NTSB narrative
The flight was descending from 14,000 feet to 13,000 feet when it encountered severe turbulence. The FASTEN SEATBELTS sign was reportedly illuminated. The captain called the flight attendant on the intercom, but she did not answer. An emergency medical technician (EMT), who was a passenger on the flight, answered and reported the flight attendant was lying on the floor unconscious. The EMT and an off-duty United flight attendant tended to the injured flight attendant. The captain declared an emergency and the airplane landed at its destination. The flight attendant was transported to a hospital with serious injuries.
Probable cause
The encounter with severe turbulence causing serious injury to the flight attendant.

- 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, damage. 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.
