SUPPLEMENTARY INFORMATION: On October 3, 2012, the NRC received a PRM filed by Thomas King requesting the NRC take immediate action to address and curtail the use of new synthetic drugs at nuclear power plants. The NRC requirements in Part 26 of Title 10 of the Code of Federal Regulations (10 CFR), ‘‘Fitness for Duty Program,’’ already enable licensees and other affected entities to add other drugs that are scheduled in the Controlled Substances Act to the panel of substances tested pursuant to 10 CFR 26.31(d)(1)(i). However, the NRC has determined that the broader issue of synthetic drug use raised by the petitioner is appropriate for consideration and will address it in the ongoing 10 CFR part 26 Drug and Alcohol Testing; Technical Issues and Editorial Changes rulemaking. Therefore, the NRC is not instituting an opportunity for public comment at this time. Stakeholders will have an opportunity to comment on the proposed rule associated with 10 CFR part 26 Drug and Alcohol Testing; Technical Issues and Editorial Changes.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2010– 0154, dated August 13, 2010, to correct an unsafe condition for Eurocopter Model MBB–BK 117 C–2, EC135, and EC635 series helicopters. EASA AD No. 2010–0154 supersedes EASA AD No. 2009–0093–E, dated April 17, 2009. EASA advises that cracks were detected on the boom, part number (P/N) 44307– 500, during a pre-flight check of the hoist on a Model MBB–BK 117 C–2 helicopter. EASA advises that this condition, if not detected and corrected, would impair the structural strength of the boom and could lead to failure of the boom. EASA advises that this could result in the loss of the boom and attached loads. According to EASA, boom P/Ns 44301–500 and 44307–500– 1 are of similar design to P/N 44307– 500, and therefore are also subject to this unsafe condition. As a result, EASA issued Emergency AD No. 2009–0093–E to require repetitive visual checks of the affected boom and removal or replacement of the boom when cracks are found. EASA advises that since AD No. 2009–0093–E was issued, further technical investigation determined that torque values that were too high have been applied. EASA advises that Goodrich Corporation, manufacturer of the affected booms, has developed an inspection that will determine the need for further action. As a result, EASA superseded its AD to include a new inspection to detect damage, by issuing EASA AD No. 2010–0154. The EASA AD states that if no damage is found during this new inspection, that constitutes terminating action. FAA’s Determination These helicopters have been approved by the aviation authority of Germany and are approved for operation in the United States. Pursuant to our bilateral agreement with Germany, EASA, its technical representative, has notified us of the unsafe condition described in its AD. We are proposing this AD because PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of the same type design. Related Service Information Eurocopter has issued Emergency Alert Service Bulletin (EASB) No. EC135–85A–036, Revision 2, dated June 23, 2010, and EASB No. MBB BK117 C– 2–85A–024, Revision 1, dated June 23, 2010, which specify a visual check of the boom for cracks, and removing or replacing the boom before the next flight if there is a crack. The EASBs also require compliance with the visual and dye penetrant inspection procedures specified in Goodrich Corporation Service Bulletin 44307–500–03, Revision 2, dated April 30, 2010. EASA classified these EASBs as mandatory, and issued EASA AD No. 2010–0154, dated August 13, 2010, to ensure the continued airworthiness of these helicopters. Proposed AD Requirements This proposed AD would require: • Before further flight, and thereafter before the first flight of each day until the dye penetrant inspection is performed, visually checking the boom for a crack. A pilot holding at least a private pilot certificate may perform this check and must record his or her compliance in the aircraft’s maintenance records in accordance with applicable regulations. A pilot may perform this check because it involves only looking at the boom and can be performed equally well by a pilot or a mechanic. This check is an exception to our standard maintenance regulations. • Within 30 days, performing a dye penetrant inspection of the boom for a crack. • If a crack exists in a boom, replacing the cracked boom with an airworthy boom. Differences Between This Proposed AD and the EASA AD The EASA AD requires you to notify and return parts to the manufacturer, and this proposed AD does not. The EASA AD also applies to the Eurocopter EC635 series military helicopters, while this proposed AD would not because those models are not type certificated in the United States. Costs of Compliance We estimate that this proposed AD would affect 350 helicopters of U.S. Registry and a labor rate of $85 per work-hour. Based on these estimates, we expect the following costs: E:\FR\FM\15APP1.SGM 15APP1 Federal Register / Vol. 78, No. 72 / Monday, April 15, 2013 / Proposed Rules • We estimate that the cost of the daily visual check would be minimal. • We estimate that removing the hoist and boom assembly, performing the dye penetrant inspection, and reinstalling the equipment would require 1.5 work hours. No parts would be needed, for a total cost of about $128 per helicopter and $44,800 for the U.S. fleet. • Replacing the hoist and boom assembly, if needed, would require about a 0.33 work-hour for a labor cost of about $28. Parts would cost $10,833 for a total cost of $10,861 per helicopter. 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. mstockstill on DSK4VPTVN1PROD 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 VerDate Mar<15>2010 16:18 Apr 12, 2013 Jkt 229001 22211 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

