The Tu-154 plane, carrying 92 people, all presumed dead, was headed to Russia's air base in Syria when it disappeared from radar following takeoff from Sochi, reports said.
Wreckage from the trijet's fuselage has been located at a depth of 70m (230ft) some 1.5km from the Sochi coast, says the Russian ministry of defence.
Officials do not believe the plane crash was caused by an act of terrorism, according to Viktor Ozerov, head of the defense affairs committee at the upper house of Russian parliament, AP reported.
Russia's RIA news agency, citing an unidentified security source, said preliminary data indicated that the plane had crashed because of a technical malfunction or a pilot error.
Syrian President Bashar al-Assad said on Sunday he was "saddened" by the crash.
