Tech failure, human error main theories for Tu-154 crash, not terrorism – Russian transport minister

According to Sokolov, a “technical problem or piloting error” could have led to the disaster.

“Today, the main theories do not include terrorism, so we assume that either technical problems or a piloting error may have been the cause. But I stress that only an investigation, along with a special technical Ministry of Defense committee will tell us for sure,” the minister said at a briefing.

The search operation has been stepped up, with more ships, divers, and aircraft arriving on the scene.

Forty-five vessels and five helicopters, as well as drones, are now involved in the search operation, according to the latest information from the Russian Defense Ministry.

The search zone around the crash site has been expanded, the Emergency Ministry said.

The flight recorders of the crashed Tu-154 haven't been recovered yet, the head of Russia's Emergency Ministry, Vladimir Puchkov, told TASS.

The Tu-154 was initially supposed to refuel in the city of Mozdok in North Ossetia, but due to bad weather the plane was redirected to the airport in Adler, a Black Sea resort, “therefore, nobody knew beforehand that the plane would refuel at the airport in Sochi,” a security source told TASS.
After arriving in Adler, “only two border guards and one customs officer came onboard, and only one navigator shortly left the plane to control refueling,” the source added.
