Russia has launched an investigation into the plane crash that killed Total CEO Christophe de Margerie on Monday night.
The private jet hit a snow plow as it was taking off, killing all four people on board.
The airport said visibility was low at the time of the crash.
A French delegation has arrived to help with the investigation, such as translating black box recordings and providing technical data on the aircraft.
De Margerie was a strong opponent of Western economic sanctions against Russia over its actions in Ukraine.
He'd been at a meeting with foreign overseas executives at the country home of the Russian Prime Minister Dmitry Medvedev on the day of the crash.
