14 CFR Part 39



[Docket No. FAA-2010-0171; Directorate Identifier 2009-NM-185-AD; 

Amendment 39-16329; AD 2010-12-08]

RIN 2120-AA64




Airworthiness Directives; Airbus Model A300 Series Airplanes; 

Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and 

Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series 

Airplanes); and Model A310 Series 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:



    During a maintenance check performed by an A310 operator, the 

recommended modification of the lower attachment beam of rack 101VU 

by accomplishment of Airbus Service Bulletin (SB) A310-53-2076 was 

embodied on the aeroplane, leading the operator to find three cracks 

on the FR15A crossbeam above the NLG [nose landing gear] box at the 

splicing with rack 107VU fitting.

    This condition, if not detected and corrected, could degrade the 

structural integrity of the crossbeam on NLG FR15A Web attachment 

fitting of rack 107VU. Rack 107VU contains major airworthiness 

system components whose functioning could be adversely affected by 

the loss of the attachment fitting.

    As the A300 and A300-600 aeroplanes share this design feature, 

they are also affected.



* * * * *

We are issuing this AD to require actions to correct the unsafe 

condition on these products.



DATES: This AD becomes effective July 13, 2010.

    The Director of the Federal Register approved the incorporation by 

reference of certain publications listed in this AD as of July 13, 

2010.



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 February 25, 2010 

(75 FR 8549). That NPRM proposed to correct an unsafe condition for the 

specified products. The MCAI states:



    During a maintenance check performed by an A310 operator, the 

recommended modification of the lower attachment beam of rack 101VU 

by accomplishment of Airbus Service Bulletin (SB) A310-53-2076 was 

embodied on the aeroplane, leading the operator to find three cracks 

on the FR15A crossbeam above the NLG [nose landing gear] box at the 

splicing with rack 107VU fitting.

    This condition, if not detected and corrected, could degrade the 

structural integrity of the crossbeam on NLG FR15A Web attachment 

fitting of rack 107VU. Rack 107VU contains major airworthiness 

system components whose functioning could be adversely affected by 

the loss of the attachment fitting.

    As the A300 and A300-600 aeroplanes share this design feature, 

they are also affected.

    For the reasons stated above, this AD requires repetitive 

inspections for cracks of the crossbeam on NLG FR15A Web face 

attachment fitting of rack 107VU and corrective action, depending on 

findings.



The corrective actions include contacting Airbus for repair 

instructions, and doing the repair if any crack is found. 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. The commenter, FedEx 

Express, supports the NPRM.



Explanation of Change Made to This AD



    We have revised the subject header of this AD to identify the 

affected airplane models as published in the most recent type 

certificate data sheet.



Conclusion



    We reviewed the available data, including the comment received, 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 206 products of U.S. registry. 

We also estimate that it will take about 2 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 $35,020, or $170 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.



[[Page 32267]]



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.

322, -324, and -325 airplanes; certificated in any category.



Subject



    (d) Air Transport Association (ATA) of America Code 53: 

Fuselage.



Reason



    (e) The mandatory continuing airworthiness information (MCAI) 

states:



    During a maintenance check performed by an A310 operator, the 

recommended modification of the lower attachment beam of rack 101VU 

by accomplishment of Airbus Service Bulletin (SB) A310-53-2076 was 

embodied on the aeroplane, leading the operator to find three cracks 

on the FR15A crossbeam above the NLG [nose landing gear] box at the 

splicing with rack 107VU fitting.

    This condition, if not detected and corrected, could degrade the 

structural integrity of the crossbeam on NLG FR15A Web attachment 

fitting of rack 107VU. Rack 107VU contains major airworthiness 

system components whose functioning could be adversely affected by 

the loss of the attachment fitting.

    As the A300 and A300-600 aeroplanes share this design feature, 

they are also affected.

    For the reasons stated above, this AD requires repetitive 

inspections for cracks of the crossbeam on NLG FR15A Web face 

attachment fitting of rack 107VU and corrective action, depending on 

findings.



The corrective actions include contacting Airbus for repair 

instructions, and doing the repair if any crack is found.



Compliance



    (f) You are responsible for having the actions required by this 

AD performed within the compliance times specified, unless the 

actions have already been done.



Actions



    (g) Do the following actions.

    (1) At the later of the times specified in paragraphs (g)(1)(i) 

and (g)(1)(ii) of this AD: Do a detailed inspection for cracks of 

the crossbeam on the nose landing gear FR15A Web attachment fitting 

of rack 107VU, in accordance with the Accomplishment Instructions in 

the applicable service bulletin specified in Table 1 of this AD.

    (i) Before the accumulation of 6,600 total flight cycles.

    (ii) Within 2,300 flight cycles or 30 months after the effective 

date of this AD, whichever occurs first.

    (2) Thereafter, at intervals not to exceed 2,300 flight cycles, 

repeat the inspection specified in paragraph (g)(1) of this AD.
