Federal Register / Vol. 74, No. 169 / Wednesday, September 2, 2009 / Rules and Regulations
State education agencies that administer
child nutrition programs and with
organizations representing State and
local inspection agencies. These
discussions provided FNS an
opportunity to inform State and local
officials about the new inspection
requirement and to hear their concerns.
FNS also issued an interim rule to
solicit pubic comments.
Nature of Concerns and Need To Issue
This Rule
The main concern of the State and
local program operators and inspection
agencies is the cost associated with the
increased inspection requirement. Some
schools now have to pay or pay more for
the food safety inspections, and some
inspection agencies have limited staff to
handle the increased inspection load.
Although we are aware that compliance
with this requirement may still be
difficult in some areas, it is our
responsibility to implement these
mandatory statutory requirements
which are non-discretionary.
erowe on DSK5CLS3C1PROD with RULES
Extent to Which FNS Meets Those
Concerns
FNS has considered the comments
and suggestions offered by State and
local program operators, inspection
agencies and others, but we are unable
to make changes that are inconsistent
with the inspection requirement as
prescribed by the law. We will continue
to provide information and guidance to
those affected by this rule and to
encourage regulatory agencies to help
schools comply with this rule.
To minimize the impact of this rule,
FNS will continue to apply the
inspections requirement to preparation
and service sites rather than to
individual meal programs (NSLP and
SBP). FNS will allow inspections
performed under the Summer Food
Service Program and the Child and
Adult Care Food Program to count
toward this requirement if all the meal
programs use the same food service
facility.
Executive Order 12988
This rule has been reviewed under
Executive Order 12988, Civil Justice
Reform. This rule has a preemptive
effect with respect to any State or local
laws, regulations or policies which
conflict with its provisions or which
would otherwise impede its full
implementation. This rule is not
intended to have retroactive effect
unless so specified in the Effective Date
paragraph of this rule. Prior to any
judicial challenge to the provisions of
this rule or the application of its
provisions, all applicable administrative

procedures under section 210.18(q)
must be exhausted.
Civil Rights Impact Analysis
FNS has reviewed this final rule in
accordance with the Department
Regulation 4300–4, ‘‘Civil Rights Impact
Analysis,’’ to identify any major civil
rights impacts the rule might have on
children on the basis of race, color,
national origin, sex, age or disability.
After a careful review of the rule’s intent
and provisions, FNS has determined
that it does not affect the participation
of protected individuals in the National
School Lunch and School Breakfast
Programs.
Paperwork Reduction Act
The Paperwork Reduction Act of 1995
(44 U.S.C. Chap. 35, see 5 CFR part
1320) requires that OMB approve all
collections of information by a Federal
agency from the public before they can
be implemented. Respondents are not
required to respond to any collection of
information unless it displays a current
valid OMB control number. The
information collection requirements
associated with this action were
approved by the Office of Management
and Budget on May 29, 2009 under
OMB Control Number 0584–0006,
Expiration date May 31, 2012, which
contains the information collection
activities in the NSLP.
The entire School Food Safety
Inspection data collection burden for
both NSLP and SBP operators is
contained only in OMB Control Number
0584–0006 and not the SBP (OMB
Control Number 2, Expiration May 31,
2012) because the NSLP is a larger
nutrition program and food safety
inspections conducted in the NSLP
count toward the inspection
requirement in both meal programs. The
burden hours estimate provided in the
notice of proposed information
collection published on May 12, 2005
(70 FR 25014) has increased from
9,483,231 to 9,558,282 due to an
adjustment in the number of School
Food Authorities and schools
participating in the NSLP and SBP.
E-Government Act Compliance
FNS is committed to compliance with
the E-Government Act (E-Gov), 2002
which requires Government agencies to
provide the public the option of
submitting information or transacting
business electronically to the maximum
extent possible. FNS has requested that
State agencies submit electronically the
inspections report required by this rule.

