## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-400 and 747-400D series airplanes. This AD requires replacing specified tie rods of the center overhead stowage bins. This AD results from manufacturer analysis of the overhead storage bin support structure that demonstrated that the capability of certain existing tie rods does not meet emergency landing load requirements. We are issuing this AD to prevent detachment of the center overhead stowage bins during an extreme forward load event, which could cause injury to passengers and hinder emergency evacuation procedures.
