Russian plane producer Irkut plans to swap Pratt & Whitney engines for Russian-made Aviadvigatel PD-14 engines on an MC-21-300 jet. Irkut is reportedly planning take a look at flights of the plane with the brand new engines fitted. The transfer comes greater than six months after the US and European nations imposed sanctions on Russia that forestall its airways from accessing plane, engines, and spare components made in these nations.

In keeping with FlightGlobal, the six-year-old MC-21-300 registered as 73051 and used as a testbed by Irkut was fitted initially with US-made Pratt & Whitney PW1400G engines. However Russian state know-how agency Rostec has indicated Irkut will quickly take a look at the airplane with Russian-made engines.


Irkut has an extended historical past with Pratt & Whitney. In 2019, they ordered 40 PW1400G engines for his or her MC-21 plane program. Deliveries had been slated to start and run by to 2023. Earlier this 12 months, US-imposed sanctions on Russia in response to its invasion of Ukraine stopped deliveries. Pratt & Whitney had deliberate to ship 20 of the engines this 12 months.

Nevertheless, Pratt & Whitney’s loss is probably Rostec’s achieve. The Aviadvigatel PD-14 is the primary turbofan jet engine created in fashionable Russia. There are excessive hopes for the product because it prepares to hit the skies with the Irkut MC-21 this decade. Floor testing started 9 years in the past earlier than flight assessments began in 2015.

To this point, one other Irkut testbed plane registered as 73055 has operated round 100 flights utilizing the PD-14 engines. All up, 73055 and 73051 will function almost 250 flights utilizing the Rostec-made engines all through the certification course of. Rostec Deputy Basic Director Vladimir Artyakov says the certification course of is “continuing in keeping with plan.”

Just like the PD-14 engines, the mid-range MC-21-300 plane program is a piece in progress that dates again over a decade. The plane has been making take a look at flights since 2017, however the plane kind is but to enter service with industrial passenger airways. Sadly for Irkut and the Russian Authorities’s push in the direction of sovereign plane manufacturing capabilities, between 40% and 50% of the MC-21-300 jet’s equipped parts are imported, and sanctions imply many scheduled deliveries are usually not forthcoming.

Irkut says they’ve discovered various suppliers for a lot of components from sources in China, India, Brazil, and the Gulf states. Nevertheless, sanctions-related delays are inflicting additional blowouts within the MC-21-300 program. The swapping of the Pratt & Whitney engines for Russian-made Aviadvigatel PD-14 engines is simply one other time-consuming complexity on this story.
