United Aircraft is not ruling out a stretched version of the Sukhoi Superjet in the future - but says it has to win a customer for the variant before development can proceed.
"We will decide when we get a customer," says UAC president Mikhail Pogosyan, adding: "Time will tell."
Mexican low-cost carrier Interjet took delivery of its first Superjet 100, configured with 93 seats, in a ceremony at the Paris air show yesterday. Russian lessor Ilyushin Finance signed a tentative deal to order 20 SSJ100s at the show, and Bahrain leasing company AeroLease has signed a letter of intent for financing or leasing of "existing and prospective deals" for the SSJ100.
UAC says today the number of aircraft under the AeroLease deal will be announced by year-end, but it will likely be "fewer than 10 aircraft initially".
In the meantime, Sukhoi hopes to certify the long-range version of the Superjet "shortly", says Pogosyan. Flight testing of the long-range version began earlier this year.
UAC subsidiary Irkut is also developing the MC-21 narrowbody, which is scheduled for first flight in 2015 and entry into service in 2017. The programme is on schedule, says Pogosyan, noting that there is an order backlog of more than 130 aircraft.
"We will expand that backlog after first flight in 2015," he says.
