Flight 432 encountered about 30 seconds of moderate turbulence while deviating around weather cells during a descent from 17,000 feet mean sea level (msl). The seat belt sign was on and the flight attendants were instructed to be seated prior to the encounter. The 'A' flight attendant in the front of the airplane was able to get to her jumpseat. The 'B' and 'C' flight attendants in the back of the airplane were not seated and both were thrown to the ceiling during the encounter. The 'B' flight attendant suffered a cut and bruises. The 'C' flight attendant who landed on the floor suffered a broken pelvis.
Probable Cause: the flight attendants did not follow the cockpit crews instructions to be seated because of expected turbulence. A factor associated with the accident was the turbulence encountered.