SUPPLEMENTARY INFORMATION:
erowe on DSK5CLS3C1PROD with RULES
Authority for This Rulemaking
The FAA’s authority to issue rules on
aviation safety is found in Title 49 of the
United States Code. 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.
This rulemaking is promulgated
under the authority described in subtitle
VII, part A, subpart III, section 44701,
‘‘General requirements.’’ Under that
section, the FAA is charged 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, including
minimum safety standards for aircraft
engines. This regulation is within the
scope of that authority because it
updates the existing regulations for
aircraft engine standards overtorque
limits.
Background
Part 33 of Title 14, Code of Federal
Regulations (14 CFR part 33) prescribes
airworthiness standards for original and
amended type certificates for aircraft
engines. The European Aviation Safety
Agency (EASA) Certification
Specification—Engines (CS–E)
prescribes corresponding airworthiness
standards to certify aircraft engines in
Europe. While part 33 and the CS–E are
similar, they differ in several respects.
These differences result in added costs,
delays, and time required for
certification. In addition, U.S. aircraft
engine manufacturers face additional
costs when seeking certification of their
engine designs by the EASA for export.
CS–E contains specific standards for
approval of maximum overtorque limits.
Currently, part 33 does not contain
explicit standards for a maximum
engine overtorque limit. Engine
manufacturers apply for and obtain FAA
VerDate Nov<24>2008
15:07 Sep 01, 2009
Jkt 217001
approvals of maximum overtorque
limits based on the results of
certification engine tests and analysis
that do not directly address
considerations for maximum overtorque
limits.
The FAA tasked the Aviation
Rulemaking Advisory Committee
(ARAC), through its Engine
Harmonization Working Group (EHWG),
to provide advice and recommendations
on proposed standards for engine
overtorque. We published that tasking
in the Federal Register on October 20,
1998 (63 FR 56059). This final rule is
based on ARAC’s recommendations.
Summary of the NPRM
The FAA published a notice of
proposed rulemaking (NPRM) on March
26, 2008 (73 FR 15955). The proposal
adds a new definition to § 1.1, changes
to § 33.7, and introduces § 33.84. These
proposed changes would add a new
engine overtorque test, amend engine
ratings and operating limitations, and
define maximum engine overtorque for
certain turbopropeller and turboshaft
engines. The proposal would harmonize
U.S. and European standards for
approving engine overtorque transients
for turbopropeller and turboshaft
engines with free power turbines. The
comment period closed June 24, 2008.
Summary of Comments
The FAA received four comment
letters, one from a British engine
manufacturer (Rolls-Royce Corporation),
one from a foreign regulatory authority
(Transport Canada), and two from law
students at the University of Central
Missouri. All four comment letters
support the general intent of the
proposed rule. However, Transport
Canada raised specific concerns that
were addressed by clarifying revisions
to proposed §§ 33.7 and 33.84. A
detailed discussion of changes to the
final rule is presented below.
Discussion of the Final Rule
The final rule establishes a standard
for applicants to use when applying for
and obtaining approval of a maximum
engine overtorque limit. This rule
harmonizes FAA and EASA standards
and simplifies airworthiness approvals
for the import and export of
turbopropeller and turboshaft engines
with free power turbines. The rule also
improves safety by stating clear
requirements for maximum engine
overtorque limits.
Below are specific comments from
Transport Canada and our responses to
them.
1. The approach proposed, to seek an
‘‘approval’’ for overtorque, is
PO 00000
Frm 00004
Fmt 4700
Sfmt 4700
inconsistent with the approach used for
‘‘overspeed’’ and ‘‘overtemperature’’.
Transport Canada suggested the
approach for ‘‘overtorque’’ be similar to
‘‘overspeed’’ and ‘‘overtemperature’’.
