NTSB narrative
About five to 10 minutes after the flight attendants began cabin service, the aircraft entered an area of light to moderate turbulence. The flight crew directed the flight attendants to discontinue cabin service and take their seats, and initiated a descent to an altitude where the air was reported smooth. The flight attendants were in the process of attempting to stow a beverage cart in the aft galley when the aircraft encountered turbulence that momentarily subjected the aircraft to negative G forces. The unseated flight attendants were thrown up off the floor in this encounter, with at least one flight attendant striking her head on the ceiling. The unsecured beverage cart landed on top of this flight attendant's foot, fracturing bones in her foot. Three other flight attendants received minor injuries. The flight crew reported that this encounter occurred in the descent just above flight level (FL) 330, about 90 miles east of the Kimberly, Oregon (IMB) VORTAC. Upon being notified of this situation, the flight crew initiated actions to deal with the situation, and continued on to the flight's destination with the remainder of the flight proceeding uneventfully.
Probable cause
An inflight encounter with turbulence that occurred before flight attendants could finish stowing a beverage cart and return to their seats.

- 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.
