## Abstract

We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This AD was prompted by a report of corrosion found during the manufacturing process for some oxygen pipe assemblies that are used to supply oxygen to the flightcrew. This AD requires an inspection to determine the batch number or installation date of the oxygen pipe assembly that is installed at the end of the right-hand crew distribution line, and, if necessary, replacement of the pipe. We are issuing this AD to detect and correct corrosion, which could lead to blocked or reduced oxygen supply to a flightcrew member during a decompression event or a smoke/ fire event in the cockpit. Under certain conditions, corrosion particles could increase the risk of fire in the cockpit.
