E:\FR\FM\25NOR1.SGM 25NOR1 Federal Register / Vol. 78, No. 227 / Monday, November 25, 2013 / Rules and Regulations SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to the specified products. The NPRM was published in the Federal Register on August 5, 2013 (78 FR 47228). The NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: A power loss event was reported on an aeroplane equipped with a TAE 125–01 engine. The investigation results showed that the probable cause was contamination of the engine clutch by coolant spillage during the last maintenance operation. The contamination penetrated the clutch housing through an opening located under the coolant tank that was only closed by a not fluid-tight plastic cover. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov/ #!documentDetail;D=FAA-2013-05610002. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (78 FR 47228, August 5, 2013). Conclusion We reviewed the available data and determined that air safety and the public interest require adopting this AD as proposed. Costs of Compliance We estimate that this AD will affect about 140 engines of U.S. registry. We also estimate that it will take about 2.5 hours per engine to comply with this AD. The average labor rate is $85 per hour. Required parts cost about $110 per engine. Based on these figures, we estimate the cost of this AD on U.S. operators to be $45,150. emcdonald on DSK67QTVN1PROD with RULES Authority for This Rulemaking 15:59 Nov 22, 2013 Jkt 232001 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 above, I certify this AD: (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.

Basis and Purpose [Docket No. USCG–2013–0639] RIN 1625–AA09 Drawbridge Operation Regulation; Hackensack River, Kearney and Jersey City, NJ Coast Guard, DHS. Temporary final rule. The Coast Guard is temporarily modifying the operating schedule that governs the operation of the Route 1 & 9 (Lincoln Highway) Bridge across the Hackensack River, mile 2.0, between Kearny and Jersey City, New Jersey. The bridge owner, New Jersey Department of Transportation, submitted a request to restrict bridge openings during the morning and afternoon rush hour periods to alleviate traffic congestion resulting from area roadway closures. It is expected that this change to the regulations would provide relief to vehicular traffic while continuing to meet the reasonable needs of navigation.

FOR FURTHER INFORMATION CONTACT: If you have questions on this temporary final rule, call or email Mr. Joe Arca, Project Officer, First Coast Guard District Bridge Branch, 212–668–7165, emcdonald on DSK67QTVN1PROD with RULES SUMMARY: VerDate Mar<15>2010 15:59 Nov 22, 2013 Jkt 232001 The Route 1 & 9 (Lincoln Highway) Bridge at mile 2.0, across the Hackensack River between Kearny and Jersey City, New Jersey, has a vertical clearance of 40 feet at mean high water and 45 feet at mean low water. The drawbridge operation regulations are listed at 33 CFR 117.723. The waterway users are predominantly recreational vessels and commercial vessels. The owner of the bridge, New Jersey Department of Transportation, submitted a request to the Coast Guard to temporarily change the drawbridge operating regulations. The purpose of this temporary final rule is to help provide relief to help reduce vehicular traffic congestion during the morning and afternoon vehicular rush hour periods. Additional vehicular traffic will be detoured across the Route 1 & 9 (Lincoln Highway) Bridges for two years from the adjacent Pulaski Skyway Bridge which will be under construction to replace its deck commencing on March 1, 2014 and continuing through March 1, 2016. The existing regulations presently require the bridge to open on signal at all times. Under this temporary final rule the draw shall open on signal; except that, the draw need not open for the passage of vessel traffic between 6 a.m. and 10 a.m. and 2 p.m. and 6 p.m., Monday through Friday, except holidays. Tide dependent deep draft vessels may request bridge openings during the two rush hour closure periods provided at least a twelve hour advance notice is given. PO 00000 Frm 00028 Fmt 4700 Sfmt 4700 C. Discussion of Comments, Changes and the Final Rule The Coast Guard received no comments in response to the notice of proposed rulemaking. As a result, no changes have been made to this final rule. D. Regulatory Analyses We developed this rule after considering numerous statutes and executive orders related to rulemaking. Below we summarize our analyses based on these statutes or executive orders. 1. Regulatory Planning and Review This rule is not a significant regulatory action under section 3(f) of Executive Order 12866, Regulatory Planning and Review, and does not require an assessment of potential costs and benefits under section 6(a)(3) of that Order. The Office of Management and Budget has not reviewed it under that Order. We believe that this rule is not a significant regulatory action because the bridge provides adequate clearance for recreational vessels in the closed position and the commercial vessels will be able to get openings at any time provided the advance notice is given by calling the number posted at the bridge. 2. Impact on Small Entities The Regulatory Flexibility Act of 1980 (RFA), 5 U.S.C. 601–612, as amended, requires federal agencies to consider the potential impact of regulations on small entities during rulemaking. The Coast Guard received no comments from the Small Business Administration on this rule. The Coast Guard certifies under 5 U.S.C. 605(b) that this rule will not have a significant economic impact on a substantial number of small entities. This rule should not have a significant effect on small entities since the bridge provides 40 feet of vertical clearance at mean high water which should accommodate the recreational vessels that transit this waterway. Deep draft commercial vessels can transit at during the two rush hour closure periods provided they give the twelve hour advance notice for openings. There is no permanent restriction or regulation being imposed by this rule; therefore, the Coast Guard certifies under 5 U.S.C. 605(b) that this temporary final rule will not have a significant economic impact on a substantial number of small entities. 3. Assistance for Small Entities Under section 213(a) of the Small Business Regulatory Enforcement Fairness Act of 1996 (Pub. L. 104–121), we want to assist small entities in E:\FR\FM\25NOR1.SGM 25NOR1

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Thielert Aircraft Engines GmbH TAE 125-01 reciprocating engines. This 
AD requires applying sealant to close the engine clutch housing 
(crankcase assembly) opening. This AD was prompted by a report of 
engine power loss due to engine coolant contaminating the engine 
clutch. The design of the engine allows the crankcase assembly opening 
to be susceptible to contamination from external sources. We are 
issuing this AD to prevent in-flight engine power loss, which could 
result in loss of control of, and damage to, the airplane.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to the specified products. The 
NPRM was published in the Federal Register on August 5, 2013 (78 FR 
47228). The NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    A power loss event was reported on an aeroplane equipped with a 
TAE 125-01 engine. The investigation results showed that the 
probable cause was contamination of the engine clutch by coolant 
spillage during the last maintenance operation. The contamination 
penetrated the clutch housing through an opening located under the 
coolant tank that was only closed by a not fluid-tight plastic 
cover.

    You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov/#!documentDetail;D=FAA-2013-0561-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 47228, August 5, 
2013).

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed.

Costs of Compliance

    We estimate that this AD will affect about 140 engines of U.S. 
registry. We also estimate that it will take about 2.5 hours per engine 
to comply with this AD. The average labor rate is $85 per hour. 
Required parts cost about $110 per engine. Based on these figures, we 
estimate the cost of this AD on U.S. operators to be $45,150.

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 above, I certify this AD:
    (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 a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.
