After performing three test flights, this MS-21 got to the airfield in Zhukovsky, where the Yakovlev complex does not continue certification work at the base. In addition, fine-tuning and debugging of all system aircraft will be carried out and, as Rostec plans, the MS-21, equipped with intensive engines, will complete certification by the end of the year.
According to UEC General Designer Yuri Shmotin, the PD-14 engine is a switch in the entire domestic engine building industry, and the replacement of foreign engines with PD-14 by MS-21 has become a good compatibility for the entire Russian aviation industry.
Recall that the MS-21 is a medium-haul passenger aircraft, expected, depending on the modification, to carry from 160 to 210 passengers, at the end of 2021 received a basic level type certificate and made its first flight with transverse and composite wings.
