Mack believes that the helicopter fell due to the incorrect decision of the commander to continue the flight with a deterioration in visibility and the difficulty of visual orientation. And also because of the untimely decision on the return to the visibility zone, the lack of sufficient flight skills in the devices and the unpreparedness of the pilot to the transition from visual to instrument flight.

According to the investigation, a conclusion was concluded that there was no sufficient visibility in the gorge where the plan of the intended landing was located. The helicopter was in good condition and was refueling by conditioning fuel in a volume sufficient for flight. Finding the site and performing a safe landing was problematic, there was a surface from stone blocks around.
