Investigation Summary
On January 9, 2009, a Mil Mi-171 helicopter carrying several high-profile Russian officials disappeared in the Altai Republic near the Mongolian border. A large-scale search operation located the wreckage two days later on a steep mountain slope. The crash site was littered with the carcasses of argali, a near-threatened species of wild sheep listed in the Red Data Book of the Russian Federation. Among the fatalities was Aleksandr Kosopkin, the Plenipotentiary Representative of the Russian President in the State Duma. The presence of the carcasses and firearms at the site immediately led to allegations of illegal poaching. The Interstate Aviation Committee (MAC) investigation revealed that the crew had descended to extremely low altitudes to facilitate the hunt. Crucially, at the time of the accident, an unauthorized passenger—who was a pilot of a different Mi-8 helicopter—was occupying the right pilot seat, while the staff co-pilot was in the cabin. While maneuvering to track the animals at approximately 3,000 meters, the helicopter struck the mountain terrain during an attempt to perform a hovering maneuver. The scandal deepened when it was revealed that the flight had been organized for VIP recreation, bypassing standard flight safety protocols and environmental laws.
Final Conclusions
The Interstate Aviation Committee (MAC) published its final report on June 12, 2009. The investigation concluded that the primary cause of the accident was the crew's decision to perform unauthorized low-altitude maneuvering for the purpose of hunting. This led to a collision with the mountain slope. The report confirmed that shooting from the helicopter at low altitudes was the direct catalyst for the crash. Following the aviation findings, a criminal investigation into poaching was initiated on April 21, 2009, after significant public pressure from conservation groups like WWF Russia and Greenpeace.
