The Superjet 100 project is a family of medium-haul passenger aircraft developed by a leading Russian manufacturer, Sukhoi, in cooperation with U.S. and European aviation corporations, including Boeing, Snecma, Thales, Messier Dowty, Liebherr Aerospace and Honeywell.
"I am very pleased with the results," Sukhoi's CEO Mikhail Pogosyan said.
He said international certification of the plane should be completed in the third quarter of next year.
"We have every chance of completing the certification process in the third quarter of 2009," he said.
Pogosyan previously 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.
The airliner made its first test flights in May and Sukhoi is planning to start Superjet 100 deliveries to clients in the second half of 2009.
Russian government's foreign investment commission recently approved the acquisition of 25% plus one share in Sukhoi Civil Aircraft by Switzerland's World's Wing SA.
Sukhoi, which is 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.
