Boeing grounded eight of its 787 Dreamliner jets for inspection and repair after finding two manufacturing flaws that together could compromise the structural integrity of the aircraft.
The distinct issues involve the composite barrel sections at the rear of the wide-body plane, which are melded together at a Boeing plant in South Carolina. Together, the flaws cause the fuselage sections to fall short of the planemaker’s standards for withstanding stress, creating a risk of in-flight failure.
Boeing has found that the rest of the global Dreamliner fleet meets those standards, known as limited load capability, a person familiar with the matter said. However, Boeing is analyzing data to determine whether it needs to take further action such as recommending inspections of other Dreamliners in use, said the person, who asked not to be identified as the matter is confidential.
Air Canada, United Airlines and Singapore Airlines said they each had one of the affected planes. United said its Dreamliner had been in service before the airline was notified by Boeing.
