AD FAA-2026-1322

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 a report that, during production, certain sealant installations within the center wing fuel tank did not receive required visual and adhesion inspections. This AD requires a detailed inspection of certain sealant installations in the left, right, and center wing side-of-body areas, an adhesion test of the sealant, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