We do not agree. Overspeed and
overtemperature are transients which
are approved when they occur during
normal engine operation, e.g., a short
duration transient exceedance of a
rating (speed, temperature, or torque) as
the engine stabilizes at a new operating
condition following an acceleration. As
proposed in the NPRM, the ‘‘maximum
engine overtorque’’ is optional to the
applicant. This optional operating
condition is not an approved transient,
but an ‘‘over limit’’ condition which
may occur due to a failure. The
applicant can choose whether to declare
any maximum engine overtorque.
However, to ensure the regulation is
clear, we have revised proposed § 33.7
to clarify that engine ratings and
operating limitations include both the
existing transient engine overtorque and
the new maximum engine overtorque
‘‘over limit’’. We also revised
§ 33.87(a)(8) to clarify the requirement
applies to all transient functions,
including engine overtorque. This
makes clear that transient engine
overtorque is addressed in § 33.87(a)(8)
and maximum engine overtorque in
§ 33.84.
2. The definition of ‘‘Maximum
engine overtorque’’ in § 1.1 is not
necessary since part 33 does not have
similar definitions for ‘‘overspeed’’ or
‘‘overtemperature’’.
The FAA does not agree. Overspeed
and overtemperature in part 33 are
transient events and part of the normal
operation of the engine as defined in the
type design. Maximum engine
overtorque is an ‘‘over limit’’ condition
that could last up to 20 seconds and is
a result of some failure. A definition in
§ 1.1 is necessary as maximum engine
overtorque is unique in its application
to turbopropeller and turboshaft
engines. Explanation is required to
define the context in which this
condition would apply and specific
exclusions related to it. Transient
overspeed and overtemperature are
general and well understood terms used
widely throughout part 33. No
maintenance action is necessary by the
aircraft operator provided the cause of
the failure is corrected, and the engine
meets the new maximum engine
overtorque limit requirement.
3. The proposed § 33.84 overtorque
test requirement should be independent
from the § 33.87 endurance test
requirement. Transport Canada also
proposed the overtorque test
requirement be at least 10% torque over
E:\FR\FM\02SER1.SGM
02SER1
Federal Register / Vol. 74, No. 169 / Wednesday, September 2, 2009 / Rules and Regulations
the highest torque limit for any rating
longer than 2 minutes.
We agree, in part, that the overtorque
and endurance tests may be performed
separately. However, we did not set an
overtorque limit because it is the
applicant’s responsibility to decide the
maximum engine overtorque for the
engine.
Lastly, we made a clarifying change to
wording in the first sentence of
§ 33.84(b)(4). This change did not alter
our intent or the meaning of the
proposed regulation.
Paperwork Reduction Act
The Paperwork Reduction Act of 1995
(44 U.S.C. 3507(d)) requires the FAA to
consider the impact of paperwork and
other information collection burdens
imposed on the public. We have
determined that there are no new
information collection requirements
associated with this amendment.
International Compatibility
In keeping with U.S. obligations
under the Convention on International
Civil Aviation, it is FAA policy to
comply with International Civil
Aviation Organization (ICAO) Standards
and Recommended Practices to the
maximum extent practicable. The FAA
has reviewed the corresponding ICAO
Standards and Recommended Practices
and determined there are no differences
with these regulations.
Regulatory Evaluation Summary
erowe on DSK5CLS3C1PROD with RULES
Regulatory Evaluation, Regulatory
Flexibility Determination, International
Trade Assessment, and Unfunded
Mandates Assessment
Changes to Federal regulations must
undergo several economic analyses.
First, Executive Order 12866 directs that
each Federal agency shall propose or
adopt a regulation only upon a reasoned
determination that the benefits of the
intended regulation justify its costs.
Second, the Regulatory Flexibility Act
of 1980 (Pub. L. 96–354) requires
agencies to analyze the economic
impact of regulatory changes on small
entities. Third, the Trade Agreements
Act (Pub. L. 96–39) prohibits agencies
from setting standards that create
unnecessary obstacles to the foreign
commerce of the United States. In
developing U.S. standards, this Trade
Act requires agencies to consider
international standards and, where
appropriate, that they be the basis of
U.S. standards. Fourth, the Unfunded
Mandates Reform Act of 1995 (Pub. L.
