NTSB: 2nd 787 Engine Found With Cracked Mid-Shaft
CHARLESTON, S.C. (AP) — Inspectors looking into what caused a Boeing 787 Dreamliner engine to fail during a test flight at Charleston International Airport have found a second problematic plane.
The National Transportation Safety Board said Thursday its investigators had found a second engine with a cracked mid-shaft. That engine was installed on a 787 that hadn't yet flown.
Authorities are still investigating a 787 engine failure during a July 28 test.
NTSB investigators earlier this year went to a General Electric plant in Cincinnati where the engine was built. They found that a mid-shaft fractured and are still working to determine why. Investigators are also looking at manufacturing and assembly records for the engine.
Debris from the engine fell on the runway. A small fire ignited, forcing the airport to briefly shut down.
