SUPPLEMENTARY INFORMATION: FOR FURTHER INFORMATION CONTACT: We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AB412 and AB412EP helicopters with a certain rotor brake pinion installed. This AD requires inspecting the rotor brake pinion for a crack, and replacing it if there is a crack. This AD is prompted by a report of a rotor brake pinion failure. These actions are intended to detect a crack on the rotor brake pinion and prevent failure of the rotor brake pinion, which could lead to detachment of parts inside the transmission and subsequent loss of control of the helicopter. DATES: This AD becomes effective July 7, 2014. We must receive comments on this AD by August 18, 2014. ADDRESSES: You may send comments by any of the following methods: SUMMARY: Examining the AD Docket Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not provide you with notice and an opportunity to provide your comments prior to it becoming effective. However, we invite you to participate in this rulemaking by submitting written comments, data, or views. We also invite comments relating to the economic, environmental, energy, or federalism impacts that resulted from adopting this AD. The most helpful comments reference a specific portion of PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 35035 the AD, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should send only one copy of written comments, or if comments are filed electronically, commenters should submit them only one time. 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 rulemaking during the comment period. We will consider all the comments we receive and may conduct additional rulemaking based on those comments. Discussion This AD is prompted by AD No. 2013–0187, dated August 16, 2013 (AD 2013–0187), issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Agusta Model AB412 and AB412EP helicopters. EASA advises of a report of a cracked pinion, part number (P/N) 412–040–301–101, installed in the rotor brake quill, P/N 412–040–123–103, on an AB412 helicopter. EASA states that the crack was discovered by a magnetic particle inspection during a scheduled overhaul of the rotor brake quill. EASA further states that an investigation revealed the crack was due to residual stress generated during the manufacturing process, and that this condition, if not detected and corrected, could lead to failure of the pinion with detachment of parts inside the transmission that could cause its malfunction or jamming, finally resulting in loss of control of the helicopter. To address this unsafe condition, EASA AD 2013–0187 requires magnetic particle inspecting the rotor brake pinion, and if there is a crack, replacing the rotor brake pinion. FAA’s Determination These helicopters have been approved by the aviation authority of Italy and are approved for operation in the United States. Pursuant to our bilateral agreement with Italy, EASA, its technical representative, has notified us of the unsafe condition described in the EASA AD. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs. Related Service Information Agusta has issued Bollettino Tecnico No. 412–135, Revision A, dated July 29, 2013, which describes procedures for a one-time magnetic particle inspection of the rotor brake pinion, P/N 412–040– E:\FR\FM\19JNR1.SGM 19JNR1 35036 Federal Register / Vol. 79, No. 118 / Thursday, June 19, 2014 / Rules and Regulations 301–101, installed on Model AB412 and AB412EP helicopters. AD Requirements This AD requires, within 100 hours time-in-service, magnetic particle inspecting the rotor brake pinion, P/N 412–040–301–101, for a crack. If there is a crack, this AD requires replacing the pinion before further flight. Differences Between This AD and the EASA AD The EASA AD does not apply to pinions installed in a rotor brake quill assembly that has been overhauled, while this AD does. Costs of Compliance There are no costs of compliance with this AD because there are no helicopters with this type certificate on the U.S. Registry. mstockstill on DSK4VPTVN1PROD with RULES FAA’s Justification and Determination of the Effective Date There are no helicopters with this type certificate on the U.S. Registry. Therefore, we believe it is unlikely that we will receive any adverse comments or useful information about this AD from U.S. operators. Since an unsafe condition exists that requires the immediate adoption of this AD, we determined that notice and opportunity for public comment before issuing this AD are unnecessary because there are none of these products on the U.S. Registry and that good cause exists for making this amendment effective in less than 30 days. 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 AD will not have federalism implications under VerDate Mar<15>2010 16:39 Jun 18, 2014 Jkt 232001 Executive Order 13132. This AD will 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 that this AD: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under 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.

SUPPLEMENTARY INFORMATION:

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments prior to it becoming effective. However, we 
invite you to participate in this rulemaking by submitting written 
comments, data, or views. We also invite comments relating to the 
economic, environmental, energy, or federalism impacts that resulted 
from adopting this AD. The most helpful comments reference a specific 
portion of the AD, explain the reason for any recommended change, and 
include supporting data. To ensure the docket does not contain 
duplicate comments, commenters should send only one copy of written 
comments, or if comments are filed electronically, commenters should 
submit them only one time. 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 rulemaking during the 
comment period. We will consider all the comments we receive and may 
conduct additional rulemaking based on those comments.

Discussion

    This AD is prompted by AD No. 2013-0187, dated August 16, 2013 (AD 
2013-0187), issued by EASA, which is the Technical Agent for the Member 
States of the European Union, to correct an unsafe condition for Agusta 
Model AB412 and AB412EP helicopters. EASA advises of a report of a 
cracked pinion, part number (P/N) 412-040-301-101, installed in the 
rotor brake quill, P/N 412-040-123-103, on an AB412 helicopter. EASA 
states that the crack was discovered by a magnetic particle inspection 
during a scheduled overhaul of the rotor brake quill. EASA further 
states that an investigation revealed the crack was due to residual 
stress generated during the manufacturing process, and that this 
condition, if not detected and corrected, could lead to failure of the 
pinion with detachment of parts inside the transmission that could 
cause its malfunction or jamming, finally resulting in loss of control 
of the helicopter. To address this unsafe condition, EASA AD 2013-0187 
requires magnetic particle inspecting the rotor brake pinion, and if 
there is a crack, replacing the rotor brake pinion.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Italy and are approved for operation in the United States. Pursuant to 
our bilateral agreement with Italy, EASA, its technical representative, 
has notified us of the unsafe condition described in the EASA AD. We 
are issuing this AD because we evaluated all information provided by 
EASA and determined the unsafe condition exists and is likely to exist 
or develop on other helicopters of these same type designs.

Related Service Information

    Agusta has issued Bollettino Tecnico No. 412-135, Revision A, dated 
July 29, 2013, which describes procedures for a one-time magnetic 
particle inspection of the rotor brake pinion, P/N 412-040-

[[Page 35036]]

301-101, installed on Model AB412 and AB412EP helicopters.

AD Requirements

    This AD requires, within 100 hours time-in-service, magnetic 
particle inspecting the rotor brake pinion, P/N 412-040-301-101, for a 
crack. If there is a crack, this AD requires replacing the pinion 
before further flight.

Differences Between This AD and the EASA AD

    The EASA AD does not apply to pinions installed in a rotor brake 
quill assembly that has been overhauled, while this AD does.

Costs of Compliance

    There are no costs of compliance with this AD because there are no 
helicopters with this type certificate on the U.S. Registry.

FAA's Justification and Determination of the Effective Date

    There are no helicopters with this type certificate on the U.S. 
Registry. Therefore, we believe it is unlikely that we will receive any 
adverse comments or useful information about this AD from U.S. 
operators.
    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we determined that notice and opportunity for 
public comment before issuing this AD are unnecessary because there are 
none of these products on the U.S. Registry and that good cause exists 
for making this amendment effective in less than 30 days.

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 AD will not have federalism implications 
under Executive Order 13132. This AD will 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 that this AD:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under 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.
