NTSB Narrative Summary Released at Completion of Accident

Light turbulence prevailed during the climb after takeoff, and the seatbelt sign remained illuminated. About 230 miles northwest of the departure airport, at 34,000 feet, the turbulence subsided; however, more turbulence was forecasted for about 150 miles ahead of the airplane. The captain announced to the passengers that the seatbelt sign would be turned off for 10 minutes to allow them an opportunity to move about the cabin, but would be turned on again due to the upcoming turbulence. About 3 minutes after turning the seatbelt sign back on, the airplane encountered moderate turbulence. During that time, two passengers fell as they were attempting to sit down. In addition, a flight attendant fell to the floor as she was attempting to sit, and fractured her pelvis.

NTSB Probable Cause Narrative

An encounter with turbulence during cruise flight.
