The reasons for frequent accidents involving Russian aircraft may lie not only in the mistakes of pilots or air traffic controllers. According to the Research Institute of Civil Aviation of the Russian Federation, counterfeit spare parts are increasingly found on aircraft (today there are about 7%). Only now the departments responsible for flight safety become more active only after “the thunder roars.” After the crash of the Tu-154 near Donetsk, the Prosecutor General’s Office and the Ministry of Transport identified numerous violations within airlines and the enterprises serving them and shortcomings in control over them.
