The Tu-154 crashed in eastern Ukraine en route from the Russian Black Sea resort of Anapa to St. Petersburg. All 170 people on board, including 45 children, were killed.
"Expert examination will be conducted in Donetsk, where all the necessary equipment is available and where [Russian] experts from Rostov-on-Don have arrived," said Igor Levitin, who heads a government commission investigating the crash.
He said the bodies will be transported to Russia by Pulkovo Airlines, a St. Petersburg-based company that operated the crashed Tu-154.
He also said that one Dutchman was on board the plane, according to preliminary data.
More than 200 relatives of the victims are expected to arrive at the crash site outside Donetsk.
Levitin said flight recorders found at the crash site seemed to be in satisfactory condition and would be sent to Moscow for Russian and Ukrainian experts to decode.
Preliminary reports suggest the plane could have been hit by lightning.
