Russian flag carrier Aeroflot has formally taken delivery of its first Sukhoi Superjet 100 regional jet.
The airline on 6 June signed a protocol of aircraft technical acceptance from the manufacturer and applied to register it with regulators.
It is expected to put the aircraft into revenue service between Moscow and St Petersburg on 16 June, ahead of the annual international economic forum in St Petersburg.
Aeroflot will become the second operator of the Superjet 100 after Armenian carrier Armavia, which has been operating the first serially-produced example of the type since 19 April.
Under the delivery schedule agreed with Sukhoi, Aeroflot is to receive 10 Superjets this year, a dozen in 2012 and eight in 2013.
