## 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 a detailed visual inspection of the external power feeder cables in the forward cargo compartment between certain stations to detect chafing or damage; repair, if necessary; and installation of spiral wrap. This proposal is prompted by reports of failure of the external power feeder cable due to being chafed during maintenance. The actions specified by the proposed AD are intended to prevent chafing and damage to external ground power feeder cables, which could result in electrical arcing and consequent structural damage and smoke and fire in the forward cargo compartment.
