A three-year French investigation into a near-catastrophic Airbus SE A380 engine blowout over Greenland found hidden weaknesses in the structure of a widely used metal alloy, with safety implications for plane equipment worldwide.
Microscopic cracks beneath the surface of a titanium alloy caused one engine on an Air France superjumbo to break apart during a flight between Paris and Los Angeles on Sept. 30, 2017, France’s air-crash authority, Bureau d’Enquetes et d’Analyses, said in a presentation of the accident report on Tuesday.
