## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-11 series airplanes. This proposal would require installation of protective sleeving on the right emergency alternating current wire assembly of the overhead switch panel. This action is necessary to ensure that protective sleeving is installed on the right emergency alternating current (AC) wire assembly of the overhead switch panel. Lack of such sleeving could result in loss of redundant electrical power during certain cockpit overhead wiring faults. This action is intended to address the identified unsafe condition.
