## Abstract

The FAA is superseding an existing airworthiness directive (AD), which applies to certain McDonnell Douglas Model DC-9-10, DC-9- 20, DC-9-30, DC-9-40, and DC-9-50 series airplanes. That AD currently requires a one-time inspection at a certain disconnect panel in the left forward cargo compartment to find contamination of electrical connectors and to determine if a dripshield is installed over the disconnect panel, and corrective actions if necessary. This new AD revises the applicability of the existing AD by removing certain airplanes and adding others. This AD results from a report of electrical arcing that resulted in a fire. We are issuing this AD to prevent contamination of certain electrical connectors, which could cause electrical arcing and consequent fire on the airplane.
