The Federal Aviation Administration (FAA) has issued a proposed mandatory airworthiness directive concerning the Boeing 787 series. This action stems from identified fatigue cracks associated with shim gaps and preload forces at key wing and fuselage splice points, potentially affecting the structural integrity of the aircraft. The directive mandates inspections for 17 US-registered Boeing 787s, which are within the initial scope based on production dates.
Boeing previously conducted investigations and issued an alert bulletin in August 2025 to inspect aircraft components for cracks. The manufacturer has confirmed that it resolved the root cause during production and that earlier 787s have cleared for normal operation.
The FAA's scrutiny reflects ongoing industry efforts to enhance safety standards and inspection protocols. Public comments on the proposed directive are being accepted for 45 days, as the agency continues its oversight of Boeing's compliance and safety measures.
