Search teams on Wednesday recovered another flight recorder from a military plane that crashed in the Black Sea, killing all 92 people aboard, the defence ministry said.

The first flight recorder was found the previous day and experts have started analysing its data, seeking to identify the cause of the crash.

The Tu-154 of the Russian defence ministry crashed into the sea early Sunday, two minutes after taking off in good weather from the city of Sochi. It was carrying members of the Alexandrov Ensemble, widely known as the Red Army Choir, to a New Year’s concert at a Russian military base in Syria.

The ministry said 15 bodies and 239 body fragments have been recovered from the crash site. It previously said 17 bodies had been found.

A massive recovery effort has involved 3,600 people, including about 200 navy divers flown to the site from all over Russia. They have been aided by drones and submersibles.

Investigators were looking into whether the crash might have been caused by bad fuel, pilot error, equipment failure or objects stuck in the engines. The top Russian investigative agency said it had taken samples from a fuel tank used to fill the plane, which flew from Moscow’s Chkalovsky military airport and stopped in Sochi for refueling.

The Komsomolskaya Pravda daily and online publication Life.ru published what they described as a script of cockpit conversation, with a pilot yelling about a problem with the plane’s flaps and then shouting: “Commander, we are falling!” It was impossible to verify the report, but both publications were known to have good connections with Russian security agencies.

Flaps are moveable panels mounted on the edge of the wings to increase lift.

The Kommersant daily also said that investigators believed that the crash was caused by a combination of malfunctioning flaps and pilot error, which caused the plane to lose speed and stall.

However, Nikolai Antoshkin, the former deputy chief of the Russian air force, dismissed the claim, saying that responding to flap malfunctions is part of standard pilot training. “If flaps fail to retract or extend in time ... pilots know how to deal with it, it’s not a problem at all,” he said in remarks carried by state RIA Novosti news agency.

Russia’s main domestic security and counter-terrorism agency, the FSB, said it found “no indications or facts pointing at the possibility of a terror attack or an act of sabotage.”

However, some aviation experts have noted that the crew’s failure to report any technical problem and the large area over which fragments of the plane were scattered could point to an explosion on board.

The Tu-154 is a Soviet-built three-engine airliner designed in the late 1960s. Russian airlines decommissioned the noisy, fuel-guzzling aircraft years ago, but the military and other government agencies continue using the plane, which is still loved by crews for its manoeuvrability and sturdiness.

The plane that crashed Sunday was built in 1983 and underwent factory checkups and maintenance in 2014, and earlier this year. Investigators have taken relevant documents from the plant that did the job.
