Email: Celia.Sher@ hq.doe.gov; (202) 287–6122. On April 25, 2018, the U.S. Department of Energy (DOE) published a petition from AHAM requesting that DOE reconsider its final rule on Test Procedures for Cooking Products, Docket No. EERE–2012–BT– TP–0013, RIN 1904–AC71, 81 FR 91418 (Dec. 16, 2016) (Final Rule). In the petition, AHAM requested that DOE undertake rulemaking to withdraw the cooking top test procedure, while maintaining the repeal of the oven test procedure that was part of the Final Rule. 83 FR 17944. The notice of petition provided for the written submission of comments by June 25, 2018. AHAM requested an extension of the public comment period to allow additional time for AHAM and its members to provide data responsive to DOE’s detailed inquiries regarding the petition. For the same reason, GE Appliances also requested an extension of the comment period. DOE has determined that an extension of the public comment period is appropriate to allow interested parties additional time to submit comments for DOE’s consideration. Thus, DOE is reopening the comment period by 21 days, until July 19, 2018. DOE will consider any comments received by midnight of July 19, 2018 to be timely submitted.

SUPPLEMENTARY INFORMATION: Comments Invited We invite you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2018–0431; Product Identifier 2018– NE–16–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this NPRM. We will consider all comments received by the closing date and may amend this NPRM 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 NPRM. Discussion We received a report that corrosion was found on HPC front hub, part number (P/N) 30G2401. The HPC front hub exhibited deposits that could not be removed using standard procedures and worsened over time. After further investigation, pitting corrosion was found below the painted surface. This condition, if not addressed, could result in uncontained HPC front hub release, damage to the engine, and damage to the airplane. Related Service Information We reviewed Section PW1000G–C– 05–10–00–02A–288A–D of the PW1100G–JM Series Airworthiness Limitations Manual, P/N 5316993, dated September 30, 2015. Section PW1000G– C–05–10–00–02A–288A–D provides guidance for an approved FAA method of mixed model cycles since new calculation. FAA’s Determination We are proposing 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. Proposed AD Requirements This proposed AD would require removing from service the HPC front hub, P/N 30G2401, and replacing it with a part eligible for installation. Costs of Compliance We estimate that this proposed AD affects 16 engines installed on airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Replace HPC front hub ................................... 0 work-hours × $85 per hour = $0 ................. amozie on DSK3GDR082PROD with PROPOSALS1 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. VerDate Sep<11>2014 16:20 Jun 27, 2018 Jkt 244001 Parts cost 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 We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 $11,600 Cost per product $11,600 Cost on U.S. operators $185,600 responsibilities among the various levels of government. For the reasons discussed above, I certify this proposed regulation: (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.

Airworthiness Directives; International Aero Engines (IAE) 
Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain International Aero Engines (IAE) PW1133G-JM, PW1133GA-JM, 
PW1130G-JM, PW1127G-JM, PW1127GA-JM, PW1127G1-JM, PW1124G-JM, PW1124G1-
JM, and PW1122G-JM turbofan engines with a certain high-pressure 
compressor (HPC) front hub installed. This proposed AD was prompted by 
corrosion found on the HPC front hub. This proposed AD would require 
replacing the HPC front hub with a part eligible for installation. We 
are proposing this AD to address the unsafe condition on these 
products.

SUPPLEMENTARY INFORMATION: 

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2018-0431; 
Product Identifier 2018-NE-16-AD'' at the beginning of your comments. 
We specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this NPRM. We will consider all 
comments received by the closing date and may amend this NPRM 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 NPRM.

Discussion

    We received a report that corrosion was found on HPC front hub, 
part number (P/N) 30G2401. The HPC front hub exhibited deposits that 
could not be removed using standard procedures and worsened over time. 
After further investigation, pitting corrosion was found below the 
painted surface. This condition, if not addressed, could result in 
uncontained HPC front hub release, damage to the engine, and damage to 
the airplane.

Related Service Information

    We reviewed Section PW1000G-C-05-10-00-02A-288A-D of the PW1100G-JM 
Series Airworthiness Limitations Manual, P/N 5316993, dated September 
30, 2015. Section PW1000G-C-05-10-00-02A-288A-D provides guidance for 
an approved FAA method of mixed model cycles since new calculation.

FAA's Determination

    We are proposing 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.

Proposed AD Requirements

    This proposed AD would require removing from service the HPC front 
hub, P/N 30G2401, and replacing it with a part eligible for 
installation.

Costs of Compliance

    We estimate that this proposed AD affects 16 engines installed on 
airplanes of U.S. registry.
    We estimate the following costs to comply with this proposed 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

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the DOT Regulatory Policies

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

International Aero Engines: Docket No. FAA-2018-0431; Product 
Identifier 2018-NE-16-AD.

(a) Comments Due Date

    We must receive comments by August 13, 2018.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to International Aero Engines (IAE) PW1133G-JM, 
PW1133GA-JM, PW1130G-JM, PW1127G-JM, PW1127GA-JM, PW1127G1-JM, 
PW1124G-JM, PW1124G1-JM, and PW1122G-JM turbofan engines with high-
pressure compressor (HPC) front hub, part number (P/N) 30G2401, 
installed.

(d) Subject

    Joint Aircraft System Component (JASC) Code 7230, Turbine Engine 
Compressor Section.

(e) Unsafe Condition

    This AD was prompted by corrosion found on the HPC front hub. We 
are issuing this AD to prevent cracking and failure of the HPC front 
hub. The unsafe condition, if not addressed, could result in 
uncontained HPC front hub release, damage to the engine, and damage 
to the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    Remove from service the HPC front hub, P/N 30G2401, within 120 
days after the effective date of this AD, or as follows, whichever 
occurs later, and replace with a part eligible for installation:
    (1) For PW1122G-JM, PW1124G1-JM, PW1124G-JM, PW1127G1-JM, 
PW1127GA-JM, and PW1127G-JM engines, remove the HPC front hub before 
exceeding 6,180 cycles since new (CSN) or within five years since 
the ship date listed in Table 1 to paragraph (g) of this AD, 
whichever occurs first.
    (2) For PW1130G-JM, PW1133GA-JM, and PW1133G-JM engines, remove 
the HPC front hub before exceeding 4,440 CSN or within four years 
since the ship date listed in Table 1 to paragraph (g) of this AD, 
whichever occurs first.
    (3) For engines operating as a mix of models listed in 
paragraphs (g)(1) and (2) of this AD, remove the HPC front hub using 
a CSN calculated by an approved FAA method or within four years 
since the ship date listed in Table 1 to paragraph (g) of this AD, 
whichever occurs first. You may find guidance for an approved FAA 
method of mixed model CSN calculation in Section PW1000G-C-05-10-00-
02A-288A-D of the PW1100G-JM Series Airworthiness Limitations 
Manual, P/N 5316993, dated September 30, 2015.
    (4) For any HPC front hub, P/N 30G2401, whose serial number is 
not listed in Table 1 to paragraph (g) of this AD, use October 21, 
2015, as the ship date.
