Saratov Airlines Flight 703 was a scheduled domestic passenger route connecting Moscow Domodedovo Airport to Orsk Airport in Russia. On 11 February 2018, the aircraft assigned to this flight, an Antonov An-148-100B, crashed shortly after departure, resulting in the deaths of all 71 individuals aboard, including 65 passengers and six crew members.

Accident

Route of Saratov Airlines Flight 703

Operated by Russian regional airline Saratov Airlines, Flight 703 was a routine domestic service from Moscow’s Domodedovo Airport to Orsk Airport in the city of Orsk, situated near the Kazakhstan border. The planned departure time was at 14:00 local time. The aircraft departed Moscow at approximately 14:21.

Within minutes after takeoff, fluctuations were observed in both the plane's altitude and speed. Just prior to the accident, Flight 703 had climbed to an altitude of about 1,800 metres (5,900 ft) and reached an airspeed near 600 kilometres per hour (320 kn; 370 mph). Subsequently, it rapidly lost altitude until it vanished from radar at roughly 900 metres (3,000 ft).

The crash occurred close to the villages of Argunovo and Stepanovskoye within Moscow Oblast’s Ramensky District. The incident took place at 14:27 local time (11:27 UTC), roughly six minutes following takeoff from Domodedovo Airport. According to an investigative source, shortly before the crash, the pilot informed air traffic control about a technical malfunction and intended to perform an emergency landing at Zhukovsky International Airport. This claim was subsequently refuted by the official investigation committee. Eyewitnesses reported seeing the aircraft engulfed in flames during its descent. Surveillance footage from a nearby residence captured the moment when the airplane collided with the ground and immediately ignited.

Following the accident, Russian prosecutors initiated a criminal investigation focusing on potential breaches of air traffic safety regulations. Information emerged indicating that the airline had been prohibited from conducting international flights in 2015 but resumed such operations following policy changes in 2016. The Russian Federal Service for Supervision of Transport (Rostransnadzor) revealed that during their inspection of the accident aircraft, Saratov Airlines failed to comply with required procedures for gearbox oil changes and cleaning of the air starter filter.

Aircraft

The airplane involved in the incident was an Antonov An-148-100B manufactured by the Voronezh Aircraft Production Association, bearing the registration RA-61704 and MSN 27015040004. It was equipped with two Progress D-436 engines. The aircraft's maiden flight occurred in May 2010, followed by its delivery to Rossiya Airlines in June 2010. During its operational history, it experienced two minor events: an engine surge on 28 July 2013 that required shutting down one engine mid-flight, and a nose landing gear malfunction during takeoff on 23 August 2013. The plane remained active with Rossiya until 2015. After being stored for several years, it was leased to Saratov Airlines starting February 2017, approximately one year before the crash.

Passengers and crew

Flight 703's manifest listed a total of 65 passengers alongside 6 crew members. The majority of passengers originated from Orenburg. The Russian Ministry of Emergency Situations reported that all but two passengers held Russian citizenship. Among the non-Russian travelers were one individual from Azerbaijan and another from Switzerland. Tragically, there were no survivors among those onboard. Emergency responders arrived at the crash location approximately two and a half hours after the accident.

The flight captain was Valery Gubanov, a 51-year-old Russian pilot who had amassed around 5,000 total flight hours, including about 2,800 hours on the Antonov An-148 model; however, he had only 58 hours serving as pilot-in-command. Notably, his medical certification had expired two days prior to the accident. The first officer, Sergei Gambaryan, was aged 35.

Investigation

Altitude and speed profile of Saratov Airlines Flight 703

The Russian Interstate Aviation Committee (IAC) initiated an inquiry into the incident. Additionally, President Vladimir Putin established a dedicated commission to oversee the crash investigation. Within hours, the Ministry of Transport proposed two primary hypotheses for the cause: adverse weather conditions and human error.

Debris from Flight 703 was dispersed across a broad zone. Authorities indicated that the crash site spanned approximately one kilometer (0.62 miles) in radius, raising concerns that the aircraft might have broken apart mid-flight. Since eyewitness accounts described the plane as engulfed in flames during its descent, some investigators considered an explosive device as a possible factor. Both flight recorders—the cockpit voice recorder and flight data recorder—were recovered on 12 February.

As part of standard investigative procedures, Saratov Airlines' documents pertaining to the aircraft were seized. The accident prompted the Russian Emergency Ministry to deliberate on temporarily grounding all Antonov An-148 models. Personnel working at Moscow Domodedovo Airport were also questioned.

According to Russian news outlet Rambler News Service (RNS), the pilot of Flight 703 opted not to have the plane treated with de-icing before departure. METAR weather data recorded at 11:00 indicated snow showers and a temperature of approximately −5 °C (23 °F) at Domodedovo Airport.

On 13 February, the IAC disclosed that preliminary examination of flight data revealed that the pitot tube heaters had not been activated. The recorded airspeeds displayed inconsistencies: one indicator showed increasing speed, another decreasing speed, and the third remained constant with no speed. The data further indicated that manual control was engaged when the aircraft pitched sharply nose-down about 30° below level flight and maintained this attitude until ground impact. The first officer attempted to arrest the rapid descent but was unable to convince the captain that control had been lost.

On 27 June 2019, the IAC concluded that during climb under instrument meteorological conditions, erroneous pilot responses to unreliable airspeed readings—caused by ice obstructing all three pitot probes—resulted in loss of control over the aircraft's flight dynamics, culminating in a steep dive and collision with terrain.

Aftermath

A crisis response center was established at Orsk Airport to assist the families of the victims who were brought there. The Orenburg regional authorities declared Monday, 12 February, as a national day of mourning. The Minister of Labour and Social Affairs, Maxim Topilin, announced that each victim's family would receive compensation amounting to 2 million rubles (approximately US$35,000). Following the tragedy, President Vladimir Putin cancelled his scheduled visit to Sochi and committed to overseeing the special commission formed to investigate the incident.

On 12 February, Saratov Airlines halted all operations involving An-148 aircraft, in addition to suspending all flights to Orsk. Subsequently, the airline resumed An-148 services on 16 February after conducting thorough technical inspections on its entire An-148 fleet. However, on 20 March, the Federal Service for Supervision of Transport (Rostransnadzor) suspended all Saratov Airlines flights due to further regulatory breaches. Ultimately, on 1 June 2018, Saratov Airlines had its air operator's certificate revoked as a result of these violations.
