What happened
During the landing sequence, the pilot reported encountering blustery winds ranging from 15 to 20 knots. The approach began with the pilot turning to final at 350 feet using full spoilers. As the altitude decreased to 200 feet, the spoiler deployment was reduced to 25 percent while maintaining a speed of 75 to 80 miles per hour (mph). At 100 feet, the pilot increased the spoilers to 50 percent.
At an altitude of 25 feet, the pilot experienced a sudden loss of velocity, which was immediately followed by a nose-down attitude. Upon initial contact with the runway, the glider's nose lifted, causing the aircraft to become airborne again. In an attempt to flare, the pilot applied full spoilers and performed a forward slide. This resulted in the nose touching down, followed quickly by the tail contacting the ground. The glider subsequently became airborne one final time before touching down and coming to a stop within 15 to 20 feet of the initial contact.
