NTSB narrative
The glider pilot reported that, during an aerotow takeoff, the glider weather vaned off the paved surface of the runway about 200 ft into the takeoff roll. The pilot stated that the glider's tailwheel was too small to roll on the unpaved surface and that the glider's acceleration in the dirt "was not as fast as it needed to be." The tow plane became airborne before the glider, and shortly after the glider became airborne at low airspeed, about 10 to 15 ft above ground level, the glider settled into sage brush and contacted the ground, resulting in substantial damage to the fuselage and right wing. The glider pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation, and that the accident could have been prevented by releasing from the tow plane "before leaving the ground."
Probable cause
The pilot’s failure to abort the takeoff in a timely manner, which resulted in glider settling into sage brush.

- 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.
