## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A318 series airplanes; Model A319-111, A319- 112, A319-113, A319-114, A319-115, A319-131, A319-132, and A319-133 airplanes; Model A320-211, A320-212, A320-214, A320-216, A320-231, A320-232, and A320-233 airplanes; and Model A321-111, A321-112, A321- 131, A321-211, A321-212, A321-213, A321-231, and A321-232 airplanes. This proposed AD was prompted by reports that certain oxygen supply solenoid valves are a potential source of increased flow resistance within the flightcrew oxygen system. This proposed AD would require a detailed inspection (flow test) of certain solenoid valves, and replacement if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
