The FAA has opened a new investigation into a potential manufacturing quality lapse on Boeing's 787 Dreamliner and whether inspection records were falsified.

The FAA has opened an investigation into Boeing’s 787 Dreamliner after the company disclosed that employees in South Carolina falsified inspection records on work done where the wings are joined to the fuselage body.

Boeing informed the Federal Aviation Administration in April that, despite records indicating completion of required inspections, workers had not performed some of those inspections to confirm adequate bonding and electrical grounding at the 787 wing-to-body join.

“The FAA is investigating whether Boeing completed the inspections and whether company employees may have falsified aircraft records,” the federal safety agency said via email.

Boeing said its engineers have established that this newly discovered lapse does not create “an immediate safety of flight issue.”
