Aeroflot is preparing to take delivery of two more Sukhoi Superjet 100s before 2012.
The airline's technical team is conducting a final inspection of the twinjet - registration number 89003 - prior to signing acceptance documents.
The other aircraft is undergoing pre-delivery trials at Sukhoi's assembly plant KnAAPO in Komsomolsk-on-Amur.
The carrier said both Superjet 100s are due to be handed over and deployed on its scheduled routes by year-end.
Since Aeroflot began operating the type's first example on 16 June, its two Superjet 100s have logged a total of 1,226h in service.
Under the delivery schedule agreed with Sukhoi, Aeroflot is to receive 10 Superjets in 2011.
