Narrative:
An Agusta-Bell 206B JetRanger III crashed into a wooded hillside near Eggschwand (Reichenbach mun.), Tschäggeten-Alp/Kandertal, Berner Oberland.
All three occupants were killed.

Causes
The accident is attributable to the fact that the helicopter collided with the support cable of goods cableway and subsequently crashed. The cableway was registered in the air navigation obstacle register but unmarked.
The following factors were identified as causal:
- Lack of situational awareness on the part of the crew with regard to the air navigation obstacle.
- Selection of a flight path which was subject to risk given the conditions.
- Lack of Floice collision warning device.
The following factors contributed to the accident:
- Lack of a pre-flight briefing, leading to an incomplete flight preparation.
- Lack of markers of any kind on the cableway.
The following factor was established as neither causal nor directly contributory but was recognised as a factor to risk:
- Chronically high workload of the flying instructor.
