Technical issue delays delivery of Boeing’s 787 Dreamliner

Boeing Co warned on Tuesday of delays in deliveries of its 787 Dreamliner, as three separate production flaws over the past year hamper efforts to develop an alternative cash cow to its grounded 737 MAX.

In the latest issue, Boeing learned during fabrication of the 787 horizontal stabilizer that some components were clamped with greater force than specified, which could result in improper gap verification and shimming. Boeing identified the problem in February and announced it on Tuesday.

The Federal Aviation Administration (FAA) said Tuesday it “is investigating manufacturing flaws affecting certain Boeing 787 jetliners. The agency continues to engage with Boeing.”

A person briefed on the matter said the horizontal stabilizer issue could require the inspection of as many as about 900 airplanes.
