Strange story..
Local press reported that the aircraft loaded/unloaded in hover and the mainrotor touched a rockwall nearby.
The "flughelfer" Flight assistant managed to jump off and pull one passanger out before the aircraft gained altitude again.
During approach to lodrino heli lost control and rolled over. Flight from collision point at Iragna to homebase Lodrino is only a couple minutes.
Many points are very strange....after the mainrotor hits something else than air its time to land immediately!
