Experts have warned there is a "high probability" that a fault which caused a British Airways jet to crash-land at Heathrow could hit other Boeing 777s.*
US air accident investigators called for a component to be redesigned after a Delta Air Lines plane reportedly encountered a similar problem.
Manufacturers Rolls-Royce say the new part should be ready within the year.
There are currently 220 Boeing 777s, with Rolls-Royce Trent 800 engines, in operation. The planes are used by 11 airlines and British Airways owns 15.
