Description

A Hong Kong Airlines Airbus A330, registration B-LHA, enroute from Beijing to Hong Kong encountered turbulence. The aircraft was in turbulence thirty minutes prior to the estimated time of arrival (ETA) when the Captain informed the cabin crew manager that the weather in Hong Kong was bad and to prepare the cabin for an early arrival. During the cabin crew pre-landing checks, while the seat belt sign for turbulence was illuminated, the aircraft encountered turbulence and the Captain made a public announcement ?Cabin crew please take your seats?. The vertical turbulence led to the vertical load factor to increase up to +1.75G before decreasing to +0.35G During the turbulence encountered, one of the cabin crew sustained a lower leg injury. There was no damage to the aircraft. The aircraft landed at Hong Kong International Airport. The injured cabin crew was immediately sent to airport clinic for medical treatment after landing, and subsequently transferred to North Lantau Hospital where the injury was diagnosed as closed fracture of the right foot.
