The National Transportation Safety Board (NTSB) (Washington) has issued an urgent safety recommendation for the redesign of the Rolls-Royce engine component of Boeing 777 during the next maintenance cycle or within the next six months. This recommendation comes after its investigation of two 777 engine failure incidents, the January 17, 2008 dual-engine failure and crash at Heathrow Airport of a British Airways Triple Seven and a November 26, 2008 single engine failure involving a Delta Air Lines 777-232 ER en route from Shanghai to Atlanta over Montana. It will now be up to the Federal Aviation Administration (FAA) to accept and implement the recommendation.
