Airworthiness Directive · Amendment 39-22200 · Oxygen
Airbus SAS Airplanes
This AD applies to Airbus SAS Model A330-243, -322, and -343 airplanes, certificated in any category, converted to freighter airplanes in accordance with FAA supplemental type certificate (STC) ST04038NY and STC ST04045NY, having manufacturer serial numbers 0116, 0127, 0231, 0600, 0610, 0709, 0777, and 0781.
The FAA is superseding Airworthiness Directive (AD) 2021-06- 07, which applied to certain Airbus SAS Model A330-200 series and A330- 300 series airplanes. AD 2021-06-07 required repetitive detailed inspections of the courier area oxygen system (CAOS) and replacement of affected parts if necessary. Since the FAA issued AD 2021-06-07, improved flexible oxygen hoses have been developed. This AD continues to require repetitive detailed inspections of the CAOS and replacement of affected parts if necessary. This AD also requires replacing each affected part with an improved serviceable part, which is terminating action for the repetitive inspections. The FAA is issuing this AD to address the unsafe condition on these products.
The definitions in paragraphs (g)(1) through (3) of this AD apply.
(1) An affected part is a 32209-series oxygen flexible hose used in the CAOS, having a part number specified in figure 1 to paragraph (g)(1) of this AD.
(2) A serviceable part is an affected part that is new (never previously installed), or that, before further flight after installation into the CAOS, has passed an inspection and functional test (no leakage or damage found) as specified in paragraph (h) of this AD.
(3) An improved serviceable part is a flexible hose having a part number as specified in figure 1 to paragraph (g)(1) of this AD.
This paragraph restates the requirements of paragraph (h) of AD 2021-06-07, with revised service information. Within 1,600 flight hours after April 20, 2021 (the effective date of AD 2021-06-07) and thereafter at intervals not to exceed 1,600 flight hours, do a detailed inspection (including functional testing) for leakage or damage of the CAOS and lavatory A oxygen system in accordance with the Accomplishment Instructions of Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0001, dated March 8, 2019; Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0002, dated September 2, 2019; Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0001, Revision 01, dated July 3, 2020; or Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0002, Revision 01, dated June 22, 2020; as applicable.
This paragraph restates the requirements of paragraph (i) of AD 2021-06-07, with revised service information and a new replacement action option. If, during any inspection required by paragraph (h) of this AD, any leakage or damage (i.e., cracking) is found: Before further flight, do the actions specified in paragraph (i)(1) or (2) of this AD:
(1) Replace the affected part with a serviceable part, as defined in paragraph (g)(2) of this AD, in accordance with the Accomplishment Instructions of Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0001, dated March 8, 2019; Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0002, dated September 2, 2019; Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0001, Revision 01, dated July 3, 2020; or Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0002, Revision 01, dated June 22, 2020; as applicable.
(2) Replace each affected part with an improved serviceable part, as defined in paragraph (g)(3) of this AD, in accordance with the Accomplishment Instructions of Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0003, dated January 27, 2021; or Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0006, dated June 9, 2021; as applicable.
Unless already accomplished as specified in paragraph (i) of this AD, within 42 months after the effective date of this AD, modify the airplane by replacing each affected part with an improved serviceable part, as defined in paragraph (g)(3) of this AD, in accordance with the Accomplishment Instructions of Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0003, dated January 27, 2021; or Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0006, dated June 9, 2021; as applicable.
(1) Replacement of an affected part with a serviceable part, as specified in paragraph (i) of this AD, does not terminate the repetitive inspections required by paragraph (h) of this AD.
(2) Modification of an airplane by installing improved serviceable parts as required by paragraph (j) of this AD, or as specified in paragraph (i) of this AD, as applicable, terminates the repetitive inspections required by paragraph (h) of this AD for that airplane.
