Airworthiness Directives; Airbus Model A330-200 and -300 Series Airplanes, Model A340-200 and -300 Series Airplanes, and Model 340-541 and -642 Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to all Airbus Model A330-200 and -300 series airplanes, Model A340-200 and -300 series airplanes, and Model 340-541 and -642 airplanes. This AD requires identifying the part number of the emergency evacuation slides or slide rafts installed on Type "A" exit doors, and modifying the regulator valves of the slide and slide raft assemblies if necessary. The actions specified by this 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.
