Aterrizaje en campo y pérdida de sustentación de un Ka 8 cerca del aeródromo de Birrfeld con vientos fuertes
El 17 de abril de 1966, un Alexander Schleicher Ka 8 experimentó un aterrizaje brusco a 500 metros al sur del aeródromo de Birrfeld en Suiza. El piloto regresaba de un vuelo térmico cuando fuertes vientos del norte obligaron a un aterrizaje en campo. Al intentar aterrizar, el planeador entró en pérdida desde aproximadamente 4 metros sobre el suelo, resultando en daños significativos en la unión del ala al fuselaje. No se reportaron heridos.
- 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.
