The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2010–0171; Directorate Identifier 2009–NM–185–AD] RIN 2120–AA64 Airworthiness Directives; Airbus Model A300 Series Airplanes, Airbus Model A300 B4–600 Series Airplanes, Airbus Model A300 B4–600R Series Airplanes, and A310 Series Airplanes sroberts on DSKD5P82C1PROD with PROPOSALS AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed 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. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI. VerDate Nov<24>2008 17:18 Feb 24, 2010 Jkt 220001 DATES: We must receive comments on this proposed AD by April 12, 2010.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2009–0165, dated July 31, 2009 (referred to after this as ‘‘the MCAI’’), 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. E:\FR\FM\25FEP1.SGM 25FEP1 8550 Federal Register / Vol. 75, No. 37 / Thursday, February 25, 2010 / Proposed Rules 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. Relevant Service Information Airbus has issued the following service bulletins: • Airbus Mandatory Service Bulletin A300–53–0388, including Appendix 01, dated March 17, 2009; • Airbus Mandatory Service Bulletin A300–53–6164, including Appendix 01, dated March 17, 2009; and • Airbus Mandatory Service Bulletin A310–53–2131, including Appendix 01, dated March 17, 2009. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. sroberts on DSKD5P82C1PROD with PROPOSALS 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 proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the proposed AD. Costs of Compliance Based on the service information, we estimate that this proposed AD would VerDate Nov<24>2008 17:18 Feb 24, 2010 Jkt 220001 affect about 206 products of U.S. registry. We also estimate that it would take about 2 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $35,020, or $170 per product, per inspection cycle. 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 The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new AD: Airbus: Docket No. FAA–2010–0171; Directorate Identifier 2009–NM–185–AD. Comments Due Date (a) We must receive comments by April 12, 2010.

The affected Crissair check valves * * * were then replaced with improved check valves P/N [part number] 2S2794–1 * * *. More recently, similar issues were again reported on aeroplanes with Crissair check valves P/N 2S2794–1 installed. The investigations * * * have shown that a spring, mounted inside the valve, does not meet the Airbus type design specifications. This situation, if not corrected, can cause hydraulic system functional degradation, possibly resulting in reduced control of the aeroplane when combined with an air duct leak, air conditioning system contamination or, if installed, malfunction of the fire extinguishing system in the Class ‘C’ cargo compartment. * * * * * The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed 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. The proposed AD would require actions that are intended to 
address the unsafe condition described in the MCAI.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2009-0165, dated July 31, 2009 (referred to 
after this as ``the MCAI''), 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.

[[Page 8550]]

    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.

Relevant Service Information

    Airbus has issued the following service bulletins:
     Airbus Mandatory Service Bulletin A300-53-0388, including 
Appendix 01, dated March 17, 2009;
     Airbus Mandatory Service Bulletin A300-53-6164, including 
Appendix 01, dated March 17, 2009; and
     Airbus Mandatory Service Bulletin A310-53-2131, including 
Appendix 01, dated March 17, 2009.
    The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

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

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 206 products of U.S. registry. We also estimate that 
it would take about 2 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $35,020, or $170 per product, per inspection 
cycle.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    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 proposed AD and placed it in the AD docket.

The Proposed Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

    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]

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

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

Comments Due Date

    (a) We must receive comments by April 12, 2010.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to all Airbus Model A300 B2-1A, B2-1C, B2K-
3C, B2-203, B4-2C, B4-103, B4-203, B4-601, B4-603, B4-620, B4-622, 
B4-605R, B4-622R, F4-605R, F4-622R, C4-605R Variant F airplanes, and 
A310-203, -204, -221, -222, -304, -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

[[Page 8551]]

the compliance times specified, unless the actions have already been 
done.

    (1) At the later of the times specified in paragraph (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.
