NTSB narrative
The airplane was approaching its destination, at 10,000 feet, and the seat belt sign had been illuminated for 10-15 minutes, when the crew noticed that clouds ahead "appeared bumpy." The flight attendant was notified, and she advised the passengers of possible turbulence via the public address system. A passenger subsequently got out of her seat to use the lavatory, and upon leaving the lavatory, while the airplane was in a cloud and experiencing turbulence, she fell and broke her ankle.
Probable cause
The passenger's failure to heed the flight attendant warning and the seat belt sign. A factor was the turbulence.

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, 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.
