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 an inspection to detect discrepancies of the wire bundles in the avionics compartment in the vicinity of the pedestal extension area of the First Officer's seat; and corrective actions, if necessary. This action is necessary to prevent chafing of wiring in the avionics compartment, which could result in electrical arcing and consequent smoke and/or fire in the cockpit. This action is intended to address the identified unsafe condition.
