Early in June, there were two significant milestones passed by the programme on development of a family of Ilkut MC-21 advanced short/medium-haul passenger aircraft designed to seat 150–210 passengers. Both pertained to the powerplant of the future airliner.

On 5 June 2012, the Irkut corporation, prime contractor for the MC-21 programme, and Pratt & Whitney announced the closure of an agreement on the PW1400G engine for the MC-21 aircraft family. Under the contract, the engine will be the only foreign-made powerplant to fit the MC-21. At the same time, Irkut and Pratt & Whitney selected Short Borthers, a subsidiary of Bombardier Aerospace of Canada, as the sole supplier of engine nacelles for the PW1400G engine family.
