Colisión del Mucha Standard con obstáculo durante el aterrizaje en el aeródromo de Amlikon

El 26 de agosto de 1972, un planeador Mucha Standard estuvo involucrado en un incidente en el aeródromo de Amlikon en Suiza. Durante la aproximación de aterrizaje, el piloto encontró que el planeador estaba demasiado bajo para ejecutar un aterrizaje largo planeado. Al intentar ajustar la aproximación, el planeador colisionó con arbustos de sauce cerca del río Thur, provocando su caída en el lecho del río. El piloto resultó ileso, pero el planeador sufrió daños significativos. La investigación concluyó que la colisión fue resultado de la falta de atención del piloto a los obstáculos durante la aproximación de aterrizaje.

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.
