Atterrissage en campagne et décrochage d'un Ka 8 près de l'aérodrome de Birrfeld par vent fort
Le 17 avril 1966, un Alexander Schleicher Ka 8 a effectué un atterrissage difficile à 500 mètres au sud de l'aérodrome de Birrfeld en Suisse. Le pilote revenait d'un vol thermique lorsque de forts vents du nord ont forcé un atterrissage en campagne. En tentant de se poser, le planeur a décroché à environ 4 mètres du sol, entraînant des dommages importants à la fixation de l'aile au fuselage. Aucun blessé n'a été signalé.
- Local thermic flight: The pilot launched from Birrfeld for a local thermic soaring flight in the vicinity of the airfield.
- Front brings strong wind: After about 1.5 hours a front approached, bringing strong local northerly wind that prevented the pilot from reaching Birrfeld for landing.
- Forced outlanding: Unable to reach the airfield, the pilot committed to an outlanding in a field about 500 meters south of Birrfeld.
- Low turn before wires: In low height over the ground, the pilot attempted to turn in for landing in front of an electrical power line.
- Speed allowed to decay: During this low-altitude turn the pilot allowed the airspeed to decrease excessively, causing the glider to lose speed and sink from about 4 meters height.
- Outlanding - damage: The glider dropped hard onto the ground during the outlanding, significantly damaging the wing-to-fuselage attachment but causing no injuries.
