The Civil Aviation Administration of China (CAAC) has issued a national type certificate for the Mi-171 equipped with VK-2500-03 engines, clearing the path for Russian Helicopters to sell the helicopter in China. The VK-2500-03 engine is more powerful than the previously stock TV3-117VM powerplant in part due to improved design, including the incorporation of heat-resistant materials, BARK-78 digital automatic controls, and an emergency power mode for one engine inoperative (OEI) operations. This combination gives the Mi-171 a higher load capacity and service ceiling.
