Using cheap non union labor gets you unsafe workmanship
The Boeing Co. has found manufacturing defects on some 787 long-range airliners in areas where parts of the fuselage are joined.
The company said Friday that eight planes must be inspected and repaired before they are allowed to fly, and it contacted the airlines, which removed the planes from service.

Boeing said that it discovered “two distinct manufacturing issues” toward the rear of certain 787s that means the planes don’t meet design standards. The company said it notified the Federal Aviation Administration and is trying to determine the cause of the problem.

“The source of the newly-discovered structural issue has been traced to a mating point inside the aft fuselage between two carbon fiber composite barrels, known as Section 47/48 where the two barrels meet with a large bulkhead that caps the pressurized cabin,” The Air Current reported. “The pieces are fabricated and joined with the aft pressure bulkhead at Boeing’s North Charleston, South Carolina, plant and then delivered for final assembly to the company’s nearby final assembly building or flown to Everett, Washington.”
