## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-11 series airplanes. This action requires repetitive inspections to verify operation of the remote control circuit breakers (RCCB) of the alternating current (AC) cabin bus switch, and replacement of any discrepant RCCB with a new RCCB. This action is necessary to prevent propagation of smoke and fumes in the cockpit and passenger cabin due to an inoperable RCCB of the AC cabin bus switch during smoke and fume isolation procedures. This action is intended to address the identified unsafe condition.
