FLT ATTENDANT IS INJURED WHEN THE MLG ENCOUNTERED WAKE TURB BEHIND A WDB.

Narrative

WE WERE 13 DME S OF CRI ON A HDG TO INTERCEPT THE 223 DEG RADIAL INBOUND FOR THE VOR 13L APCH. WE GAVE THE FLT ATTENDANTS A SIGNAL (3 BELLS) TO PREPARE THE CABIN FOR LNDG AND BE SEATED. WE JOINED THE FINAL APCH COURSE INBOUND AT 3000 FT THEN DSNDED TO CROSS CRI AT 1500 FT. WE WERE CAUTIONED THAT WE WERE FOLLOWING A WDB AND CAUTIONED ABOUT WAKE TURB. JUST AFTER PASSING CRI AND PRIOR TO LEAVING 1500 FT WE ENCOUNTERED WAKE TURB; WHICH BANKED THE AIRPLANE 45 DEGS (APPROX) TO THE R. WE LEVELED OUR WINGS; THEN RECEIVED A RPT THAT THE FLT ATTENDANT IN THE REAR OF THE PLANE HAD BEEN INJURED. (SHE WAS THE ONLY FLT ATTENDANT NOT SEATED AT THE TIME.) WE CALLED FOR AN AMBULANCE; THEN CONTINUED THE APCH WITHOUT FURTHER INCIDENT. THE FLT ATTENDANT SUSTAINED A 1/2 INCH CUT ABOVE HER R EYEBROW WHICH REQUIRED SEVERAL STITCHES. SHE SUFFERED SEVERAL BRUISES ON HER HEAD AND LEGS AS WELL. I FEEL THIS INCIDENT COULD HAVE BEEN AVOIDED IF THE CABIN CHK HAD BEEN ACCOMPLISHED AT 10000 FT AND THE FLT ATTENDANTS HAD BEEN SEATED IMMEDIATELY WHEN SIGNALED.
