Narrative:
38 MI FROM THE DESTINATION ARPT, THE CAPT NOTIFIED THE F/A TO BE SEATED DUE TO POSSIBLE TURBULENCE ENCOUNTER. AFTER COMPLETING THE APPROACH CHECKLIST, THE F/A WAS GIVEN THE SIGNAL TO PERFORM THE FINAL CABIN CHECK. 9 MI FROM THE ARPT, THE FLIGHT ENCOUNTERED 'A SINGLE STRONG WINDSHEAR' WHICH CAUSED THE F/A TO BE THROWN AGAINST THE CEILING & THEN TO THE FLOOR. AT THE TIME OF THE OCCURENCE, THE AIRPLANE WAS OPERATING WITHIN A WEAK LEVEL I WX RADAR RETURN, WITHIN 6 MI OF A LEVEL II RETURN, AND WITHIN 9 MI OF A VERY STRONG LEVEL IV RETURN. THE OPERATOR'S FLT OPS MANUAL STATES THAT THE CAPT WILL ADVISE THE F/A AS TO WHETHER OR NOT HE/SHE SHOULD BE SEATED WITH THE SEAT BELT FASTENED. IN ADDITION, NEITHER THE FLT OPS MANUAL NOR THE F/A MANUAL GAVE ANY INSTRUCTIONS AS TO WHEN THE F/A SHOULD RESUME HIS/HER DUTIES AFTER BEING TOLD TO BE SEATED, NOR WAS THE CAPT INSTRUCTED TO NOTIFY THE F/A TO RESUME HIS/HER DUTIES.

Probable Cause: THE OPERATOR'S LACK OF ADEQUATE INSTRUCTIONS TO CREWMEMBERS AS TO WHEN FLIGHT ATTENDANTS CAN RESUME CABIN DUTIES AFTER BEING TOLD TO BE SEATED BY THE CAPTAIN.
