A Saratov Airlines Antonov An-148 crashed yesterday afternoon near Moscow killing 71 passengers and crew.
Russian investigators are looking into why the aircraft came down just 10 minutes after taking off from Domodedovo Airport.
Early reports indicate that weather conditions, human error or technical failure were possible reasons for the accident.
The eight-year-old aircraft was heading for Orsk in the Ural Mountains before it crashed near the village of Argunovo, about 80km (50 miles) south-east of Moscow.
The incident was the first commercial passenger aircraft crash for more than a year. 2017 was the safest year on record for the commercial air travel industry.
Saratov Airlines was banned in 2015 from operating international flights, but the carrier appealed before resuming international charter services in 2016 after changing a policy.
The airline flies to a number of domestic locations in Russia from its base in Saratov and to Armenia and Georgia.
