Russia's Moskovia Airlines has placed a tentative order for five Sukhoi Superjet 100s.
The letter of intent, signed on 19 August at the MAKS air show, outlines the supply of three baseline 95-seat Superjets with an option for a further two.
Delivery is tentatively scheduled to begin in 2013, said the carrier. It operates two leased Boeing 737-700s and two 737-800s, as well as three Antonov An-12 freighters.
Last month Moskovia narrowly escaped losing its air operator's certificate after air transport agency Rosaviatsia expressed concerns over its financial position.
