Inspections of older GE engines on airliners around the world could begin in the coming weeks as investigators learn more about the uncontained engine failure that started a fire on a British Airways jet one month ago in Las Vegas. In an update from the NTSB this week, investigators found that a disk in the high-pressure compressor (HPC) in the 777's left GE90 engine fractured during takeoff roll, propelling pieces into the engine case and cowling. "GE is performing high-priority, focused inspections of HPC hardware from other GE90 engines," the NTSB said. According to a Seattle Times report, GE is examining similar compressors that have been in storage to find clues that would aid field inspections. About 400 similar engines are in service, the report said.
