NTSB Narrative Summary Released at Completion of Accident

The transport-category airplane was in international airspace, cruising at flight level 270 in the vicinity of thunderstorms, when the captain reported that he illuminated the cabin fasten seatbelt sign and ordered the cabin crew to take their seats and remain seated. The airplane then entered an area of continuous moderate turbulence. Fifteen minutes into the turbulence encounter, a passenger who did not have her seatbelt fastened sustained serious injury when she struck the ceiling of the airplane and then the armrest of her seat and the floor. The captain declared a medical emergency and diverted to the nearest airport. The passenger was hospitalized in excess of 48 hours.

NTSB Probable Cause Narrative

The passenger's decision to ignore the fasten seatbelt sign, resulting in serious injury to the passenger during a turbulence encounter.
