## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A300 B4-605R airplanes and Model A310-308, -324, and -325 airplanes. This AD requires modifying the Bruce floor plan electrical emergency path marking system (FPEEPMS) and, for certain airplanes, modifying the automatic switching of the emergency lighting system. This AD results from a report that in the case of vertical separation of the fuselage forward of door 1, the FPEEPMS and the exit signs do not turn on. We are issuing this AD to prevent inadequate lighting and marking of the escape path, which could delay or impede the flightcrew and passengers when exiting the airplane during an emergency landing.
