ASW 19B aterrizaje duro tras enredo de cable en Samedan
El 21 de mayo de 1988, un Alexander Schleicher ASW 19B experimentó un aterrizaje duro en el aeropuerto de Samedan durante un lanzamiento por torno. Un segundo cable de torno se enredó con la rueda de cola del planeador, afectando su rendimiento de ascenso. El piloto soltó el cable de lanzamiento a aproximadamente 140 metros de altitud, pero el planeador era difícil de controlar debido al paracaídas abierto del segundo cable. La aeronave aterrizó duramente al lado de la pista, resultando en daños significativos, pero el piloto resultó ileso. La investigación destacó un espaciado insuficiente entre los cables de torno y una mala organización en tierra como factores contribuyentes.
- Winch launch takeoff: The pilot began a winch launch in ASW 19B HB-1856 from runway 03 at Samedan for a local soaring flight.
- Second cable snags tail: During the initial climb, the parallel second winch cable, with its parachute still attached, became caught on the glider’s tail skid.
- Insufficient cable spacing: The second winch cable had been laid out only about 2.5 m from the launch cable and not moved farther away when the first cable was attached to the glider.
- Poor ground organization: Ground personnel left the second cable’s parachute attached and allowed people to remain near the second cable, indicating inadequate awareness and organization of winch launch hazards.
- Pilot releases launch cable: Noticing poor climb performance, the pilot released the primary launch cable at about 140 m above ground.
- Control severely limited: With the second cable’s open parachute trailing, the glider’s controllability was greatly reduced due to the stabilizing and drag effects.
- Hard landing - damage: The glider impacted the ground hard to the right of runway 03, sustaining severe damage while the pilot remained uninjured.
