Russian airline Grozny-Avia could receive its first Sukhoi Superjet 100 in December.
A source at the airframer's civil division says it is thrashing out financial arrangements for the deal with the government of Chechnya, which owns the carrier.
He suggests that a baseline Superjet 100 could be handed over to Grozny-Avia next month if the two sides conclude a lease agreement.
It would then become a fifth domestic operator of the regional type after Aeroflot, Yakutia Airlines, Moskovia and Gazpromavia.
In August, the carrier expressed willingness to place an order for eight Superjets, including a VIP variant.
