Number of Russian/Soviet planes on Russian commercial flights has been close to zero for quite a long time because of exploitation costs, lack of large scale production in post-Soviet times, tightened international standards, etc. It was easier to make money by leasing foreign planes, so civil aviation industry went poof. It is unlikely that parts of old Soviet planes could used in Boeings and Airbuses.
