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. [1] All 52 passengers and crew aboard the aircraft perished in the crash. [1]

Russian language East Slavic language

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.

Aircraft

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. [2] [3]

Crew

Six crew members were aboard the flight. The cockpit crew consisted of: [4]

Pilot in command crew position responsible for control of an aircraft and ultimately responsible for all operations of the aircraft

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.

First officer (aeronautics) civil aviation

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.

Synopsis

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. [2]

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.)

Rudder device to steer a vehicle

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.

Aileron aircraft control surface used to induce roll

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'.

Causes

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. [1] [2]

1971 January 22 Surgut Aeroflot Antonov An-12 crash

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.

Aeroflot accidents and incidents in the 1990s Wikimedia list article

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.
