Built by the Tribune's code from the Federal Register. No AI wrote this page. Published in the Federal Register Feb. 24, 2026. Document 2026-03612. Updated Nov. 14, 2026.

What it does

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, during production, certain sealant installations within the center wing fuel tank did not receive required visual and adhesion inspections. This proposed AD would require 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 proposing this AD to address the unsafe condition on these products.
