The Federal Aviation Administration, despite receiving several warning about suspected problem with some parts which have been known to cause rare shutdowns midair, has decided that it will allow more than 130 Boeing 777 airplanes to continue undertaking international trips till early 2011.

The FAA in July had ordered Boeing to upgrade some of its jets, which sport Rolls Royce brand engines, by installing redesigned cooling systems by January 2011, which would help prevent the accumulation of ice on the insides of fuel system's pipes. The deadline has been set for much later as the replacement parts are reportedly available in limited quantities.

The FAA has reportedly claimed that "interim operational safeguards that were previously imposed provided an adequate safety margin to put off permanent hardware fixes until January 2011".

Recently, the FAA had said no to recommendations by the National Transportation Safety Board to order the required parts so that at least one of the two engines that the planes sport can be fixed.

FAA has so far decline to not comment on the decision, and even Boeing has not said anything yet.
