sensitivity analysis tools, as appropriate, to
evaluate the potential distribution of impacts
of candidate/trial standard levels among
different subgroups of consumers. The
Department will consider impacts on
significant segments of consumers in
determining standards levels. Where there
are significant negative impacts on
identifiable subgroups, DOE will consider the
efficacy of voluntary approaches as a means
to achieve potential energy savings.
(e) Payback period and first cost. (1) In the
assessment of consumer impacts of
standards, the Department will consider LifeCycle Cost, Payback Period, and Cost of
Conserved Energy to evaluate the savings in
operating expenses relative to increases in
purchase price. The Department also
performs sensitivity and scenario analyses
when appropriate. The results of these
analyses will be carried throughout the
analysis and the ensuing uncertainty
described.
(2) If, in the analysis of consumer impacts,
the Department determines that a candidate/
trial standard level would result in a
substantial increase in product/equipment
first costs to consumers or would not pay
back such additional first costs through
energy cost savings in less than three years,
Department will assess the likely impacts of
such a standard on low-income households,
product/equipment sales and fuel switching,
as appropriate.

15. Consideration of Non-Regulatory
Approaches
The Department recognizes that nonregulatory efforts by manufacturers, utilities,
and other interested parties can result in
substantial efficiency improvements. The
Department intends to consider the likely
effects of non-regulatory initiatives on
product/equipment energy use, consumer
utility and life-cycle costs, manufacturers,
competition, utilities, and the environment,
as well as the distribution of these impacts
among different regions, consumers,
manufacturers, and utilities. DOE will
attempt to base its assessment on the actual
impacts of such initiatives to date, but also
will consider information presented
regarding the impacts that any existing
initiative might have in the future. Such
information is likely to include a
demonstration of the strong commitment of
manufacturers, distribution channels,
utilities, or others to such non-regulatory
efficiency improvements. This information
will be used in assessing the likely
incremental impacts of establishing or
revising standards, in assessing—where
possible—appropriate compliance dates for
new or revised standards, and in considering
DOE support of non-regulatory initiatives.
16. Cross-Cutting Analytical Assumptions
In selecting values for certain cross-cutting
analytical assumptions, DOE expects to
continue relying upon the following sources
and general principles:
(a) Underlying economic assumptions. The
appliance standards analyses will generally
use the same economic growth and
development assumptions that underlie the
most current Annual Energy Outlook (AEO)
VerDate Sep<11>2014
16:12 Apr 09, 2021
Jkt 253001
published by the Energy Information
Administration (EIA).
(b) Analytic time length. The appliance
standards analyses will use two time
lengths—30 years and another time length
that is specific to the standard being
considered such as the useful lifetime of the
product under consideration. As a sensitivity
case, the analyses will also use a 9-year
regulatory timeline in analyzing the effects of
the standard.
(c) Energy price and demand trends.
Analyses of the likely impact of appliance
standards on typical users will generally
adopt the mid-range energy price and
demand scenario of the EIA’s most current
AEO. The sensitivity of such estimated
impacts to possible variations in future
energy prices are likely to be examined using
the EIA’s high and low energy price
scenarios.
(d) Product/equipment-specific energyefficiency trends, without updated standards.
Product/equipment-specific energy-efficiency
trends will be based on a combination of the
efficiency trends forecast by the EIA’s
residential and commercial demand model of
the National Energy Modeling System
(NEMS) and product-specific assessments by
DOE and its contractors with input from
interested parties.
(e) Price forecasting. DOE will endeavor to
use robust price forecasting techniques in
projecting future prices of products.
(f) Private Discount rates. For residential
and commercial consumers, ranges of three
different real discount rates will be used. For
residential consumers, the mid-range
discount rate will represent DOE’s
approximation of the average financing cost
(or opportunity costs of reduced savings)
experienced by typical consumers.
Sensitivity analyses will be performed using
discount rates reflecting the costs more likely
to be experienced by residential consumers
with little or no savings and credit card
financing and consumers with substantial
savings. For commercial users, a mid-range
discount rate reflecting DOE’s approximation
of the average real rate of return on
commercial investment will be used, with
sensitivity analyses being performed using
values indicative of the range of real rates of
return likely to be experienced by typical
commercial businesses. For national net
present value calculations, DOE would use
the Administration’s approximation of the
average real rate of return on private
investment in the U.S. economy. For
manufacturer impacts, DOE typically uses a
range of real discount rates which are
representative of the real rates of return
experienced by typical U.S. manufacturers
affected by the program.
(g) Social Discount Rates. Social discount
rates as specified in OMB Circular A–4 will
be used in assessing social effects such as
costs and benefits.
(h) Environmental impacts. (1) DOE
calculates emission reductions of carbon
dioxide, sulfur dioxide, nitrogen oxides,
methane, nitrous oxides, and mercury likely
to be avoided by candidate/trial standard
levels based on an emissions analysis that
includes the two components described in
paragraphs (h)(2) and (3) of this section.
PO 00000
Frm 00021
Fmt 4702
Sfmt 4702
18921
(2) The first component estimates the effect
of potential candidate/trial standard levels on
power sector and site combustion emissions
of carbon dioxide, nitrogen oxides, sulfur
dioxide, mercury, methane, and nitrous
oxide. DOE develops the power sector
emissions analysis using a methodology
based on DOE’s latest Annual Energy
Outlook. For site combustion of natural gas
or petroleum fuels, the combustion emissions
of carbon dioxide and nitrogen oxides are
estimated using emission intensity factors
from the Environmental Protection Agency.
(3) The second component of DOE’s
emissions analysis estimates the effect of
potential candidate/trial standard levels on
emissions of carbon dioxide, nitrogen oxides,
sulfur dioxide, mercury, methane, and
nitrous oxide due to ‘‘upstream activities’’ in
the fuel production chain. These upstream
activities include the emissions related to
extracting, processing, and transporting fuels
to the site of combustion as detailed in DOE’s
Fuel-Fuel-Cycle Statement of Policy (76 FR
51281 (August 18, 2011)). DOE will consider
the effects of the candidate/trial standard
levels on these emissions after assessing the
seven factors required to demonstrate
economic justification under EPCA.
Consistent with Executive Order 13783,
dated March 28, 2017, when monetizing the
value of changes in reductions in CO2 and
nitrous oxides emissions resulting from its
energy conservation standards regulations,
including with respect to the consideration of
domestic versus international impacts and
the consideration of appropriate discount
rates, DOE ensures, to the extent permitted
by law, that any such estimates are consistent
with the guidance contained in OMB Circular
A–4 of September 17, 2003 (Regulatory
Analysis).

