The safety board said a Delta Airlines 777-200ER, the same model that crashed at Heathrow, was en route from Shanghai to Atlanta when its right engine lost thrust while the plane was cruising at 39,000 feet over Montana on Nov. 26.
Both 777s were powered by Rolls-Royce Trent 895 engines. General Electric also supplies engines for the 777.
On the Delta flight, the pilots followed flight manual procedures and descended to 31,000 feet, where the engine recovered and responded normally, the safety board said. The flight, with 15 crew and 232 passengers, continued to Atlanta, where it landed without further incident. |

Boeing, working with European and U.S. regulators, agreed on several interim measures for Rolls-Royce-powered 777s to reduce the risks of ice causing an engine rollback.
One of those procedures calls for the crew to advance the engine throttles to maximum thrust for 10 seconds before descending on flights that have maintained the same altitude for at least three hours, if the fuel temperature is below 10 degrees Celsius.
The General Electric engines on the 777 have a different fuel system architecture, and Boeing and GE have said the measures adopted after the Heathrow crash only need apply to 777s with the Rolls-Royce Trent engines.
But the UK's Air Accidents Investigation Branch, in its interim report, noted that testing of this "hitherto unknown phenomenon" has only been conducted on 777s with the Trent engines. "It is unknown whether other aircraft and engine types may also be susceptible,'' the safety agency said. |
