Narrative:
The accident took place approximately 10 minutes after take-off, at a height of 2800 meters. The aircraft crashed close to the station of a chairlift to the Diavolezza glacier. The pilot, and 2 occupants (both 14) died, the third occupant (17) was severly injured. The flight in a small plane was a first flight made within the framework of a camp for young people organized by Swiss's flying club.

Causes
The accident, in which the aircraft collided with the ground, was caused by inappropriate and risky mountain flying tactics.
The pilot's decision, who had no flight instructor training, to delegate control in a difficult phase to a person who could not fly an aircraft directly contributed to the accident.
A systemic cause of the accident was the lack of safety awareness on the part of the organizers, who allowed pilots who were not qualified as flight instructors to use inexperienced people to fly the aircraft.
