Press releaseIssued by JSC Yakovlev Corporation (Irkutsk Aviation Plant).

On September 13, the second stage of MC-21-300 in-plant development test program began. The modified airplane systems worked without complaint during the flight.

The flight lasted about 2 hours. In the course of preparations for the second stage of MC-21-300 tests, strain gauges have been mounted onto the aircraft. They allow accurate measurement of loads on the structure. Also, by the results of the first flight test stage the software has been corrected.

The main goal of this stage of testing is to extend the range of flights by mass, centering, speed and altitude.
