Aircraft involved

Probable cause & findings

The student pilot’s improper landing flare in gusting crosswind conditions, which resulted in a hard landing.

Factual narrative

The solo student pilot reported that, during landing, about 10 ft above ground, the airplane was "hit by a tail gust/downdraft" and the glider landed hard. The glider sustained substantial damage to the fuselage. The automated weather observation station located on the airport reported that, about 8 minutes before the accident, the wind was from 170° at 10 knots, gusting 14 knots. The glider landed on runway 8G. The solo student pilot reported that, during landing, about 10 ft above ground, the glider was "hit by a tail gust/downdraft," then it landed hard.