104–4) requires agencies to prepare a
written assessment of the costs, benefits,
and other effects of proposed or final
VerDate Nov<24>2008
15:07 Sep 01, 2009
Jkt 217001
rules that include a Federal mandate
likely to result in the expenditure by
State, local, or tribal governments, in the
aggregate, or by the private sector, of
$100 million or more annually (adjusted
for inflation with base year of 1995).
This portion of the preamble
summarizes the FAA’s analysis of the
economic impacts of this final rule.
Department of Transportation Order
DOT 2100.5 prescribes policies and
procedures for simplification, analysis,
and review of regulations. If the
expected cost impact is so minimal that
a proposed or final rule does not
warrant a full evaluation, this order
permits that a statement to that effect
and the basis for it be included in the
preamble if a full regulatory evaluation
of the cost and benefits is not prepared.
Such a determination has been made for
this final rule. The reasoning for this
determination follows:
This final rule coordinates FAA
engine requirements with existing
EASA engine requirements that
manufacturers must currently meet in
order for their engines to be used in
European operations. Consequently, this
rule will allow engine manufacturers to
meet one requirement rather than
separate requirements for FAA/EASA
certification. There were no public
comments on the economic impact of
the NPRM. As a result, the expected
outcome will be a minimal impact with
positive net benefits.
A regulatory evaluation was not
prepared. This final rule incorporates
existing certification practices, while
maintaining the existing level of safety.
The benefits of this rule justify the costs
and the existing level of safety will be
preserved. The Office of Management
and Budget has determined that this
final rule is a ‘‘significant regulatory
action’’ because it harmonizes U.S.
aviation standards with those of other
civil aviation authorities.
Regulatory Flexibility Determination
The Regulatory Flexibility Act of 1980
(Pub. L. 96–354) (RFA) establishes ‘‘as a
principle of regulatory issuance that
agencies shall endeavor, consistent with
the objectives of the rule and of
applicable statutes, to fit regulatory and
informational requirements to the scale
of the businesses, organizations, and
governmental jurisdictions subject to
regulation. To achieve this principle,
agencies are required to solicit and
consider flexible regulatory proposals
and to explain the rationale for their
actions to assure that such proposals are
given serious consideration.’’ The RFA
covers a wide-range of small entities,
including small businesses, not-for-
PO 00000
Frm 00005
Fmt 4700
Sfmt 4700
45309
profit organizations, and small
governmental jurisdictions.
Agencies must perform a review to
determine whether a rule will have a
significant economic impact on a
substantial number of small entities. If
the agency determines that it will, the
agency must prepare a regulatory
flexibility analysis as described in the
RFA. However, if an agency determines
that a rule is not expected to have a
significant economic impact on a
substantial number of small entities,
section 605(b) of the RFA provides that
the head of the agency may so certify
and a regulatory flexibility analysis is
not required. The certification must
include a statement providing the
factual basis for this determination, and
the reasoning should be clear.
We stated in the initial Regulatory
Flexibility Analysis that we believed the
rule would be a cost-relieving rule as it
harmonizes with the EASA aviation
regulations. We received no comments
to the contrary.
Therefore, as the FAA Administrator,
I certify that this rule will not have a
significant economic impact on a
substantial number of small entities.
International Trade Analysis
The Trade Agreements Act of 1979
(Pub. L. 96–39), as amended by the
Uruguay Round Agreements Act (Pub.
L. 103–465), prohibits Federal agencies
from establishing any standards or
engaging in related activities that create
unnecessary obstacles to the foreign
commerce of the United States.
Pursuant to these Acts, the
establishment of standards is not
considered an unnecessary obstacle to
the foreign commerce of the United
States, so long as the standards have a
legitimate domestic objective, such as
the protection of safety, and do not
operate in a manner that excludes
imports that meet this objective. The
statute also requires consideration of
international standards and, where
appropriate, that they be the basis for
U.S. standards. This rule uses
international standards as the basis for
regulation and thus is consistent with
the Trade Agreements Act.
