## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Boeing transport category airplanes. This AD requires inspecting to determine if certain galleys and closets are installed, and replacing the spiral wire wrapping of the electrical cables of the galleys and closets with new spiral wire wrapping if necessary. This AD results from testing and reports from the manufacturer indicating unacceptable flammability properties of wire wrapping installed in certain galleys and closets. We are issuing this AD to prevent fire propagation or smoke in the cabin area due to electrical arcing or sparking and ignition of the spiral wire wrapping.
