Analysis

During an instructional flight in a glider, the student was high on the final approach, deployed the spoilers and entered a forward slip. The flight instructor stated that shortly after, the student “suddenly and unexpectedly” pulled back on the control stick while the rudder and ailerons were cross controlled. The flight instructor immediately took control, pushed the control stick forward and closed the spoilers; however, insufficient altitude remained for a full recovery, which resulted in a hard landing and serious injuries to the instructor. The flight instructor reported that there were no preimpact malfunctions or anomalies that would have precluded normal operation.
