Airworthiness Directive · Amendment 39-18600 · Oxygen
Airbus Airplanes
This AD applies to the airplanes identified in paragraphs (c)(1), (c)(2), (c)(3), and (c)(4) of this AD; certificated in any category; all manufacturer serial numbers, except those that have embodied Airbus modification 33125 (gaseous system for all oxygen containers) in production.
(1) Airbus Model A318-111, -112, -121, and -122 airplanes.
(2) Airbus Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes.
(3) Airbus Model A320-211, -212, -214, -231, -232, and -233 airplanes.
(4) Airbus 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 reports of premature aging of certain passenger chemical oxygen generators that resulted in the generators failing to activate. This AD requires an inspection to determine if certain passenger chemical oxygen generators are installed and replacement of affected passenger chemical oxygen generators. We are issuing this AD to prevent failure of the passenger chemical oxygen generator to activate and consequently not deliver oxygen during an emergency, possibly resulting in injury to the airplane occupants.
Within 30 days after the effective date of this AD: Do a one-time inspection of passenger chemical oxygen generators, part numbers (P/N) 117042-02 (15 minutes (min)—2 masks), 117042-03 (15 min—3 masks), 117042-04 (15 min—4 masks), 117042-22 (22 min—2 masks), 117042-23 (22 min—3 masks), and 117042-24 (22 min—4 masks) to determine the date of manufacture as specified in Airbus Alert Operators Transmission (AOT) A35N006-14, dated December 10, 2014, including Appendix 1. Refer to figures 1 and 2 to paragraph (g) of this AD for the location of the date. A review of airplane maintenance records is acceptable for the inspection required by this paragraph, provided the date of manufacture can be conclusively determined by that review.
If, during any inspection required by paragraph (g) of this AD, any passenger chemical oxygen generator having a date of manufacture in 1999, 2000, or 2001 is found: At the applicable time specified in paragraph (h)(1), (h)(2), or (h)(3) of this AD, remove and replace the affected passenger chemical oxygen generator with a serviceable unit, in accordance with Airbus AOT A35N006-14, dated December 10, 2014, including Appendix 1 (for 15-minute and 22-minute passenger chemical oxygen generators); or the Accomplishment Instructions of B/E Aerospace Service Bulletin 117042-35-001, Revision 004, dated October 13, 2015 (for 15-minute passenger chemical oxygen generators).
(1) For passenger chemical oxygen generators that have a date of manufacture in 1999: Within 30 days after the effective date of this AD.
(2) For passenger chemical oxygen generators that have a date of manufacture in 2000: Within 6 months after the effective date of this AD.
(3) For passenger chemical oxygen generators that have a date of manufacture in 2001: Within 12 months after the effective date of this AD.
If, during any inspection required by paragraph (g) of this AD, any passenger chemical oxygen generator having a date specified in table 1 to paragraph (i) of this AD is found: At the applicable time specified in table 1 to paragraph (i) of this AD, remove and replace the affected passenger chemical oxygen generator with a serviceable unit, in accordance with Airbus AOT A35N006-14, dated December 10, 2014, including Appendix 01, undated (for 15-minute and 22-minute passenger chemical oxygen generators); or the Accomplishment Instructions of B/E Aerospace Service Bulletin 117042-35-001, Revision 004, dated October 13, 2015 (for 15-minute passenger chemical oxygen generators).
| Year of manufacture | Compliance time |
|---|---|
| 2002 | Within 12 months after the effective date of this AD. |
| 2003 | Within 16 months after the effective date of this AD. |
| 2004 | Within 20 months after the effective date of this AD. |
| 2005 | Within 24 months after the effective date of this AD. |
| 2006 | Within 28 months after the effective date of this AD. |
| 2007 | Within 32 months after the effective date of this AD. |
| 2008 | Within 36 months after the effective date of this AD. |
| 2009 | Before exceeding 10 years since date of manufacture of the passenger chemical oxygen generator. |
For the purpose of this AD, a serviceable unit is a passenger chemical oxygen generator having P/N 117042-XX with a manufacturing date not older than 10 years, or any other approved part number, provided that the generator has not exceeded the life limit established for that generator by the manufacturer.
At the applicable time specified in paragraph (k)(1) or (k)(2) of this AD, submit a report of the findings (both positive and negative) of the inspection required by paragraph (g) of this AD, in accordance with paragraph 7, “Reporting,” of Airbus AOT A35N006-14, dated December 10, 2014, including Appendix 1. The report must include the information specified in Appendix 1 of Airbus AOT A35N006-14, dated December 10, 2014.
(1) If the inspection was done on or after the effective date of this AD: Submit the report within 30 days after the inspection.
(2) If the inspection was done before the effective date of this AD: Submit the report within 30 days after the effective date of this AD.
As of the effective date of this AD, no person may install a passenger chemical oxygen generator, unless it is determined, prior to installation, that the oxygen generator is a serviceable unit as specified in paragraph (j) 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.
