Incidente de DG-200 durante lanzamiento con torno en el aeródromo de Fricktal Schupfart
El 22 de agosto de 1982, un DG Flugzeugbau DG-200/17 experimentó un incidente durante un lanzamiento con torno en el aeródromo de Fricktal Schupfart en Suiza. Durante el lanzamiento, el planeador entró en pérdida y se estrelló desde una altura de aproximadamente 20-30 metros, resultando en la destrucción de la aeronave. El piloto sufrió heridas graves. La investigación determinó que el piloto pasó al ascenso sin una reserva de velocidad suficiente, y una posible falta de aceleración óptima del torno pudo haber contribuido al accidente.
- Winch launch takeoff: During a winch launch from runway 08, the glider began its ground roll and initial liftoff with the pilot immediately sensing that acceleration was unusually slow.
- Suboptimal configuration: For the winch launch the glider was not in the recommended configuration, with flaps at 0° instead of +4° and only slightly nose-heavy trim, reducing longitudinal stability and climb margin.
- Possible weak acceleration: The winch, operated by a relatively inexperienced winch driver, may not have provided optimal acceleration, leading to a prolonged low-height, low-speed segment after liftoff.
- Climb initiated low speed: After a long, shallow flight just above the ground and only a slight increase in speed, the pilot began to raise the nose into climb without an adequate speed reserve.
- Pitch and roll corrections: At about 2–3 m AGL the pilot briefly pushed to gain speed, then slowly pulled back to climb and applied right aileron when the glider started to roll left.
- Stall and wing drop: Approximately 20–30 m above ground, the glider stalled and departed controlled flight, dropping almost vertically over the right wing despite the pilot’s correction.
- Crash - serious injury: The right wing struck the ground first, followed by the nose impact, destroying the glider and seriously injuring the pilot, with the wreckage coming to rest about 190 m from the start point.
