## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-9-10, -30, and -40 series airplanes and C-9 airplanes, that requires revising the wiring of the sidewall lights in the forward and aft passenger compartment. The actions specified by this AD are intended to prevent the control switch of the cabin sidewall lights on the forward attendant's panel from overheating, which could result in shorting of the dim, bright, and power terminals, and consequent smoke/fire in the passenger compartment. This action is intended to address the identified unsafe condition.
