Standard Cirrus kippt in tiefer Umkehrkurve vor dem Flugplatz ab

Hildisrieden, Switzerland Schempp-Hirth Standard Cirrus

Der Pilot eines Standard Cirrus wurde schwer verletzt, als das Segelflugzeug in tiefer Umkehrkurve bei Hildisrieden abkippte und zerstört wurde. Auf seinem ersten Flug seit fast einem Jahr zeigte der zu hoch gestellte Höhenmesser rund 150 m zu viel; der Pilot wähnte sich nahe 1300 m, war aber auf 1050 m. Bei schwacher Thermik, 4 km Sicht und NO-Böen verlor er Höhe und flog zurück. In etwa 100 m leitete er die Kehre in den Rückenwind ein; dabei unterschritt der Cirrus die Mindestfahrt und schlug auf. Ursache war das Unterschreiten der Mindestgeschwindigkeit in geringer Höhe; geringe Übung, schlechte Sicht und Böen erschwerten die Steuerung.

  1. Aerotow training flight: The pilot, with very little recent flight training, departed Luzern-Beromünster on an aerotow training flight after an interruption of almost one year.
  2. Altimeter mis-set: The altimeter was incorrectly set to 1040 hPa instead of the actual 1024 hPa QNH, causing it to overread by about 150 m and giving the pilot an overly optimistic impression of his height.
  3. Low altitude near field: After releasing at about 1050 m and losing height in weak thermals with poor visibility and gusty wind, the pilot reached the field at only about 100 m, unable to reach the runway.
  4. Turn downwind at low height: Over a small wood near Schopfen, at about 100 m above ground, the pilot initiated a 180° reversal turn into downwind to reposition despite the low height and gusty conditions.
  5. Stall in reversal turn: During this low-altitude reversal turn the glider’s airspeed dropped below minimum flying speed, leading to a stall and loss of control.
  6. Crash - serious injury: The glider impacted nose-first at the edge of a field, bounced and rotated 180° before striking tail-first in a meadow, destroying the aircraft and seriously injuring the pilot.
