Accidente de Ka 6 durante intento de aterrizaje cerca de Stettfurt, Suiza
El 23 de abril de 1988, un Alexander Schleicher Ka 6 BR se estrelló aproximadamente a 1 km al sureste de Stettfurt, Suiza. Se observó que el planeador realizaba un giro a la izquierda para un aterrizaje de emergencia en un campo, pero excedió su velocidad mínima y entró en pérdida. El piloto, que no pudo recordar el vuelo, sufrió heridas graves y la aeronave fue destruida. El accidente se atribuyó a la formación de vuelo insuficiente del piloto y a una estrategia de aterrizaje inapropiada que involucraba un enfoque con viento de cola.
- 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.
