The Russian Federation and Iran have signed an agreement to allow the export of Iranian-made spare parts and other aircraft equipment. Due to sanctions, both countries are currently unable to purchase anything through the regular channels.
The contract should also include maintenance services and technical support. Russia wants to use this to ensure the supply of commercial aircraft built in the West. Iran has many years of experience in procuring and manufacturing spare parts via irregular channels.
It comes as no surprise that the Russian Federation is turning to Iran, which has long been unable to buy on the world market due to US sanctions. You obviously want to make use of the know-how in matters of self-sufficiency. However, machines that are provided with “homemade” spare parts can lose a lot in value.
On the fringes of the agreement mentioned, it was also agreed that the flight frequencies between the two countries should be increased to 35 rotations per week. Currently, Mahan Air, Nordwind Airlines and Aeroflot operate on Russia-Iran traffic. There should no longer be any restrictions on cargo flights in the future.
