Crash d'un Ka 6 lors d'une tentative d'atterrissage près de Stettfurt, Suisse
Le 23 avril 1988, un Alexander Schleicher Ka 6 BR s'est écrasé à environ 1 km au sud-est de Stettfurt, Suisse. Le planeur a été observé effectuant un virage à gauche pour un atterrissage en campagne dans un champ, mais a dépassé sa vitesse minimale et a décroché. Le pilote, qui ne pouvait pas se souvenir du vol, a subi de graves blessures et l'appareil a été détruit. L'accident a été attribué à une formation de vol insuffisante du pilote et à une stratégie d'atterrissage inappropriée impliquant une approche par vent arrière.
- Winch launch local flight: The pilot took off at about 1300 local in the Ka-6 CR HB-618 from Amlikon by winch launch for a local soaring flight.
- Low recent experience: The pilot had generally low and not current flight training, with more than eight months since his last flight on the accident type.
- Late outlanding decision: After losing height while flying along the south side of the Sonnenberg and no longer finding lift, the pilot decided at about 200 m above the valley floor to perform an off-field landing.
- Tailwind landing attempt: Over a large, obstacle-free field south of the Lauche stream, the pilot overflew the landing area and set up for a tailwind landing with an estimated 10 kt tailwind.
- Stall in landing turn: During the final left turn for the tailwind landing, the glider’s airspeed dropped below minimum flying speed, leading to a stall and loss of control.
- Crash - serious injury: The glider impacted the ground in a left bank of about 60 degrees approximately 1 km southeast of Stettfurt, seriously injuring the pilot, destroying the aircraft, and causing minor ground damage.
