## Abstract

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400, 747-400F, and 747-8F series airplanes. This AD was prompted by reports of failure of the fastener assemblies on the crew access ladder handrails. This AD requires replacing the fastener assemblies. We are issuing this AD to address the unsafe condition on these products.
