In January 2008, a Boeing 777 crash landed just short of the runway at London Heathrow Airport. Ice crystals had formed in the fuel. The ice crystals restricted the fuel to the aircraft’s two Rolls-Royce engines, causing a power failure just before landing.
Could the same thing have happened to Asiana Airlines Flight 214?
First, after the crash at Heathrow, the Rolls Royce engine components that had iced up were re-designed so that it could not happen again.
Second, Asiana 214’s engines were not Rolls Royce Engines. Rather, they were Pratt & Whitney engines. Pratt & Whitney engines heat the fuel before passing it through the components that would otherwise be susceptible to icing up.
Finally, witnesses on board the aircraft report that the pilot increased throttle to what seemed to be full takeoff thrust just before the crash. If ice crystals had somehow restricted the fuel flow, that would not have been possible.
