Probable cause

The pilot's failure to maintain control of the glider, which resulted in the pilot induced oscillations.

Sequence of events

Analysis

Witnesses reported the private glider pilot over controlled the glider at liftoff during an aircraft tow. The glider entered pilot induced oscillations, struck the runway, bounced back into the air with a nose high attitude, and struck the runway twice more, ending in a reported 40 degree nose down impact with the runway. The impact broke the tail boom, separated the rudder, elevators, and crushed the cockpit. The witnesses extracted the pilot and an ambulance took the seriously injured pilot to a local hospital.
