Researching (googling) for more information on Embraer's having received certification for the 190 and 195, I stumbled across this surprising August article in Pravda. Russia's Sukhoi Superjet-100 completely hopeless - English pravda.ru
Certification of EMB in Russia is not big problem for SSJ. There are import taxes for EMB to Russia (maybe 20%) and even EMB has higher catalogue price. It is also more easy to get leasing for SSJ then EMB. And many years, most of companies even register foreign planes abroad.
I don't agree with that linked article. There are much inaccuracies and it is not written in objective manner.
The Sukhoi Superjet-100 does not sell abroad.
Aircrafts for Mexico, Laos, Indonesia are already made and will be delivered till the end of this year
The only one jetliner, which was used by Armenian airline Armavia has already been returned to Russia
Now it flies for Armavia and will be sold with the company. In September, only negotiations was done between UAC and Armavia.
etc. etc.
On tomorrow some information of final report should be published.
