SUPPLEMENTARY INFORMATION: Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2017– 0197, dated October 6, 2017 (referred to after this as the MCAI), to address an unsafe condition for the specified products. The MCAI states: An engine mainline bearing failure occurred on a Viper Mk. 632–43 engine because of debris being present in the engine oil system. The debris entered the oil system through a damaged oil pressure filter. Further investigation of this event revealed that, although the oil pump assembly was of postmodification (mod) CV4559 standard, the oil pressure filter fitted on the oil pump assembly was a pre-mod CV 4559 standard (Part Number (P/N) V21264). The purpose of modification CV4559 is to replace the oil pressure filter P/N V21264 with a more robust oil pressure filter (P/N 2526). Mod CV4559 was introduced in service by R–R Service Bulletin (SB) 72–198. This condition, if not detected and corrected, could lead to an engine mainline bearing failure, possibly resulting in a complete loss of thrust and consequent reduced control of the aeroplane. To address this potentially unsafe condition, R–R issued Alert SB 72–A208, providing instructions to identify and replace pre-modification oil filters. For the reason described above, this [EASA] AD requires replacement of all oil PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 21169 pressure filters P/N V21264 found to be installed on post-mod CV4559 oil pump assemblies. This AD also requires replacement of all pre-mod CV4559 oil pump assemblies (P/N V112027) with post-mod oil pump assemblies (P/N V112225 or P/N NPN11962). You may obtain further information by examining the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2018– 0287. Related Service Information Under 1 CFR Part 51 We reviewed RR Alert Service Bulletin (ASB) Mk. 601–22 Number 72– A208, dated September 2017. The ASB describes procedures for inspecting and replacing a pre-modification oil pump assembly and oil pressure filter with parts eligible for installation. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. FAA’s Determination This product has been approved by EASA and is approved for operation in the United States. Pursuant to our bilateral agreement with the European Community, EASA has notified us of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all the relevant information provided by EASA and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. AD Requirements This AD requires inspecting the oil pump assembly and oil pressure filter and replacing pre-modification parts with parts eligible for installation. FAA’s Justification and Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because the compliance time for the action is less than the time required for public comment. EASA made a determination of an unsafe condition warranting regulatory action and compliance within 25 flight hours or 30 days. Therefore, we find good cause that notice and opportunity for prior public comment are impracticable. In addition, for the reason stated above, we find that E:\FR\FM\09MYR1.SGM 09MYR1 21170 Federal Register / Vol. 83, No. 90 / Wednesday, May 9, 2018 / Rules and Regulations good cause exists for making this amendment effective in less than 30 days.

Background Information and Regulatory History The Coast Guard is issuing this temporary final rule without prior notice and opportunity to comment pursuant to authority under section 4(a) of the Administrative Procedure Act (APA) (5 U.S.C. 553(b)). This provision authorizes an agency to issue a rule without prior notice and opportunity to comment when the agency, for good cause, finds that those procedures are ‘‘impracticable, unnecessary, or contrary to the public interest.’’ Under 5 U.S.C. 553(b)(3)(B), the Coast Guard finds that good cause exists for not publishing a notice of proposed rulemaking (NPRM) with respect to this rule because it is impracticable. The Coast Guard did not receive the event details in sufficient time to publish an NPRM. We must establish this special local regulation on May 12, 2018 and lack sufficient time to provide a reasonable comment period and then consider those comments before issuing this rule. The NPRM process would delay the establishment of the regulated area until after the date of the regatta and compromise public safety.

SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2017-0197, dated October 6, 2017 (referred to after this as the 
MCAI), to address an unsafe condition for the specified products. The 
MCAI states:

    An engine mainline bearing failure occurred on a Viper Mk. 632-
43 engine because of debris being present in the engine oil system. 
The debris entered the oil system through a damaged oil pressure 
filter. Further investigation of this event revealed that, although 
the oil pump assembly was of post-modification (mod) CV4559 
standard, the oil pressure filter fitted on the oil pump assembly 
was a pre-mod CV 4559 standard (Part Number (P/N) V21264). The 
purpose of modification CV4559 is to replace the oil pressure filter 
P/N V21264 with a more robust oil pressure filter (P/N 2526). Mod 
CV4559 was introduced in service by R-R Service Bulletin (SB) 72-
198.
    This condition, if not detected and corrected, could lead to an 
engine mainline bearing failure, possibly resulting in a complete 
loss of thrust and consequent reduced control of the aeroplane.
    To address this potentially unsafe condition, R-R issued Alert 
SB 72-A208, providing instructions to identify and replace pre-
modification oil filters.
    For the reason described above, this [EASA] AD requires 
replacement of all oil pressure filters P/N V21264 found to be 
installed on post-mod CV4559 oil pump assemblies. This AD also 
requires replacement of all pre-mod CV4559 oil pump assemblies (P/N 
V112027) with post-mod oil pump assemblies (P/N V112225 or P/N 
NPN11962).

    You may obtain further information by examining the MCAI in the AD 
docket on the internet at https://www.regulations.gov by searching for 
and locating Docket No. FAA-2018-0287.

Related Service Information Under 1 CFR Part 51

    We reviewed RR Alert Service Bulletin (ASB) Mk. 601-22 Number 72-
A208, dated September 2017. The ASB describes procedures for inspecting 
and replacing a pre-modification oil pump assembly and oil pressure 
filter with parts eligible for installation. This service information 
is reasonably available because the interested parties have access to 
it through their normal course of business or by the means identified 
in the ADDRESSES section.

FAA's Determination

    This product has been approved by EASA and is approved for 
operation in the United States. Pursuant to our bilateral agreement 
with the European Community, EASA has notified us of the unsafe 
condition described in the MCAI and service information referenced 
above. We are issuing this AD because we evaluated all the relevant 
information provided by EASA and determined the unsafe condition 
described previously is likely to exist or develop in other products of 
the same type design.

AD Requirements

    This AD requires inspecting the oil pump assembly and oil pressure 
filter and replacing pre-modification parts with parts eligible for 
installation.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule 
because the compliance time for the action is less than the time 
required for public comment. EASA made a determination of an unsafe 
condition warranting regulatory action and compliance within 25 flight 
hours or 30 days. Therefore, we find good cause that notice and 
opportunity for prior public comment are impracticable. In addition, 
for the reason stated above, we find that

[[Page 21170]]

good cause exists for making this amendment effective in less than 30 
days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this final rule. Send your comments to an address 
listed under the ADDRESSES section. Include the docket number FAA-2018-
0287 and Product Identifier 2018-NE-10-AD at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this final rule. We will 
consider all comments received by the closing date and may amend this 
final rule because of those comments.
    We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this final rule.

Costs of Compliance

    We estimate that this AD affects 32 engines installed on airplanes 
of U.S. registry.
    We estimate the following costs to comply with this AD:

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to engines, propellers, and 
associated appliances to the Manager, Engine and Propeller Standards 
Branch, Policy and Innovation Division.

Regulatory Findings

    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, 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.
