AD 2021-06-07 SUPERSEDED

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.

Final rule; request for comments.

Adoption of the Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n\n\nSec. 39.13 (Amended) \n\n0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive: \n\n2021-06-07 Airbus SAS: Amendment 39-21474; Docket No. FAA-2021-0182; Product Identifier 2020-NM-072-AD. \n\n(a) Effective Date \n\n\n\tThis airworthiness directive (AD) becomes effective April 20, 2021. \n\n(b) Affected ADs \n\n\n\tNone. \n\n(c) Applicability \n\n\n\tThis 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. \n\t(1) Model A330-201, -202, -203, -223, and -243 airplanes. \n\t(2) Model A330-301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes. \n\n(d) Subject \n\n\n\tAir Transport Association (ATA) of America Code 35, Oxygen. \n\n(e) Reason \n\n\n\tThis AD was prompted by reports of cracked flexible hoses in the courier area oxygen system (CAOS). The FAA is issuing this AD to address cracked CAOS hoses. This condition, if not addressed, could lead to oxygen leakage in the flexible hoses of the CAOS, which, in combination with in-flight depressurization or smoke evacuation procedure, could result in injury to occupants of the courier area. \n\n(f) Compliance \n\n\n\tComply with this AD within the compliance times specified, unless already done. \n\n(g) Definitions \n\n\n\tThe definitions in paragraphs (g)(1) and (2) of this AD apply. \n\t(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. (GRAPHIC) (TIFF OMITTED) TR05AP21.000 \n\n\n\t(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. \n\n(h) Required Actions \n\n\n\tWithin 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. \n\n(i) Corrective Actions \n\n\n\tIf, 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. \n\n(j) Parts Installation Limitation \n\n\n\tAs 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. \n\n(k) No Reporting Requirement \n\n\n\tAlthough 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. \n\n(l) Other FAA AD Provisions \n\n\n\tThe following provisions also apply to this AD: \n\t(1) Alternative Methods of Compliance (AMOCs): The Manager, New York ACO Branch, FAA, has the authority to approve AMOCs for this AD, ifrequested using the procedures found in 14 CFR 39.19.

Discussion \n\n\n\tThe European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0215, dated September 4, 2019 (referred to after this as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for certain Airbus SAS Model A330-201, A330-202, A330-203, A330-223, A330-243, A330-301, A330-302, A330-303, A330-321, A330-322, A330-323, A330-341, A330-342 and A330-343 airplanes. You may examine the MCAI on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2021- 0182. \n\tThis AD was prompted by reports of cracked flexible hoses in the CAOS. The FAA is issuing this AD to address cracked CAOS hoses. This condition, if not addressed, could lead to oxygen leakage in the flexible hoses of the CAOS, which, in combination with in-flight depressurization or smoke evacuation procedure, could result in injuryto occupants of the courier area. See the MCAI for additional background information. \n\n((Page 17513)) \n\nRelated Service Information Under 1 CFR Part 51 \n\n\n\tElbe Flugzeugwerke GmbH (EFW) has issued Service Bulletin EFW-SB- 35-0001, dated March 8, 2019; and Service Bulletin EFW-SB-35-0002, dated September 2, 2019. This service information describes procedures for repetitive detailed inspections (including functional tests) of the CAOS to detect any leakage or damage (cracking) in the 32209-series oxygen distribution hoses installed in the courier area and in lavatory A, and replacement. \n\tThis service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. \n\nFAA's Determination \n\n\n\tThis product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to the FAA's bilateral agreement withthe State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI and service information referenced above. The FAA is issuing this AD because the FAA evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. \n\nRequirements of This AD \n\n\n\tThis AD requires accomplishing the actions specified in the service information described previously. \n\nFAA's Justification and Determination of the Effective Date \n\n\n\tThere are currently no domestic operators of these products. Therefore, the FAA finds that notice and opportunity for prior public comment are unnecessary and that good cause exists for making this amendment effective in less than 30 days. \n\nComments Invited \n\n\n\tThe FAA invites you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under ADDRESSES. Include ''Docket No. FAA-2021-0182; Product Identifier 2020- NM-072-AD'' at the beginning of your comments. The most helpful comments reference a specific portion of the final rule, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend this final rule because of those comments. \n\tExcept for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to https://www.regulations.gov, including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this final rule. \n\nConfidential Business Information \n\n\n\tCBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this AD contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this AD, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as ''PROPIN.'' The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this AD. Submissions containing CBI should be sent to Darren Gassetto, Aerospace Engineer, Mechanical Systems and Administrative Services Section, FAA, New York ACO Branch, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; telephone 516-228-7323; fax 516-794-5531; email 9-avs-nyaco-cos@faa.gov. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. \n\nRegulatory Flexibility Act (RFA) \n\n\n\tThe requirements of the RFA do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required. \n\nCosts of Compliance \n\n\n\tCurrently, there are no affected U.S.-registered airplanes. If an affected airplane is imported and placed on the U.S. Register in the future, the FAA provides the following cost estimates to comply with this AD: \n\n\n\tEstimated Costs for Required Actions ------------------------------------------------------------------------ \n\tCost per \n\tLabor cost Parts cost product ------------------------------------------------------------------------ 20 work-hours x $85 per hour = $1,700. $0 $1,700 ------------------------------------------------------------------------ \n\n\n\tThe FAA estimates the following costs to do any necessary on- condition actions that would be required basedon the results of any required actions. The FAA has no way of determining the number of aircraft that might need these on-condition actions: \n\n\n\tEstimated Costs of On-Condition Actions ------------------------------------------------------------------------ \n\tCost per \n\tLabor cost Parts cost product ------------------------------------------------------------------------ 7 work-hours x $85 per hour = $595.... $13,485 $14,080 ------------------------------------------------------------------------ \n\nAuthority for This Rulemaking \n\n\n\tTitle 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency's authority. \n\tThe FAA is issuing this rulemaking under the authority described in \n\n((Page 17514)) \n\nSubtitle VII, Part A, Subpart III, Section 44701: General requirements. Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. \n\nRegulatory Findings \n\n\n\tThe FAA determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. \n\tFor the reasons discussed above, I certify that this AD: \n\t(1) Is not a ''significant regulatory action'' under Executive Order 12866, and \n\t(2) Will not affect intrastate aviation in Alaska. \n\nList of Subjects in 14 CFR Part 39 \n\n\n\tAir transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
