## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

THE AIRCRAFT WAS AT FLIGHT CRUISE LEVEL 300.  THE SEATBELT SIGN WAS ILLUMINATED AND PASSENGERS WERE SEATED WITH SEATBELTS FASTENED.  FLIGHT ATTENDANTS HAD BEEN ADVISED BY THE FLIGHT CREW OF  TURBULENCE IN THE AREA AND INSTRUCTED TO REMAIN NEAR THEIR JUMPSEATS.  THE FLIGHT SUBSEQUENTLY ENCOUNTERED SEVERE TURBULENCE ESTIMATED TO HAVE LASTED 30 SECONDS.  ONE OF THE FLIGHT ATTENDANTS WAS IN THE LAVATORY WHEN THE TURBULENCE OCCURRED AND REPORTED A POSSIBLE SPRAINED ANKLE.  THERE WERE NO OTHER REPORTED INJURIES TO PASSENGERS OR CREWMEMBERS.  AFTER THE FLIGHT, MEDICAL DIAGNOSIS OF THE INJURED FLIGHT ATTENDANT'S ANKLE REVEALED AN ACUTE FRACTURE OF THE RIGHT FIBULA.
