NTSB Narrative Summary Released at Completion of Accident

The flight was descending out of FL290, when it encountered severe turbulence. The first officer was the pilot flying at the time, the speed brakes were extended, the airspeed was 290 knots, and weather radar was in use, with no indications of conditions associated with turbulence. There were no reports of turbulence from either air traffic control (ATC), or other aircraft. The seat belt sign was "ON" for 10 minutes prior to the accident. At the time of the accident the flight attendants were in the galleys and aisles performing cabin duties associated with the beginning of descent. When the turbulence was encountered, they were thrown initially upward, and then deposited into various positions on the floor and seats. Passengers who had not fastened their seat belts were also thrown vertically upward, and then back down. The flight was provided priority handling for landing, and landed at Atlanta without further incident. According to the flight attendants the flight had encountered "a little chop" while climbing. The "fasten seatbelt" sign was off until they encountered an area of moderate turbulence when the "fasten seatbelt" sign came on and the captain made an announcement. The sign did not go out for the remainder of the flight. The flight attendants had just finished the beverage service and the galley carts were being restocked. The airplane "buffeted for 4-6 seconds." Three flight attendants in the aft galley were "pretty badly hurt." Five flight attendants and three passengers were transported to area hospitals for their injuries.

NTSB Probable Cause Narrative

an in-flight encounter with turbulence in clouds during a normal descent, resulting in serious injuries.
