NTSB Narrative Summary Released at Completion of Accident

The Boeing 737-800 encountered turbulence while descending for arrival. The pilot flying (captain) stated that 26 minutes before the scheduled landing he asked the flight attendants to prepare the cabin earlier than normal due to convective weather along the route of flight. Ten minutes after the announcement the airplane encountered turbulence. The pilot reported that both of the airplane's weather radar systems were turned on, and were scanning at 40 and 80 miles range respectively. He reported that the returns showed no convective activity in the immediate area. Two flight attendants were in the aft galley area, after having secured the main cabin for landing, when the turbulence was encountered. During the encounter the attendants were thrown to the ceiling and one sustained a fractured ankle.

NTSB Probable Cause Narrative

An unexpected encounter with turbulence, during the initial descent for landing.
