"We are expecting to sign another two contracts for 24 planes," Vladimir Prisyazhnyuk said at an international aviation seminar.
Prisyazhnyuk said the total volume of confirmed orders for the SuperJet 100 will approach 100.
The first flight of SuperJet 100 is scheduled for fall 2007, and static tests are underway now.
Sukhoi said March 20 it will start supplying SuperJet 100 aircraft to the country's largest air carrier Aeroflot [RTS: AFLT] by late 2008.
Earlier, it was reported that Aeroflot was planning to buy 50 of the aircraft.
The Sukhoi SuperJet-100 belongs to a series of RRJ (Russian Regional Jet)-type planes, with a seating capacity of 60 to 95, which is being developed by Sukhoi, NPO Saturn, Snecma and Boeing.
The RRJ market is estimated at 5,400-5,600 until 2023, which amounts to around $100 billion in sales. Sukhoi plans to make at least 700 SuperJet-100 planes, with the first six planes due later this year.
According to forecasts, 35% of the aircraft could be sold in North America, 25% in Europe, 10% in Latin America, and 7% in Russia and China.
