Official representative of the Russian Ministry for Emergency Situations Victor Beltsov said the bad weather conditions are considered to be the principal cause of the crash. It was due to heavy meteorological conditions that the crew requested for crash landing twice. Bodies of 38 passengers of the Yerevan-Sochi flight have been already found. The rescue works are being impeded by heavy meteorological conditions. The speed of the wind at the site reaches 10-11 meters per second and tends to increase. 23 boats and a deep-diving vehicle "Gnom" that allows to make examinations at the depth of 400 meters are at the site now. A special echo-lead that can fix big objects is also used. According to the Russian MES, the wrecks of the plane lay deep in the sea. Specialists do not rule out that the record boxes won't be found.
