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.

RIN 2120–AA64
Airworthiness Directives; International
Aero Engines (IAE) Turbofan Engines
Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
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.
DATES: We must receive comments on
this proposed AD by August 13, 2018.

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

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 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.

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

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.

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-

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 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 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
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Replace HPC front hub................. 0 work-hours x $85 per $11,600 $11,600 $185,600
hour = $0.
----------------------------------------------------------------------------------------------------------------
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
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.