Unfunded Mandates Assessment
Title II of the Unfunded Mandates
Reform Act of 1995 (Pub. L. 104–4)
requires each Federal agency to prepare
a written statement assessing the effects
of any Federal mandate in a proposed or
final agency rule that may result in an
expenditure of $100 million or more (in
1995 dollars) in any one year by State,
local, and tribal governments, in the
aggregate, or by the private sector; such
a mandate is deemed to be a ‘‘significant
E:\FR\FM\02SER1.SGM
02SER1
45310
Federal Register / Vol. 74, No. 169 / Wednesday, September 2, 2009 / Rules and Regulations
regulatory action.’’ The FAA currently
uses an inflation-adjusted value of
$136.1 million in lieu of $100 million.
This final rule does not contain such a
mandate, therefore, the requirements of
Title II of the Act do not apply.
Executive Order 13132, Federalism
The FAA has analyzed this proposed
rule under the principles and criteria of
Executive Order 13132, Federalism. We
determined that this action will not
have a substantial direct effect on the
States, on the relationship between the
Federal Government and the States, or
on the distribution of power and
responsibilities among the various
levels of government, and, therefore,
does not have federalism implications.
Environmental Analysis
FAA Order 1050.1E identifies FAA
actions that are categorically excluded
from preparation of an environmental
assessment or environmental impact
statement under the National
Environmental Policy Act in the
absence of extraordinary circumstances.
The FAA has determined this
rulemaking action qualifies for the
categorical exclusion identified in
Chapter 3, paragraph 312d, and involves
no extraordinary circumstances.
erowe on DSK5CLS3C1PROD with RULES
Regulations That Significantly Affect
Energy Supply, Distribution, or Use
The FAA has analyzed this final rule
under Executive Order 13211, Actions
Concerning Regulations That
Significantly Affect Energy Supply,
Distribution, or Use (May 18, 2001). We
have determined that it is not a
‘‘significant energy action’’ under the
executive order, and is not likely to
have a significant adverse effect on the
supply, distribution, or use of energy.

(a) If approval of a maximum engine
overtorque is sought for an engine
incorporating a free power turbine,
compliance with this section must be
demonstrated by testing.
(1) The test may be run as part of the
endurance test requirement of § 33.87.
Alternatively, tests may be performed

and (a)(2).
(b) The test conditions must be as
follows:
(1) A total of 15 minutes run at the
maximum engine overtorque to be
approved. This may be done in separate
runs, each being of at least 21⁄2 minutes
duration.
(2) A power turbine rotational speed
equal to the highest speed at which the
maximum overtorque can occur in
service. The test speed may not be more
than the limit speed of take-off or OEI
ratings longer than 2 minutes.
(3) For engines incorporating a
reduction gearbox, a gearbox oil
temperature equal to the maximum
temperature when the maximum engine
overtorque could occur in service; and

SUPPLEMENTARY INFORMATION:
Authority for This Rulemaking
The FAA's authority to issue rules on aviation safety is found in
Title 49 of the United States Code. 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.
This rulemaking is promulgated under the authority described in
subtitle VII, part A, subpart III, section 44701, ``General
requirements.'' Under that section, the FAA is charged 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, including minimum safety
standards for aircraft engines. This regulation is within the scope of
that authority because it updates the existing regulations for aircraft
engine standards overtorque limits.
Background
Part 33 of Title 14, Code of Federal Regulations (14 CFR part 33)
prescribes airworthiness standards for original and amended type
certificates for aircraft engines. The European Aviation Safety Agency
(EASA) Certification Specification--Engines (CS-E) prescribes
corresponding airworthiness standards to certify aircraft engines in
Europe. While part 33 and the CS-E are similar, they differ in several
respects. These differences result in added costs, delays, and time
required for certification. In addition, U.S. aircraft engine
manufacturers face additional costs when seeking certification of their
engine designs by the EASA for export. CS-E contains specific standards
for approval of maximum overtorque limits.
