While cruising at FL310, the captain observed on radar that the airplane was approaching a line of thunderstorm cells, which had been forecast. The captain advised the first flight attendant to expect turbulence. He turned on the fasten seat belt sign, and he directed that cabin service be suspended and the service carts stowed. The first flight attendant notified the other flight attendants of the captain's instructions. She stated that she directed them to "stop service and take their seats immediately." The flight attendants secured the cabin, which took a few minutes. However, they had not taken their seats when the airplane encountered several jolts of moderate turbulence. The airplane's flight data recorder indicated that within a 1/2-second period the vertical acceleration changed from -0.05G to 2.37Gs. The first flight attendant (front cabin) was knocked off her feet. The three flight attendants in the aft galley were thrown upward but did not strike the ceiling before coming back down and falling to the floor. One was seriously injured. The operator's "InFlight Operations Manual" required the flight crew to use standard terminology during briefings to the flight attendants. The descriptive terms include usage of the words "light, moderate, or severe" when describing expected turbulence. Neither the captain nor any of the flight attendants reported having used/heard these terms regarding the anticipated turbulence intensity.
Probable Cause: The en route cruise encounter with forecast moderate turbulence.
