Sukhoi's civil aviation division has delivered the first Superjet 100 to the Russian carrier Yakutia, which becomes the third carrier to take the type.
It flew the twinjet, serial number 95019, to the Siberian company on 18 December. The delivery follows tests and approval to use the aircraft for high-latitude operations.
Yakutia is intending to take two of the type, configured with eight business-class and 85 economy-class seats.
"The aircraft will be put into operation in the near future," says Yakutia general director Ivan Prostit.
He says it will operate routes from Yakutsk to Khabarovsk, Blagoveshchensk, Vladivostok and other cities in the far east of Russia.
Yakutia also plans to use the aircraft on services to Harbin in China, Niahata in Japan, and the Korean capital Seoul.
Sukhoi says it gained supplemental type certification for high-latitude operations - up to 78° north - in November.
"Flight tests proved the proper functioning of the aircraft avionics, most notably the inertial reference system and the satellite navigation systems," it adds.
Yakutia flight crews have been trained at the Moscow Zhukovsky centre of Superjet International. Delivery of the second Superjet will take place in the first quarter of 2013.
