Airworthiness Directive · Amendment 39-21474 · Oxygen
Airbus SAS Airplanes
Superseded. A later AD replaced this one: AD 2022-21-01. Comply with the one in force.
This AD applies to the Airbus SAS airplanes specified in paragraphs (c)(1) and (2) of this AD, certificated in any category, converted to freighter airplanes in accordance with FAA supplemental type certificate (STC) ST04038NY and STC ST04045NY.
(1) Model A330-201, -202, -203, -223, and -243 airplanes.
(2) Model A330-301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-200 series and A330-300 series airplanes. This AD was prompted by reports of cracked flexible hoses in the courier area oxygen system (CAOS). This AD requires repetitive detailed inspections of the CAOS and replacement of affected parts if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
The definitions in paragraphs (g)(1) and (2) 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.
Within 1,600 flight hours after the effective date of this AD 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; or Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0002, dated September 2, 2019; as applicable.
If, during any inspection required by paragraph (h) of this AD, any leakage or damage (i.e., cracking) is found, replace the affected part before further flight, in accordance with the Accomplishment Instructions of Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0001, dated March 8, 2019; or Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0002, dated September 2, 2019; as applicable.
As of the effective date of this AD, installation of an affected part, as defined in paragraph (g)(1) of this AD, on any airplane is allowed, provided it is a serviceable part, as defined in paragraph (g)(2) of this AD.
Although Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0001, dated March 8, 2019; and Elbe Flugzeugwerke GmbH Service Bulletin EFW-SB-35-0002, dated September 2, 2019; specify to submit certain information to the manufacturer, this AD does not include that requirement.
