NTSB narrative
During the approach to landing, the balloon's descent rate was about 300 feet per minute. About 200 feet above the ground the balloon encountered a strong windshear, increasing its horizontal speed over the ground to about 30 knots. The balloon continued descending at about 300 feet per minute until touching down, at which time its basket tilted over and began to drag for about 200 yards, with the last 125 yards over rocky ground. One of the passengers sustained a serious injury due to his arm being stuck between the basket and the ground. The chase crew arrived at the scene about 40 seconds later. No anomalies were reported with the balloon prior to the flight.
Probable cause
The pilot's inadequate weather evaluation during the landing approach. Contributing to the accident were windshear and rocky terrain.

Source notes (4)
- 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, coordinates. 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.
