Rostransnadzor, which is the transport supervising authority of Russia, has banned Aero Rent, Tatarstan, Atlant-Soyuz, Aviacon Zitotrans, Center Avia, Gazpromavia, Lukoil, Russkoe Nebo, and UTair from executing charter and one-off flights to the EU. The reason for the ban is the notice from the Transport Directorate of the European Commission which stated that the said airlines were guilty of repeated violations. The airlines did not check their aircraft and they concealed the violations from the Russian transport authority. Rostransnadzor has taken the step to safeguard the reputation of Russia as an established air power.
