ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for Model R22, R22 Alpha, R22 Beta, and R22 Mariner helicopters with certain fuel shut-off valves installed. This proposed AD would require replacing the fuel shut-off valve with a newer design fuel shut-off valve. This proposed AD is prompted by three accidents that occurred because the fuel shut-off valve was inadvertently moved to the ‘‘off’’ position. The proposed actions are intended to prevent inadvertent closing of the fuel valve, which could result in engine power loss and subsequent loss of control of the helicopter. DATES: We must receive comments on this proposed AD by June 24, 2013. ADDRESSES: You may send comments by any of the following methods: • Federal eRulemaking Docket: Go to http://www.regulations.gov.

We will file in the docket all comments that we receive, as well as a report summarizing each substantive public contact with FAA personnel concerning this proposed rulemaking. Before acting on this proposal, we will consider all comments we receive on or before the closing date for comments. We will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. We may change this proposal in light of the comments we receive. Discussion Three accidents have occurred with R22 helicopters because the leverhandle fuel valve was inadvertently moved to the ‘‘off’’ position before E:\FR\FM\25APP1.SGM 25APP1 24372 Federal Register / Vol. 78, No. 80 / Thursday, April 25, 2013 / Proposed Rules takeoff. Closing this valve will result in loss of power from the engine and subsequent loss of control of the helicopter. Robinson has subsequently re-designed the fuel valve with a smaller actuating handle and the valve spring loaded to the ‘‘on’’ position, to prevent inadvertent fuel shut-off. FAA’s Determination We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition exists and is likely to exist or develop on other helicopters of the same type design. Related Service Information Robinson has issued R22 Service Bulletin SB–105, dated September 7, 2011 (SB–105), which specifies procedures to replace the lever handle fuel shut-off valve part number (P/N) A670–1 revision A through H with a fuel shut-off valve P/N A670–1 revision I or later. Proposed AD Requirements This proposed AD would require, within 3 years, removing the fuel shutoff valve, P/N A670–1 revision A through H, and replacing the valve with a newly designed fuel shut-off valve. Differences Between This Proposed AD and the Service Information SB–105 specifies compliance within 500 flight-hours or by August 31, 2012. The proposed AD would require compliance within 3 years. Costs of Compliance We estimate that this proposed AD would affect 1,282 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. Replacing the fuel shut-off valve will require about 2 work-hours at an average labor rate of $85 per hour, and required parts would cost about $260, for a cost per helicopter of $430, and a total cost to U.S. operators of $551,260. wreier-aviles on DSK5TPTVN1PROD 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 VerDate Mar<15>2010 15:04 Apr 24, 2013 Jkt 229001 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, 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 to the extent that it justifies making a regulatory distinction; 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 an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

Discussion

    Three accidents have occurred with R22 helicopters because the 
lever-handle fuel valve was inadvertently moved to the ``off'' position 
before

[[Page 24372]]

takeoff. Closing this valve will result in loss of power from the 
engine and subsequent loss of control of the helicopter. Robinson has 
subsequently re-designed the fuel valve with a smaller actuating handle 
and the valve spring loaded to the ``on'' position, to prevent 
inadvertent fuel shut-off.

FAA's Determination

    We are proposing this AD because we evaluated all known relevant 
information and determined that an unsafe condition exists and is 
likely to exist or develop on other helicopters of the same type 
design.

Related Service Information

    Robinson has issued R22 Service Bulletin SB-105, dated September 7, 
2011 (SB-105), which specifies procedures to replace the lever handle 
fuel shut-off valve part number (P/N) A670-1 revision A through H with 
a fuel shut-off valve P/N A670-1 revision I or later.

Proposed AD Requirements

    This proposed AD would require, within 3 years, removing the fuel 
shut-off valve, P/N A670-1 revision A through H, and replacing the 
valve with a newly designed fuel shut-off valve.

Differences Between This Proposed AD and the Service Information

    SB-105 specifies compliance within 500 flight-hours or by August 
31, 2012. The proposed AD would require compliance within 3 years.

Costs of Compliance

    We estimate that this proposed AD would affect 1,282 helicopters of 
U.S. Registry. We estimate that operators may incur the following costs 
in order to comply with this AD. Replacing the fuel shut-off valve will 
require about 2 work-hours at an average labor rate of $85 per hour, 
and required parts would cost about $260, for a cost per helicopter of 
$430, and a total cost to U.S. operators of $551,260.

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, 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 to the extent that 
it justifies making a regulatory distinction; 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 an economic evaluation of the estimated costs to comply 
with this proposed AD and placed it in the AD docket.
