Summary
This document revises an earlier proposed airworthiness directive (AD), applicable to certain Boeing Model 747-100, -200, and - 300 series airplanes, that would have required an inspection to determine if hinge bolts and nuts are installed in the overhead stowage bins, and the installation of hinge bolts and nuts, if necessary. That proposal was prompted by reports that overhead stowage bins in the passenger compartment have fallen out of position due to missing hinge bolts. This action revises the proposed rule by revising the applicability to include additional airplanes. The actions specified by this proposed AD are intended to ensure that hinge bolts are installed in the overhead storage bins. Missing hinge bolts could result in the overhead stowage bins falling out of position and injuring airplane occupants.
