Narrative:JAL flight JL514, a Boeing 777-346, encountered severe turbulence at FL300. A cabin attendant fell down and was injured.
PROBABLE CAUSES
In this accident, it is highly probable that the aircraft encountered clear air turbulence while it was passing through the side edge of the jet stream, and because of that the aircraft was so fiercely shaken that the cabin attendant who was on the aft aisle of the aircraft fell down and was injured.
With regard to the encountering of the aircraft with clear air turbulence, it is probable that the existence of VWS region on the flight route of the aircraft, which was stronger than the forecast confirmed prior to the flight, was attributable to the encounter.
