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 2011–0204, dated October 14, 2011 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: During a production test flight, a Ram Air Turbine (RAT) did not deploy when tested. An investigation, conducted by the RAT manufacturer Hamilton Sundstrand (HS) and Arkwin Industries, revealed that the RAT did not deploy due to insufficient stroke inside one of the actuator deployment solenoids. This condition, if occurring following a total engine flame out, or during a total loss of normal electrical power generation, could possibly result in reduced control of the aeroplane. For the reasons described above, this [EASA] AD requires the modification of the affected RAT actuator deployment mechanism, or replacement of the RAT actuator with a modified unit. The required actions include identification of the supplier, part number, and serial number of the installed RAT actuator, and reidentification of the actuator and RAT, or replacement of the RAT actuator with a serviceable unit and re-identification of the RAT, if necessary. 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 A330–29–3114, dated May 18, 2011. • Airbus Mandatory Service Bulletin A340–29–4089, dated May 18, 2011. • Airbus Mandatory Service Bulletin A340–29–5018, dated May 18, 2011. Hamilton Sundstrand has issued the following service bulletins: • Hamilton Sundstrand Service Bulletin ERPS06M–29–18, dated March 8, 2011. • Hamilton Sundstrand Service Bulletin ERPS33T–29–5, dated March 8, 2011. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. E:\FR\FM\18JNP1.SGM 18JNP1 36210 Federal Register / Vol. 77, No. 117 / Monday, June 18, 2012 / Proposed Rules FAA’s Determination and Requirements of This Proposed AD products identified in this rulemaking action. 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. Regulatory Findings Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 56 products of U.S. registry. We also estimate that it would take about 14 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $0 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 the proposed AD on U.S. operators to be $66,640, or $1,190 per product. In addition, we estimate that any necessary follow-on actions would take about 13 work-hours and require parts costing $0, for a cost of $1,105 per product. We have no way of determining the number of products that may need these actions. TKELLEY on DSK3SPTVN1PROD with PROPOSALS 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 VerDate Mar<15>2010 17:54 Jun 15, 2012 Jkt 226001 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); 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.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt 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, -300, -500, and -600 
series airplanes. This proposed AD was prompted by reports of the ram 
air turbine (RAT) not deploying when tested. This proposed AD would 
require identification of the supplier, part number, and serial number 
of the installed RAT actuator, and re-identification of the actuator 
and RAT, or replacement of the RAT actuator with a serviceable unit and 
re-identification of the RAT, if necessary. We are proposing this AD to 
prevent non-deployment of the RAT, which if occurred following a total 
engine flame-out, or during a total loss of normal electrical power 
generation, could result in reduced control of the airplane.

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 2011-0204, dated October 14, 2011 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    During a production test flight, a Ram Air Turbine (RAT) did not 
deploy when tested. An investigation, conducted by the RAT 
manufacturer Hamilton Sundstrand (HS) and Arkwin Industries, 
revealed that the RAT did not deploy due to insufficient stroke 
inside one of the actuator deployment solenoids.
    This condition, if occurring following a total engine flame out, 
or during a total loss of normal electrical power generation, could 
possibly result in reduced control of the aeroplane.
    For the reasons described above, this [EASA] AD requires the 
modification of the affected RAT actuator deployment mechanism, or 
replacement of the RAT actuator with a modified unit.

The required actions include identification of the supplier, part 
number, and serial number of the installed RAT actuator, and re-
identification of the actuator and RAT, or replacement of the RAT 
actuator with a serviceable unit and re-identification of the RAT, if 
necessary. You may obtain further information by examining the MCAI in 
the AD docket.

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 56 products of U.S. registry. We also estimate that 
it would take about 14 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Required parts would cost about $0 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 the proposed AD on U.S. operators to 
be $66,640, or $1,190 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 13 work-hours and require parts costing $0, for a cost of 
$1,105 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: 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);
    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.
