ASW 19 trudelt nach Absacken an der Leeseite in die Felswand

Scex Rouge, Switzerland Alexander Schleicher ASW 19 B

Eine ASW 19 B prallte beim Hangsegeln am Scex Rouge rund 50 m unter der Krete in die Ostwand; der Pilot starb, das Flugzeug wurde zerstört. Bei Westwind von 15-20 kt trug die Luvseite, während die Lee-Ostseite ebenso stark absackte. Zeugen sahen das Flugzeug immer tiefer in die Combe du Dar sinken, wo starker Abwind herrschte und Bahnseile den Hang querten. Vom Abwind erfasst, riss der Pilot die Maschine hart nach links, um den Seilen auszuweichen; sie ging in eine enge Kurve — wahrscheinlicher ins Trudeln — über und schlug nach eineinhalb Umdrehungen in die Wand. Ursache: unzweckmäßige Flugtaktik in einer abwindreichen Schlucht.

  1. Aerotow ridge flight: The pilot aerotowed from Bex around 1448 for a local training flight and later flew ridge-soaring along the Scex Rouge in the Diablerets area.
  2. Leeward downdraft area: The pilot repeatedly flew through the east slope and Dar combe on the leeward side of Scex Rouge, an area known to generate strong downdrafts and turbulence in westerly winds.
  3. Low, deep in combe: At about 1600 the glider was observed flying lower and deeper into the Dar combe on the east side of Scex Rouge, exposing it to strong sink close to terrain and cable car wires.
  4. Abrupt left turn: In attempting to turn left away from the east slope and avoid the cable car cables, the pilot initiated a very tight left turn at low height near the ridge.
  5. Develops steep turn/spin: The glider entered a very steep left bank and likely an incipient or fully developed spin, completing about one and a half turns while descending toward the slope.
  6. Crash - fatal: After roughly one and a half turns the glider struck the east rock face of Scex Rouge about 50 m below the ridge, destroying the aircraft and killing the pilot instantly.
