This is what cheap non-union labor gets you.

Even when Boeing has its best month in years, it has problems.

Boeing on Tuesday disclosed a new issue with the 787 Dreamliner widebody jet, which has been dogged with problems since August. The company said some of the planes' fuselage was not joined together to meet precise standards and there are questions about the verification process to make sure they meet the standards.

The locations where parts of the plane are joined must meet precise standards down to a small fraction of an inch. There are questions about the inspection process used to check that work.

The company said it has been working with the FAA on the problem and identified a way to fix the 787s that haven't yet been delivered to customers. Boeing said 787 planes already in service do not need to be grounded.

Boeing moved its entire 787 production to South Carolina last year.