Currently, part 33 does not contain explicit standards for a
maximum engine overtorque limit. Engine manufacturers apply for and
obtain FAA approvals of maximum overtorque limits based on the results
of certification engine tests and analysis that do not directly address
considerations for maximum overtorque limits.
The FAA tasked the Aviation Rulemaking Advisory Committee (ARAC),
through its Engine Harmonization Working Group (EHWG), to provide
advice and recommendations on proposed standards for engine overtorque.
We published that tasking in the Federal Register on October 20, 1998
(63 FR 56059). This final rule is based on ARAC's recommendations.
Summary of the NPRM
The FAA published a notice of proposed rulemaking (NPRM) on March
26, 2008 (73 FR 15955). The proposal adds a new definition to Sec.
1.1, changes to Sec. 33.7, and introduces Sec. 33.84. These proposed
changes would add a new engine overtorque test, amend engine ratings
and operating limitations, and define maximum engine overtorque for
certain turbopropeller and turboshaft engines. The proposal would
harmonize U.S. and European standards for approving engine overtorque
transients for turbopropeller and turboshaft engines with free power
turbines. The comment period closed June 24, 2008.
Summary of Comments
The FAA received four comment letters, one from a British engine
manufacturer (Rolls-Royce Corporation), one from a foreign regulatory
authority (Transport Canada), and two from law students at the
University of Central Missouri. All four comment letters support the
general intent of the proposed rule. However, Transport Canada raised
specific concerns that were addressed by clarifying revisions to
proposed Sec. Sec. 33.7 and 33.84. A detailed discussion of changes to
the final rule is presented below.
Discussion of the Final Rule
The final rule establishes a standard for applicants to use when
applying for and obtaining approval of a maximum engine overtorque
limit. This rule harmonizes FAA and EASA standards and simplifies
airworthiness approvals for the import and export of turbopropeller and
turboshaft engines with free power turbines. The rule also improves
safety by stating clear requirements for maximum engine overtorque
limits.
Below are specific comments from Transport Canada and our responses
to them.
1. The approach proposed, to seek an ``approval'' for overtorque,
is inconsistent with the approach used for ``overspeed'' and
``overtemperature''. Transport Canada suggested the approach for
``overtorque'' be similar to ``overspeed'' and ``overtemperature''.
We do not agree. Overspeed and overtemperature are transients which
are approved when they occur during normal engine operation, e.g., a
short duration transient exceedance of a rating (speed, temperature, or
torque) as the engine stabilizes at a new operating condition following
an acceleration. As proposed in the NPRM, the ``maximum engine
overtorque'' is optional to the applicant. This optional operating
condition is not an approved transient, but an ``over limit'' condition
which may occur due to a failure. The applicant can choose whether to
declare any maximum engine overtorque. However, to ensure the
regulation is clear, we have revised proposed Sec. 33.7 to clarify
that engine ratings and operating limitations include both the existing
transient engine overtorque and the new maximum engine overtorque
``over limit''. We also revised Sec. 33.87(a)(8) to clarify the
requirement applies to all transient functions, including engine
overtorque. This makes clear that transient engine overtorque is
addressed in Sec. 33.87(a)(8) and maximum engine overtorque in Sec.
33.84.
2. The definition of ``Maximum engine overtorque'' in Sec. 1.1 is
not necessary since part 33 does not have similar definitions for
``overspeed'' or ``overtemperature''.
The FAA does not agree. Overspeed and overtemperature in part 33
are transient events and part of the normal operation of the engine as
defined in the type design. Maximum engine overtorque is an ``over
limit'' condition that could last up to 20 seconds and is a result of
some failure. A definition in Sec. 1.1 is necessary as maximum engine
overtorque is unique in its application to turbopropeller and
turboshaft engines. Explanation is required to define the context in
which this condition would apply and specific exclusions related to it.
