K 8 B Kollision mit Zaun bei Außenlandung nahe Enetchirel, Schweiz

Enetchirel, Switzerland Alexander Schleicher K 8 B

Am 14. August 1971 geriet ein Alexander Schleicher K 8 B während eines lokalen Fluges vom Flugplatz Zweisimmen in schwierige Wetterbedingungen. Der Pilot konnte aufgrund starker Winde keine Höhe gewinnen und versuchte eine Außenlandung auf abschüssigem Gelände nahe Enetchirel, Schweiz. Während des Ausrollens berührte der linke Flügel des Segelflugzeugs den Boden, wodurch das Flugzeug nach links abdriftete und mit einem Stacheldrahtzaun kollidierte. Der Pilot blieb unverletzt, aber das Segelflugzeug erlitt erhebliche Schäden. Der offizielle Bericht kam zu dem Schluss, dass die Entscheidung des Piloten, weiter in ungünstige Bedingungen zu fliegen, sowie die Wahl des Landeplatzes zum Vorfall beitrugen.

  1. Aerotow local flight: The pilot took off at 1218 on aerotow from Zweisimmen for a local soaring flight and released at about 1800 m west of the Niderhorn after climbing to roughly 2100 m.
  2. Drift into Diemtigtal: In strong northwesterly winds the pilot allowed the glider to drift over the Niderhorn ridge into the rear Diemtigtal, where it encountered strong sink.
  3. Unfavourable weather: Strong winds, showers or thunderstorms with gusts and turbulence, and rain showers entering the Diemtigtal created difficult soaring and landing conditions.
  4. Continued eastward flight: Hoping to find lift on the opposite side of the valley, the pilot continued flying eastward but was unable to gain altitude.
  5. Decision for outlanding: As rain showers began penetrating the valley, the pilot decided to perform an outlanding on a steep south-facing slope northeast of Enetchirel.
  6. Downslope landing roll: The pilot conducted a landing approach on heading 075° onto terrain sloping about 1:10 downhill, and in strong gusty conditions the glider touched down and rolled approximately 150 m before the left wing contacted the ground, yawing the aircraft left.
  7. Outlanding - damage: Around 1250 the glider, veering left after wing contact, struck a barbed wire fence with its tail, heavily damaging the aircraft while the pilot remained uninjured.
