SZD 30 Pirat crash during training flight in Friedersdorf after control issues

On April 24, 2000, a training flight with a SZD 30 Pirat in Friedersdorf ended in a crash following control issues. During the winch launch, the student pilot noticed the ailerons were unresponsive. Despite this, the pilot continued to release at maximum height and attempted to maintain control using rudder inputs. The glider was unable to correct its bank angle, leading to a wing strike during an attempted landing, resulting in the destruction of the aircraft and minor injuries to the pilot. Investigation revealed the aileron control was not connected, which was not detected during pre-flight checks.
