Investigators on Monday began examining the Russian passenger plane's black box, which contains the plane's flight data.
The aircraft crashed near Moscow minutes after taking off. All 71 people on board the plane died.
The Antonov AN-148 plane went down in a snow-covered field,which has made it difficult for emergency workers to access. They were forced to try and reach the wreckage by foot or on snowmobiles.
Rescuers went through deep snow in the search for body parts and debris after the disaster - which counts as the country's deadliest air crash since 2016.
The Russian Aviation Committee said the plane's black box was recovered on Monday.
It added that about 400 pieces of the plane have also been found, so far.
