AD 2009-25-12

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

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 non deployment 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 * * *.

This AD requires actions that are intended to address the unsafe condition described in the MCAI.

Final rule; request for comments.

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.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2009-0237-E, dated October 30, 2009 (referred to after this as "the MCAI''), to correct an unsafe condition for the specified products. The 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 non deployment 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. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Airbus has issued All Operators Telexes A330-35A3026, A340-35A4027, and A340-35A5019, all dated October 26, 2009. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we 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.

Differences Between the AD and the MCAI or Service Information

We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information.
We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a Note within the AD.

FAA's Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because the compliance time defined in the MCAI is 150 flight hours for accomplishing the initial inspection for insufficient clearance between the oxygen container and the adjacent panels. Incorrect opening of the oxygen containers could lead to non-deployment of the oxygen masks, which could prevent passengers from being supplied with oxygen in case of in-flight cabin depressurization. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include "Docket No. FAA-2009-1112; Directorate Identifier 2009-NM-237-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.
We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.

Authority for This Rulemaking

Title 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.
We are issuing this rulemaking under the authority described in "Subtitle 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.

Regulatory Findings

We 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.
For the reasons discussed above, I certify this AD:
1. Is not a "significant regulatory action'' under Executive Order 12866;
2. Is not a "significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034,February 26, 1979); and
3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket.
