## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by possible horizontal stabilizer pivot pin lockring, outer pivot pin, and outboard spacer misalignment at final assembly. This proposed AD would require 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 proposing this AD to address the unsafe condition on these products.