Transient overspeed and overtemperature are general and well understood
terms used widely throughout part 33. No maintenance action is
necessary by the aircraft operator provided the cause of the failure is
corrected, and the engine meets the new maximum engine overtorque limit
requirement.
3. The proposed Sec. 33.84 overtorque test requirement should be
independent from the Sec. 33.87 endurance test requirement. Transport
Canada also proposed the overtorque test requirement be at least 10%
torque over
[[Page 45309]]
the highest torque limit for any rating longer than 2 minutes.
We agree, in part, that the overtorque and endurance tests may be
performed separately. However, we did not set an overtorque limit
because it is the applicant's responsibility to decide the maximum
engine overtorque for the engine.
Lastly, we made a clarifying change to wording in the first
sentence of Sec. 33.84(b)(4). This change did not alter our intent or
the meaning of the proposed regulation.
Paperwork Reduction Act
The Paperwork Reduction Act of 1995 (44 U.S.C. 3507(d)) requires
the FAA to consider the impact of paperwork and other information
collection burdens imposed on the public. We have determined that there
are no new information collection requirements associated with this
amendment.
International Compatibility
In keeping with U.S. obligations under the Convention on
International Civil Aviation, it is FAA policy to comply with
International Civil Aviation Organization (ICAO) Standards and
Recommended Practices to the maximum extent practicable. The FAA has
reviewed the corresponding ICAO Standards and Recommended Practices and
determined there are no differences with these regulations.
Regulatory Evaluation Summary
Regulatory Evaluation, Regulatory Flexibility Determination,
International Trade Assessment, and Unfunded Mandates Assessment
Changes to Federal regulations must undergo several economic
analyses. First, Executive Order 12866 directs that each Federal agency
shall propose or adopt a regulation only upon a reasoned determination
that the benefits of the intended regulation justify its costs. Second,
the Regulatory Flexibility Act of 1980 (Pub. L. 96-354) requires
agencies to analyze the economic impact of regulatory changes on small
entities. Third, the Trade Agreements Act (Pub. L. 96-39) prohibits
agencies from setting standards that create unnecessary obstacles to
the foreign commerce of the United States. In developing U.S.
standards, this Trade Act requires agencies to consider international
standards and, where appropriate, that they be the basis of U.S.
standards. Fourth, the Unfunded Mandates Reform Act of 1995 (Pub. L.
104-4) requires agencies to prepare a written assessment of the costs,
benefits, and other effects of proposed or final rules that include a
Federal mandate likely to result in the expenditure by State, local, or
tribal governments, in the aggregate, or by the private sector, of $100
million or more annually (adjusted for inflation with base year of
1995). This portion of the preamble summarizes the FAA's analysis of
the economic impacts of this final rule.
Department of Transportation Order DOT 2100.5 prescribes policies
and procedures for simplification, analysis, and review of regulations.
If the expected cost impact is so minimal that a proposed or final rule
does not warrant a full evaluation, this order permits that a statement
to that effect and the basis for it be included in the preamble if a
full regulatory evaluation of the cost and benefits is not prepared.
Such a determination has been made for this final rule. The reasoning
for this determination follows:
This final rule coordinates FAA engine requirements with existing
EASA engine requirements that manufacturers must currently meet in
order for their engines to be used in European operations.
Consequently, this rule will allow engine manufacturers to meet one
requirement rather than separate requirements for FAA/EASA
certification. There were no public comments on the economic impact of
the NPRM. As a result, the expected outcome will be a minimal impact
with positive net benefits.
A regulatory evaluation was not prepared. This final rule
incorporates existing certification practices, while maintaining the
existing level of safety. The benefits of this rule justify the costs
and the existing level of safety will be preserved. The Office of
Management and Budget has determined that this final rule is a
``significant regulatory action'' because it harmonizes U.S. aviation
standards with those of other civil aviation authorities.
