Boeing says it will cut 787 Dreamliner production after finding another production-related structural defect.

America’s aviation watchdog discovered problems with undelivered Boeing Dreamliners, forcing the manufacturer to take swift action.

The Federal Aviation Administration revealed that some undelivered Boeing 787 Dreamliner jets have a manufacturing quality issue impacting the nose of the aircraft.

The issues will likely further delay deliveries of the popular wide-body jets.

The FAA says the issue is “near the nose on certain 787 Dreamliners in the company’s inventory of undelivered airplanes. This issue was discovered as part of the ongoing system-wide inspection of Boeing’s 787 shimming processes required by the FAA.”

It also comes after a major customer partially canceled a 7-3-7 MAX order in a double hit to the U.S. planemaker’s COVID-19 recovery.

Boeing says it plans to fix the issues impacting the nose of the aircraft on the Boeing 7-8-7..

The FAA added that “although the issue poses no immediate threat to flight safety, Boeing has committed to fix these airplanes before resuming deliveries.” The air regulators added after a review of data it “will determine whether similar modifications should be made on 787s already in commercial service

Boeing plans to address and fix the issue before the planes will be delivered

The aircraft manufacturing company has about 100 undelivered 787s in inventory.

Boeing suspended deliveries of the 787 in late May after the FAA raised concerns about its proposed inspection method, saying it was “waiting for additional data from Boeing before determining whether the company’s solution meets safety regulations.”

The FAA in May had issued two airworthiness directives to address production issues for in-service airplanes.
