Boeing is investigating a quality issue with its undelivered 787 Dreamliner airplanes. According to reports, hundreds of bolts were incorrectly installed on the fuselages of some planes, with the fasteners torqued from the wrong side. Reuters initially reported the issue, citing people familiar with the situation. Boeing acknowledged the problem and is investigating the root cause and the required rework.

The company has notified the Federal Aviation Administration (FAA) and is working with them to determine necessary actions and ensure a swift resolution. The FAA has additionally begun its own inquiry. Boeing indicated no urgent flight safety concerns, and the fleet can continue operating safely. The company ensures that all airplanes meet delivery requirements before they are delivered.

This is the latest in a string of manufacturing challenges for Boeing, which has recently experienced problems with quality as well as production delays. Boeing is working to solve these concerns and enhance its manufacturing procedures. While it is unclear how many Dreamliners are affected, Boeing has stated that deliveries have not been halted and is examining any potential impact on future deliveries.