Regulatory Flexibility Determination
The Regulatory Flexibility Act of 1980 (Pub. L. 96-354) (RFA)
establishes ``as a principle of regulatory issuance that agencies shall
endeavor, consistent with the objectives of the rule and of applicable
statutes, to fit regulatory and informational requirements to the scale
of the businesses, organizations, and governmental jurisdictions
subject to regulation. To achieve this principle, agencies are required
to solicit and consider flexible regulatory proposals and to explain
the rationale for their actions to assure that such proposals are given
serious consideration.'' The RFA covers a wide-range of small entities,
including small businesses, not-for-profit organizations, and small
governmental jurisdictions.
Agencies must perform a review to determine whether a rule will
have a significant economic impact on a substantial number of small
entities. If the agency determines that it will, the agency must
prepare a regulatory flexibility analysis as described in the RFA.
However, if an agency determines that a rule is not expected to have a
significant economic impact on a substantial number of small entities,
section 605(b) of the RFA provides that the head of the agency may so
certify and a regulatory flexibility analysis is not required. The
certification must include a statement providing the factual basis for
this determination, and the reasoning should be clear.
We stated in the initial Regulatory Flexibility Analysis that we
believed the rule would be a cost-relieving rule as it harmonizes with
the EASA aviation regulations. We received no comments to the contrary.
Therefore, as the FAA Administrator, I certify that this rule will
not have a significant economic impact on a substantial number of small
entities.
International Trade Analysis
The Trade Agreements Act of 1979 (Pub. L. 96-39), as amended by the
Uruguay Round Agreements Act (Pub. L. 103-465), prohibits Federal
agencies from establishing any standards or engaging in related
activities that create unnecessary obstacles to the foreign commerce of
the United States. Pursuant to these Acts, the establishment of
standards is not considered an unnecessary obstacle to the foreign
commerce of the United States, so long as the standards have a
legitimate domestic objective, such as the protection of safety, and do
not operate in a manner that excludes imports that meet this objective.
The statute also requires consideration of international standards and,
where appropriate, that they be the basis for U.S. standards. This rule
uses international standards as the basis for regulation and thus is
consistent with the Trade Agreements Act.
Unfunded Mandates Assessment
Title II of the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-
4) requires each Federal agency to prepare a written statement
assessing the effects of any Federal mandate in a proposed or final
agency rule that may result in an expenditure of $100 million or more
(in 1995 dollars) in any one year by State, local, and tribal
governments, in the aggregate, or by the private sector; such a mandate
is deemed to be a ``significant
[[Page 45310]]
regulatory action.'' The FAA currently uses an inflation-adjusted value
of $136.1 million in lieu of $100 million. This final rule does not
contain such a mandate, therefore, the requirements of Title II of the
Act do not apply.
Executive Order 13132, Federalism
The FAA has analyzed this proposed rule under the principles and
criteria of Executive Order 13132, Federalism. We determined that this
action will not have a substantial direct effect on the States, on the
relationship between the Federal Government and the States, or on the
distribution of power and responsibilities among the various levels of
government, and, therefore, does not have federalism implications.
Environmental Analysis
FAA Order 1050.1E identifies FAA actions that are categorically
excluded from preparation of an environmental assessment or
environmental impact statement under the National Environmental Policy
Act in the absence of extraordinary circumstances. The FAA has
determined this rulemaking action qualifies for the categorical
exclusion identified in Chapter 3, paragraph 312d, and involves no
extraordinary circumstances.
Regulations That Significantly Affect Energy Supply, Distribution, or
Use
The FAA has analyzed this final rule under Executive Order 13211,
Actions Concerning Regulations That Significantly Affect Energy Supply,
Distribution, or Use (May 18, 2001). We have determined that it is not
a ``significant energy action'' under the executive order, and is not
likely to have a significant adverse effect on the supply,
distribution, or use of energy.
