Description: The MIL Mi-8, dubbed Hip by NATO, is a twin-engine, multi-role, medium transport helicopter capable of transporting troops and equipment or conducting ground attack missions. Besides, the aircraft is also suitable for civilian operators related to a variety of transportation roles. The Mi-8 was developed in the late 1950s and 1960s by the Soviet Union, first flew on July 7, 1961, entering service in 1967. The five-bladed main rotor is driven by either two TV2-117 or TV3-117 turboshaft engines rated from 1,700-shp to 2,200-shp allowing a top speed of 230-250 kilometers per hour. In addition to its crew of two/three men, the standard Mi-8 can transport as many as 24/28 troops. The Mi-17 was the export designation for the Soviet Mi-8. The Mi-171 refers to the modern production standard introduced in 1991. The aircraft design and technologies evolved over 60 years with the current production standards (various models) being far more sophisticated and performant than early models. More than 12,000 Mi-8/17/171 helicopters of all models were produced or are in production for the Soviet Union, Russia and international customers. As of November 2013, roughly 2,400 Mi-8/Mi-17 helicopters remain in service worldwide. In January 2015 that figure had increased to 2,469 aircraft with several models remaining in production beyond 2020.

The Mi-171A1 is a transport helicopter intended for use by civilian operators carrying up to 26 passengers over ranges of 610 kilometers. In addition to the transport role, the Mi-171A1 is suitable for search and rescue (SAR) missions, geological surveying, patrolling, fire-fighting and offshore transportation. The helicopter is powered by two TV3-117VM turboshaft engines rated at 2,200-hp. The Mi-171E variant is fitted with cabin equipment allowing for operations at night and is powered by two VK-2500-03 engines rated at 2,700-hp for operations in hot climates and at high altitude including mountainous terrain. The Mi-171A1/Mi-171E are manufactured at the Ulan-Ude Aviation Plant (UUAP). The civilian Mi-171A1/E leverage designs, technologies and features from the Mi-8AMT, Mi-8MTV-1, Mi-171 and Mi-172 models produced previously.
