## Summary

This document revises an earlier proposed airworthiness directive (AD), applicable to all Airbus Model A330 and A340-200, -300, -500, and -600 series airplanes. That action would have required a one- time inspection of each emergency evacuation slide raft installed on Type "A" exit doors equipped with regulator valves having a certain part number to determine if a discrepant regulator valve is installed on the pressure bottle that inflates the slide/raft, and an interim modification of any discrepant valve if necessary. That action also would have required eventual modification of all affected regulator valves, which would have terminated the requirements of the proposed AD. This new action revises the original NPRM by requiring part number identification and a new modification for affected airplanes, removing the one-time inspection and interim modification, and removing certain airplanes from the applicability. The actions specified by this new proposed AD are intended to prevent failure of an emergency evacuation slide raft to deploy and inflate during an emergency situation, which could impede an evacuation and result in injury to passengers or crewmembers. This action is intended to address the identified unsafe condition.
