Docket No. FAA-2026-3475
Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This AD was prompted by a manufacturing investigation that found improper application of the fastener retorque process at the center wing box (CWB) and belly fairing (BF) junctions could lead to insufficient clamping. This AD requires replacing each affected part and applying additional head nut cap protection. The FAA is issuing this AD to address the unsafe condition on these products.
