Analysis

The captain received a company briefing prior to the flt. A convective SIGMET was in effect & turbulence was forcast for the area. During flt, the acft was manuevered to avoid turbulence. The acft was clear of clouds & in a thin haze layer when the crew felt a light bump. The seat belt sign was turned on, the autoplt was disengaged & the throttles were retarded. However, within seconds, the acft was subjected to negative 'g' loading. The flt attendants were completing a beverage service & did not have time to 'strap in.' One flt attendant was seriously injured & 3 others received minor injuries.
