The Superjet 100 project is a family of medium-haul passenger aircraft developed by Sukhoi in cooperation with U.S. and European aviation corporations, including Boeing, Snecma, Thales, Messier Dowty, Liebherr Aerospace and Honeywell.
Viktor Subbotin said a total of 30 airplanes were to be supplied to Aeroflot. The company had initially been scheduled to deliver the first plane in November 2008.
He said the next consignment of Superjet 100s would be provided to the Rosavia airline, a successor to the now defunct AiRUnion.
The plane manufacturer earlier said the first Superjet 100 aircraft had made 40 test flights, clocking a total of 100 hours, and that a total of four planes would take part in the certification program, which should be completed in the third quarter of 2009.
Sukhoi earlier said there were at least 100 orders for the aircraft.
Sukhoi, part of the United Aircraft Corporation (UAC), plans to manufacture at least 700 Superjet 100s, and intends to sell 35% of them to North America, 25% to Europe, 10% to Latin America, and 7% to Russia and China.
