Poor air history

UTair boasts three ATR-72 aircraft manufactured by the Franco-Italian manufacturer ATR, according to the website of the airline (www.utair.ru).

ATR is an egalitarian society between the two main companies of aeronautics in Europe, Alenia Aermacchi – a Finmeccanica company and EADS.

The accident is the worst air disaster in Russia as a Yak-42 plane crashed on the shore of a river near the city of Yaroslavl after takeoff on September 7, 2011, killing 44 people, which included members of the ice hockey team Lokomotiv Yaroslavl.

The Russian President, Dmitry Medvedev, called for a reduction in the number of Russian airlines and improvements in the training of the crew after this tragedy, which followed a crash in June with 47 dead, among them a sailor who had been drinking.

The International Association of air transport (IATA), said in December that global rates of air safety had improved in 2011, but in Russia and in the Commonwealth of independent States – which links former Soviet republics – had worsened. The Vice-President of IATA, Günther Matschnigg, security was a key problem in Russia that pilots and technicians of Earth are having to adapt to increasingly sophisticated planes.

Matschnigg said that Russian Aviation and political leaders have admitted that it should improve the training of pilots.
