Narrative:
The pilot, accompanied by one passenger, took off on a winch launch from Chambéry Challes-les-Eaux Airfield for a local flight.
He used the uplifts over the mountains in the vicinity of the aerodrome to reach an altitude of approximately 1,400 m. He then headed northwards up to Bange mountain where he made a U-turn and headed in the direction of the Cirques de Montagnole, located south of the departure aerodrome, which he reached at an altitude of approximately 1,000 m. After
gaining altitude in the first cirque, he joined the second cirque. With the glider losing altitude, the pilot decided to make a U-turn and moved away from the slope. The glider then suddenly lost altitude.
Knowing that he would not be able to avoid collision with the vegetation, the pilot issued a distress call over the air/air frequency used by the Challes-les-Eaux glider pilots. Seeing the top of the trees approaching, he fully pitched the glider nose up and landed on the treetops. The glider fell flat into the trees.

Contributing factors
The following factors may have contributed to the collision with the vegetation:
- The pilot’s decision to continue the flight in the cirques despite not being able to easily find the uplifts.
- The pilot’s possible misperception of the wind.
