Download as PDF 39580 Federal Register / Vol. 73, No. 133 / Thursday, July 10, 2008 / Rules and Regulations Authority for This Rulemaking § 39.13 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. I Regulatory Findings 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 that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Is not a ‘‘significant rule’’ under 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. You can find our regulatory evaluation and the estimated costs of compliance in the AD Docket.

ACTION: Final rule. AGENCY: SUMMARY: We are adopting a new airworthiness directive (AD) for the E:\FR\FM\10JYR1.SGM 10JYR1 Federal Register / Vol. 73, No. 133 / Thursday, July 10, 2008 / Rules and Regulations 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: A300–53–0282 or A300[–53]–0291 or A300– 57–6069 in the affected area. The SB A300– 53–0381, A300–53–0383 and A300–57–6102 define the various configurations for the mandatory [repetitive] inspections to be conducted in order to control or correct the development of cracks [in the center wing box at FR47], which could affect the structural integrity of the aircraft. Due to several crack findings in the area of wing centre box lower aft corner at FR47, this area of structure has been subjected to accomplishment of several inspection Service Bulletins rendered mandatory in accordance with Airworthiness Limitation Items requirement for A300 aircraft and Airworthiness Directive (AD) F–2004–159 for A300–600 aircraft [which corresponds to FAA AD 2005–23–08]. This AD is published * * * in order to control or correct the development of cracks, which could affect the structural integrity of the aircraft. The inspections include x-ray, high frequency eddy current, visual, and ultrasonic inspections. Corrective actions include contacting Airbus if any cracking is found, repairing if any cracking is found, and doing other specified actions. The other specified actions include contacting Airbus for oversizing fastener holes, oversizing fastener holes, installing new fasteners, and installing new plugs. You may obtain further information by examining the MCAI in the AD docket. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective August 14, 2008. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of August 14, 2008. ADDRESSES: You may examine the AD docket on the Internet at http:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC. FOR FURTHER INFORMATION CONTACT: Dan Rodina, Aerospace Engineer, International Branch, ANM–116, Transport Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington 98057–3356; telephone (425) 227–2125; fax (425) 227–1149. SUPPLEMENTARY INFORMATION: Discussion mstockstill on PROD1PC66 with RULES 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 February 29, 2008 (73 FR 11067). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Due to several crack findings in the area of wing centre box lower aft corner at FR47, this area of structure has been subjected to accomplishment of several inspection Service Bulletins [SBs] rendered mandatory in accordance with Airworthiness Limitation Items requirement for A300 aircraft and Airworthiness Directive (AD) F–2004–159 for A300–600 aircraft [which corresponds to FAA AD 2005–23–08]. This AD is published in order to render mandatory an inspection subsequent to accomplishment of repair SB VerDate Aug<31>2005 16:54 Jul 09, 2008 Jkt 214001 Comments We gave the public the opportunity to participate in developing this AD. We considered the comment received. Request To Revise Cost Air Transport Association (ATA), on behalf of its member, American Airlines, states that the cost estimate of $1,760 specified in the NPRM is far too low. ATA states that Airbus Service Bulletin A300–57–6102, dated January 12, 2007 (which is referred to as an appropriate source of service information for doing certain actions specified in the NPRM), specifies that an accomplishment kit costs $1,650 for one wing and that the labor requirement for inspecting one wing is 19 hours. ATA notes that costs will double for airplanes on which Airbus A300–57– 6102 is accomplished on both wings. We agree that the cost estimate is too low. We have revised the labor hours in the Costs of Compliance section of this AD to reflect the 38 hours necessary to inspect both wings. However, we do not agree to add the cost of the kits necessary to do applicable corrective actions. The information in the Costs of Compliance section is limited to the cost of actions actually required by the AD. It does not consider the costs of ‘‘on-condition’’ actions (e.g., ‘‘repair, as applicable’’) because, regardless of AD direction, those actions would be required to correct an unsafe condition identified in an airplane and ensure operation of that airplane in an airworthy condition, as required by the Federal Aviation Regulations. New Service Information Airbus has issued Service Bulletins A300–53–0381, A300–53–0383, and PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 39581 A300–57–6102, all including Appendix 1, all Revision 01, all dated May 27, 2008 (we referred to the original issues of the service bulletins as the appropriate source of service information for accomplishing the actions specified in the NPRM). Revision 01 of the service bulletins specify that no more action is needed on airplanes on which actions specified in the original issues have been done. Revision 01 of the service bulletins updates the Effectivity section and clarifies the unit of measurement for the values of certain tables in the Compliance section of the service bulletins. We have revised this final rule to refer to Revision 01 of the service bulletins. We have not restated paragraph (f)(1)(ii) of the NPRM in this AD because Revision 01 of the service bulletins addresses the unit of measurement for the specified tables. We have also added paragraph (f)(5) of this AD to give credit for actions done in accordance with the original issues of the service bulletins. Revision to Airplane Model Reference For clarity, we have revised the airplane model references in paragraphs (c)(1), (c)(2), (c)(3) of this AD by adding the word ‘‘airplanes’’ to the model designations as published in the most recent type certificate data sheet for the affected models. Conclusion We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We determined that 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. E:\FR\FM\10JYR1.SGM 10JYR1 39582 Federal Register / Vol. 73, No. 133 / Thursday, July 10, 2008 / Rules and Regulations Costs of Compliance We estimate that this AD will affect 107 products of U.S. registry. We also estimate that it will take about 38 workhours per product to comply with the basic requirements of this AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $325,280, or $3,040 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. mstockstill on PROD1PC66 with RULES 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. Examining the AD Docket You may examine the AD docket on the Internet at http:// 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.

