Russian energy giant Gazpromavia is to sign for 10 Sukhoi Superjet 100 aircraft.
A source familiar with the situation told Flightglobal at the MAKS Moscow air show that the company would reach a deal for the twinjets during the event.
Gazpromavia operates services on a network largely connected with supporting the country's oil and gas industry.
Its fleet includes a mix of Western and Soviet-built types.
Indonesia's Sky Aviation signed an agreement firming its order for 12 Superjets at MAKS.
