The Antonov 148, registration RA-61704, reportedly collided with a helicopter at around 6000 feet. However reporting on the crash appears to be inferred from video and has not been confirmed.
The plane had taken off from runway 14R. Then 5 to 6 minutes later it crashed about “14nm northeast of the aerodrome in the Ramensky District.” The aircraft was falling as fast as 22,000 feet per minute just prior to when it stopped broadcasting its location.
Already 50 bodies have been recovered from the wreckage which was “distributed over a distance of about 1000m.” No one is believed to have survived.
A helicopter was said to have been found near the crash site as well. Of course much initial reporting in the immediate aftermath of a crash can turn out to be incorrect, especially as to its cause. However the wide area of debris could at least be consistent with the aircraft breaking up prior to impact with the ground.
Here’s video from the crash scene.
Saratov Airlines has been around since 1931 and had been part of Aeroflot. It operated as Saravia until 2013. The carrier had the ability to operate international flights revoked in 2015 after a surprise inspection found individuals other than pilots in the cockpit of a flight, but they were permitted to resume international charters in mid-2016. In addition to domestic service they operate to Armenia and Georgia.
