Airworthiness Directive · Amendment 39-14662 · Boeing Model 747-400 and 747-400D Series Airplanes
Boeing Model 747-400 and 747-400D Series Airplanes
This AD applies to Boeing Model 747-400 and 747-400D series airplanes, certificated in any category; as identified in Boeing Special Attention Service Bulletin 747-25-3371, dated July 28, 2005; equipped with center overhead stowage bins.
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.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 60 months after the effective date of this AD, replace specified tie rods of the center overhead stowage bins with new, improved tie rods that meet emergency landing load requirements, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 747-25-3371, dated July 28, 2005.
