Engine on United Airlines flight was showing signs of metal fatigue, NTSB says
CNN
The Pratt & Whitney engine that failed minutes into United Airlines flight 328 showed signs of metal fatigue, investigators with the National Transportation Safety Board said during their first public briefing on Monday.
The new finding is perhaps the most significant in the investigation into Saturday's in-flight incident-- one that led United Airlines to ground all of its Boeing 777s powered by PW4000 series engines and prompted federal regulators to reexamine how often the engines should be inspected.More Related News
