Boeing Discovers New Defect on 787 Dreamliners
Boeing said Tuesday it has discovered yet another manufacturing issue on the 787 Dreamliner. This time the problem is an attachment fitting on the horizontal tail, referred to as the stabilizer.
The newly-found production hiccup does not pose a flight safety concern, but it will delay deliveries of the jet as mechanics work to fix the defect on current inventory.
“We are inspecting 787s in our inventory for a nonconforming condition related to a fitting on the horizontal stabilizer,” Boeing said in a statement. “The inspections and required rework will affect timing of near-term 787 deliveries.”
The statement that was first reported by CNBC, added that the defect in the tail is “not an immediate safety of flight issue and the in-service fleet may continue to operate.”
The defect is a small, paper-thin gap in the attachment, Boeing said. Such gaps are typically plugged using a filler known as a shim. The shims in the attachment were incorrectly sized so that the gap exceeded the five-thousandths of an inch allowable in the specification.
“Airplanes found to have a nonconforming condition will be reworked prior to ticket and delivery,” Boeing said. “We have notified the FAA and our customers and are keeping them informed of our progress.”
Boeing had paused deliveries of the planes for several weeks in February of this year because of a separate problem on a fuselage component. But they have had multiple issues in previous years as well.
