 20 to 23 September 1993, during the Sukhumi massacre, separatists in Sukhumi, Abkhazia blocked Georgian troops' overland supply routes as part of the war in Abkhazia. In response, the Georgian government used Sukhumi Babushara Airport to ferry supplies to troops stationed in Sukhumi. Abkhaz forces attacked the airport in an attempt to further block the supply routes.
Almaty International Airport, is the largest international airport of Kazakhstan, surpassing Nursultan Nazarbayev International Airport (NQZ) in Astana and the principal hub of Air Astana. It serves Almaty, the largest and most populous city in the country, and, with its surface transport links, much of the rest of the country.
Aeroflot Flight 5143 was a domestic scheduled Karshi–Ufa–Leningrad passenger flight that crashed near Uchkuduk, Uzbek SSR, Soviet Union, on 10 July 1985. The crash killed all 200 occupants on board. Investigators determined that crew fatigue was a factor in the accident.
Aeroflot Flight 3352 was a regularly scheduled Aeroflot flight from Krasnodar to Novosibirsk, with an intermediate landing in Omsk. While landing at Omsk Airport on Thursday, 11 October 1984, the aircraft crashed into maintenance vehicles on the runway, killing 174 people on board and four on the ground. While a chain of mistakes in airport operations contributed to the accident, its major cause was an air traffic controller falling asleep on duty.
On 1 January 2011, Kolavia Flight 348, a Tupolev Tu-154 on a domestic scheduled passenger flight from Surgut to Moscow, Russia, caught fire while taxiing out for take-off. Passengers were evacuated, but three were killed and 43 injured. A subsequent investigation concluded that the fire had started in an electric panel for which maintenance was never prescribed.
The following is a list of accidents and incidents experienced by Aeroflot during the 1980s. The deadliest accident the carrier experienced in this decade occurred in July 1985, when Flight 5143, a Tupolev Tu-154B-2, stalled en route and crashed near Uchkuduk, then located in the Uzbek SSR, claiming the lives of all 200 occupants aboard the aircraft. The second deadliest accident the company went through in the decade took place in October 1984, when Flight 3352, a Tupolev Tu-154B-1, hit snowploughs upon landing at Omsk Airport, killing 174 of 179 people on board plus four people on the ground. Both accidents combined left a death toll of 378 casualties and involved a Tupolev Tu-154, ranking as the worst ones involving the type, as of February 2012.
Aeroflot Flight 964 was a flight operated by Aeroflot from Kutaisi Airport, Georgia to Domodedovo Airport, Moscow, Russian SFSR. On 13 October 1973, the Tupolev Tu-104 operating on the route crashed during its approach to Moscow, killing all 122 passengers and crew on board. It remains the deadliest accident involving a Tupolev Tu-104.
Aeroflot Flight 5463 was a Soviet domestic passenger flight from Chelyabinsk to Almaty which crashed on 30 August 1983 while approaching Almaty. The Tupolev Tu-134A collided with the western slope of Dolan Mountain at an altitude of 690 m (2,260 ft). As a result of the accident, all ninety people on board were killed. Crew error was cited as the cause of the accident.
Aeroflot Flight 3519 was a Tupolev Tu-154B-2 airline flight on a domestic route from Krasnoyarsk to Irkutsk on 23 December 1984. Shortly after takeoff, the No. 3 engine caught fire, and the airplane crashed during an emergency landing. This killed 110 people; there was only one survivor, and the aircraft was destroyed. The engine fire was caused by a manufacturing defect in the compressor disk.
Aeroflot Flight 3603 was a Tupolev Tu-154 operating a scheduled domestic passenger flight from Krasnoyarsk to Noril'sk, both in the Soviet Union, that crashed while attempting to land on 17 November 1981. Of the 167 passengers and crew on board, 99 were killed in the accident.
Aeroflot Flight 3843 was a Soviet Union commercial flight that crashed on January 13, 1977, after a left engine fire near Almaty Airport. All 90 people on board perished in the crash.
Aeroflot Flight 513 was a domestic scheduled passenger flight operated by Aeroflot that crashed during takeoff from Kuybyshev Airport in the Soviet Union on 8 March 1965, resulting in the deaths of 30 passengers and crew. It was the first fatal accident involving a Tupolev Tu-124.
Aeroflot Flight 2022 was a scheduled Soviet domestic passenger flight between Vilnius Airport in Lithuanian SSR and Vnukovo International Airport in Moscow, Russian SFSR, Soviet Union that crashed on 16 December 1973, killing 51 people on board. The five hundred mile flight suffered a loss of control as a result of a malfunction of its elevator, causing it to crash as it made its final descent into Moscow. At the time of the crash it was the worst accident in aviation history involving a Tupolev Tu-124, since it entered service with Aeroflot in 1962.
The 1958 Aeroflot Тu-104 Kanash crash occurred on 17 October 1958 when a Tupolev Tu-104A operated by Aeroflot flying an international route from Beijing to Moscow crashed in bad weather near the town of Kanash, Chuvashia, Soviet Union, four hundred miles east of Moscow, killing all 80 people on board. The flight was carrying high-level diplomatic delegations from numerous Soviet aligned countries such as China, East Germany, and Czechoslovakia. It was just the second fatal accident involving the Tu-104 which had been introduced into Aeroflot's inventory two years earlier, and the deadliest in the airline's history until the crash of Aeroflot Flight 902 in 1962.
Aeroflot Flight 6709 was a Tupolev Tu-154B on a domestic route from Baku to Leningrad on 19 May 1978. While cruising, fuel starvation affected the flow of fuel to the aircraft's three Kuznetsov NK-8 engines, causing the engines to stop. This issue was possibly as a result of poor aircraft design.
Aeroflot Flight 699 was a scheduled flight, operated by Tupolev Tu-154B CCCP-85254, from Moscow Domodedovo Airport to Krasnovodsk Airport that crashed on approach to its destination.
Aeroflot Flight 8556 was a scheduled domestic passenger flight from Sukhumi to Leningrad. It crashed 13 meters short of the runway on approach killing 13 passengers.

The aircraft failed to become airborne and struck a residential area, killing all 24 on board and four more people on the ground. An investigation revealed that the aircraft's cargo was improperly loaded and partially undocumented, causing it to become overloaded.
