Federal regulators propose requiring modifications to the engines of some Boeing 777 jets to prevent ice from forming in fuel lines during long flights, a problem blamed for the crash of a British Airways plane last year.

The work would have to be completed by January 2011.

The Federal Aviation Administration proposed the safety directive Thursday, following a similar move by European regulators. The FAA rule would call for redesigning a system that heats fuel and cools oil in the engines of some Trent engines made by Rolls Royce PLC and installed on some Boeing 777 jets.

Chicago-based Boeing Co. said there are about 50 such planes operating in the United States.
