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, VerDate Sep<11>2014 16:05 Nov 26, 2018 Jkt 247001 Parts cost on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

SUMMARY: We are revising airworthiness directive (AD) 2018-20-03 for 
certain Hoffmann GmbH & Co. KG (Hoffmann) model HO-V 62 propellers. AD 
2018-20-03 required removal of the affected propeller blades and 
installation of modified propeller blades marked with a change letter 
``A'' or ``B'' suffix. This AD requires the removal and replacement of 
the affected propeller blades and installation of modified propeller 
blades marked with a change letter ``A'' or ``B'' suffix. This AD was 
prompted by a determination that the applicability and installation 
prohibition paragraphs of AD 2018-20-03 were incorrect. We 
inadvertently included all Hoffmann model HO-V 62 propeller blades that 
did not have a change letter ``A'' or ``B'' suffix added to the serial 
number (S/N) and marked on the blade in the applicability and 
installation prohibition paragraphs of AD 2018-20-03. Only Hoffmann 
model HO-V 62 propellers with certain S/Ns without a change letter 
``A'' or ``B'' suffix are affected. We are issuing this AD to address 
the unsafe condition on these products.

DATES: This AD is effective December 12, 2018.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued AD 2018-20-03, Amendment 39-19437 (83 FR 50821, October 
10, 2018), (``AD 2018-20-03''), for Hoffmann model HO-V 62 propellers. 
AD 2018-20-03 required removal of the affected propeller blades and 
installation of modified propeller blades marked with a change letter 
``A'' or ``B'' suffix. AD 2018-20-03 resulted from the failure of the 
propeller blade lag screws. We issued AD 2018-20-03 to prevent failure 
of the propeller.

Actions Since AD 2018-20-03 Was Issued

    Since we issued AD 2018-20-03, we determined that we inadvertently 
included all Hoffmann S/N model HO-V 62 propeller blades without a 
change letter ``A'' or ``B'' suffix in the applicability and 
installation prohibition paragraphs of this AD. This AD corrects the 
applicability and installation prohibition paragraphs to affect only 
Hoffmann model HO-V 62 propeller blades with S/N 1 to 6049, inclusive. 
We are issuing this AD to address the unsafe condition on these 
products.

Related Service Information

    We reviewed Hoffmann Propeller GmbH & Co. KG Service Bulletin (SB) 
E34 Rev. B, dated September 18, 2017. The SB describes the instructions 
for the removal and installation of the propeller blades. 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 the European Aviation Safety 
Agency (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 removal of the affected propeller blades and 
installation of modified propeller blades marked with a change letter 
``A'' or ``B'' suffix.

FAA's Justification and Determination of the Effective Date

    We are revising AD 2018-20-03 to correct the applicability and 
installation prohibition paragraphs, which were overly inclusive. We 
also reduced the compliance time in this AD to align more closely with 
the effective compliance time in AD 2018-20-03. We previously provided 
notice and an opportunity to comment on the substance of this 
rulemaking and received no comments. Therefore, we find that notice and 
opportunity for prior public comment are unnecessary and 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 we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. 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-2018-0975 and product identifier 
2018-NE-06-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 50 propellers installed on 
airplanes of U.S. registry.
    We estimate that 25 propellers will need to be replaced between 
overhaul and 25 propellers will need to be replaced at overhaul to 
comply with this AD:

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.
