All 777s with same PW engine grounded

A total of 128 Boeing 777 aircraft using the same Pratt& Whitney engine which failed on a flight out of Denver had been grounded, a spokeswoman for the planemaker said on Monday. As well as United Airlines, the PW4000 engine type was also used by Japan's ANA and JAL groups, plus South Korea's Asiana Airlines. In a statement on Sunday, the company recommended that all the aircraft concerned should be grounded as US regulators were investigating the United Airlines flight which was forced to return to Denver airport after one of its engines caught fire and broke up.
