NTSB narrative

According to the flight crew, during the descent for landing, the airplane was approaching about 16,000 ft when air traffic control informed them of reports of moderate-to-severe turbulence. The flight crew immediately attempted several times to contact the flight attendant to inform her to take her seat, but they were unsuccessful. As the airplane descended through about 12,000 ft, it encountered moderate turbulence. After the encounter, the captain asked the first officer to check on the flight attendant and passengers. The first officer subsequently informed the captain that the flight attendant had fallen and was injured and that he assisted her and then secured her into a seat. The airplane was not damaged. The flight attendant sustained a serious injury.

Probable cause

The airplane’s encounter with turbulence during descent, which resulted in a serious injury to a flight attendant.

  • 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: local date, investigation status, damage. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 2020-01-02.
