Airworthiness Directive · Amendment 39-18524 · Oxygen
Airbus Airplanes
This AD applies to the airplanes identified in paragraphs (c)(1), (c)(2), (c)(3), (c)(4), and (c)(5) of this AD, certificated in any category, all manufacturer serial numbers.
(1) Airbus Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes.
(2) Airbus Model A300 B4-605R and B4-622R airplanes.
(3) Airbus Model A300 F4-605R and F4-622R airplanes.
(4) Airbus Model A300 C4-605R Variant F airplanes.
(5) Airbus Model A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes.
We are adopting a new airworthiness directive (AD) for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300- 600 series airplanes); and Model A310 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 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), or 117042-24 (22 min—4 masks), to determine the date of manufacture, as specified in Airbus Alert Operators Transmission (AOT) A35W008-14, dated December 18, 2014, including Appendix A, undated. Refer to Figure 1 to paragraph (g) of this AD and Figure 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 the Accomplishment Instructions of B/E Aerospace Service Bulletin 117042-35-001, dated December 10, 2014 (for 15 minute passenger chemical oxygen generators); or Airbus AOT A35W008-14, dated December 18, 2014, including Appendix A, undated (for 22 minute passenger chemical oxygen generators); as applicable.
(1) For passenger chemical oxygen generators that have a date of manufacture in 1999: Remove and replace within 30 days after the effective date of this AD.
(2) For passenger chemical oxygen generators that have a date of manufacture in 2000: Remove and replace within 6 months after the effective date of this AD.
(3) For passenger chemical oxygen generators that have a date of manufacture in 2001: Remove and replace 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 the Accomplishment Instructions of B/E Aerospace Service Bulletin 117042-35-001, dated December 10, 2014 (for 15 minute passenger chemical oxygen generators); or Airbus AOT A35W008-14, dated December 18, 2014, including Appendix A, undated (for 22 minute passenger chemical oxygen generators); as applicable.
| 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 (XX represents any numerical value) 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 A35W008-14, dated December 18, 2014, including Appendix A, undated. The report must include the information specified in Appendix A, undated, of Airbus AOT A35W008-14, dated December 18, 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 defined 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.
