BA jet engine failure uncontained, pieces hit runway: investigators | Reuters
"Initial examination of the left engine revealed multiple breaches of the engine case in the area around the high pressure compressor," the NTSB said in a statement."
Re-stresses the interesting case of Boeing and GE to oppose FAA on insisting on its "unsafe condition" definition in AD 2011-15-06 concerning GE90-85B engines as mentioned in post #188.
If specific failure addressed in this AD would indeed prove to be the origin of the uncontained failure in this case, and of course indeed assuming that BA complied with the inspections pertaining from this AD, then GE and Boeing would have quite some explaining to do, as they in their comments to the FAA at the time ascertained that "....by their analyses, cracks in the weld joint would not develop into an uncontained failure." The FAA disagreed with this at the time and pursued the AD.
