DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2007–0347; Directorate Identifier 2007–NM–253–AD; Amendment 39–15437; AD 2008–06–25] RIN 2120–AA64 Airworthiness Directives; Airbus Model A330 and A340 Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: 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: SUMMARY: rfrederick on PROD1PC67 with RULES Two A330 operators have reported that the guide shaft of the Refuel Isolation Valve has been broken away from the main casting and entered the fuel tank. The Supplier Investigation evidenced that water builds-up in the cavity of the Refuel Isolation Valve and freezes during flight. When refuel pressure is applied to the piston, the ice restricts the piston travel on one side leading to an asymmetric movement of the piston resulting in breakage of the guide shaft. A non-bonded metallic object within the fuel tank can result [in] a potential ignition source, which in combination with a lightning strike constitutes an unsafe condition. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective April 23, 2008. The Director of the Federal Register approved the incorporation by reference VerDate Aug<31>2005 15:13 Mar 18, 2008 Jkt 214001 of certain publications listed in this AD as of April 23, 2008.

SUPPLEMENTARY INFORMATION: 4120, both Revision 01, both dated January 11, 2008. We referred to the original issues, both dated July 17, 2007, as the appropriate sources of service information for accomplishing certain actions specified in the NPRM. We find that no additional work is required by these revisions. Therefore, we have changed paragraph (f) of this AD to refer to Revision 01 of Airbus Service Bulletins A330–28–3103 and A340–28– 4120. We have also changed paragraph (f) to give credit to operators who have accomplished the actions in accordance with Airbus Service Bulletins A330–28– 3103 and A340–28–4120, both dated July 17, 2007. Discussion This section of the FEDERAL REGISTER contains regulatory documents having general applicability and legal effect, most of which are keyed to and codified in the Code of Federal Regulations, which is published under 50 titles pursuant to 44 U.S.C. 1510. We have determined that air safety and the public interest require adopting the AD with the changes described previously. These changes will not increase the economic burden on any operator or increase the scope of the AD. We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on December 19, 2007 (72 FR 71828). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Two A330 operators have reported that the guide shaft of the Refuel Isolation Valve has been broken away from the main casting and entered the fuel tank. The Supplier Investigation evidenced that water builds-up in the cavity of the Refuel Isolation Valve and freezes during flight. When refuel pressure is applied to the piston, the ice restricts the piston travel on one side leading to an asymmetric movement of the piston resulting in breakage of the guide shaft. A non-bonded metallic object within the fuel tank can result [in] a potential ignition source, which in combination with a lightning strike constitutes an unsafe condition. For the reasons described above, this Airworthiness Directive (AD) requires replacement of the affected Refuel Isolation Valve with a more robust valve similar to that designed for the A380. You may obtain further information by examining the MCAI in the AD docket. Comments Interested persons have been afforded an opportunity to participate in the making of this amendment. No comments were submitted in response to the proposal or the FAA’s determination of the cost to the public. Revised Service Information We have reviewed Airbus Service Bulletins A330–28–3103 and A340–28– PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 Conclusion 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 required different actions in this AD from those in the MCAI in order to follow our FAA policies. Any such differences are highlighted in a NOTE within the AD. Costs of Compliance We estimate that this AD will affect about 34 products of U.S. registry. We also estimate that it will take about 14 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $80 per work-hour. Required parts will cost about $8,000 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 E:\FR\FM\19MRR1.SGM 19MRR1 14660 Federal Register / Vol. 73, No. 54 / Wednesday, March 19, 2008 / Rules and Regulations AD on U.S. operators to be $310,080, or $9,120 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 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. rfrederick on PROD1PC67 with RULES Examining the AD Docket You may examine the AD docket on the Internet at https:// www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

