SUPPLEMENTARY INFORMATION: Discussion We received information concerning an uncontained engine fan hub failure that occurred on an EA GP7200-series turbofan engine. AD 2017–23–03 (82 FR 51979, November 9, 2017), requires visual inspections of all engine fan hubs for damage. This AD requires additional visual inspections of the EA GP7200series engine fan hub beyond those required by AD 2017–23–03. This AD also requires an ECI that was not required by AD 2017–23–03. This condition, if not addressed, could result in an 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 EA Alert Service Bulletin (ASB) EAGP7–A72–389, Revision No. 2, dated April 17, 2018. The ASB describes procedures for ECI and visual inspection of the GP7270, GP7272, and GP7277 engine fan hub. 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 ECI of the GP7270, GP7272, and GP7277 engine fan hub blade slot bottom and blade slot front edge for cracks, a visual inspection of the engine fan hub for damage, and removal of the engine fan hub if damage or defects are found that are outside of serviceable limits. 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. 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 the adoption of this rule because the compliance time for the required action is shorter than the time necessary for the public to comment and for us to publish the final rule. 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 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–2018–0501 and Product Identifier 2018–NE–19–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 http:// 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 0 engines installed on airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost ECI and visual inspection ............................... 14 work-hours × $85 per hour = $1190 ......... 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. VerDate Sep<11>2014 15:57 Jun 14, 2018 Jkt 244001 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 PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 Cost per product Parts cost $0 $1190 Cost on U.S. operators $0 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 E:\FR\FM\15JNR1.SGM 15JNR1 Federal Register / Vol. 83, No. 116 / Friday, June 15, 2018 / Rules and Regulations 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. of Engine Alliance (EA) Alert Service Bulletin (ASB) EAGP7–A72–389, Revision No. 2, dated April 17, 2018.

SUPPLEMENTARY INFORMATION:

Discussion

    We received information concerning an uncontained engine fan hub 
failure that occurred on an EA GP7200-series turbofan engine. AD 2017-
23-03 (82 FR 51979, November 9, 2017), requires visual inspections of 
all engine fan hubs for damage. This AD requires additional visual 
inspections of the EA GP7200-series engine fan hub beyond those 
required by AD 2017-23-03. This AD also requires an ECI that was not 
required by AD 2017-23-03. This condition, if not addressed, could 
result in an 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 EA Alert Service Bulletin (ASB) EAGP7-A72-389, Revision 
No. 2, dated April 17, 2018. The ASB describes procedures for ECI and 
visual inspection of the GP7270, GP7272, and GP7277 engine fan hub. 
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 ECI of the GP7270, GP7272, and GP7277 
engine fan hub blade slot bottom and blade slot front edge for cracks, 
a visual inspection of the engine fan hub for damage, and removal of 
the engine fan hub if damage or defects are found that are outside of 
serviceable limits.

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.

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 the adoption of this rule 
because the compliance time for the required action is shorter than the 
time necessary for the public to comment and for us to publish the 
final rule. 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 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-
0501 and Product Identifier 2018-NE-19-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 http://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 0 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

[[Page 27893]]

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.
