Aeroflot Flight 1802 (Russian : Рейс 1802 АэрофлотаReys 1802 Aeroflota) was a commercial flight from Vinnytsia to Moscow that crashed after the rudder to deflected sharply and the propellers feathered on 15 May 1976. All 52 passengers and crew aboard the aircraft perished in the crash.
Russian is an East Slavic language, which is official in the Russian Federation, Belarus, Kazakhstan and Kyrgyzstan, as well as being widely used throughout Eastern Europe, the Baltic states, the Caucasus and Central Asia. It was the de facto language of the Soviet Union until its dissolution on 25 December 1991. Although, nowadays, nearly three decades after the breakup of the Soviet Union, Russian is used in official capacity or in public life in all the post-Soviet nation-states, as well as in Israel and Mongolia, the rise of state-specific varieties of this language tends to be strongly denied in Russia, in line with the Russian World ideology.
Vinnytsia is a city in west-central Ukraine, located on the banks of the Southern Bug.
Moscow is the capital and most populous city of Russia, with 13.2 million residents within the city limits, 17 million within the urban area and 20 million within the metropolitan area. Moscow is one of Russia's federal cities.
The aircraft involved in the accident was an Antonov An-24RV, registered CCCP-46534 to Aeroflot. The aircraft rolled off the final assembly line February 27, 1975. In the aircraft's service life it accumulated 2,996 flight hours and 2,228 pressurization cycles.
Six crew members were aboard the flight. The cockpit crew consisted of:
The pilot in command (PIC) of an aircraft is the person aboard the aircraft who is ultimately responsible for its operation and safety during flight. This would be the captain in a typical two- or three-pilot aircrew, or "pilot" if there is only one certificated and qualified pilot at the controls of an aircraft. The PIC must be legally certificated to operate the aircraft for the specific flight and flight conditions, but need not be actually manipulating the controls at any given moment. The PIC is the person legally in charge of the aircraft and its flight safety and operation, and would normally be the primary person liable for an infraction of any flight rule.
In commercial aviation, the first officer is the second pilot of an aircraft. The first officer is second-in-command of the aircraft to the captain, who is the legal commander. In the event of incapacitation of the captain, the first officer will assume command of the aircraft.
A navigator is the person on board a ship or aircraft responsible for its navigation. The navigator's primary responsibility is to be aware of ship or aircraft position at all times. Responsibilities include planning the journey, advising the ship's captain or aircraft commander of estimated timing to destinations while en route, and ensuring hazards are avoided. The navigator is in charge of maintaining the aircraft or ship's nautical charts, nautical publications, and navigational equipment, and he/she generally has responsibility for meteorological equipment and communications. With the advent of GPS, the effort required to accurately determine one's position has decreased by orders of magnitude, so the entire field has experienced a revolutionary transition since the 1990s with traditional navigation tasks being used less frequently.
N. Sukalo worked as the stewardess for the flight.
Thunderclouds were present above the Chernihiv region sky for the duration of the flight. Moderate wind blowing southwest on a bearing of 250° at 6 m/s was present, along with moderate rain showers. Visibility on the ground at the airport was 10 kilometers with a cumulonimbus cloudcover. Flight 1802 was flying at an altitude of 5700 meters with a speed of 350 km/h when at approximately 10:47 the rudder suddenly deviated 25° to the right, changing the roll angle and yaw. The pilots responded quickly to this deflection by adjusting the ailerons in their attempts to reduce the roll. A few seconds later the rudder deflected 9°, and the elevators deviated resulting in 30° to pitch (nose held up). The airliner reached sharp angles of attack, and thus went into a tailspin. At the time of entry into the spin, the propellers were feathered. The airliner crashed 14.5 kilometers southeast of Chernigovskiy airport on a bearing of 245° at 10:48 with a rate of descent at nearly 100 m/s in uncontrolled flight. All 52 people on board the aircraft perished in the crash.
Chernihiv Oblast is an oblast (province) of northern Ukraine. The administrative center of the oblast is the city of Chernihiv. Within the Oblast are 1,511 settlements of various sizes ranging from large cities to very small villages. Population: 1,055,673 (2015 est.)
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other conveyance that moves through a fluid medium. On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull (watercraft) or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics.
An aileron is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll, which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'.
The aircraft crashed due to loss of control caused by the rudder deflecting when the autopilot was disconnected, but the root cause of the rudder deflection was never determined. It is possible one of the pilots accidentally pushed the rudder trim control switch. Electrical failure could also have caused the mechanical issues.
This is a list of aviation-related events from 1976:
The 1971 January 22 Surgut Aeroflot Antonov An-12 crash occurred on 22 January 1971, when an Aeroflot Antonov An-12B, registered CCCP-11000, flying from Omsk Tsentralny Airport, in the Soviet Union's Russian Soviet Federated Socialist Republic (RSFSR), crashed 15 km (9.3 mi) short of the runway on approach to Surgut International Airport, Surgut, RSFSR. An investigation found the aircraft's ice protection system was ineffective because the engine bleed air valves were closed during the flight; ice therefore built up on the aircraft causing it to go out of control.
After the dissolution of the Soviet Union in December 1991, its former republics started establishing their own carriers from the corresponding directorates Aeroflot had at these countries, causing the airline to shrink drastically. The fleet reduced from several thousand aircraft to a number slightly over 100 in 1993, helping the former Soviet Union's national airline to improve its accidents and incidents record sharply. The company experienced 42 events between 1990 and 1991 only, and had 41 occurrences in the rest of the decade. Despite this, the three deadliest accidents the airline went through in the decade occurred in the post-Soviet era, leaving a death toll of 257, each one involving more than 50 fatalities.
