## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747-400 series airplanes, that requires installation of strap assemblies on the ceiling panels and rails that support the video monitors. This amendment is prompted by reports of the video monitor ceiling panels falling into the cabin area due to the failure of certain latch assemblies during turbulence. The actions specified by this AD are intended to prevent ceiling panels from falling into the passenger area in the event of failure of certain latch assemblies on the ceiling panels, which could result in consequent injury to the crew and passengers.
