Absturz eines Standard Cirrus bei der Rückkehr zum Flugplatz nahe Hildisrieden, Schweiz

Hildisrieden, Switzerland Schempp-Hirth Standard Cirrus

Am 17. Mai 1992 war ein Schempp-Hirth Standard Cirrus in einen Unfall nahe Hildisrieden, Schweiz verwickelt. Der Pilot, der nach einer langen Pause einen Trainingsflug absolvierte, wurde auf eine Höhe von 1050 Metern geschleppt, glaubte jedoch fälschlicherweise, er sei auf 1300 Metern aufgrund einer falschen Höhenmessereinstellung. Bei schwachen Thermiken und schlechter Sicht versuchte der Pilot, zum Flugplatz zurückzukehren. Während einer Kurve in geringer Höhe kam es zu einem Strömungsabriss, und das Segelflugzeug stürzte ab, was zu erheblichen Schäden am Flugzeug und schweren Verletzungen des Piloten führte.

  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 an actual height of about 1050 m and losing height in weak thermals and poor 4 km visibility with a gusty NE wind, the pilot approached the airfield area and found himself at only about 100 m above ground unable to reach the runway directly.
  4. Turn downwind at low height: Over a small wood near the hamlet of Schopfen, at about 100 m above ground, the pilot initiated a 180° reversal turn into downwind in an attempt 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.
