Council Regulation (EU) 2022/328 prohibits the sale, supply, transfer or export, directly or indirectly, of goods and technology suited for use in aviation, including aircraft, whether or not originating in the EU, to any natural or legal person, entity, or body in Russia or for use in Russia.
The Regulation provides that the period from 26 February to 28 March may be used to wind down existing contracts for the supply of aircraft. That applies to existing lease contracts. Any new leasing contracts would contravene the Regulation.
