2009-25-12 Airbus: Amendment 39-16132. Docket No. FAA-2009-1112; Directorate Identifier 2009-NM-237-AD. Effective Date (a) This airworthiness directive (AD) becomes effective December 28, 2009. Affected ADs (b) None. Applicability (c) This AD applies to the airplanes identified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD, all serial numbers, certificated in any category, if delivered before October 26, 2009. (1) Airbus Model A330-201, -202, -203, -223, -243, -301, -302, - 303, -321, -322, -323, -341, -342, and -343 series airplanes, on which Airbus modification 48809 has been embodied in production. (2) Airbus Model A340-211, -212, -213, -311, -312, and -313 series airplanes, on which Airbus modification 48809 has been embodied in production. (3) Airbus Model A340-541 and -642 airplanes. Subject (d) Air Transport Association (ATA) of America Code 35: Oxygen. Reason (e) The mandatory continued airworthiness information (MCAI) states: In-Service experience has shown cases where several oxygen containers could not fully open. Investigations have revealed that these events are due to an insufficient clearance between the oxygen container and the adjacent panels (Passenger Service Unit (PSU), spacers or filler panels). Incorrect opening of the oxygen containers could lead to nondeployment of oxygen masks. This condition, if not detected and corrected, could prevent passengers from being supplied with oxygen in case of in-flight cabin depressurization, which would constitute an unsafe condition. To prevent such condition, this AD requires a one-time [general visual] inspection of the oxygen containers and adjacent panels installation and corrective actions, as necessary, to ensure an adequate clearance between these components. Corrective actions include adjusting oxygen containers and tightening locking devices. Compliance (f) You are responsible for having the actions required bythis AD performed within the compliance times specified, unless the actions have already been done. Actions (g) Unless already done, do the following actions: (1) Within 150 flight hours after the effective date of this AD: Do a general visual inspection of the clearance between the oxygen container door lid and the adjacent panel/component of each cabin oxygen container located in the passenger service channel, in accordance with paragraph 4.2 of the applicable all operators telex (AOT) identified in Table 1 of this AD.

A340 500 and 600 series airplanes A340 35A5019 October 26, 2009. (2) If any clearance is determined to be less than 2.0 millimeters during any inspection required by paragraph (g)(1) of this AD: Before further flight, do all corrective actions in accordance with paragraph 4.2 of the applicable AOT identified in Table 1 of this AD. FAA AD Differences Note 1: This AD differs from the MCAI and/or service information as follows: No differences. Other FAA AD Provisions (h) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Before using any approved AMOC on any airplane to which the AMOC applies, notify your principal maintenance inspector (PMI) or principal avionics inspector (PAI), as appropriate, or lacking a principal inspector, your local Flight Standards District Office. The AMOC approval letter must specifically reference this AD. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
