The DR.400/180 aircraft took off from runway 25 at Sion airfield with the pilot and three passengers on board. After take-off, the aircraft made a left turn and flew along the south side of the Rhone valley towards Sierre to gain altitude. At 15:45, the pilot turned right and decided to follow the Val d'Anniviers. He made two wide orbits over Chandolin and then continued his climbing flight towards Grimentz where he again started a wide orbit. It then left the Val d'Anniviers and headed towards the Lake of Moiry which it flew over at 16:05, at an altitude of 3050 m.
From there, the pilot took a southern heading and flew over the glacier of Moiry where he started a series of three circles, in climbing flight, to reach the altitude of 3300 m. Flying then with an east heading, he passed to the north of the Pigne de la Le and reached the Val d'Anniviers, which it followed in a southerly direction, as on the previous flight.
The aircraft climbed slightly and approached the Grand Cornier glacier which it flew over at 16:14 min at an altitude of 3450 m. The pilot then started two wide orbits to the left over the Roc Noir. At 16:21 min, at the end of the second orbit over the Durand glacier, the pilot took a south-east heading and maintained an altitude of 3480 m. Its height over the glacier was then approximately 250 m and its ground speed approached 80 kt. The pilot maintained this flight direction and altitude for approximately 20 seconds, heading towards the east ridge of Col Durand located at 3436 m. Then, the pilot started a right turn towards the Col Durand and the aircraft collided at 16:22 with the scree on the north side of the east ridge. The plane was destroyed and the four occupants were fatally injured. The distress beacon was activated. No fire broke out.
Causes
The accident was caused by a high-risk mountain flying tactic which resulted in a collision with the terrain.
The pilot's poor flight training contributed to the accident.
