Following the Full-Scale Russian Invasion of Ukraine, the West imposed crippling sanctions on the Russian aviation industry. Russia moved quickly to seize hundreds of Western-owned airliners before the foreign-leased aircraft could be taken out of the country (Russia has since been buying the jets). But now Russia remains cut off from Western support and Western parts for its Airbus and Boeing airliner fleets. However, it has now been reported that engineers from the Russian S7 Airline are reverse-engineering the engines on Boeing 737s and Airbus A320s.
