Collision du Mucha Standard avec un obstacle lors de l'atterrissage à l'aérodrome d'Amlikon
Le 26 août 1972, un planeur Mucha Standard a été impliqué dans un incident à l'aérodrome d'Amlikon en Suisse. Lors de l'approche d'atterrissage, le pilote a constaté que le planeur était trop bas pour effectuer un atterrissage long prévu. En tentant d'ajuster l'approche, le planeur a heurté des buissons de saules près de la rivière Thur, provoquant son crash dans le lit de la rivière. Le pilote est resté indemne, mais le planeur a subi des dommages importants. L'enquête a conclu que la collision résultait de l'inattention du pilote aux obstacles pendant l'approche d'atterrissage.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Crash - no injury: The glider was violently yawed left and crashed into the riverbed, heavily damaging the aircraft but leaving the pilot uninjured.
