Airworthiness Directive · Amendment 39-18182 · Oxygen
Airbus Airplanes
Superseded. A later AD replaced this one: AD 2019-05-08. Comply with the one in force.
This AD applies to the Airbus airplanes identified in paragraphs (c)(1) through (c)(4) of this AD, certificated in any category, all manufacturer serial numbers.
(1) Model A318-111, -112, -121, and -122 airplanes.
(2) Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes.
(3) Model A320-211, -212, -214, -231, -232, and -233 airplanes.
(4) Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes.
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.
For airplanes identified in paragraph 1.A. of Airbus Service Bulletin A320-35-1069, dated April 26, 2013: Within 7,500 flight hours or 26 months after the effective date of this AD, whichever occurs first, inspect the crew oxygen pipe, having part number (P/N) D3511032000640, to determine the batch number of that pipe, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-35-1069, dated April 26, 2013. A review of airplane maintenance records is acceptable in lieu of this inspection if the batch number of the pipe can be conclusively determined from that review. If the batch number of the oxygen pipe is 19356252, 40008586, 40076689, 40187414, 40292749, 40405164, 40649383, 40724994, 40820410, or 40911832: Within 7,500 flight hours or 26 months after the effective date of this AD, whichever occurs first, replace the oxygen pipe with a serviceable part, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-35-1069, dated April 26, 2013.
For airplanes not identified in paragraph 1.A. of Airbus Service Bulletin A320-35-1069, dated April 26, 2013: Within 7,500 flight hours or 26 months after the effective date of this AD, whichever occurs first, inspect the crew oxygen pipe to determine whether P/N D3511032000640 was installed after June 2011. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number and installation date of the pipe can be conclusively determined from that review. If the pipe was installed after June 2011, or the date cannot be conclusively determined, before further flight, do the actions required in paragraph (g) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
