NTSB narrative
The flight encountered severe turbulence and two lightning strikes while the flight was level at 13,000 feet in instrument meteorological conditions. The seatbelt sign had been illuminated since the passing through 18,000 feet during the descent and was on at the time of the encounter. Prior to the turbulence, a passenger had ignored the seatbelt sign and entered the lavatory, unbeknownst to the flight attendants, who were preparing the cabin for landing. At the time of the turbulence encounter, the passenger was exiting the lavatory and was severely injured. Inflight turbulence and convection advisories had been forecasted for the area where the flight encountered the turbulence. There was a convective SIGMET for severe thunderstorms and for occasional turbulence between 16,000 feet and FL 280. In addition, there were several pilot reports of turbulence in the area.
Probable cause
an encounter with convective turbulence that resulted in injury to a passenger who was not seated when the seatbelt sign was illuminated.

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, 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.
