SUPPLEMENTARY INFORMATION: Discussion We received information concerning damage to the engine fan hub found during an engine shop visit of an IAE PW1100G-series turbofan engine. The damage is believed to be the result of the installation of the inlet cone without using alignment pins, which might lead to bolts impacting and damaging the engine fan hub. This condition, if not addressed, could result in uncontained PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 failure of the engine fan hub, damage to the engine, and damage to the airplane. We are issuing this AD to address the unsafe condition on these products. Related Service Information Under 1 CFR Part 51 We reviewed Pratt & Whitney (PW) Service Bulletin (SB) PW1000G–C–72– 00–0104–00A–930A–D, Issue No. 002, dated May 31, 2018. The SB describes procedures for performing a one-time visual inspection of the inlet cone mating face and counter weight flange on the engine fan hub assembly for surface damage. 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 We are issuing this AD because we evaluated all the relevant information 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 a one-time visual inspection of the engine fan hub for damage, and replacement of the engine fan hub if damage or defects are found that are outside of serviceable limits. Differences Between the AD and the Service Information PW SB PW1000G–C–72–00–0104– 00A–930A–D, Issue No. 002, dated May 31, 2018, only applies to PW1100G–JM engine models in service. This AD applies to all PW1100G–JM engine models certified under type certificate E00087EN. PW SB PW1000G–C–72–00– 0104–00A–930A–D also excludes from its applicability certain serial numbered engines. We have no way to determine if these engines have been inspected and are therefore including these engines in the applicability of this AD. Interim Action We consider this AD interim action. An investigation to determine the cause of the failure is on-going and we may consider additional rulemaking if final action is identified. E:\FR\FM\26JNR1.SGM 26JNR1 29666 Federal Register / Vol. 83, No. 123 / Tuesday, June 26, 2018 / Rules and Regulations 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 is less than the time required for public comment. In addition, all engine fan hubs must be inspected, and if needed, replaced before further flight. Therefore, we find good cause that notice and compliance for prior public comment are impracticable. In addition, for the reasons stated above, we find that 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–2018–0564 and Product Identifier 2018–NE–23–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 14 engines installed on airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Visual inspection ............................................. 2 work-hours × $85 per hour = $170 ............. sradovich on DSK3GMQ082PROD with RULES 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.

AGENCY: This amendment adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas. DATES: Effective Date: 0901 UTC, July 19, 2018.

SUMMARY: PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 29667 This amendment to part 95 of the Federal Aviation Regulations (14 CFR part 95) amends, suspends, or revokes IFR altitudes governing the operation of all aircraft in flight over a specified route or any portion of that route, as well as the changeover points (COPs) for Federal airways, jet routes, or direct routes as prescribed in part 95. SUPPLEMENTARY INFORMATION: The Rule The specified IFR altitudes, when used in conjunction with the prescribed changeover points for those routes, ensure navigation aid coverage that is adequate for safe flight operations and free of frequency interference. The reasons and circumstances that create the need for this amendment involve matters of flight safety and operational efficiency in the National Airspace System, are related to published aeronautical charts that are essential to the user, and provide for the safe and efficient use of the navigable airspace. In addition, those various reasons or circumstances require making this amendment effective before the next scheduled charting and publication date of the flight information to assure its timely availability to the user. The effective date of this amendment reflects those considerations. In view of the close and immediate relationship between these regulatory changes and safety in air commerce, I find that notice and public procedure before adopting this amendment are impracticable and contrary to the public interest and that good cause exists for making the amendment effective in less than 30 days. Conclusion The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore—(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); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. For the same reason, the FAA certifies that this amendment will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

SUPPLEMENTARY INFORMATION: 

Discussion

    We received information concerning damage to the engine fan hub 
found during an engine shop visit of an IAE PW1100G-series turbofan 
engine. The damage is believed to be the result of the installation of 
the inlet cone without using alignment pins, which might lead to bolts 
impacting and damaging the engine fan hub. This condition, if not 
addressed, could result in uncontained failure of the engine fan hub, 
damage to the engine, and damage to the airplane. We are issuing this 
AD to address the unsafe condition on these products.

Related Service Information Under 1 CFR Part 51

    We reviewed Pratt & Whitney (PW) Service Bulletin (SB) PW1000G-C-
72-00-0104-00A-930A-D, Issue No. 002, dated May 31, 2018. The SB 
describes procedures for performing a one-time visual inspection of the 
inlet cone mating face and counter weight flange on the engine fan hub 
assembly for surface damage. 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

    We are issuing this AD because we evaluated all the relevant 
information 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 a one-time visual inspection of the engine fan hub 
for damage, and replacement of the engine fan hub if damage or defects 
are found that are outside of serviceable limits.

Differences Between the AD and the Service Information

    PW SB PW1000G-C-72-00-0104-00A-930A-D, Issue No. 002, dated May 31, 
2018, only applies to PW1100G-JM engine models in service. This AD 
applies to all PW1100G-JM engine models certified under type 
certificate E00087EN. PW SB PW1000G-C-72-00-0104-00A-930A-D also 
excludes from its applicability certain serial numbered engines. We 
have no way to determine if these engines have been inspected and are 
therefore including these engines in the applicability of this AD.

Interim Action

    We consider this AD interim action. An investigation to determine 
the cause of the failure is on-going and we may consider additional 
rulemaking if final action is identified.

[[Page 29666]]

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 is less than the time required for public 
comment. In addition, all engine fan hubs must be inspected, and if 
needed, replaced before further flight. Therefore, we find good cause 
that notice and compliance for prior public comment are impracticable. 
In addition, for the reasons stated above, we find that 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-
0564 and Product Identifier 2018-NE-23-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 14 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 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, 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.
