The British Airways aircraft that crashed at Heathrow in January may gave been brought down by ice in the fuel system, an accident report has revealed.
The Air Accident Investigation Branch said the flow of fuel dropped causing the engines to lose power less than a minute before landing.
However, investigators have not discovered how the ice got into the system.
The accident happened on January 17 this year when the aircraft carrying 136 passengers and 16 crew hit the ground just short of the runway before skidding across the grass. The passengers were safety evacuated and 18 needed treatment for minor injuries.
