NTSB narrative
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.
Probable cause
An unexpected encounter with turbulence, during the initial descent for landing.

- 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, coordinates, damage. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2008-04-07.
