Russian investigators have retrieved the cockpit-voice recorder of the crashed Dagestan Airline Tupolev Tu-154M in Moscow, nearly a week after the accident.
The Interstate Aviation Committee (MAK) recovered two of the three recorders almost immediately after the 4 December crash at Domodedovo Airport.
But it was unable to locate the MARS-BM audio recorder at the time.
MAK says today, however, that the device has been located at the site of the crash and that it will be transferred to its analysis laboratory.
"Specialists from MAK will give an assessment of its condition and open its container," says the organisation.
Investigators are trying to understand why two of the aircraft's three engines failed as it climbed out of Moscow Vnukovo during a flight to Dagestan.
With the third engine also performing poorly, and threatening to fail, crew members opted to attempt a landing at Domodedovo. The aircraft landed long on the runway, striking the ground hard, overran and broke up.
Two of the occupants on board the Tu-154 were killed in the crash.
