This is reported by the Turkish edition of AirportHaber.
According to the AirportHaber material, refueling and other services are prohibited for private, cargo, commercial and charter aircraft containing more than 25% of American components.
The Bureau of Industry and Security of the U.S. Department of Trade insisted on such measures in a special letter, the Turkish newspaper reports.
The denial of refueling and aircraft maintenance in Istanbul was also confirmed by Kommersant's sources in the two airlines.
Recall, very tough sanctions were imposed on the aviation industry in Russia in 2022: most of the world's countries closed their skies to them, and lessors, mainly from Ireland and Bermuda, demanded that all aircraft be returned to their owners. These aircraft were also stripped of their flight safety certificates. Russia is trying to circumvent the restrictions and is actually starting to pirate the aircraft. They are also hastily re-registering them in their registry. However, this does not deprive them of the impact of sanctions. So, at the moment, Russian airlines can only fly domestically and to a few "friendly" countries, and then only as long as the aircraft are in good technical condition, since foreign companies will not supply them with repairs or spare parts. Leading aircraft manufacturers also joined the sanctions.
At the end of January, it became known that the United States was putting pressure on Turkey to ban Boeing flights to and from Russia and Belarus.
