Airworthiness Directives; Airbus Model A330-200 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:
* * * * *
European Aviation Safety Agency (EASA)
AD 2006-0191 [which corresponds to FAA AD 2006-21-08] required the installation of new heat shield panels with drainage over the air conditioning packs in order to avoid an undetected fire in this zone following a fuel leak from the centre tank.
These new heat shield panels have holes. In case of fuel leaking through these holes from the centre tank, any fuel vapour may develop into a potential source of ignition, possibly resulting in a fuel tank explosion and consequent loss of the aeroplane.* * *
* * * * *
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 2009-0150, dated July 9, 2009 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states:
* * * EASA AD 2006-0191 [which corresponds to FAA AD 2006-21-08] required the installation of new heat shield panels with drainage over the air conditioning packs in order to avoid an undetected fire in this zone following a fuel leak from the centre tank.
These new heat shield panels have holes. In case of fuel leaking through these holes from the centre tank, any fuel vapour may develop into a potential source of ignition, possibly resulting in a fuel tank explosion and consequent loss of the aeroplane. Airbus has developed a repair solution for these holes to prevent a fuel vapour ignition source in this area and improve the protection of the hot air equipment.
Page 62714
T his AD requires the installation of plugs on the heat shield panels of the Left Hand (LH) and Right Hand (RH) Air Conditioning packs.
You may obtain further information by examining the MCAI in the AD docket.
Relevant Service Information
Airbus has issued Mandatory Service Bulletin A330-21-3148, including Appendix 1, dated January 30, 2009; and Mandatory Service
Bulletin A340-21-4147, including Appendix 1, dated January 30, 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 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 12 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. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $2,880, or $240 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.

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-2009-1107; Directorate Identifier 2009-NM- 138-AD.
Comments Due Date
(a) We must receive comments by January 15, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to the airplanes identified in paragraphs
(c)(1) and (c)(2) of this AD, certificated in any category; on which
Airbus Modification 49520 has been embodied in production, or on which Airbus Service Bulletin A330-21-3096, Revision 01, or Airbus
Service Bulletin A340-21-4107, Revision 01, has been embodied in service; except those airplanes on which Airbus Modification 58551 has been embodied in production.
(1) Airbus Model A330-201, -202, -203, -223, and -243 airplanes, all manufacturer serial numbers.

Subject
(d) Air Transport Association (ATA) of America Code 21: Air conditioning.
Reason
(e) The mandatory continuing airworthiness information (MCAI) states:
EASA [European Aviation Safety Agency] AD 2006-0191 [which corresponds to FAA AD 2006-21-08] required the installation of new heat shield panels with drainage over the air conditioning packs in order to avoid an undetected fire in this zone following a fuel leak from the centre tank.
These new heat shield panels have holes. In case of fuel leaking through these holes from the centre tank, any fuel vapour may develop into a potential source of ignition, possibly resulting in a fuel tank explosion and consequent loss of the aeroplane. Airbus has developed a repair solution for these holes to prevent a fuel vapour ignition source in this area and improve the protection of the hot air equipment.
T his AD requires the installation of plugs on the heat shield panels of the Left Hand (LH) and Right Hand (RH) Air Conditioning packs.
Actions and Compliance
(f) Unless already done, within 24 months after the effective date of this AD: Plug the six receptacle holes on the heat shield of the left-hand air conditioning pack and plug the four receptacle holes on the heat shield of the right-hand air conditioning pack, in accordance with the Accomplishment Instructions of Airbus Mandatory
Service Bulletin A330-21-3148, dated January 30, 2009 (for Model
A330-201, -202, -203, -223, and -243 series airplanes); or Airbus
