Last December 2020 the MС-21-310 aircraft equipped with the new Russian PD-14 engines made its maiden flight from the airfield of Irkutsk Aviation Plant.

The aircraft was operated by the crew of test pilots Vasily Sevastyanov and Andrey Voropaev and test engineer Alexander Solovyev. The flight task included checks of power plant operation modes, aircraft stability and controllability, as well as the operation of its systems. 

The flight time was 1 hour and 25 minutes, altitude up to 3500 m and speed up to 450 km/hour.

The MC-21-300/310 is a new generation medium-range passenger airliner, which is being developed by Irkut Corporation (part of United Aircraft Corporation). The MC-21-300 program is at the stage of certification testing and launching commercial production of  MC-21-300 aircraft. 

The PD-14 engine has been created by a broad cooperation of the UEC enterprises and the industry science using the state-of-the-art technologies and materials. It is the first fully Russian turbofan engine for civil aviation since the early 1990s.

The engine thrust at takeoff mode is 14 t, dry mass is 2,870 kg, fan diameter is 1,900 mm. Due to innovative technologies and materials, specific fuel consumption is 10-15% lower than of the previous generation engines.
