PA,
Thanks for the link.
In that article there is also an additional issue;
Quote, "In the latest, unrelated to the aforementioned issues, blow, the FAA mandated checks on 222 US-registered 787s. The agency identified that bilge barriers in the forward and aft cargo areas of the Dreamliner were either damaged or disengaged, as potentially, a fire in the cargo compartments “could result in the loss of continued safe flight and landing of the airplane.”
It isn't clear if the bilge barriers were part of a production issue which brings into question QC or lack thereof.
