Airworthiness Directive · Amendment 39-19590 · Oxygen
Airbus SAS Airplanes
This AD applies to the Airbus SAS airplanes identified in paragraphs (c)(1) through (c)(5) of this AD, certificated in any category.
(1) Model A318-111, -112, -121, and -122 airplanes, all manufacturer serial numbers.
(2) Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes, all manufacturer serial numbers.
(3) Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes, all manufacturer serial numbers.
(4) Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes, all manufacturer serial numbers.
(5) Model A320-251N, A320-271N, and A321-271N airplanes, manufacturer serial numbers 6101, 6286, 6419, 6642, and 6673.
We are superseding Airworthiness Directive (AD) 2015-12-08, which applied to all Airbus SAS Model A318 and A319 series airplanes and all Model A320-211, A320-212, A320-214, A320-231, A320-232, A320- 233, A321-111, A321-112, A321-131, A321-211, A321-212, A321-213, A321- 231, and A321-232 airplanes. AD 2015-12-08 required 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 replacement of the pipe if necessary. This AD revises the applicability to include additional airplane models and additional pipes to be replaced if necessary. This AD was prompted by further investigation that determined that affected oxygen pipes may have been installed on more airplanes than initially identified. We are issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of paragraph (g) of AD 2015-12-08, with new service information. 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, whichever occurs first after July 21, 2015 (the effective date of AD 2015-12-08), 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; or Airbus Service Bulletin A320-35-1069, Revision 03, dated December 8, 2017. 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, whichever occurs first after July 21, 2015, 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; or Airbus Service Bulletin A320-35-1069, Revision 03, dated December 8, 2017. After the effective date of this AD, only Airbus Service Bulletin A320-35-1069, Revision 03, dated December 8, 2017, may be used to do the actions required by this paragraph.
This paragraph restates the requirements of paragraph (h) of AD 2015-12-08, with no changes. For airplanes identified in paragraphs (c)(1) through (c)(4) of this AD that are 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, whichever occurs first after July 21, 2015 (the effective date of AD 2015-12-08), 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.
This paragraph restates the prohibition specified in paragraph (i) of AD 2015-12-08, with no changes. For airplanes identified in paragraphs (c)(1) through (c)(4) of this AD: As of July 21, 2015 (the effective date of AD 2015-12-08), do not install, on any airplane, a crew oxygen pipe P/N D3511032000640, that is identified as belonging to batch number 19356252, 40008586, 40076689, 40187414, 40292749, 40405164, 40649383, 40724994, 40820410, or 40911832.
For airplanes identified in paragraph (c)(5) of this AD: Within 7,500 flight hours or 26 months, whichever occurs first after the effective date of this AD, inspect the crew oxygen pipe, having P/N D3511032000640, to determine the batch number of that pipe, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-35-1069, Revision 03, dated December 8, 2017. 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, whichever occurs first after the effective date of this AD, replace the oxygen pipe with a serviceable part, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-35-1069, Revision 03, dated December 8, 2017.
For airplanes identified in paragraph (c)(5) of this AD: As of the effective date of this AD, do not install, on any airplane, a crew oxygen pipe P/N D3511032000640, that is identified as belonging to batch number 19356252, 40008586, 40076689, 40187414, 40292749, 40405164, 40649383, 40724994, 40820410, or 40911832.
Although Airbus Service Bulletin A320-35-1069, Revision 03, dated December 8, 2017, specifies to submit certain information to the manufacturer, and specifies that action as Required for Compliance (RC), this AD does not include that requirement.
(1) Where Airbus Service Bulletin A320-35-1069, Revision 03, dated December 8, 2017, specifies the location to flush certain parts with nitrogen as “in the shop,” and specifies that location as RC, this AD does not require that location to be used when flushing the parts.
(2) Where Airbus Service Bulletin A320-35-1069, Revision 03, dated December 8, 2017, specifies to use part number (P/N) AN960C816, and specifies that part number as RC, this AD allows the use of P/N NAS1149C0863R in lieu of P/N AN960C816.
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.
