SEATTLE (AP) -- Chicago-based Boeing Co. has alerted airlines that Rolls Royce Trent engines in more than 200 777s could experience icing problems.
The Seattle Post-Intelligencer reports that the notice was sent Thursday. The notice suggests in-flight precautions to avoid ice buildups in fuel lines that can cut power in unusually cold weather.
The notice covers about 30 percent of the more than 700 777s in use.
Two episodes were cited.
In January 2008, seven passengers were injured when a British Airways 777 made a hard landing at Heathrow Airport outside London. Both engines failed to respond to a command for thrust.
In November, a Delta Airlines 777 on a flight from Shanghai to Atlanta lost power in one engine. Power was regained after the pilot descended.
