Russian Federal Air Transport Agency (Rosaviatsiya) attempted to blame weather conditions and the pilot’s response to the Russian emergency airspace closure over the Republic of Chechnya for the Azerbaijan Airlines Embraer 190 passenger aircraft crash in Aktau, Kazakhstan on December 25. A Russian insider source – who is reportedly affiliated with Russian law enforcement and released an alleged transcript of the communications between the crew and a Russian air traffic control in Grozny – accused Yadrov of attempting to conceal the misuse of Russian air defense systems.
