NTSB narrative
During the landing sequence, the student pilot pushed the control stick of the glider forward just before touchdown. This action resulted in the glider landing hard and bouncing about one foot back into the air. The student pilot then forced the glider onto the runway a second time, after which it bounced about five feet back into the air. In trying to recover from the second bounce, the student pilot forced the glider onto the runway a third time. When the glider again bounced back into the air, it pitched up to a degree such that the aft end of the fuselage contacted the asphalt runway. The student pilot then leveled the glider and allowed it to descend to the runway surface in a near level attitude. Both the composite tail boom and the composite vertical fin were cracked.
Probable cause
The student pilot’s inadequate recovery from a bounced landing.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
