Actual wind conditions and turbulence led to a hard landing
During taxi the right main landing gear ran into a hole leading to a landing gear collapse.
During the final approach in marginal weather conditions, a loss of pilot external visual references led to a go-around. During the go-around, the helicopter briefly hit the ground.
Inadvertently fully extended airbrakes during the entire flight resulted, during an attempt on landing across the runway, in a collision with an obstacle in the safety zone.
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.
