What the agency says
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD was prompted by possible horizontal stabilizer pivot pin lockring, outer pivot pin, and outboard spacer misalignment at final assembly. This AD requires inspection of the left-side and right-side horizontal stabilizer pivot pin assemblies for misalignment and incorrect gapping, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
