Ka 2B Kollision mit Gelände nahe Ennenda während Hangflug

Am 31. Mai 1982 kollidierte ein Alexander Schleicher Ka 2B Segelflugzeug während eines Hangfluges nahe Ennenda, Schweiz, mit dem Gelände. Der Pilot und ein Passagier waren zuvor vom Flugplatz Mollis gestartet. Beim Versuch, entlang des Chrisegg-Hangs an Höhe zu gewinnen, verlor das Segelflugzeug an Geschwindigkeit und Höhe, was zu einer Kollision mit dem Hang führte. Der Pilot erlitt leichte Verletzungen, während der Passagier schwer verletzt wurde. Das Segelflugzeug wurde beim Aufprall zerstört.

1. Ridge soaring flight: After an aerotow departure from Mollis, the pilot conducted a several-hour soaring flight and was ridge soaring along the west slope of Chrisegg to gain height.
2. Low experience, fatigue: The pilot had relatively low total gliding experience and reported feeling somewhat tired after the long flight, which likely degraded his judgment of terrain clearance.
3. Tight turn near slope: While flying close to the steep mountainside and finding lift, the pilot initiated a right-hand circling turn with insufficient distance from the slope.
4. Sink and speed loss: On the valley side of the turn the glider encountered sink and a reduction in airspeed, eroding its energy margin near the terrain.
5. Pushed toward slope: To regain airspeed, the pilot pushed the nose down toward the mountainside while still in close proximity to the steep slope.
6. Collision with slope: With insufficient height and distance to recover, the glider struck the steep slope in an angled attitude near the upper edge of a small snow cone.
7. Crash - serious injury: The glider was destroyed on impact, the pilot was slightly injured, and the passenger sustained serious injuries.
