Investigation of the MI-823 helicopter crash in Almaty Oblast has been completed, Tengrinews reports citing the Chief Transport Prosecutor's Office.
The tragic accident involving the MI-823 helicopter took place in autumn 2012 and claimed 8 lives. The helicopter owned by Zhezkazgan branch of Euro-Asia Air company was contracted by a Kazakhstan-Chinese pipeline company to fly over Atassu-Alashankou oil pipeline.
"The investigation found that the air accident happened amid complicated weather conditions and lack of sufficient visibility. The Commission for Air Accidents Investigation of the Transport and Communication Ministry of Kazakhstan confirms this in the conclusions of its final report," the Prosecutor's Office said.
The pilot in command was the one who made the decision to take off in spite of the negative weather information. While piloting the helicopter amid the complex weather conditions he inadvertently lost control of the aircraft attitude when switching from visual controlled flight to instrumented flight and violating the flight rules in the process. He lost control of the helicopter and the MI-8 crashed.
"The conclusions are based on a comprehensive analysis of conversations of the pilots, decoded records of the flight data acquisition unit and other evidences supported by the investigation carried out by aviation experts. Other versions of the accident that were initially considered - technical failure, shortage of fuel, mistakes of flight operations officer or meteorological services, explosion or fire onboard - were dismissed as a result of the investigation," the Chief Transport Prosecutor's Office said.
The helicopter with 8 people onboard went missing in the area of Koktuma-Dostyk next to Kazakhstan-Chinese border on November 24, 2012 and it was discovered only on November 29. According to Kazakhstan Emergency Situations Ministry, the wreckage of the helicopter was found in the area of the 16th Railroad Junction.
