A medevac helicopter operated by Air Transport Europe crashed in the mountains of Slovenský raj. The helicopter was on it's way to a ten year old boy who suffered a head injury.
It impacted powerlines and crashed in a ravine.
Cause of accident
The main and immediate cause of the accident was the collision of the helicopter with steel power lines hanging over the Hornád canyon, during a flight in low height;
The approach and start of technical intervention were performed by the helicopter crew under meteorological conditions negatively affected by the sunset, which probably caused the overlooking of electric power lines by the pilot flying against the light.
Contributory factors
Rescue flight in a difficult mountain terrain under specific conditions;
Non-marked electric power lines from the view of the helicopter crew;
Installation of electric power lines on low pylons blending with surrounding forest stand, which rendered its identification difficult.
High probability of blinding by the sun disappearing below the horizon in opposition to the main task to find the place for airdrop of the rescuer in a dark valley without contrasts.
Low discernibility of objects in a dark valley and resulting difficult identification of power line conductors
