Incident Overview
An aircraft experienced in-flight turbulence, during which a cabin attendant in the aft section sustained an injury. The captain activated the seat belt sign, briefed the in-flight director, and instructed the flight engineer to ensure all cabin attendants were seated.
Crew Communication
Approximately three minutes before the turbulence encounter, the flight engineer informed the forward cabin attendant about the anticipated turbulence and directed her to brief the rest of the cabin crew. After securing part of her galley, the forward cabin attendant only briefed the mid-galley crew, assuming that the in-flight director would inform the remaining crew members.
Response and Aftermath
The in-flight director later stated that by the time the cockpit crew advised of moderate turbulence and instructed everyone to sit, it was too late to take action. The cabin attendants in the aft galley had not received the briefing, and their beverage carts remained unsecured.
Following the incident, the carrier updated its operations manuals with revised crew notification and procedure changes regarding turbulence encounters and other in-flight emergencies.