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
No. 2010-0154, dated August 13, 2010, to correct an unsafe condition 
for Eurocopter Model MBB-BK 117 C-2, EC135, and EC635 series 
helicopters. EASA AD No. 2010-0154 supersedes EASA AD No. 2009-0093-E, 
dated April 17, 2009. EASA advises that cracks were detected on the 
boom, part number (P/N) 44307-500, during a pre-flight check of the 
hoist on a Model MBB-BK 117 C-2 helicopter. EASA advises that this 
condition, if not detected and corrected, would impair the structural 
strength of the boom and could lead to failure of the boom. EASA 
advises that this could result in the loss of the boom and attached 
loads. According to EASA, boom P/Ns 44301-500 and 44307-500-1 are of 
similar design to P/N 44307-500, and therefore are also subject to this 
unsafe condition. As a result, EASA issued Emergency AD No. 2009-0093-E 
to require repetitive visual checks of the affected boom and removal or 
replacement of the boom when cracks are found.
    EASA advises that since AD No. 2009-0093-E was issued, further 
technical investigation determined that torque values that were too 
high have been applied. EASA advises that Goodrich Corporation, 
manufacturer of the affected booms, has developed an inspection that 
will determine the need for further action. As a result, EASA 
superseded its AD to include a new inspection to detect damage, by 
issuing EASA AD No. 2010-0154. The EASA AD states that if no damage is 
found during this new inspection, that constitutes terminating action.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Germany and are approved for operation in the United States. Pursuant 
to our bilateral agreement with Germany, EASA, its technical 
representative, has notified us of the unsafe condition described in 
its AD. We are proposing this AD because we evaluated all known 
relevant information and determined that an unsafe condition is likely 
to exist or develop on other products of the same type design.

Related Service Information

    Eurocopter has issued Emergency Alert Service Bulletin (EASB) No. 
EC135-85A-036, Revision 2, dated June 23, 2010, and EASB No. MBB BK117 
C-2-85A-024, Revision 1, dated June 23, 2010, which specify a visual 
check of the boom for cracks, and removing or replacing the boom before 
the next flight if there is a crack. The EASBs also require compliance 
with the visual and dye penetrant inspection procedures specified in 
Goodrich Corporation Service Bulletin 44307-500-03, Revision 2, dated 
April 30, 2010. EASA classified these EASBs as mandatory, and issued 
EASA AD No. 2010-0154, dated August 13, 2010, to ensure the continued 
airworthiness of these helicopters.

Proposed AD Requirements

    This proposed AD would require:
     Before further flight, and thereafter before the first 
flight of each day until the dye penetrant inspection is performed, 
visually checking the boom for a crack. A pilot holding at least a 
private pilot certificate may perform this check and must record his or 
her compliance in the aircraft's maintenance records in accordance with 
applicable regulations. A pilot may perform this check because it 
involves only looking at the boom and can be performed equally well by 
a pilot or a mechanic. This check is an exception to our standard 
maintenance regulations.
     Within 30 days, performing a dye penetrant inspection of 
the boom for a crack.
     If a crack exists in a boom, replacing the cracked boom 
with an airworthy boom.

Differences Between This Proposed AD and the EASA AD

    The EASA AD requires you to notify and return parts to the 
manufacturer, and this proposed AD does not. The EASA AD also applies 
to the Eurocopter EC635 series military helicopters, while this 
proposed AD would not because those models are not type certificated in 
the United States.

Costs of Compliance

    We estimate that this proposed AD would affect 350 helicopters of 
U.S. Registry and a labor rate of $85 per work-hour. Based on these 
estimates, we expect the following costs:

[[Page 22211]]

     We estimate that the cost of the daily visual check would 
be minimal.
     We estimate that removing the hoist and boom assembly, 
performing the dye penetrant inspection, and reinstalling the equipment 
would require 1.5 work hours. No parts would be needed, for a total 
cost of about $128 per helicopter and $44,800 for the U.S. fleet.
     Replacing the hoist and boom assembly, if needed, would 
require about a 0.33 work-hour for a labor cost of about $28. Parts 
would cost $10,833 for a total cost of $10,861 per helicopter.

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.

Model EC135 P1, EC135 P2, EC135 P2+, EC135 T1, EC135 T2 and EC135 
T2+ helicopters with a Goodrich Corporation (Goodrich) external 
mounted hoist system (hoist) with boom support assembly (boom) Part 
Number (P/N) 44301-500, 44307-500, or 44307-500-1 installed, and 
Model MBB-BK 117 C-2 helicopters with a Goodrich hoist with boom P/N 
44307-500 installed, certificated in any category.

(b) Unsafe Condition

    This AD defines the unsafe condition as a crack in the boom. 
This condition could result in loss of the boom and attached loads, 
and subsequent loss of helicopter control.

(c) Reserved

(d) Compliance

    You are responsible for performing each action required by this 
AD within the specified compliance time unless it has already been 
accomplished prior to that time.

(e) Required Actions

    (1) Before further flight, and thereafter before the first 
flight of each day until you have performed the inspection required 
by paragraph (e)(2) of this AD, clean the hoist and visually check 
for a crack, paying particular attention to the areas that are 
circled as depicted in Figure 1 to paragraph (e) of this AD. The 
actions required by this paragraph may be performed by the owner/
operator (pilot) holding at least a private pilot certificate, and 
must be entered into the aircraft records showing compliance with 
this AD in accordance with 14 CFR 43.9 (a)(1)-(4) and 14 CFR 91.417 
(a)(2)(v). The record must be maintained as required by 14 CFR
