AN A320 ENTERS MODERATE TURB RESULTING IN A CABIN ATTENDANT INJURY. THE FLT CREW PREVIOUSLY TOLD THE CABIN ATTENDANTS TO BE SEATED.

Narrative

WE HAD A FLT ATTENDANT INJURED FROM TURB ON THE WAY TO IAD. AROUND 80 MI W OF DRUZZ INTXN; WE ADVISED THE 'A' FLT ATTENDANT THAT THEY HAD 10-15 MINS OF SMOOTH AIR BEFORE ENCOUNTERING AN AREA OF WX AHEAD AND ON THE APCH TO IAD. WE ASKED THEM TO GET EVERYTHING PUT AWAY; AND GET SEATED BEFORE WE GOT INTO THE WX. ABOUT 5 MINS LATER; MY FO GAVE THE 'PREPARE FOR LNDG' ANNOUNCEMENT. SOME SEVERAL MINS LATER; HE CALLED BACK TO CHK ON THEIR PROGRESS AND GOT NO ANSWER. HE TRIED 3 OR 4 TIMES BEFORE GETTING A RESPONSE THAT 'THEY WERE WORKING ON IT.' I WAS FLYING THE AIRPLANE AND TALKING TO ATC WHILE HE WAS DEALING WITH THEM. AS WE APCHED THE 'WX;' OUR RADAR WAS PAINTING A LOT OF CELL ACTIVITY ON EITHER SIDE OF OUR DSCNT PATH; BUT OUR RTE WAS QUITE CLR OF ECHOES. WE WERE QUITE CONFIDENT THAT OUR RIDE WOULD BE PRETTY DECENT AS WE WENT IMC. A FEW MI E OF DRUZZ; AS WE WERE DSNDING OUT OF 10000 FT; AND AT 250 KTS; WE ENCOUNTERED MODERATE TURB ASSOCIATED WITH CUMULUS CLOUDS THAT WERE NOT PAINTING ON THE RADAR. WE ONLY SAW THEM AT THE VERY LAST SECOND AND COULD NOT AVOID THEM. WE WENT THROUGH THEM WITH THE ASSOCIATED MODERATE BUMPS AND THEN WE WERE CLR THE REST OF THE WAY TO THE ARPT. MY FO CALLED TO THE BACK TO SEE IF EVERYONE WAS SEATED AND OK. THE 'A' FLT ATTENDANT REPLIED THAT SHE WAS SEATED AND OK BUT DID NOT KNOW ABOUT THE BACK CABIN. WE HEARD NOTHING MORE FROM THE CABIN UNTIL WE WERE ON THE TXWY ABOUT TO ENTER THE S RAMP FOR PARKING. ONE OF THE FLT ATTENDANTS (NOT EVEN SURE WHO) CALLED AND SAID THAT IN FACT; WE DID HAVE AN INJURED FLT ATTENDANT FROM THE TURB AND THAT MEDICAL ASSISTANCE WAS REQUESTED. WE ASKED FOR THE PARAMEDICS RIGHT AWAY AND THEY MET THE ACFT A FEW MINS AFTER PARKING. THE INJURED FLT ATTENDANT WAS EVIDENTLY STILL UP DOING THE LIQUOR PAPERS WHEN WE HIT THE BUMPS AND WAS SENT TO THE FLOOR ON HER TAILBONE. THE PARAMEDICS CAME ONBOARD APPROX HALFWAY THROUGH THE DEPLANING OF PAX AND PROCEEDED TO THE REAR GALLEY WITH A BOARD STRETCHER. THEY REQUESTED A GALLEY TRUCK TO THE BACK DOORS TO BE ABLE TO COMFORTABLY REMOVE THE INJURED FLT ATTENDANT AND GET HER ONTO THE AWAITING RESCUE VEHICLE. SHE WAS TRANSPORTED; I BELIEVE; TO A LCL HOSPITAL. I CALLED AROUND XA00 THE NEXT MORNING TO CHK ON HER; BUT FOUND THAT SHE HAD ALREADY BEEN RELEASED.
