Second Trent 895 Failure on a Boeing 777

by Braniff on December 20, 2008

US National Transportation Safety Board said it is investigating an incident last month in which a Delta Air Lines 777-200ER experienced an “uncommanded engine rollback in the cruise phase of an intercontinental flight.” DL Flight 18 was over Montana en route from Shanghai to Atlanta on Nov. 26 at about 12:30 p.m. MST when the incident occurred to the No. 2 engine. The aircraft is powered by Rolls-Royce Trent 895s, the same type of engines that powered the British Airways 777 that crash landed at London Heathrow last January after it suffered a dual engine rollback on final approach.

According to NTSB, the crew of the DL jet descended to 31,000 ft. whereupon “the engine recovered and responded normally thereafter” and the crew elected to continue to ATL, where the aircraft landed without further incident. NTSB said flight data recorders and other applicable data and components were retrieved from the aircraft for testing and evaluation. Senior Air Safety Investigator Bill English, who is serving as the US Accredited Representative in the Heathrow accident investigation, is the investigator in charge of the Delta incident. The UK Air Accident Investigations Brach has assigned an Accredited Representative to the Delta case and “is working closely with the NTSB to determine if there are issues common to both events.”
