Incident Overview
An airliner on an authorized off-course deviation to circumvent convective activity identified on radar encountered turbulence. The flight was approaching MEGOG intersection at the time. Prior to the encounter, the captain had illuminated the fasten seatbelt light and instructed the chief purser to alert other flight attendants about potential turbulence and to remain seated.
Weather Avoidance Procedures
The deviation from the planned route was authorized to avoid convective weather. The crew had identified the activity on radar and took precautionary measures. Approximately ten minutes after the captain's warning, at MEGOG intersection, the aircraft encountered three to five seconds of turbulence, described by the captain as moderate-to-severe. The weather radar was active during the encounter; however, no weather returns were displayed.
Turbulence Encounter
During the turbulence, one flight attendant was not seated and had not received the prewarning. This flight attendant was attending to a passenger call. According to passenger reports, the flight attendant left the floor of the aircraft at the onset of turbulence and landed hard on her shoulder and side.
Injuries
Medical examination later determined that the flight attendant suffered a hairline fracture of the right clavicle as a result of the encounter. No other injuries were reported.
Aftermath
The incident highlights the importance of ensuring all crew members are seated during turbulence, especially when warnings are issued. The source provides no further details on subsequent actions or investigations.
