Boeing Co quality inspections related to previously disclosed production flaws in its 787 Dreamliner found the same issue in other parts of the jet, the company said on Monday.
Boeing said earlier this month that inspections for 787 production flaws were taking longer than expected, hampering the United States plane manufacturer’s ability to deliver jets to customers through December.

On Monday, Boeing added that inspections of assembled 787 aircraft found that some areas where fuselage segments are joined were potentially not as smooth as required.
The engineering specifications at issue are roughly equivalent to the width of a human hair, the company noted.
Boeing also said the problem does not pose an imminent safety hazard.
The specific reason behind the broader quality-control checks, and the fact that they now cover areas where large sections of the fuselage come together rather than just certain sections around the jet’s tail, was earlier reported by the Wall Street Journal newspaper.
The US Federal Aviation Administration (FAA) said in a statement on Monday that it “continuously engages with Boeing through established Continued Operational Safety and manufacturing oversight processes to appropriately address any issues that might arise.”
An FAA official told the Reuters news agency that “none of the issues raised recently are considered to be immediate safety concerns,” adding that it “takes these quality concerns seriously and continues to be involved in the discussions about any mitigations”.
