## Summary

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318, A319, and A321 series airplanes; and Model A320-211, -212, -214, -231, -232, and -233 airplanes. This proposed 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 flight crew. This proposed AD would require 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 proposing this AD to detect and correct corrosion, which could lead to blocked or reduced oxygen supply to a flight crew 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.
