Colisión de un DG-100 con líneas eléctricas durante un intento de aterrizaje en campo cerca de Landeyeux, Suiza

El 16 de junio de 1984, un incidente ocurrió con un DG Flugzeugbau DG-100 cerca de Landeyeux, Suiza. El piloto, en un vuelo de entrenamiento, decidió realizar un aterrizaje en campo tras perder altitud. Al intentar aterrizar en un campo, el piloto calculó mal la altura del planeador e inició un giro, lo que llevó a una pérdida de sustentación. El planeador colisionó con líneas eléctricas antes de estrellarse, pero no se reportaron heridos. La aeronave fue destruida en el incidente.

1. Local training flight: The pilot departed Neuchâtel by aerotow for a local training flight and released at about 1600 m near Mont Racine before proceeding along the ridge toward Chasseral.
2. Unable maintain height: After encountering sink and downdrafts leaving the Val-de-Ruz and failing to find expected lift on the Chaumont ridge, the pilot realized he could no longer maintain sufficient height and needed to plan an outlanding.
3. Continued toward ridge: Despite having already selected a suitable field near Engollon and still having 300–380 m in reserve, the pilot continued toward the north slope of Chaumont instead of committing to a direct outlanding.
4. Height misjudged: When turning back from the Chaumont slope toward the chosen field, the pilot misjudged his remaining height and believed it sufficient to fly a standard circuit rather than a direct approach.
5. Abandoned direct landing: Approaching overhead the intended field, the pilot first prepared for a straight-in landing into an adjacent field and briefly deployed airbrakes, then changed his mind again and initiated a left turn to fly a conventional pattern.
6. Low-speed turning stall: During the left turn toward the planned circuit path, at low height and with insufficient speed, the glider stalled and descended into the path of an electrical line.
7. Crash - no injury: The glider struck the power line, causing a short circuit, and then crashed to the ground destroying the aircraft but leaving the pilot uninjured.
