Most Russian civil aviation airplanes are registered in Bermuda. The news below means they forbidden from flying anywhere outside Russia. And since every airplane in the country cannot be maintained because the parts are foreign... They really should not be flown inside the country either.
=========================================
The Bermuda Civil Aviation Authority [BCAA] has “provisionally suspended all Certificates of Airworthiness” of the aircraft operating under the “agreement between Bermuda and the Russian Federation.”
A spokesperson said, “International sanctions on the aviation sector have had a significant impact on the ability to sustain safety oversight on Russian operated aircraft on the Bermuda Aircraft Registry.
“The airworthiness system has been restricted to the point that the Bermuda Civil Aviation Authority [BCAA] is unable to confidently approve these aircraft as being airworthy.
“Therefore, as of 23:59 UTC on March 12th 2022, the BCAA has provisionally suspended all Certificates of Airworthiness of those aircraft operating under the Article 83bis Agreement between Bermuda and the Russian Federation.
