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: A specific area, the lower tail plane cut-out located in the tail cone is subject to an inspection programme [for cracking] * * *. * * * * * The unsafe condition is reduced structural integrity of the tail cone. We PO 00000 Frm 00028 Fmt 4700 Sfmt 4700 are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective June 15, 2011. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of June 15, 2011. ADDRESSES: You may examine the AD docket on the Internet at https:// 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 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 January 3, 2011 (76 FR 46). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: A specific area, the lower tail plane cut-out located in the tail cone is subject to an inspection programme specified in the Airbus Service Bulletin (SB) A310–53–2074. EASA issued AD 2007–0053 [which superseded French AD 1992–106–132 R6; French AD 1992–106–132 corresponds to FAA AD 98–26–01] to require the accomplishment of this SB at Revision 03. Airbus has established that this SB needed to be revised in order to state correct threshold and intervals due to errors introduced at revision 03. Consequently, revision 04 of this SB has been issued, and opportunity was taken: —To clarify the inspection area and associated threshold and intervals —To take aeroplane utilisation into consideration, in accordance with the A310 life extension programme. For the reasons stated above, this EASA AD takes over the requirements of paragraph 1.16 of EASA AD 2007–0053R1 [currently at R3], which has been revised accordingly, and requires accomplishment of the instructions contained in Airbus SB A310–53–2074 at Revision 04. The unsafe condition is reduced structural integrity of the tail cone. The required actions include repetitive and one-time inspections, depending on the area, of the lower tail plane cut-out, and corrective actions if necessary. The inspections include the following: E:\FR\FM\11MYR1.SGM 11MYR1 Federal Register / Vol. 76, No. 91 / Wednesday, May 11, 2011 / Rules and Regulations • Detailed inspections in areas 1, 2, and 3 for cracking and corrosion of the lower horizontal stabilizer cutout longeron, the corner fitting, the skin strap, and the skin. • Detailed inspections in areas 1, 2, and 3 for damaged sealant. • Eddy current inspections in area 1 for cracking. • Eddy current inspections in area 2 for cracking. • Rotating probe inspection for cracking of specified fastener holes in Area 3. The corrective actions, depending on the conditions found, include the following: • Repairing corrosion. • Contacting Airbus for repair instructions. • Replacing damaged sealant. • Removing cracking. • Doing an eddy current inspection for cracking of the reworked area. • Installing a new corner fitting. • Doing a rotating probe inspection for cracking of fastener holes. • Doing an eddy current inspection of the longeron and outer skin. • Drilling or reaming fastener holes. 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 received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. srobinson on DSKHWCL6B1PROD with RULES 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 44 products of U.S. registry. We also VerDate Mar<15>2010 16:21 May 10, 2011 Jkt 223001 estimate that it will take about 36 workhours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $134,640, or $3,060 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 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 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. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information.

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:

    A specific area, the lower tail plane cut-out located in the 
tail cone is subject to an inspection programme [for cracking] * * 
*.
* * * * *
    The unsafe condition is reduced structural integrity of the tail 
cone. We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective June 15, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of June 15, 
2011.

ADDRESSES: You may examine the AD docket on the Internet at https://www.regulations.gov or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor,

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 January 3, 2011 (76 
FR 46). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    A specific area, the lower tail plane cut-out located in the 
tail cone is subject to an inspection programme specified in the 
Airbus Service Bulletin (SB) A310-53-2074. EASA issued AD 2007-0053 
[which superseded French AD 1992-106-132 R6; French AD 1992-106-132 
corresponds to FAA AD 98-26-01] to require the accomplishment of 
this SB at Revision 03.
    Airbus has established that this SB needed to be revised in 
order to state correct threshold and intervals due to errors 
introduced at revision 03. Consequently, revision 04 of this SB has 
been issued, and opportunity was taken:

--To clarify the inspection area and associated threshold and 
intervals
--To take aeroplane utilisation into consideration, in accordance 
with the A310 life extension programme.

    For the reasons stated above, this EASA AD takes over the 
requirements of paragraph 1.16 of EASA AD 2007-0053R1 [currently at 
R3], which has been revised accordingly, and requires accomplishment 
of the instructions contained in Airbus SB A310-53-2074 at Revision 
04.

The unsafe condition is reduced structural integrity of the tail cone. 
The required actions include repetitive and one-time inspections, 
depending on the area, of the lower tail plane cut-out, and corrective 
actions if necessary. The inspections include the following:

[[Page 27247]]

     Detailed inspections in areas 1, 2, and 3 for cracking and 
corrosion of the lower horizontal stabilizer cutout longeron, the 
corner fitting, the skin strap, and the skin.
     Detailed inspections in areas 1, 2, and 3 for damaged 
sealant.
     Eddy current inspections in area 1 for cracking.
     Eddy current inspections in area 2 for cracking.
     Rotating probe inspection for cracking of specified 
fastener holes in Area 3.
    The corrective actions, depending on the conditions found, include 
the following:
     Repairing corrosion.
     Contacting Airbus for repair instructions.
     Replacing damaged sealant.
     Removing cracking.
     Doing an eddy current inspection for cracking of the 
reworked area.
     Installing a new corner fitting.
     Doing a rotating probe inspection for cracking of fastener 
holes.
     Doing an eddy current inspection of the longeron and outer 
skin.
     Drilling or reaming fastener holes.
    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 received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed.

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 44 products of U.S. registry. 
We also estimate that it will take about 36 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Based on these figures, we estimate the cost of 
this AD to the U.S. operators to be $134,640, or $3,060 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

    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 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. 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.
