The National Transportation Safety Board says Boeing warned plane owners in 2011 about a flaw in the part that failed and contributed to the engine flying off a UPS plane before it crashed and killed 15 in November but at that point the plane manufacturer didn’t believe it threatened safety.
And this plane was delivered 6 years before they merged with Boeing.
To Thai Airways, yes. It was remodeled by Boeing in 2006 before it was handed over to UPS.
