From the Wikipedia article
The crash of a Eurocopter AS.350 helicopter in Khanty-Mansi Autonomous Okrug was an aviation accident that occurred on 29 November 2015 seven kilometres from the settlement of Kedrovy in Khanty-Mansi Autonomous Okrug. 4 people were killed in the accident. The helicopter, chartered by Lukoil, was carrying employees of the oil company “RITEK Beloyarskneft”. The helicopter belonged to the airline Skol.
Investigation and cause
Investigation
A criminal case was opened over this event under part 3 of article 263 of the Criminal Code of the Russian Federation. Three versions are being considered: a technical malfunction, a piloting error, and weather conditions. Investigators handed over to the Interstate Aviation Committee a case with the aircraft's logbooks, a portable and a fixed GPS navigator, and the engine control unit. Samples of fuels and lubricants were seized for subsequent expert examination.
The final report on the crash was published on 30 March 2016. According to the results of the investigation, the cause of the accident was the pilot's loss of spatial orientation in conditions of limited visibility and the whiteness of the snow cover, which led to an uncontrolled descent with bank and the collision of the helicopter with the ice-covered surface of a river. A contributing factor was the conduct of the flight under VFR at an altitude below the safe altitude.
