Mi-171A3 Helicopter Successfully Tested in Yakutia’s Extreme Cold
Mi-171A3 helicopter passes extreme cold tests in Yakutia at −50°C. Results sent to Rosaviatsiya confirm stable systems and safe operation in harsh climates.
The Mi-171A3 helicopter has undergone an additional round of testing in the severe cold of Yakutia, according to the state corporation Rostec.
The trials were carried out by Russian Helicopters, a holding within Rostec. Engineers focused on the import-substituted version of the aircraft, subjecting it to flights in temperatures as low as −50°C. Operating in such conditions made it possible to assess how the machine performs in one of the harshest climates on Earth.
Test results have already been submitted to Rosaviatsiya, where they will be used to refine certification documentation. Specialists confirmed that the helicopter’s systems remain stable, and that the aircraft can safely take off and land even in extreme cold.
The program included 66 flights along with 22 ground runs. Rostec noted that exercises of this kind serve not only to verify declared specifications but also to extend the permissible operating temperature range.
The Mi-171A3 is designed as a multipurpose helicopter. It can transport cargo and passengers, operate offshore, carry out search-and-rescue missions, and service drilling platforms. The aircraft is equipped with an emergency flotation system and a reinforced fuselage built to improve survivability in аварийных situations.
In March, the helicopter received certification in its import-substituted configuration. At the same time, its setup for flights over vast water areas was approved.
