Read the full NTSB narrative
The pilot was performing aerobatic maneuvers in the glider. He reported that after executing a loop, he entered the glider into a spin. The pilot wrote that during the recovery from the spin the airspeed went above the never exceed velocity for the glider, and the glider developed severe airframe flutter. The pilot exited the glider at approximately 2,070 feet mean sea level, and deployed the parachute which he was wearing. The glider's composite skins on the horizontal stabilizer, elevator, left wing and fuselage sustained skin wrinkling and were delaminated in the accident.
