Mucha Standard Strömungsabriss während des Anflugs auf den Flugplatz Hausen am Albis

Hausen am Albis Flugplatz (LSZN), Switzerland SZD SZD-22B

Am 28. April 1968 erlebte ein Mucha Standard Segelflugzeug einen Strömungsabriss während der Anflugphase auf den Flugplatz Hausen am Albis in der Schweiz. Der Pilot, der unverletzt blieb, traf unerwartet auf ein weiteres Segelflugzeug während des Anflugs, was dazu führte, dass er die Luftbremsen ausfuhr. Diese Handlung führte dazu, dass das Flugzeug überzog und auf den Boden aufschlug. Der Mucha Standard erlitt erhebliche Schäden, aber es wurden keine Verletzungen gemeldet. Der Vorfall wurde auf das Versäumnis des Piloten zurückgeführt, die Mindestgeschwindigkeit während der letzten Kurve beizubehalten.

  1. Aerotow — landing: After an aerotow launch and local soaring, the pilot returned to Hausen am Albis and flew the standard landing circuit to runway 27.
  2. Other glider ahead: While in the crosswind/base leg, the pilot suddenly saw another glider about 80 m directly ahead already established on final approach, which he had not previously noticed.
  3. Low speed in circuit: Eyewitnesses reported the Mucha was already flying at minimal airspeed in the base leg, leaving little margin above stall, especially in turns.
  4. Airbrakes and tailwind: As he turned right into final to increase spacing from the other glider, the pilot extended the airbrakes and was flying with a slight tailwind component, further increasing stall risk.
  5. Stall and recovery attempt: The glider abruptly rolled off over the right wing; the pilot pushed to regain speed and then pulled due to ground proximity, partially recovering bank but not fully arresting the sink.
  6. Ground and fence contact: The glider struck a ground undulation with the fuselage and then the left wing contacted an electric livestock fence, yawing the aircraft to the left.
  7. Hard landing - damage: The glider came to rest roughly 90 degrees to the approach path on the airfield with the fuselage broken and wing fabric torn, while the pilot was uninjured.
