Experts in Moscow have completed transcribing the communications between air traffic control and the Tu-134 plane that crashed in Russia's northwestern city of Petrozavodsk, crash investigators said on Wednesday.
The RusAir Tu-134 crashed just before midnight on June 20 while attempting to land at Petrozavodsk airport, killing 47 and injuring five people.
Experts from the Moscow-based Interstate Aviation Committee (MAK) have finished restoring the noisy recordings from the black box flight date recorders of the crashed Tu-134 and produced a transcript of the conversation between the pilots and air controllers, with the voices identified, MAK said on its website.
In such circumstances, the committee typically publishes the transcripts as part of its report into a crash.
The experts have ruled out technical failure as the possible cause of Tu-134 crash. In both reports on the circumstances of the crash, MAK said the engines of the Tu-134 passenger jet were operating normally, as were all radar, electronic, lighting and other systems at the airport where the Tu-134 airliner crashed.
Pilot error has been identified as the most likely cause of the tragedy.
President Dmitry Medvedev instructed the government to look into the possibility of early retirement of all Tu-134s. The aircraft entered service in the 1960s and the most recent was built in 1984.
