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. You can find our regulatory evaluation and the estimated costs of compliance in the AD Docket.

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 2010–0066, dated April 21, 2010 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Airbus, in the frame of the Extended Service Goal (ESG) exercise, has demonstrated by post-certification analysis that, among the types of yokes in service, one component on the CF6–80C2 forward engine mounts (skinny cast yoke) does not meet the Design Service Goal (DSG) requirements. This condition, if not corrected, could result in a deterioration of the structural integrity of the forward engine mount. For the reasons described above, this AD requires operators to [perform an inspection to determine the part number of the forward engine mount skinny cast yokes,] perform a one time [detailed] inspection [for rupture] of the forward engine mount skinny cast yokes Part Number (P/N) 9383M43G08, 9383M43G09, 9383M43G10 and 9383M43G11 of GE CF6–80C2 powered aeroplanes and to replace the affected skinny cast yokes with forged yokes. Upon replacement of the skinny cast yoke, the General Electric CF6–80C2 Service Bulletin (SB) 72–0222 [installation of a redesigned forward engine mount system] must be completed as a prerequisite. 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. Relevant Service Information Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 53 products of U.S. registry. We also estimate that it would take about 10 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 $45,050, or $850 per product. In addition, we estimate that any necessary follow-on actions would take about 608 work-hours and require parts costing $322,000, for a cost of $373,680 per product. We have no way of determining the number of products that may need these actions. Airbus has issued All Operators Telexes A300–71A6029, including Appendices 01, 02, 03, and 04, dated March 30, 2010; and A310–71A2036, including Appendices 01, 02, 03, and 04, dated March 30, 2010. GE has issued CF6–80C2 Service Bulletin 72–0222, Revision 4, dated February 29, 2000. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. 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: The unsafe condition is possible separation of the engine from the engine mount during flight. You may obtain further information by examining the MCAI in the AD docket. PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 E:\FR\FM\01FEP1.SGM 01FEP1 Federal Register / Vol. 76, No. 21 / Tuesday, February 1, 2011 / Proposed Rules 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.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to amend the airport certification standards in part 139. This action would establish minimum standards for training of personnel who access the airport nonmovement area (ramp and apron) to help prevent accidents and incidents in that area. A certificate holder would be required to conduct pavement surface evaluations to ensure reliability of runway surfaces in wet weather conditions. This action would also require a Surface Movement Guidance Control System (SMGCS) plan if the certificate holder conducts low visibility operations. The plan would facilitate the safe movement of aircraft and vehicles in low visibility conditions.

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:

    Airbus, in the frame of the Extended Service Goal (ESG) 
exercise, has demonstrated by post-certification analysis that, 
among the types of yokes in service, one component on the CF6-80C2 
forward engine mounts (skinny cast yoke) does not meet the Design 
Service Goal (DSG) requirements.
    This condition, if not corrected, could result in a 
deterioration of the structural integrity of the forward engine 
mount.
* * * * *
    The unsafe condition is possible separation of the engine from the 
engine mount during flight. 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 2010-0066, dated April 21, 2010 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    Airbus, in the frame of the Extended Service Goal (ESG) 
exercise, has demonstrated by post-certification analysis that, 
among the types of yokes in service, one component on the CF6-80C2 
forward engine mounts (skinny cast yoke) does not meet the Design 
Service Goal (DSG) requirements.
    This condition, if not corrected, could result in a 
deterioration of the structural integrity of the forward engine 
mount.
    For the reasons described above, this AD requires operators to 
[perform an inspection to determine the part number of the forward 
engine mount skinny cast yokes,] perform a one time [detailed] 
inspection [for rupture] of the forward engine mount skinny cast 
yokes Part Number (P/N) 9383M43G08, 9383M43G09, 9383M43G10 and 
9383M43G11 of GE CF6-80C2 powered aeroplanes and to replace the 
affected skinny cast yokes with forged yokes.
    Upon replacement of the skinny cast yoke, the General Electric 
CF6-80C2 Service Bulletin (SB) 72-0222 [installation of a redesigned 
forward engine mount system] must be completed as a prerequisite.
    The unsafe condition is possible separation of the engine from the 
engine mount during flight. You may obtain further information by 
examining the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued All Operators Telexes A300-71A6029, including 
Appendices 01, 02, 03, and 04, dated March 30, 2010; and A310-71A2036, 
including Appendices 01, 02, 03, and 04, dated March 30, 2010. GE has 
issued CF6-80C2 Service Bulletin 72-0222, Revision 4, dated February 
29, 2000. 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 53 products of U.S. registry. We also estimate that 
it would take about 10 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 $45,050, or $850 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 608 work-hours and require parts costing $322,000, for a 
cost of $373,680 per product. We have no way of determining the number 
of products that may need these actions.

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:

[[Page 5509]]

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.
