NTSB determines cause of BA 777 engine fire at Las Vegas

The US National Transportation Safety Board’s (NTSB) second update on the engine failure of British Airways Boeing 777 GE90 on a Las Vegas runway Sept. 8 shows that the failure occurred in the high-pressure compressor (HPC) of the engine.

“Engine examination revealed that a portion of the stage 8-10 spool in the high-pressure compressor section had failed, liberating fragments that breached the engine case and cowling,” NTSB said. “Additional pieces of the HPC spool were recovered from inside the engine and retained for metallurgical examination … The fracture initiated in the HPC stage 8 disk web, a part of the stage 8-10 spool.”

GE is conducting inspections of HPC hardware from other GE90 engines to gather data that will be used to support NTSB’s investigation of the British Airways incident.
