Summary
This document revises an earlier proposed airworthiness directive (AD), applicable to all McDonnell Douglas Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-88 airplanes, that would have required one-time inspections to detect discrepancies of electrical wiring installations in various areas of the airplane, and corrective action if necessary. This new action expands the area to be inspected. The actions specified by this new proposed AD are intended to prevent smoke and fire in various areas of the airplane due to heat damage and/or electrical arcing of improperly installed wiring. The actions specified in this action are intended to address the identified unsafe condition.
