British Airways Flight 38

British Airways Flight 38 was a scheduled international passenger flight from Beijing Capital International Airport in Beijing, China to London Heathrow Airport in London, United Kingdom. On 17 January 2008, the Boeing 777-200ER aircraft operating the flight crashed just short of the runway while landing at Heathrow. There were no fatalities. Of the 152 people on board, 47 sustained injuries, one serious. It was the first time in the aircraft type's history that a Boeing 777 was declared a hull loss and subsequently written-off.
The accident was investigated by the Air Accidents Investigation Branch and a final report was issued in 2010. Ice crystals in the jet fuel were blamed as the cause of the accident, clogging the fuel-oil heat exchanger of each engine. This restricted fuel flow to the engines when thrust was demanded during the final approach to Heathrow. The AAIB then identified the rare problem as specific to Rolls-Royce engine FOHEs and Rolls-Royce developed a modification to its FOHE; the European Aviation Safety Agency mandated all affected aircraft to be fitted with the modification before 1 January 2011.
