Russia’s war in Ukraine is hitting the aircraft leasing industry hard, upending the internationally agreed-upon norms of aircraft financing.Russian airlines lease around 500 aircraft from foreign companies. A law signed this week by Russian president Vladimir Putin allows these carriers to continue to operate these aircraft on domestic flights, even after the lessors cancel the leases, according to the state-owned TASS news agency.It’s a repudiation of foreign-owned debt — and the rule of law, said aviation consultant and former airline executive Robert Mann.Want more airline-specific news?

A combination of sanctions and unilateral actions by Boeing, Airbus and engine manufacturers mean that Russia is now cut off from receiving the parts and service support necessary to maintain its fleet of nationalized aircraft. This means that everything from hydraulic pumps to aeronautical charts provided by a company called Jeppesen, which is owned by Boeing, are now off-limits.“Airplanes will be grounded as no additional parts are available to fix them,” Mann said, adding that some aircraft are likely to be permanently parked and raided for spare parts. On the parts front, it will possibly be a situation similar to that of Iran, which was cut off from Western supply chains following the 1979 Iranian Revolution yet was able to maintain an airline industry and a fleet of western aircraft.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

Nearly 75% of Russian-operated aircraft were registered in Bermuda, according to the aviation consulting firm IBA, and that nation has now suspended those registrations over safety concerns. Russian operators are now dual-registering those aircraft in Russia, something that the International Civil Aviation Organization, the United Nations’ aviation body, says is inconsistent with its core principles due to ambiguity about safety oversight.“Again, that’s, that’s kind of part and parcel of the walking away from the rule of law,” Mann said. “It’s walking away from the rule of oversight in that particular case.“Traditionally, aircraft lessors and financiers would look at financial risk as the primary component of their due diligence conducted as part of a leasing deal. Russia’s actions might change that going forward — especially for deals being done with airlines that operate in autocratic countries, Mann said.“Now you have a much bigger issue and that is the due diligence on sovereign risk and literally the rule of law,” he said. “If you give operational custody of an asset to someone who would then just … steal it, that’s the sort of risk that no one has really ever had to consider. Why would you even consider doing business in a situation like that?“Featured photo by Leonid Faerberg/SOPA Images/LightRocket via Getty Images.
