Kollision des Mucha Standard mit Hindernis während der Landung auf dem Flugplatz Amlikon

Am 26. August 1972 war ein Mucha Standard Segelflugzeug in einen Zwischenfall auf dem Flugplatz Amlikon in der Schweiz verwickelt. Während des Landeanflugs stellte der Pilot fest, dass das Segelflugzeug zu niedrig war, um die geplante lange Landung durchzuführen. Beim Versuch, den Anflug anzupassen, kollidierte das Segelflugzeug mit Weidenbüschen in der Nähe des Flusses Thur und stürzte in das Flussbett. Der Pilot blieb unverletzt, aber das Segelflugzeug erlitt erhebliche Schäden. Die Untersuchung ergab, dass die Kollision auf die Unaufmerksamkeit des Piloten gegenüber Hindernissen während des Landeanflugs zurückzuführen war.

1. Circuit and approach: After a winch launch and cable release at about 400 m AGL, the pilot flew the landing circuit and turned onto final for runway 07 at Amlikon.
2. Too-low final approach: On final approach the pilot realized he was too low to execute the previously agreed long landing needed to leave space for the following Ka-6.
3. Traffic and obstacle constraints: The right half of the runway threshold area was partially occupied by two gliders and a winch cable retrieval vehicle, and the pilot was also trying to keep the left half free for the Ka-6.
4. Offset landing attempt: To keep the left side free and avoid the parked aircraft and vehicle, the pilot decided to land diagonally into the right half of the runway behind the retrieval vehicle.
5. Left deviation for alignment: To achieve the desired diagonal landing direction, the pilot maneuvered left of the approach path while concentrating on the aircraft and vehicle on the field and did not adequately monitor obstacles beside the approach.
6. Wing strikes bushes: About 65 m before the runway markings and roughly 50 m left of the approach axis, the left wingtip struck approximately 4 m high willow bushes on the bank of the Thur river.
7. Crash - no injury: The glider was violently yawed left and crashed into the riverbed, heavily damaging the aircraft but leaving the pilot uninjured.
