NTSB narrative
According to the pilot, during the landing approach, she noted that the wind had changed direction and increased to about 5 knots. The pilot identified a suitable place to land, and, after clearing power lines, she made a steep approach. The balloon touched down on uneven ground and the basket tipped. The pilot was venting the balloon at the time and when the basket touched down, the vent line pulled her partially out of the basket. The basket dragged across the ground a few feet before becoming airborne again, and the pilot continued to hang onto the vent line. The two passengers then jumped out of the basket and the vent line was ripped out of the pilot’s hands. The balloon continued flight, unoccupied, and landed approximately 1/2 mile from the intended landing location. During the accident sequence, the balloon was torn and the skirt was burnt.
Probable cause
The pilot’s failure to maintain control of the balloon during the landing on uneven ground.

- 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.
