'Hairline cracks' were found on the wings of some Dreamliner jets still in production.

Boeing's Dreamliner has hit another snag.

"Hairline cracks" were found on the wings of some jets still in production, the company said Friday.
The aerospace company is inspecting the 40 planes it says may be affected. It will take between one and two weeks to address the issue, wrote spokesman Marc Birtel in an email. He said the company is confident that the problem does not exist for any planes currently in service.
Boeing (BA, Fortune 500) was notified by its supplier Mitsubishi Heavy Industries that a change in its manufacturing process may have led to the cracks. Mitsubishi did not immediately return a call for comment.
