Airworthiness Directives; Airbus Model A330-200, A330-300, and 
A340-300 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 in the area between frame (FR) 
C53.9 and FR C55 RH [right-hand], the distance between the route 9R 
of the In-Flight Entertainment system and the wire harness for the 
Lower Deck-Mobile Crew Rest system provisions is too small.
    This limited distance may cause chafing between the affected 
electrical harness 6581VB and the harness 5495VB or 6938VB.
    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 2009-0076, dated April 6, 2009 (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 in the area between frame (FR) 
C53.9 and FR C55 RH [right-hand], the distance between the route 9R 
of the In-Flight Entertainment system and the wire harness for the 
Lower Deck-Mobile Crew Rest system provisions is too small.
    This limited distance may cause chafing between the affected 
electrical harness 6581VB and the harness 5495VB or 6938VB.
    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 AD requires the 
installation of a stirrup on the terminal block 5507VT between 
FR53.9 and FR54, and the re-routing of the wiring route 9R.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletin A330-92-3080, dated 
November 12, 2008; and Mandatory Service Bulletin A340-92-4080, dated 
November 12, 2008. 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 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

[[Page 62712]]

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 43 products of U.S. registry. We also estimate that 
it would take about 3 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. Required parts would cost about $66 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 $13,158, or $306 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.

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 in the area between frame (FR) 
C53.9 and FR C55 RH [right-hand], the distance between the route 9R 
of the In-Flight Entertainment system and the wire harness for the 
Lower Deck-Mobile Crew Rest system provisions is too small.
    This limited distance may cause chafing between the affected 
electrical harness 6581VB and the harness 5495VB or 6938VB.
    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 AD requires the 
installation of a stirrup on the terminal block 5507VT between 
FR53.9 and FR54, and the re-routing of the wiring route 9R.

Actions and Compliance

    (f) Within 24 months after the effective date of this AD, unless 
already done: Install a stirrup on the terminal block 5507VT between 
FR53.9 and FR54 and modify the wiring route 9R in accordance with 
the Accomplishment Instructions of Airbus Mandatory Service Bulletin 
A330-92-3080, dated November 12, 2008; or Airbus Mandatory Service 
Bulletin A340-92-4080, dated November 12, 2008; as applicable.