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:

    Due to several crack findings in the area of wing centre box

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 February 29, 2008 
(73 FR 11067). That NPRM proposed to correct an unsafe condition for 
the specified products. The MCAI states:

    Due to several crack findings in the area of wing centre box 
lower aft corner at FR47, this area of structure has been subjected 
to accomplishment of several inspection Service Bulletins [SBs] 
rendered mandatory in accordance with Airworthiness Limitation Items 
requirement for A300 aircraft and Airworthiness Directive (AD) F-
2004-159 for A300-600 aircraft [which corresponds to FAA AD 2005-23-
08]. This AD is published in order to render mandatory an inspection 
subsequent to accomplishment of repair SB A300-53-0282 or A300[-53]-
0291 or A300-57-6069 in the affected area. The SB A300-53-0381, 
A300-53-0383 and A300-57-6102 define the various configurations for 
the mandatory [repetitive] inspections to be conducted in order to 
control or correct the development of cracks [in the center wing box 
at FR47], which could affect the structural integrity of the 
aircraft.

    The inspections include x-ray, high frequency eddy current, visual, 
and ultrasonic inspections. Corrective actions include contacting 
Airbus if any cracking is found, repairing if any cracking is found, 
and doing other specified actions. The other specified actions include 
contacting Airbus for oversizing fastener holes, oversizing fastener 
holes, installing new fasteners, and installing new plugs. You may 
obtain further information by examining the MCAI in the AD docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received.

Request To Revise Cost

    Air Transport Association (ATA), on behalf of its member, American 
Airlines, states that the cost estimate of $1,760 specified in the NPRM 
is far too low. ATA states that Airbus Service Bulletin A300-57-6102, 
dated January 12, 2007 (which is referred to as an appropriate source 
of service information for doing certain actions specified in the 
NPRM), specifies that an accomplishment kit costs $1,650 for one wing 
and that the labor requirement for inspecting one wing is 19 hours. ATA 
notes that costs will double for airplanes on which Airbus A300-57-6102 
is accomplished on both wings.
    We agree that the cost estimate is too low. We have revised the 
labor hours in the Costs of Compliance section of this AD to reflect 
the 38 hours necessary to inspect both wings.
    However, we do not agree to add the cost of the kits necessary to 
do applicable corrective actions. The information in the Costs of 
Compliance section is limited to the cost of actions actually required 
by the AD. It does not consider the costs of ``on-condition'' actions 
(e.g., ``repair, as applicable'') because, regardless of AD direction, 
those actions would be required to correct an unsafe condition 
identified in an airplane and ensure operation of that airplane in an 
airworthy condition, as required by the Federal Aviation Regulations.

New Service Information

    Airbus has issued Service Bulletins A300-53-0381, A300-53-0383, and 
A300-57-6102, all including Appendix 1, all Revision 01, all dated May 
27, 2008 (we referred to the original issues of the service bulletins 
as the appropriate source of service information for accomplishing the 
actions specified in the NPRM). Revision 01 of the service bulletins 
specify that no more action is needed on airplanes on which actions 
specified in the original issues have been done. Revision 01 of the 
service bulletins updates the Effectivity section and clarifies the 
unit of measurement for the values of certain tables in the Compliance 
section of the service bulletins.
    We have revised this final rule to refer to Revision 01 of the 
service bulletins. We have not restated paragraph (f)(1)(ii) of the 
NPRM in this AD because Revision 01 of the service bulletins addresses 
the unit of measurement for the specified tables. We have also added 
paragraph (f)(5) of this AD to give credit for actions done in 
accordance with the original issues of the service bulletins.

Revision to Airplane Model Reference

    For clarity, we have revised the airplane model references in 
paragraphs (c)(1), (c)(2), (c)(3) of this AD by adding the word 
``airplanes'' to the model designations as published in the most recent 
type certificate data sheet for the affected models.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting the 
AD with the changes described previously. We determined that 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.

[[Page 39582]]

Costs of Compliance

    We estimate that this AD will affect 107 products of U.S. registry. 
We also estimate that it will take about 38 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $80 per work-hour. Based on these figures, we estimate the cost of 
this AD to the U.S. operators to be $325,280, or $3,040 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.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://
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. The AD docket contains the NPRM, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.
