NTSB narrative
During an en route descent, the flight crew noted adverse weather ahead and illuminated the fasten seatbelt sign. Immediately afterward, a flight attendant made a passenger announcement advising that the seatbelt sign was illuminated. Although the seatbelt sign was illuminated, an elderly passenger, who was unable to use the restroom before boarding the accident flight, left her seat for the lavatory. While the passenger was out of her seat, the flight encountered what the captain later reported to be about 2 to 3 seconds of light to moderate turbulence. The standing passenger fell to the floor and was injured. The flight crew arranged for medical personnel and equipment to meet the airplane at its destination airport. The flight continued and landed uneventfully, and the injured passenger was taken to a hospital for treatment of her injuries.
Probable cause
The passenger’s failure to adhere to flight and cabin crewmembers’ instructions to remain seated in anticipation of adverse weather and turbulence along the airplane’s flight path.

- 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, 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.
