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.[1]

Aircraft

The aircraft involved in the accident was a Tupolev Tu-124V, registered CCCP-45061, to Aeroflot. The Tu-124V was a variant of the original Tu-124 which had been introduced in 1962. The 'V' variant of the Tu-124 modified the aircraft to be able to seat 56 passengers, instead of the original 44, and also had increased range and payload capacity. CCCP-45061 was equipped with two Soloviev D-20P turbofan engines and had first flown in 1964. It was assigned to Aeroflot's Lithuania division. At the time of the accident, the aircraft had sustained 14,903 flight hours and 13,832 pressurization cycles.[2]

Crew and passengers

Six crew members were aboard Aeroflot Flight 2022. The flight crew consisted of:

Captain Stepan Boyko
Co-pilot Eugenijus Karnila
Navigator Juozas Časas
Flight engineer Yuno Shamaev
Stewardess Maria Cricova

The crew also included a junior police lieutenant as a sky marshal (they were added after the hijacking of Aeroflot Flight 244 in 1970).[3]

All of the passengers were Soviet citizens, with the exception of one who was a West German citizen. Majority of the passengers were Lithuanians. They included four noted Lithuanian pediatricians, including Petras Baublys, who traveled to a medical conference in Kharkiv. Bodies of the victims were cremated in Moscow on 21 December. The four doctors were buried in a public ceremony attended by Lithuanian First Secretary Antanas Sniečkus in Antakalnis Cemetery.[4]

Accident

At 18:10 MSK on 16 December 1973, CCCP-45061 took off from Vilnius Airport in Lithuania SSR and proceeded east on a flight to Moscow-Vnukovo Airport in Russia with six crew and 45 passengers on board. Flight 2022 climbed to a cruising altitude of 7,800 meters (25,600 ft) and at 19:03 MSK air traffic controllers in Moscow gave the pilots clearance to begin a descent to 5,700 meters (18,700 ft). At 19:11 MSK the pilots reported the aircraft had entered a steep dive and were having difficulties recovering. Just 2,000 meters (6,600 ft) above the ground the pilots were able to briefly stabilize the aircraft however it then entered a stall followed by a spin. At 19:13 MSK the aircraft crashed into the ground near the village of Karacharovo, northwest of Moscow. All 51 people aboard the aircraft were killed. At the time of the crash, visibility was reported to be 2-4 kilometers with haze and cloudy skies.[5]

Cause

An investigation ruled out engine problems or weather having playing a part in the crash. In addition, there were no physical jams in the aircraft's rudder, aileron, and wing trim tab components. Investigators determined that a spontaneous short circuit had caused the elevator trim tab to deflect to and maintain an upward position. As a result, the pilots lost horizontal control and entered into an irrecoverable dive.[5]
