Russian Helicopters’ Mi-171A2 can be flown in temperatures as low as -58 deg F. The manufacturer said Tuesday the aircraft proved that capability during tests in Yakutia, located in the eastern of the country.

The test involved two helicopters, eight ground runs and 36 flights, according to Russian Helicopters. During testing, the temperature dropped to -76 deg F, and the manufacturer said all systems and onboard equipment functioned properly.

"The helicopters of the Mi-8/17 family deserve the reputation of unpretentious and efficient machines that are not afraid of harsh conditions,” said Andrei Boginsky, general director of Russian Helicopters. “Therefore, the confirmation of the possibility of using the Mi-171A2 at ultra-low temperatures was quite expected.”

Participating in the tests was Gosnii GA, a research institute based in Moscow. Those specialists noted, according to Russian Helicopters, the short preparation time the aircraft required ahead of flight, convenience of maintenance, the reliable operation of the digital flight control and navigation system, and the performance of other systems.

"The Mi-171A2 is one of the most anticipated Russian helicopter engines, and the first four helicopters are scheduled for delivery this year, and I expect that the order book for this car will grow in the near future," said Russian Minister of Industry and Trade Denis Manturov. "There is interest in the helicopter both in Russia and abroad.”

More than 80 changes were made to develop the Mi-171A2 from the Mi-8/17 family, the manufacturer said. Notably, the Mi-171A2 features a new carrier system and new rotor, among others.

The Mi-171A2 received a Type A certificate from the Russian Federal Air Transport Agency in August 2017.
