Student Pilot’s Failure To Maintain Airspeed And Altitude Resulting In A Collision With The Ground During The Base To Final Turn Analysis: The solo student pilot reported she was on downwind to land and noted she was a bit lower than usual so she turned base early to compensate. While on the base leg her recollection of events wasn’t clear. She remembered feeling task saturated and that she may not have maintained her altitude and airspeed resulting in the glider impacting the ground during the base to final turn.
