ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain Airbus Model A330–200 freighter series airplanes; Model A330–200 and –300 series airplanes; and Model A340–200 and –300 series airplanes. This AD was prompted by a report of corrosion found on the main fitting of the nose landing gear (NLG) leg in the vicinity of the SUMMARY: PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 dowel pin bushes retaining the lower steering flange. This AD requires modifying the NLG main fitting by adding primer paint to the cadmium around the dowel bush holes. We are issuing this AD to prevent NLG main fitting rupture, which could result in an NLG collapse. DATES: This AD becomes effective June 21, 2012. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of June 21, 2012. 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.

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 29, 2011 (76 FR 81884). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Corrosion has been found on the main fitting of the NLG leg in the vicinity of the dowel pin bushes retaining the lower steering flange on A330/A340 aeroplanes. The majority of parts have been reworked and returned to service. This corrosion, if not avoided, could lead to the NLG main fitting rupture, possibly resulting in a NLG collapse, which would constitute an unsafe condition. In order to maintain the structural integrity of the NLG, this [EASA] AD requires the accomplishment of a modification which consists in adding primer paint to the cadmium around the dowel bush holes on the main fitting, in order to provide further protection against cadmium degradation. 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 (76 FR 81884, December 29, 2011) or on the determination of the cost to the public. E:\FR\FM\17MYR1.SGM 17MYR1 Federal Register / Vol. 77, No. 96 / Thursday, May 17, 2012 / Rules and Regulations Changes to the AD Authority for This Rulemaking Airbus has issued Mandatory Service Bulletins A330–32–3241 and A340–32– 4282, both Revision 01, both including Appendix 01, both dated October 6, 2011, which correct certain aircraft maintenance manual references. We referred to Airbus Mandatory Service Bulletins A330–32–3241 and A340–32– 4282, both dated November 26, 2010, as the appropriate sources of service information for doing the actions specified in the NPRM (76 FR 81884, December 29, 2011). We have updated paragraphs (g) and (j) of this AD to refer to Airbus Mandatory Service Bulletins A330–32–3241 and A340–32–4282, both Revision 01, both including Appendix 01, both dated October 6, 2011. We have also added new paragraph (h) to this AD to give credit for actions done before the effective date of this AD in accordance with Airbus Mandatory Service Bulletins A330–32–3241 and A340–32– 4282, both dated November 26, 2010, and updated subsequent paragraph identifiers accordingly. We also added a reference to Model A330–200 freighter series airplanes in paragraphs (g) and (h) of this AD. 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. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD with the changes described previously and minor editorial changes. We have determined that these changes: • Are consistent with the intent that was proposed in the NPRM (76 FR 81884, December 29, 2011) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (76 FR 81884, December 29, 2011). srobinson on DSK4SPTVN1PROD with RULES Costs of Compliance We estimate that this AD will affect 55 products of U.S. registry. We also estimate that it will take about 66 workhours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $10,000 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 parts. 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 this AD to the U.S. operators to be $858,550, or $15,610 per product. VerDate Mar<15>2010 16:15 May 16, 2012 Jkt 226001 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 that 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); 3. Will not affect intrastate aviation in Alaska; and 4. 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.

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Airbus Model A330-200 freighter series airplanes; Model A330-200 and -
300 series airplanes; and Model A340-200 and -300 series airplanes. 
This AD was prompted by a report of corrosion found on the main fitting 
of the nose landing gear (NLG) leg in the vicinity of the dowel pin 
bushes retaining the lower steering flange. This AD requires modifying 
the NLG main fitting by adding primer paint to the cadmium around the 
dowel bush holes. We are issuing this AD to prevent NLG main fitting 
rupture, which could result in an NLG collapse.

DATES: This AD becomes effective June 21, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 21, 
2012.

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 29, 2011 
(76 FR 81884). That NPRM proposed to correct an unsafe condition for 
the specified products. The MCAI states:

    Corrosion has been found on the main fitting of the NLG leg in 
the vicinity of the dowel pin bushes retaining the lower steering 
flange on A330/A340 aeroplanes. The majority of parts have been 
reworked and returned to service.
    This corrosion, if not avoided, could lead to the NLG main 
fitting rupture, possibly resulting in a NLG collapse, which would 
constitute an unsafe condition.
    In order to maintain the structural integrity of the NLG, this 
[EASA] AD requires the accomplishment of a modification which 
consists in adding primer paint to the cadmium around the dowel bush 
holes on the main fitting, in order to provide further protection 
against cadmium degradation.

    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 (76 FR 81884, December 29, 
2011) or on the determination of the cost to the public.

[[Page 29211]]

Changes to the AD

    Airbus has issued Mandatory Service Bulletins A330-32-3241 and 
A340-32-4282, both Revision 01, both including Appendix 01, both dated 
October 6, 2011, which correct certain aircraft maintenance manual 
references. We referred to Airbus Mandatory Service Bulletins A330-32-
3241 and A340-32-4282, both dated November 26, 2010, as the appropriate 
sources of service information for doing the actions specified in the 
NPRM (76 FR 81884, December 29, 2011). We have updated paragraphs (g) 
and (j) of this AD to refer to Airbus Mandatory Service Bulletins A330-
32-3241 and A340-32-4282, both Revision 01, both including Appendix 01, 
both dated October 6, 2011. We have also added new paragraph (h) to 
this AD to give credit for actions done before the effective date of 
this AD in accordance with Airbus Mandatory Service Bulletins A330-32-
3241 and A340-32-4282, both dated November 26, 2010, and updated 
subsequent paragraph identifiers accordingly.
    We also added a reference to Model A330-200 freighter series 
airplanes in paragraphs (g) and (h) of this AD.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD with the changes described 
previously and minor editorial changes. We have determined that these 
changes:
     Are consistent with the intent that was proposed in the 
NPRM (76 FR 81884, December 29, 2011) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (76 FR 81884, December 29, 2011).

Costs of Compliance

    We estimate that this AD will affect 55 products of U.S. registry. 
We also estimate that it will take about 66 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts will cost about $10,000 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 parts. 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 this AD to the 
U.S. operators to be $858,550, or $15,610 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 that 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);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.
