ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; Model A310 series airplanes; Model A300 B4–600, B4–600R, and F4–600R series airplanes, and Model C4–605R Variant F airplanes (collectively called Model A300–600 series airplanes). This proposed AD was prompted by reports of cracked fuel pump canister hoods located in fuel tanks. This proposed AD would require replacing any hood halves of fuel pump canisters that are cracked. We are proposing this AD to prevent any detached canister hood fragments/debris from being ingested into the fuel feed system, and the metallic debris inside the fuel tank resulting in a potential source of ignition and consequent fire or explosion. SUMMARY: We must receive comments on this proposed AD by April 9, 2012. ADDRESSES: You may send comments by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

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 2011–0124, dated June 30, 2011 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: This [EASA] AD results from findings of cracked fuel pump canister hoods located in fuel tanks. From the analyses, laboratory testing and examinations made so far, it is presently thought that vibration-induced fatigue can be PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 10409 identified as the root cause for the cracks found on in-service aeroplanes. However, current data does not yet permit to exclude some other potential contributing factors. This condition, if not detected and corrected, could lead to detached canister hood fragments/debris to be ingested into the fuel feed system. Also, the metallic debris inside the fuel tank could result in a potential source of ignition and consequent fire or explosion. For the reasons described above, this [EASA] AD requires repetitive [detailed] inspections of all fuel pump canister hood halves and their replacement if any [cracking] damage is found. This [EASA] AD also requires the inspection results to be reported. This [EASA] AD is considered to be an interim action. The reports that are required by this [EASA] AD will enable the manufacturer to obtain better insight into the nature, cause, and extent of the fuel pump canister hood cracking, and eventually to develop final action to address the unsafe condition. Once final action has been identified, further AD actions could be considered. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued Mandatory Service Bulletins A300–28–0089, A300–28– 6106, and A310–28–2173, all including Inspection Findings—Reporting Sheet, all Revision 01, all dated April 15, 2011. 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. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 221 products of U.S. registry. We also estimate that it would take up to 12 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 $225,420, or $1,020 per product. E:\FR\FM\22FEP1.SGM 22FEP1 10410 Federal Register / Vol. 77, No. 35 / Wednesday, February 22, 2012 / Proposed Rules In addition, we estimate that any necessary follow-on actions would take about 1 work-hour. We have no way of determining the number of products that may need these actions. We have received no definitive data that would enable us to provide cost estimates for certain parts required for the on-condition actions (replacing fuel pump canister hood halves) specified in this proposed AD. 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. wreier-aviles on DSK5TPTVN1PROD with PROPOSALS 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 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 proposed AD and placed it in the AD docket.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus Model A300 series airplanes; Model A310 series airplanes; Model 
A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R

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 2011-0124, dated June 30, 2011 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    This [EASA] AD results from findings of cracked fuel pump 
canister hoods located in fuel tanks.
    From the analyses, laboratory testing and examinations made so 
far, it is presently thought that vibration-induced fatigue can be 
identified as the root cause for the cracks found on in-service 
aeroplanes. However, current data does not yet permit to exclude 
some other potential contributing factors.
    This condition, if not detected and corrected, could lead to 
detached canister hood fragments/debris to be ingested into the fuel 
feed system. Also, the metallic debris inside the fuel tank could 
result in a potential source of ignition and consequent fire or 
explosion.
    For the reasons described above, this [EASA] AD requires 
repetitive [detailed] inspections of all fuel pump canister hood 
halves and their replacement if any [cracking] damage is found. This 
[EASA] AD also requires the inspection results to be reported.
    This [EASA] AD is considered to be an interim action. The 
reports that are required by this [EASA] AD will enable the 
manufacturer to obtain better insight into the nature, cause, and 
extent of the fuel pump canister hood cracking, and eventually to 
develop final action to address the unsafe condition. Once final 
action has been identified, further AD actions could be considered.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletins A300-28-0089, A300-
28-6106, and A310-28-2173, all including Inspection Findings--Reporting 
Sheet, all Revision 01, all dated April 15, 2011. 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.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 221 products of U.S. registry. We also estimate that 
it would take up to 12 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 $225,420, or $1,020 per product.

[[Page 10410]]

    In addition, we estimate that any necessary follow-on actions would 
take about 1 work-hour. We have no way of determining the number of 
products that may need these actions.
    We have received no definitive data that would enable us to provide 
cost estimates for certain parts required for the on-condition actions 
(replacing fuel pump canister hood halves) specified in this proposed 
AD.

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 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 proposed AD and placed it in 
the AD docket.

detailed inspection for cracking of the fuel pump canister hood 
halves installed on all fuel pump canisters having part numbers (P/
N) 2052C11, 2052C12, and C93R51-601, in accordance with the 
Accomplishment Instructions of the service bulletin specified in 
paragraphs (g)(1), (g)(2), and (g)(3) of this AD, as applicable. If 
any crack is found on any fuel pump canister hood half during any 
inspection, before further flight, replace the fuel pump canister 
hood half, in accordance with the Accomplishment Instructions of the 
service bulletin specified in paragraph (g)(1), (g)(2), or (g)(3) of 
this AD, as applicable.
