Airbus Airplanes
This AD applies to Airbus A330-301, A340-211, A340-212, A340-311, A340-312.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes. This action requires replacement of the fire extinguisher distribution pipe and attachments in the lower deck cargo compartment fire extinguishing system. This amendment is prompted by a report indicating that, in response to a smoke warning in the forward cargo compartment on one airplane, bottle 2 of the fire extinguishing system did not discharge extinguishing agent into the cargo compartment due to a blockage of the discharge pipe by debris within it. The actions specified in this AD are intended to ensure that, in the event of a fire, adequate fire extinguishing agent is discharged into the cargo compartment.
