This could further deteriorate the value of leased western aircraft operating in Russia, as the use of unauthorized Russian spares would render the aircraft not airworthy in western countries.
The Russian aviation authority, Rostaviatsia, has issued developer certificates to five companies that authorize them to perform modification, certification of minor changes, and issuance of technical documentation, including approval of repair documentation and changes. The five companies include the State Civil Aviation Research Institute, S7 Technics, the Ural Civil Aviation plant, Aviation Engineering Solutions, and the Navigator Institute of Aeronautical Instrumentation. This certification will enable them to manufacture Russian spares. However, those spares would not be recognized as airworthy outside Russia.
Currently, India and Turkey are the only two major providers of aircraft spares to Russia, and under the sanctions provisions, Airbus and Boeing are likely to closely examine and restrict those sources of spares as their inventories deplete. As a result, Russia needs to develop its own sources for spares or find that aircraft will be grounded.

Airlineratings.com was developed to provide everyone in the world a one-stop shop for everything related to airlines, formed by a team of aviation editors, who have forensically researched nearly every airline in the world.
Our rating system is rated from one to seven stars on safety – with seven being the highest ranking. Within each airline, you will find the country of origin, airline code, booking URL and seat map information. The rating system takes into account a number of different factors related to audits from aviation’s governing bodies, lead associations as well as the airlines own safety data. Every airline has a safety rating breakdown so you can see exactly how they rate.
Over 230 of the airlines on the site that carry 99 per cent of the world’s passengers have a product rating. Given that low cost, regional and full-service carriers are so different we have constructed a different rating system for each which can be found within each airline.