Background
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued TCCA AD CF–
2020–33, dated September 29, 2020
(also referred to after this as the
Mandatory Continuing Airworthiness
Information, or the MCAI), to correct an
unsafe condition for certain Bombardier,
Inc., Model BD–100–1A10 airplanes.
You may examine the MCAI in the AD

Sfmt 4702
This proposed AD was prompted by
a report that certain airplanes have
navigation units with outdated MagVar
tables. The FAA is proposing this AD to
address outdated MagVar tables inside
navigation systems, which can affect the
performance of the navigation systems
and result in the presentation of
misleading magnetic heading references
on the primary flight displays (PFDs)
and multi-function displays (MFDs),
positioning the airplane outside of the
terrain and obstacle protection provided
by instrument flight procedures and
flight route designs, and can lead to
significantly inaccurate heading, course,
and bearing calculations. See the MCAI
for additional background information.

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.
The FAA is 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.

Background
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2020-33, dated September
29, 2020 (also referred to after this as the Mandatory Continuing
Airworthiness Information, or the MCAI), to correct an unsafe condition
for certain Bombardier, Inc., Model BD-100-1A10 airplanes. You may
examine the MCAI in the AD docket at https://www.regulations.gov by
searching for and locating Docket No. FAA-2021-0272.
This proposed AD was prompted by a report that certain airplanes
have navigation units with outdated MagVar tables. The FAA is proposing
this AD to address outdated MagVar tables inside navigation systems,
which can affect the performance of the navigation systems and result
in the presentation of misleading magnetic heading references on the
primary flight displays (PFDs) and multi-function displays (MFDs),
positioning the airplane outside of the terrain and obstacle protection
provided by instrument flight procedures and flight route designs, and
can lead to significantly inaccurate heading, course, and bearing
calculations. See the MCAI for additional background information.
Related Service Information Under 1 CFR Part 51
Bombardier has issued the following service information. This
service information describes procedures for revising the existing AFM
to update the FMS limitations. These documents are distinct since they
apply to different airplane configurations.
Flight Management System (FMS) limitation in Section 02-
04--Systems Limitations, of Chapter 02--Limitations, of the Challenger
300 Airplane Flight Manual (Imperial Version), Publication No. CSP 100-
1, Revision 58, dated January 15, 2020. (For obtaining the FMS
limitation for Bombardier Challenger 300 Airplane Flight Manual
(Imperial Version), Publication No. CSP 100-1, use Document
Identification No. CH 300 AFM-I.)
FMS limitation in Section 02-04--Systems Limitations, of
Chapter 02--Limitations, of the Challenger 300 Airplane Flight Manual
(Metric Version), Publication No. CSP 100-1 (Metric), Revision 58,
dated January 15, 2020. (For obtaining the FMS limitation for
Bombardier Challenger 300 Airplane Flight Manual (Metric Version),
Publication No. CSP 100-1 (Metric), use Document Identification No. CH
300 AFM-M.)
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 aviation authority of another
country, and is approved for operation in the United States. Pursuant
to the FAA's bilateral agreement with the State of Design Authority,
the FAA has been notified of the unsafe condition described in the MCAI
and service information referenced above. The FAA is proposing this AD
because the FAA
[[Page 18923]]
evaluated all the relevant information and determined the unsafe
condition described previously is likely to exist or develop on other
products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in the service information already described.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 318 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85............................. $0 $85 $27,030
----------------------------------------------------------------------------------------------------------------
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.
The FAA is 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.
Regulatory Findings
The FAA 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) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
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
