FAA orders Dreamliner inspections

The US Federal Aviation Administration (FAA) has issued an Airworthiness Directive seeking to prevent failure of a critical component found on GE GEnx-series engines after one failed on a B787 Dreamliner during ground testing. The source of the failure was determined to be the engines fan mid shaft, which fractured. The directive supersedes an earlier Service Bulletin and requires inspection before further flight, but does not resolve the problem. The cause of the cracking is yet undetermined, but according to the FAA it "is likely due to environmentally assisted cracking; a type of corrosive cracking that is time-dependent."
