Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This proposed 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 proposed AD would require replacing each affected part and applying additional head nut cap protection. The FAA is proposing this AD to address the unsafe condition on these products.
