Oct 19. After crossing the Atlantic Ocean and reaching Brazilian airspace, Aerolíneas Argentinas flight AR1133 encountered severe turbulence, leading twelve passengers to suffer from severe injuries. A few passengers were taken to Hospital de Ezeiza for treatment and observation. There were 271 passengers onboard and 13 crew on the Airbus A330.
The turbulence was so severe that some emergency equipment fell from the ceiling, and some overhead panels cracked. Because of the situation, the crew requested that medical service meet the plane in Buenos Aires, and nine passengers were treated onsite. A further three passengers were taken to the hospital with minor injuries.
“According to the information provided by the crew, the ‘fasten seatbelt’ signs were on, and an announcement had been made. The passengers who suffered most and were taken to the hospital did not have their seatbelts fastened when the aircraft encountered turbulence.” – Aerolíneas Argentinas
But according to a passenger on flight AR1133 who was interviewed by Argentinian media outlet Clarin, the ‘fasten seatbelt’ sign had not been turned on.
