Russia's certification authority has approved the ATR 42-600 and 72-600 for operations in its airspace and in the Community of Independent States (CIS).
The approval by the Interstate Aviation Committee clears both turboprop types to be candidates for orders from Russian airlines.
"We are convinced that this certification will open up new commercial and operational perspectives for ATR-600 series aircraft in Russia and CIS markets," says Carmine Orsi, senior vice president of engineering for ATR.
The move follows similar approval granted in Russia in June for the Bombardier Q400, which competes with the ATR 72-600.
Russia is expected to order hundreds of turboprops over the next 20 years and locally-built alternatives, such as the Ilyushin Il-114, have struggled to gain market share.
