“Two manufacturing issues compromised an area of the structure in the rear of the 787 that is unable to withstand the maximum stress that would be experienced by the aircraft in service and could fail.

Boeing earlier this week instructed airlines to pull a batch of eight recently-manufactured 787 Dreamliners from service, prompting their immediate grounding, after the plane maker determined that a manufacturing issue undermined the strength of an area of the jet’s carbon fiber composite structure.

So far, eight 787s — all built in the last few years — have been withdrawn from flying. Aircraft for United Airlines, Singapore Airlines and Air Canada are impacted by the impromptu grounding, according to a person familiar with the situation.”
Any idea which AC frame is at risk?
