Probable cause

The pilot's improper descent rate that led to a hard landing and porpoise, and his improper recovery from the ensuing bounced landing, resulting in the eventual separation of the empennage. A factor was the updraft.

Analysis

According to the pilot, he was flaring above the runway when the glider experienced an updraft and began a slight climb. In order to counteract the slight climb, the pilot added additional spoiler. The glider then came down hard on the runway and bounced back into the air. The glider continued to oscillate in this manner for three oscillations until the empennage separated from the fuselage. The glider then rolled off the runway and came to a stop.
