Among 49, six were crew members. No survivors were found.

The Antonov An-24 passenger plane crashed in the eastern Amur region.

The 43 passengers include five children.

The debris of the crashed plane was tracked by a rescue helicopter on the mountain side.

The plane went missing after it dropped off radar screens while approaching its destination, a remote town of Tynda bordering China.

"According to the director of Tynda Airport, the plane caught fire upon impact, and a Mi-8 helicopter crew flying over the area reported no signs of survivors," the regional civil defence and fire safety center told Russian news agency TASS.