A similar regulation has been recommended by the JAA (Joint Aviation Authorities) to the European National Aviation Authorities in JAA letter 04/00/02/ 07/03–L024 of 3 February 2003. The review was requested to be mandated by NAA’s (National Aviation Authorities) using JAR (Joint Aviation Regulation) § 25.901(c), § 25.1309. In August 2005 EASA published a policy statement on the process for developing instructions for maintenance and inspection of Fuel Tank System ignition source prevention (EASA D 2005/CPRO, https:// www.easa.eu.int/home/ cert_policy_statements_en.html) that also included the EASA expectations with regard to compliance times of the corrective actions on the unsafe and the not unsafe part of the harmonised design review results. On a global scale the TC (type certificate) holders committed themselves to the EASA published compliance dates (see EASA policy statement). The EASA policy statement has been revised in March 2006: the date of 31–12–2005 for the unsafe related actions has now been set at 01–07–2006. Fuel Airworthiness Limitations are items arising from a systems safety analysis that have been shown to have failure mode(s) associated with an ‘unsafe condition’ as defined in FAA’s memo 2003–112–15 ‘SFAR 88—Mandatory Action Decision Criteria’. These are identified in Failure Conditions for which an unacceptable probability of ignition risk could exist if specific tasks and/or practices are not performed in accordance with the manufacturers’ requirements. This EASA Airworthiness Directive mandates the Fuel System Airworthiness Limitations, comprising maintenance/ inspection tasks and Critical Design Configuration Control Limitations (CDCCL) for the type of aircraft, that resulted from the design reviews and the JAA recommendation and EASA policy statement mentioned above. The corrective action includes revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness for certain airplanes, and E:\FR\FM\19MRR1.SGM 19MRR1

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2007-0347; Directorate Identifier 2007-NM-253-AD; 
Amendment 39-15437; AD 2008-06-25]
RIN 2120-AA64


Airworthiness Directives; Airbus Model A330 and A340 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: 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:

    Two A330 operators have reported that the guide shaft of the 
Refuel Isolation Valve has been broken away from the main casting 
and entered the fuel tank. The Supplier Investigation evidenced that 
water builds-up in the cavity of the Refuel Isolation Valve and 
freezes during flight. When refuel pressure is applied to the 
piston, the ice restricts the piston travel on one side leading to 
an asymmetric movement of the piston resulting in breakage of the 
guide shaft. A non-bonded metallic object within the fuel tank can 
result [in] a potential ignition source, which in combination with a 
lightning strike constitutes an unsafe condition.

We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective April 23, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of April 23, 
2008.

ADDRESSES: You may examine the AD docket on the Internet at https://

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on December 19, 2007 
(72 FR 71828). That NPRM proposed to correct an unsafe condition for 
the specified products. The MCAI states:

    Two A330 operators have reported that the guide shaft of the 
Refuel Isolation Valve has been broken away from the main casting 
and entered the fuel tank. The Supplier Investigation evidenced that 
water builds-up in the cavity of the Refuel Isolation Valve and 
freezes during flight. When refuel pressure is applied to the 
piston, the ice restricts the piston travel on one side leading to 
an asymmetric movement of the piston resulting in breakage of the 
guide shaft. A non-bonded metallic object within the fuel tank can 
result [in] a potential ignition source, which in combination with a 
lightning strike constitutes an unsafe condition.
    For the reasons described above, this Airworthiness Directive 
(AD) requires replacement of the affected Refuel Isolation Valve 
with a more robust valve similar to that designed for the A380.

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

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were submitted in response 
to the proposal or the FAA's determination of the cost to the public.

Revised Service Information

    We have reviewed Airbus Service Bulletins A330-28-3103 and A340-28-
4120, both Revision 01, both dated January 11, 2008. We referred to the 
original issues, both dated July 17, 2007, as the appropriate sources 
of service information for accomplishing certain actions specified in 
the NPRM. We find that no additional work is required by these 
revisions. Therefore, we have changed paragraph (f) of this AD to refer 
to Revision 01 of Airbus Service Bulletins A330-28-3103 and A340-28-
4120. We have also changed paragraph (f) to give credit to operators 
who have accomplished the actions in accordance with Airbus Service 
Bulletins A330-28-3103 and A340-28-4120, both dated July 17, 2007.

