## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to all McDonnell Douglas Model MD-11 series airplanes. This action requires a one-time inspection to detect discrepancies of certain wiring and insulation in the cockpit and cabin, and repair, if necessary. This amendment is prompted by test results obtained in support of an accident investigation. The actions specified in this AD are intended to prevent electrical arcing of certain wiring, which could cause a fire and/or smoke in the cockpit or cabin.
