Airworthiness Directives; Transport Category Airplanes Equipped with Day-Ray Products, Inc., Fluorescent Light Ballasts

摘要

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to any transport category airplane that is equipped with certain Day-Ray fluorescent light ballasts installed in the upper and/or lower cabin sidewall. This proposal would require a visual inspection to determine the type of fluorescent light ballasts installed in the cabin sidewall, and either the replacement of suspect ballasts or the installation of a protective cover over the ballast. This proposal is prompted by reports of smoke, fumes, and/or electrical fire emitting from the baggage bin of the aft passenger compartment due to the failure of the fluorescent light ballasts. The actions specified by the proposed AD are intended to prevent the potential for a fire in the passenger compartment resulting from failure of the fluorescent light ballast of the cabin sidewall.
