NTSB narrative
While in descent, about flight level 270, the airliner encountered severe turbulence which resulted in the serious injury of two passengers. According to the captain, the seat belt sign was illuminated, and the cabin crew made at least two advisory announcements. Two passengers confirmed that the seat belt sign had been illuminated for most of the flight, but they and several other witnesses noted that passengers were up and moving about when the event occurred, as were the flight attendants. Six passengers provided statements that they heard no announcements or warnings to remain seated. The onset of the turbulence event was described as sudden, abrupt, and without warning.
Probable cause
The airplane's inadvertent encounter with severe turbulence.

- 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.
