The next important stage in the modernization of the Mi-8 was the equipping of it with TV3-117VM high-altitude engines, the first samples of which were tested in 1985. For two years, the Mil Design Bureau created a new basic model Mi-8MTV (Mi-17-1V in the export version), capable of taking off and landing at altitudes up to 4000 m and flying at altitudes up to 6000 m. In addition to ceilings, climb rate, range, etc. .d. The new basic model was distinguished by modern equipment, including a weather radar station and a long-range navigation radio station, had armor, sealed tanks with polyurethane foam filler, bow and stern PKT machine guns, six hanging beam holders and pivot mounts for paratroopers' weapons.

Taking into account the "Afghan" experience, the survivability of parts and assemblies of the helicopter was increased, and for the safety of operation, an emergency splashdown system developed jointly with French companies was installed on the Mi-8MTV. Since 1988, the development of mass production of the Mi-8MTV (Mi-8MTV-1) in Kazan began. The basic model can be used in transport, airborne, air assault, ambulance, ferry versions, as well as in fire support helicopter and mine laying versions.

At the plant in Ulan-Ude, the Mi-8MTV went into production in 1991 with minor changes in equipment under the designation Mi-8AMT (export code - Mi-171). Ulan-Ude helicopter builders have already built several hundred of these machines. In 1997, the Mi-171 in Russia received a type certificate, and two years later - a type certificate in China according to the American FAR-29 standards in passenger and cargo versions for flying over land and water.

Following the Mi-8MTV-1 in the 1990s, the Kazan plant was followed by the basic modifications of the Mi-8MTV-2 and Mi-8MTV-3. Up to 30 paratroopers were placed in their cockpit. These vehicles had reinforced armor and upgraded systems. On the Mi-8MTV-3, only four of the six beam holders remained, but at the same time, the number of possible armament suspension options increased from 8 to 24. The helicopters received a tail rotor with an increased blade chord and increased rigidity of the control wiring, a parachute landing system and an onboard boom with a larger carrying capacity .

Mi-8MTV-3 in 1991 served as a prototype for the export modification of the Mi-172, which was certified in 1994 by the Indian aviation register according to the American FAR-29 standards. All the improvements tested on these modifications were introduced in 1992 on the new Mi-17M demonstration model. In addition, an international navigation system and an improved radar were installed on it, the side doors were enlarged, and the rear cargo hatch was redesigned according to the Mi-26 type (with reduced doors and a descending ramp). A large hatch in the floor made it possible to install an external suspension system with a load capacity of 5 tons.

This demonstration model served as the basis for the creation of the Mi-8MTV-5 (Mi-17MD) in 1997, which is very successful in the international aviation market. Under an agreement with a Canadian company, Kazan helicopter builders are also working on a joint modification of the Mi-17KF. In 1998, modified versions of the Mi-171 and Mi-172 received a domestic type certificate according to the American FAR-29 standards. They were assigned the designations Mi-171A and Mi-172A.

After the collapse of the USSR, the Mi-8 crews continue to perform their difficult military duty in the hot spots of Russia and the CIS. "Eights" were widely used during the conflicts in Nagorno-Karabakh, Abkhazia and Tajikistan. The unique high-altitude characteristics of the Mi-8MTV made them indispensable in high-altitude areas. Only they can provide combat operations at altitudes above 3500-4000 m.

They were widely used during counterterrorist operations in Chechnya. In 1995, several Mi-8 squadrons operated here, which were used mainly for the transfer of personnel, their replacement in positions, the supply of ammunition and food, the removal of the wounded and sick, as well as the evacuation of refugees and the provision of comprehensive humanitarian assistance to the population.
