Colisión de un DG 300 Elan durante un aterrizaje en campo cerca de Andermatt, Suiza
El 23 de julio de 1990, un DG Flugzeugbau DG 300 Elan se vio obligado a realizar un aterrizaje en campo cerca de Andermatt, Suiza, debido a condiciones térmicas desafiantes. El piloto intentó aterrizar en un campo designado a lo largo de la carretera del Gotardo, pero no pudo perder suficiente altitud debido a un viento de cola. Durante el aterrizaje, el ala derecha golpeó un obstáculo, haciendo que el planeador girara 90 grados y se detuviera en un prado cercano. El piloto sufrió heridas leves y la aeronave resultó significativamente dañada. El incidente se atribuyó a un enfoque de aterrizaje mal calculado y a una consideración insuficiente de las condiciones del viento.
- Cross-country cruise: The pilot departed Zweisimmen by aerotow for a 500 km cross-country flight and was returning after abandoning the task due to poor thermals.
- Forced outlanding need: Near Andermatt, deteriorated thermal conditions forced the pilot to plan an outlanding instead of continuing the flight.
- Tailwind landing field: The pilot selected a designated outlanding field along the Gotthard road that, under the prevailing NE wind, could only be approached with a tailwind and without fully considering the wind conditions.
- High tailwind approach: After flying a circuit, the pilot conducted the final approach to the SW with a tailwind, using full airbrakes and a sideslip in an attempt to lose height.
- Aborted glide over obstacles: Unable to reduce altitude sufficiently and to avoid obstacles at the end of the field, the pilot ended the sideslip, retracted the airbrakes, and pulled up to try to land in a meadow beyond the obstacles.
- Wing strikes obstacles: During this maneuver the right wing struck a stack of reinforcing mesh and an excavator, causing the glider to yaw about 90 degrees and come to rest in the adjacent meadow.
- Crash - minor injury: The glider stopped in the meadow with substantial damage, and the pilot sustained minor injuries.
