Notice of proposed rulemaking (NPRM).

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