Airworthiness Directive · Amendment 39-18394 · Oxygen
Airbus Airplanes
This AD applies to the airplanes, certificated in any category, identified in paragraphs (c)(1) and (c)(2) of this AD, all manufacturer serial numbers; except those on which a gaseous system for all oxygen generators is installed.
(1) Airbus Model A330-201, -202, -203, -223, -223F, -243, -243F, -301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes.
(2) Airbus Model A340-211, -212, -213, -311, -312, -313, -541, and -642 airplanes.
We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200, -200 Freighter, and -300 series airplanes, and all Airbus Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by reports of premature aging of certain chemical oxygen generators in the passenger compartment that resulted in failure of the generators to activate. This AD requires inspecting to determine if certain passenger chemical oxygen generators are installed, and replacement of affected generators. We are issuing this AD to prevent failure of the chemical oxygen generator to activate during an emergency situation, which could result in unavailability of oxygen and possible incapacitation of the occupants.
Within 30 days after the effective date of this AD: Inspect each passenger chemical oxygen generator to identify the date of manufacture (refer to figures 1 and 2 to paragraph (g) of this AD for the location of the date) of each passenger chemical oxygen generator having any part number (P/N) listed in paragraphs (g)(1) through (g)(6) of this AD, in accordance with the Instructions of Airbus Alert Operators Transmission (AOT) A35L007-14, Revision 01, June 17, 2015, including Appendix A, Revision 01, dated June 17, 2015. A review of airplane maintenance records is acceptable in lieu of this inspection if the date of manufacture of the generator can be conclusively determined from that review.
(1) 117042-02 (15 minutes (min)—2 masks).
(2) 117042-03 (15 min—3 masks).
(3) 117042-04 (15 min—4 masks).
(4) 117042-22 (22 min—2 masks).
(5) 117042-23 (22 min—3 masks).
(6) 117042-24 (22 min—4 masks).
If, during any inspection required by paragraph (g) of this AD, any passenger chemical oxygen generator having a date of manufacture of 1999, 2000, or 2001 is found: At the time specified in paragraph (h)(1), (h)(2), or (h)(3) of this AD, as applicable, replace the affected passenger chemical oxygen generator, in accordance with the Instructions of Airbus AOT A35L007-14, Revision 01, June 17, 2015; including Appendix A, Revision 01, dated June 17, 2015 (for 15- and 22-minute passenger chemical oxygen generators); or in accordance with the Accomplishment Instructions of B/E Aerospace Service Bulletin 117042-35-001, dated December 10, 2014 (for 15-minute passenger chemical oxygen generators).
(1) For units manufactured in 1999: Within 30 days after the effective date of this AD.
(2) For units manufactured in 2000: Within 6 months after the effective date of this AD.
(3) For units manufactured 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 of manufacture of 2002 or later is found: At the time specified in paragraph (i)(1), (i)(2), (i)(3), (i)(4), (i)(5), (i)(6), (i)(7), or (i)(8) of this AD, as applicable, replace the affected passenger chemical oxygen generator with a serviceable unit, in accordance with the Instructions of Airbus AOT A35L007-14, Revision 01, June 17, 2015; including Appendix A, Revision 01, dated June 17, 2015 (for 15- and 22-minute passenger chemical oxygen generators); or in accordance with the Accomplishment Instructions of B/E Aerospace Service Bulletin 117042-35-001, dated December 10, 2014 (for 15-minute passenger chemical oxygen generators).
(1) For units manufactured in 2002: Within 12 months after the effective date of this AD.
(2) For units manufactured in 2003: Within 16 months after the effective date of this AD.
(3) For units manufactured in 2004: Within 20 months after the effective date of this AD.
(4) For units manufactured in 2005: Within 24 months after the effective date of this AD.
(5) For units manufactured in 2006: Within 28 months after the effective date of this AD.
(6) For units manufactured in 2007: Within 32 months after the effective date of this AD.
(7) For units manufactured in 2008: Within 36 months after the effective date of this AD.
(8) For units manufactured in 2009 or later: Before the accumulation of 10 years since date of manufacture.
A serviceable unit is an oxygen generator having P/N 117042-XX, with a manufacturing date not older than 10 years, or any other FAA-approved part number, provided that the generator has not exceeded the life limit established by the manufacturer for that generator.
