Airworthiness Directives; McDonnell Douglas Model DC-9-81 (MD-81), DC-9-82 (MD-82), and DC-9-83 (MD-83) Airplanes, and Model MD-88 Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-9-81 (MD-81), DC-9-82 (MD-82), and DC-9-83 (MD-83) airplanes, and Model MD-88 airplanes, that requires an inspection of the disconnect panel area above the aft left lavatory for chafed or damaged wires or unacceptable clearance between the wires and adjacent structure, and corrective actions, if necessary. The actions specified by this AD are intended to prevent chafing of wires at the disconnect panel above the aft left lavatory, which could result in electrical arcing, and consequent fire in the cabin. This action is intended to address the identified unsafe condition.