Conclusion

    We have determined that air safety and the public interest require 
adopting the AD with the changes described previously. These changes 
will not increase the economic burden on any operator or increase the 
scope of the AD.

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 required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect about 34 products of U.S. 
registry. We also estimate that it will take about 14 work-hours per 
product to comply with the basic requirements of this AD. The average 
labor rate is $80 per work-hour. Required parts will cost about $8,000 
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

[[Page 14660]]

AD on U.S. operators to be $310,080, or $9,120 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 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.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2008-06-25 Airbus: Amendment 39-15437. Docket No. FAA-2007-0347; 
Directorate Identifier 2007-NM-253-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective April 
23, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to the Airbus Model A330 and A340 airplanes 
identified in paragraphs (c)(1) and (c)(2) of this AD; certificated 
in any category; all certified models; all serial numbers.
    (1) Model A330 and A340 airplanes except those on which Airbus 
Modification 55664 has been embodied in production or Airbus Service 
Bulletin A330-28-3103, A340-28-4120, or A340-28-5044 has been 
embodied in service.
    (2) Model A330-300 series airplanes on which Airbus Modification 
40176 (optional LH (left hand) coupling) has been embodied in 
production or Airbus Service Bulletin A330-28-3018 (optional LH 
coupling) has been embodied in service; except those on which Airbus 
Modification 56148 has been embodied in production or Airbus Service 
Bulletin A330-28-3103 has been embodied in service.

Subject

    (d) Air Transport Association (ATA) of America Code 28: Fuel.

Reason

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

    Two A330 operators have reported that the guide shaft of the 
Refuel Isolation Valve has been broken away from the main casting 
and entered the fuel tank. The Supplier Investigation evidenced that 
water builds-up in the cavity of the Refuel Isolation Valve and 
freezes during flight. When refuel pressure is applied to the 
piston, the ice restricts the piston travel on one side leading to 
an asymmetric movement of the piston resulting in breakage of the 
guide shaft. A non-bonded metallic object within the fuel tank can 
result [in] a potential ignition source, which in combination with a 
lightning strike constitutes an unsafe condition.
    For the reasons described above, this Airworthiness Directive 
(AD) requires replacement of the affected Refuel Isolation Valve 
with a more robust valve similar to that designed for the A380.

Actions and Compliance

    (f) Unless already done, do the following actions in accordance 
with the instructions defined in Airbus Service Bulletins A330-28-
3103 and A340-28-4120, both Revision 01, both dated January 11, 
2008; and A340-28-5044, dated July 17, 2007; as applicable. Actions 
done before the effective date of this AD in accordance with Airbus 
Service Bulletins A330-28-3103 and A340-28-4120, both dated July 17, 
2007, are acceptable for compliance with the corresponding 
requirements of this AD.
    (1) Within 18,000 flight hours from the effective date of this 
AD: Replace the refuel isolation valve(s); and re-identify the 
refuel/defuel coupling in accordance with the instructions defined 
in the applicable service bulletin.
    (2) For refuel Isolation Valve and Refuel/Defuel Coupling Spare 
units: From the effective date of this AD, no person may install an 
affected refuel isolation valve unit or an affected refuel/defuel 
coupling unit as a replacement part on an aircraft, unless it has 
been modified in accordance with the instructions defined in the 
applicable service bulletin.

FAA AD Differences

    Note: This AD differs from the MCAI and/or service information 
as follows: No differences.

Other FAA AD Provisions

    (g) 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. Send information to ATTN: 
Vladimir Ulyanov, Aerospace Engineer, International Branch, ANM-116, 
Transport Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, 
Washington 98057-3356; telephone (425) 227-1138; fax (425) 227-1149. 
Before using any approved AMOC on any airplane to which the AMOC 
applies, notify your appropriate principal inspector (PI) in the FAA 
Flight Standards District Office (FSDO), or lacking a PI, your local 
FSDO.
    (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, the 
Office of Management and Budget (OMB)

[[Page 14661]]

has approved the information collection requirements and has 
assigned OMB Control Number 2120-0056.
