14 CFR Part 39

[Docket No. FAA-2011-0474; Directorate Identifier 2010-NM-213-AD]
RIN 2120-AA64

Airworthiness Directives; Airbus Model A330-200 and -300 Series 
Airplanes, and Model A340-200 and -300 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed 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:

    It was noticed in production that the distance between the wire 
harnesses 5376VB/2M and 5377VB/1M which are above the left-hand (LH) 
and right-hand (RH) door 4, and the air conditioning duct could be 
too small. This could result in collision between the flexible air 
conditioning hose and wire harnesses.
    This condition, if not corrected, could lead to the short 
circuit of wires dedicated to oxygen, which, in case of emergency, 
could result in a large number of passenger oxygen masks not being 
supplied with oxygen, possibly causing personal injuries.
* * * * *
The proposed AD would require actions that are intended to address the 
unsafe condition described in the MCAI.

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 2010-0103R1, dated April 28, 2011 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    It was noticed in production that the distance between the wire 
harnesses 5376VB/2M and 5377VB/1M which are above the left-hand (LH) 
and right-hand (RH) door 4, and the air conditioning duct could be 
too small. This could result in collision between the flexible air 
conditioning hose and wire harnesses.
    This condition, if not corrected, could lead to the short 
circuit of wires dedicated to oxygen, which, in case of emergency, 
could result in a large number of passenger oxygen masks not being 
supplied with oxygen, possibly causing personal injuries.
    For the reasons described above, this [EASA] AD requires the 
installation of a protective sleeve and an additional bracket to 
maintain the appropriate distance between wires.
    Revision 1 of this [EASA] AD is issued to revise the 
applicability section of this AD in order to take into account all 
configurations of air conditioning duct and the associated solutions 
embodied in production.

For certain airplanes, required actions include modifying the support 
assembly of the air outlet. For other airplanes, required actions 
include exchanging certain attachment screws of the air outlet box 
assembly on each door. You may obtain further information by examining 
the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletins A330-92-3077, 
Revision 01, dated March 29, 2010 (for Model A330-200 and -300 series 
airplanes); and A340-92-4078, Revision 01, dated April

[[Page 29674]]

9, 2010 (for Model A340-200 and -300 series airplanes).

FAA's Determination and Requirements of This Proposed 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 proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Differences Between This 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 proposed 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 proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 41 products of U.S. registry. We also estimate that 
it would take up to 11 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Required parts would cost up to $503 per product. Where the 
service information lists required parts costs that are covered under 
warranty, we have assumed that there will be no charge for these costs. 
As we do not control warranty coverage for affected parties, some 
parties may incur costs higher than estimated here. Based on these 
figures, we estimate the cost of the proposed AD on U.S. operators to 
be up to $58,958, or up to $1,438 per product.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    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 proposed AD and placed it in the AD docket.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Airbus: Docket No. FAA-2011-0474; Directorate Identifier 2010-NM-
213-AD.

Comments Due Date

    (a) We must receive comments by July 7, 2011.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to the Airbus airplanes identified in 
paragraphs (c)(1) and (c)(2) of this AD, all manufacturer serial 
numbers; certificated in any category; except those identified in 
paragraph (c)(3) of this AD.
    (1) Model A330-201, -202, -203, -223, -243, -301, -302, -303, -
321, -322, -323, -341, -342, and -343 airplanes.
    (2) Model A340-211, -212, -213, -311, -312, and -313 airplanes.
    (3) Airplanes on which the following Airbus Modifications are

or Airbus Modification 201642 or 57562.

Subject

    (d) Air Transport Association (ATA) of America Code 92.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    It was noticed in production that the distance between the wire 
harnesses 5376VB/2M and 5377VB/1M which are above the left-hand (LH) 
and right-hand (RH) door 4, and the air conditioning duct could be 
too small. This could result in collision between the flexible air 
conditioning hose and wire harnesses.
    This condition, if not corrected, could lead to the short 
circuit of wires dedicated to oxygen, which, in case of emergency, 
could result in a large number of passenger oxygen masks not being 
supplied with oxygen, possibly causing personal injuries.
