Russian investigators have confirmed that audio from the cockpit voice recorders onboard flydubai flight FZ981 which fatally crashed two weeks ago will not be made public.
The Russian Interstate Aviation Committee said that – in accordance with international and Russian air accident investigation policy – the CVR data is considered as “non-public disclosure information.”
The announcement comes after a Russian TV station broadcast what it claimed were the final words of the flight crew aboard the Boeing 737 aircraft which crashed in Rostov on Don on March 19. The accident left all the 62 onboard dead.
“The IAC has not disclosed and has no intention to disclose this data,” it said on its website.
“The work on the transcript of the flight crew conversation is going on. Today we have more than one hour of flight crew conversations transcribed, including the final stage conversations. Experts from the United Arab Emirates, Russia, the United States and France are involved in this job in the IAC laboratory,” it added.
The IAC also confirmed that data analysis of the onboard recorders has proved that there were no failures of the aircraft systems, the components or the power plant.
The aircraft had a valid airworthiness certificate, received all the necessary maintenance and was in working order before the last departure.
The Boeing company has also been requested to provide the technical documentation for the evaluation of the aircraft systems performance and information related to Boeing aircraft events with similar scenarios.
Meanwhile aircraft fragments identification and layout works are ongoing at the Rostov Civil Aviation Factory N412 facilities.
Experts are working on the data preparation for the “mathematical model analysis and for the aircraft flight trajectory” based on the audio and video reconstruction of the flight.
“The detailed analysis of all factors related to the aircraft operation is going on. The investigation team plans to conduct necessary examinations of the aircraft control system recovered components and elements,” the IAC said.
