MOSCOW, April 17. /TASS/. The 35 MC-21 Russian passenger jets, Aeroflot air carrier plans to lease in addition to 50 MC-21 jets it ordered earlier, will be equipped with the Russian PD-14 engines, Deputy Industry and Trade Minister Oleg Bocharov told journalists.

"We are still working on all this (contract with Aeroflot - TASS.) These are 35 jets with PD-14 engines," he said.

On Tuesday, Deputy Prime Minister Yury Borisov said that Aeroflot plans to lease 35 MC-21 jets in addition to 50 aircraft it had already ordered.

In February, Borisov said that Russian passenger jet MC-21 can change foreign engines to domestically produced.

The MC-21 jet currently undergoes flight tests with engines by Pratt&Whitney. The Russian engine PD-14 received the type approval at the turn of 2019 and first serial specimen tests are underway.

MC-21 is a medium-haul passenger jet being developed by the United Aircraft Corporation. It may come in two configurations - MC-21-200 (seating 132 to 165) and MC-21-300 (163 to 211). Another configuration, MC-21-400 with up to 250 seats, is also planned.

Currently the MC-21-300 plane is under development. The aircraft performed its maiden flight at the end of May 2017.
