## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model DC-9-10, -20, -30, and -40 series airplanes. This proposal would require rework and reidentification of certain reflector assemblies of the passenger ceiling lights; and installation of a support channel above the reflector, as applicable. This proposal is prompted by reports of heat damaged lamp reflectors and scorched insulation blankets in the main cabin due to the lamps inside the reflectors creating high temperatures. The actions specified by the proposed AD are intended to prevent overheating of the lamp reflectors, which could result in smoke and fire in the main cabin.
