A technical malfunction of the landing wheel retraction and extension system resulted in a wheel-up landing on the asphalt runway.
The touring motor glider bounced during landing, and subsequently made a hard landing in a nose low attitude.
A delayed and/or insufficient flare in combination with a forward airspeed during an autorotation led to an accident.
During a winch launch, the glider bounced and rolled 60° to the left before colliding with the runway.
Full deployment of the airbrakes at low altitude, during a winch start, caused the glider to hit the ground in a steep angle.
A required take-off distance longer that the available take-off distance led to the aircraft collision with nearby trees and the accident.
The local wind conditions most likely affected the handling of the glider during the final approach. As a consequence, the glider crashed at the beginning of the runway.
During landing, the left vingtip of the glider hit a parked aircraft, and the glider crashed.
During climb and upon activation of the heating system, the pilots experienced white smoke in the cabin.
During a winch launch, the left wing touched the runway and the glider crashed.
