## 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 a report that cargo liner joint sealing tape could be missing in particular areas on certain airplanes. The absence of this tape could allow a fire to propagate into the cabin. This proposed AD would require a detailed inspection of these areas for the missing tape, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
