Russian airframer Irkut has shortlisted Pratt & Whitney and Rolls-Royce to supply engines for the export version of the propsed MS-21 twin-jet.
Speaking at the Moscow MAKS air show, Irkut's president Oleg Demchenko said the tender committee planned to choose between the two Western engine manufacturers by the end of this year.
He adds: "Selection of the powerplant is the most important of all the tenders we've invited. We need to scrutinise several technical issues before making it."
To qualify for submitting a bid and stand a higher chance of winning the MS-21 tenders, foreign manufacturers are requested to have a Russian-registered partner.
Sources at Irkut say Pratt & Whitney is looking to team with engine developer Aviadvigatel and affiliated plant Perm Motors, while Rolls-Royce would link with Moscow-based engine specialist Salyut.
