Air ambulance on a mission to help three persons that were lost in the mountains. The helicopter had to wait in heavy snow showers while boarding the passengers. The crew were aware of a power line they had to be careful to avoid while navigating out of the valley. Due to the heavy snow the crew had issues locating the power line. As they were searching for the power line one of the engines suddenly stopped. The crew immediately landed safely, and shortly after landing the other engine also stopped. Nobody was injured in the incident.
Helicopter had to be airlifted out due to location.
