Cat. 2 investigation report: simplified-format report, adapted to the circumstances of the occurrence and the investigation stakes.
While flying along the rock face of Parmelan mountain, the pilot passed close to the Parmelan refuge lift cable a first time without seeing it. On the return leg, the glider was lower, below the ridge line and closer to the rock wall. It is likely that the pilot could not see either the refuge or the pylon and was therefore not alerted to the presence of the cable.
The collision of the left wing with the cable destabilised the glider and led to the in-flight loss of control.
