Aircraft registration Registration and identification assigned to an individual aircraft by national aviation authorities

An aircraft registration is a code unique to a single aircraft, required by international convention to be marked on the exterior of every civil aircraft. The registration indicates the aircraft's country of registration, and functions much like an automobile license plate. This code must also appear in its Certificate of Registration, issued by the relevant National Aviation Authority (NAA). An aircraft can only have one registration, in one jurisdiction, though it is changeable over the life of the aircraft.

Progress D-436

The Progress D-436 is a three-shaft high by-pass turbofan engine developed by the Ukrainian company Ivchenko-Progress. It was initially developed to meet the requirements for late versions of the Yakovlev Yak-42 and the Antonov An-72 in the 1980s. The engine first ran in 1985 and was subsequently certified in 1987. Several variants have been developed and are currently in service with a variety of aircraft.

The flight was a regularly scheduled domestic passenger service from Moscow's Domodedovo Airport to Orsk Airport in Orsk, a city near the border of Kazakhstan, operated by Russian regional carrier Saratov Airlines. The scheduled departure time from Moscow was 14:00. [3] Flight 703 took off from Moscow at around 14:21. [2] [4]

Several minutes after taking off from Moscow, the aircraft's speed and altitude started to fluctuate. Moments before the crash, Flight 703 had gained an altitude of 1,800 metres (5,900 ft) and an airspeed of 600 kilometres per hour (320 kn). It then lost altitude rapidly until it disappeared from the radar at an altitude of around 900 metres (3,000 ft). [3]

The aircraft crashed near the villages of Argunovo and Stepanovskoye in Ramensky District of Moscow Oblast. [5] [6] The accident occurred at 14:27 local time (11:27 UTC), six minutes after take-off from Moscow's Domodedovo Airport. [2] [7] According to a source inside the investigation, a few minutes before the crash the pilot of the aircraft told air traffic controllers about a malfunction, and that he planned to make an emergency landing at Zhukovsky. This report was later dismissed by the investigation committee. [8] Eyewitnesses reported that the aircraft was in flames during its descent to ground. [9] The crash was caught by a surveillance camera in a nearby house. The footage showed that the aircraft slammed into the ground, and immediately burst into flames. [10]

The Russian prosecutor's office launched criminal proceedings for suspected violations of air traffic safety rules. It found reports that the airline had been banned from operating international routes in 2015, and that these had resumed after a change in policy in 2016. The Russian Federal Service for Supervision of Transport (Rostransnadzor) stated that during its examination on the accident aircraft, the airline had violated the procedure for changing oil in the gearboxes, and the procedure for washing the air starter filter. [11]

The Federal Service for Supervision of Transport is an agency of the Government of Russia. The agency is headquartered in Moscow. It was formed in 2004 as a result of government reforms which moved supervisory functions out of several agencies into a new one.

Passengers and crew

According to the flight manifest, Flight 703 was carrying 65 passengers and 6 crew members. Most of the passengers were residents of Orenburg. The Russian Ministry of Emergency Situations said that all but two of the passengers were Russian citizens. One of the foreign passengers was Azerbaijani while the other was Swiss. [12] [5] [6] [13] [14] Everybody on board was killed. [15] [16] [17] Rescue workers reached the site 2.5 hours after the crash. [7]

The captain was a 51-year-old who had accumulated 5,000 hours of total flying experience, of which 2,800 were on the Antonov An-148, but only 58 hours as pilot in command. His medical certificate had expired two days before the accident. [18] The first officer was 35 years old. [12]

The Russian Interstate Aviation Committee (IAC) opened an investigation into the accident. [21] President Vladimir Putin also set up a special commission to investigate the crash. Within the first few hours of the investigation, the Ministry of Transport announced two theories regarding the crash — weather conditions and human factors. [14]

The wreckage of Flight 703 was scattered over a wide area. Officials stated that the radius of the crash site area was about one kilometer, which added suspicion that the aircraft possibly had disintegrated in mid-flight. Since a witness stated it was in flames during its descent, a bomb theory was put forward by several investigators. [10] Both flight recorders (the flight data recorder and the cockpit voice recorder) were found on 12 February. [22] [23]

Saratov Airlines' documents related to the aircraft were impounded as part of the routine investigation. The crash has also caused the Russian Emergency Ministry to discuss whether all Antonov An-148s should be grounded temporarily. Personnel at Moscow Domodedovo Airport were also interviewed. [24]

Russian news agency Rambler News Service (RNS) reported that the pilot of Flight 703 had declined to have the aircraft de-iced before the departure. [25] According to a METAR weather report, the weather at 11:00 included snow showers and a temperature of −5°C at Domodedovo Airport. [26]

On 13 February, the IAC reported that initial analysis of data from the flight data recorder showed that the pitot tube heaters were not turned on and there were discrepancies in the airspeeds being displayed to the pilots, with one airspeed indicator showing increasing airspeed, one showing decreasing airspeed and the third showing no airspeed. The data also showed that the aircraft was under manual control when it pitched nose down some 30° below the horizontal and remained in that attitude until it impacted the ground. [26] The first officer tried to stop sharp descent, but failed to persuade the captain of the loss of control. [18]

On 27 June 2019, the IAC reported that the crash, during climb in instrument meteorological conditions, was caused by the crew's erroneous reactions to unreliable airspeed indications caused by ice blockages of all three pitot probes, which led to the loss of control of the aircraft’s flight dynamics resulting in a dive and collision with the ground. [27]


A crisis centre was set up at Orsk Airport, where relatives of the victims were transported. Monday, 12 February was designated as a day of mourning by the Orenburg government. [28] [29] The head of the Ministry of Labour and Social Affairs, Maxim Topilin, stated that all relatives of the victims would be given 2 million rubles (about US$35,000) each.[ citation needed ] President Vladimir Putin cancelled his planned trip to Sochi in response to the disaster. The government stated that he would coordinate with the special commission he had set up. [30]

On 12 February, Saratov Airlines suspended all An-148 flights as well as all of its flights to Orsk. [31] [32] Saratov Airlines resumed An-148 flights on 16 February after carrying out technical inspections of all An-148s in its fleet. [33] On 20 March, Rostransnadzor suspended all flights by Saratov Airlines after further violations of rules were discovered. [26] On 1 June 2018 Saratov Airlines' air operator's certificate was revoked because of violations of the regulations. [34]

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.
