## Abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-9-81, -82, -83, and -87 series airplanes, and Model MD-88 airplanes, that currently requires an inspection to detect damage, burn marks, or discoloration at certain electrical plugs and receptacles of the sidewall lighting in the passenger cabin, and correction of discrepancies. That AD also requires modification of the electrical connectors, which terminates the inspection requirement. That action was prompted by reports of failures of the electrical connectors in the sidewall fluorescent lighting, which resulted in smoke or lighting interruption in the passenger cabin. This amendment expands the applicability of the existing AD to include additional airplanes. This amendment is intended to prevent failures of the electrical connectors, which could result in poor socket/pin contact, excessive heat, electrical arcing, and subsequently, connector burn-through and smoke and/or fire in the passenger cabin.