Aeroflot Flight 1491 was a scheduled domestic passenger flight from Moscow-Vnukovo Airport to Kharkiv Airport in the USSR that crashed on 18 May 1972 while descending to land in Kharkiv, killing all 122 passengers and crew aboard the Antonov An-10.
Aeroflot Flight 15 was a passenger flight from Moscow-Domodedovo Airport to Petropavlovsk-Kamchatsky Airport with a stopover at Yemelyanovo Airport that crashed on 29 February 1968 en route to Petropavlovsk. All but one aboard the aircraft were killed in the crash.
Aeroflot Flight 1036 was a domestic scheduled passenger flight operated by Aeroflot that crashed during takeoff from Sochi International Airport on 1 October 1972. All 109 people aboard the Ilyushin Il-18V perished in the crash. It is the second worst accident involving an Ilyushin Il-18 and it was the worst accident involving one at the time.
Aeroflot Flight 415 was a domestic scheduled passenger flight operated by Aeroflot from Lviv to Sochi with a stopover in Simferopol. On 28 July 1962 the Antonov An-10 operating the route crashed near Gagra, Abkhaz ASSR, Georgian SSR, killing all 81 passengers and crew on board.
Aeroflot Flight 811 was a scheduled Soviet domestic passenger flight from Komsomolsk-on-Amur to Blagoveshchensk that collided mid-air on 24 August 1981 with a Tupolev Tu-16K strategic bomber over Zavitinsky District in Amur Oblast, Russian SFSR, Soviet Union. The collision between Aeroflot's Antonov An-24RV and Tupolev Tu-16K occurred at an altitude of 5,220 metres (17,130 ft), killing 37 people on both aircraft. The sole survivor, 20-year-old passenger Larisa Savitskaya from Antonov An-24RV, was rescued on the third day after the accident.
The 1969 Yukhnov mid-air collision occurred when an Ilyushin Il-14M, operating as Aeroflot Flight 831, a scheduled domestic passenger flight from Moscow-Bykovo Airport to Simferopol Airport, Crimea collided in the air on 23 June 1969 with an Antonov An-12BP of the Soviet Air Force over the Yukhnovsky district of Kaluga Oblast, in the Russian SFSR of the Soviet Union. All 120 occupants of both aircraft perished in the crash.
The 1976 Anapa mid-air collision was the collision of Aeroflot Flight 7957 and Aeroflot Flight 31 on 9 September 1976, off the coast of Anapa in the Soviet Union. All 70 people on the two aircraft were killed in the crash. The primary cause of the accident was determined to be error by the air traffic controller; investigators never recovered the fuselage of the Yak-40.
Aeroflot Flight 5003 was a Soviet domestic cargo flight that crashed during climb out on 14 January 1967. The Antonov An-12B was flying between Novosibirsk and Krasnoyarsk in Russia with a crew of six when it crashed. It was carrying industrial parts from Moscow to Khabarovsk with several intermediate stops in between, however it caught fire shortly after takeoff, resulting in a fatal accident. At the time Flight 5003 was being operated by Polar Aviation Management under Aeroflot.
Aeroflot Flight 2022 was a scheduled Soviet domestic passenger flight between Vilnius Airport in Lithuania and Vnukovo International Airport in Moscow, Russia that crashed on 16 December 1973, killing all 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.
Aeroflot Flight 13 was a scheduled Soviet domestic passenger flight from Baku, Azerbaijan to Fort-Shevchenko in Kazakhstan that crashed on 18 August 1973 shortly after takeoff, killing 56 of the 64 passengers and crew aboard. The Antonov An-24 had suffered an engine failure on takeoff and was attempting to return to the airport when it struck an oil rig cable at low altitude resulting in a crash. At the time, it was the second worst accident involving the An-24 and remains the second worst aviation accident in Azerbaijani history.
On July 18 1970, a Soviet Antonov An-22 crashed in the Atlantic Ocean between Iceland and Greenland, while on its way to Halifax, Canada. It was the first crash of the Antonov 22 model and it resulted in the deaths of all 22 people on board.
On Sunday August 3, 1969 an Antonov An-24 operating Aeroflot Flight 826 crashed resulting in the death of all 55 people on board. An investigation revealed the cause of the accident was an in flight failure of the propeller attached to "No. 1" (left) engine.
Aeroflot Flight 51 was a scheduled domestic passenger flight operated by an Antonov An-24 that crashed on approach to Liepāja International Airport on 30 December 1967, resulting in the death of 43 of the 51 people on board. The investigation revealed the cause of the accident to be pilot error.
Aeroflot Flight 2174 was a scheduled domestic passenger flight operated by an Antonov An-24B that crashed on approach to Saratov Tsentralny Airport on Wednesday December 1, 1971, resulting in the death of all 57 people on board. An investigation revealed the aircraft entered icing conditions leading to a loss of control.
Aeroflot Flight 1969 was a passenger flight operated by an Antonov An-10 that crashed during the approach to Luhansk on March 31, 1971, resulting in the death of all 65 people on board. An investigation revealed that the Antonov's right wing failed structurally during approach to Luhansk International Airport.
Aeroflot Flight 36 was a scheduled domestic Aeroflot passenger flight from Chernivtsi International Airport to Kyiv International Airport (Zhuliany), Ukrainian Soviet Socialist Republic that crashed on 17 December 1976 near Kiev airport, resulting in 48 fatalities and 7 survivors.
