On a different note, here's the follow up video of the last video about the Russian air industry that I posted:
TL;DW: A couple weeks back Putin signed a law letting Russian airliners re-register their leased aircraft in Russia. Effectively allowing Russian airliners to steal their leased planes and get new airworthiness certificates and insurance from Russia instead of international companies that can be forced to revoke them by sanctions. Bermuda and Ireland most effected. Russian airliners next problem is going to maintenance. There's a bit more detail about maintenance, but the short of it is that regular maintenance requires regularly replacing parts that have received a certain amount of wear to ensure safety. Russia can no longer buy spare parts due to the sanctions. Beyond the obvious problem, its a problem for those airworthiness certificates, which to meet international standards requires using certified parts that they can track from manufacturer to aircraft if a problem is discovered.
Theoretically Russia can just manufacture it's own replacement parts for western built planes, but that'll kill the value of the planes as using uncertified parts means that their proper maintenance can no longer be assured. Their first alternative would be ground the western planes they don't need and use them for parts for the remainder; then once the war ends and they can buy parts again, they can buy parts for the planes they cannibalized. But that'll only hold them for a few months to several months before they start running out of some items.
Their next option for western planes would be to buy parts through a country that they're still on good terms with. Such a country would be risking themselves being slapped with a ban on being sold aircraft parts. Russia's apparently already attempting this option. Some government official by the name of Valery Kudinov said
China had already told them "no", and they were in talk with Turkey and India. He was
promptly fired for revealing that.
Their final option would be to turn to Russian built aircraft. Unfortunately everything they've got has some key parts that were foreign built. These at least Russia can manufacture replacements for as the plane manufacturer can certify parts for its planes. However the whole process of getting things designed/integrated/certified/manufactured could take months to years.
In short, in a few months Russian aviation authorities are going to have to start choosing between grounding western built aircraft, or compromising on the international safety standards they adopted many years ago. Unless they can convince another country to risk the wrath of the US and serve as a middleman and sell them the parts instead.
