Un LS 3 percute un flanc de montagne après une perte de contrôle en haute montagne

Wildstrubel, Switzerland Rolladen-Schneider LS3-17

Le pilote d'un LS 3 a été tué lorsque le planeur a percuté un flanc de montagne après une perte de contrôle près du Wildstrubel ; planeur détruit. Le pilote a signalé en dernier ~3200 m MSL ; l'épave a été retrouvée sur le flanc nord-ouest à ~3000 m. Volant vers l'est près du plafond, le planeur a heurté le rocher de l'extrémité de l'aile droite. Le pilote emportait une caméra vidéo et son harnais était débouclé, la verrière restant fermée ; une blessure à l'œil correspondait au viseur. Sans cause technique ni médicale, la cause probable était une perte de contrôle inexpliquée, le filmage et le vol près du plafond étant relevés.

  1. Aerotow mountain soaring: The pilot aerotowed from Zweisimmen at 14:47 and proceeded to soar in the Lenk–Wildstrubel mountain area, later reporting position at 3200 m near Wildstrubel around 17:00.
  2. Flight near cloudbase: The glider was operating close to the local cloudbase around 3200–3300 m, reducing vertical clearance from terrain near the Wildstrubel ridge.
  3. Unfastened harness: The pilot’s seat harness was not latched in the central buckle at the time of the accident, indicating he was not properly strapped in.
  4. Use of video camera: The pilot carried a video camera and injuries were compatible with contact with the viewfinder, suggesting he may have been filming and visually distracted from aircraft control and terrain clearance.
  5. Loss of control in flight: For undetermined reasons, the pilot lost effective control of the glider while flying near the Wildstrubel at high altitude close to terrain.
  6. Wingtip strikes terrain: While flying on an easterly track, the right wingtip impacted a rock face on the northwest flank of the Wildstrubel, indicating insufficient terrain clearance.
  7. Crash - fatal: Following the wingtip impact, the glider broke up and the wreckage fell about 300 m down the northwest flank of the Wildstrubel, destroying the aircraft and fatally injuring the pilot.
