NTSB narrative
The flight crew was anticipating light turbulence during the descent and notified the cabin and selected the fasten seatbelt sign on prior to descending from 28,000 feet. During the descent, as the flight attendants (FA) were still preparing the cabin for arrival, the turbulence increased to a level the crew categorized as moderate.
During this time, while trying to get to her seat, a FA was thrown against the 3L door and fell to the floor injuring her right ankle. The FA could not complete her duties and was assisted into the last row of seats. Another FA informed the flight crew who arranged for paramedics to meet the airplane.
The FA was transported to the hospital and diagnosed with a broken right tibia in two places.
Probable cause
unexpected encounter with convective turbulence while the flight attendants were preparing for arrival.

- 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.
