1 Exposure scenario titles consist of release activity followed by exposure calculation abbreviation.

2 Release activities are from engineering report's Manufacturing (Mfg), Processing (Proc) and Use release activity labels. Multiple release activities are combined in one exposure scenario if their releases occur at same location.

3 Exposure calculations are Acute Dose Rate (ADR), Lifetime Average Daily Dose (LADD), and Probabilistic Dilution Model (PDM).  There may be one, two, or all three exposure calculations per exposure scenario. CC is the aquatic concentration of concern.

4 This column displays concentration values for the 7Q10 streamflow, which is defined as the average daily streamflow of the seven consecutive days of lowest flow within a ten year period.

RIN 2120-AA64

Airworthiness Directives; Airworthiness Directives; MHI RJ
Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.)
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100
& 440) airplanes. This proposed AD was prompted by a report of missing
insulation in the engine pylon area. This proposed AD would require,
for certain airplanes, inspecting the engine pylon structure for
discrepancies and repair if necessary. This proposed AD would also
require revising the existing maintenance or inspection program, as
applicable, to incorporate a new certification maintenance requirement
(CMR) task. The FAA is proposing this AD to address the unsafe
condition on these products.

DATES: The FAA must receive comments on this proposed AD by August 28,
2023.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:
     Federal eRulemaking Portal: Go to regulations.gov. Follow
the instructions for submitting comments.

     Mail: U.S. Department of Transportation, Docket
Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New
Jersey Avenue SE, Washington, DC 20590.
     Hand Delivery: Deliver to Mail address above between 9
a.m. and 5 p.m., Monday through Friday, except Federal holidays.
    AD Docket: You may examine the AD docket at regulations.gov under
Docket No. FAA-2023-1404; or in person at Docket Operations between 9
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD
docket contains this NPRM, the mandatory continuing airworthiness
information (MCAI), any comments received, and other information. The
street address for Docket Operations is listed above.

Background

    Transport Canada, which is the aviation authority for Canada, has
issued Transport Canada AD CF-2023-19, dated March 13, 2023 (Transport
Canada AD CF-2023-19) (also referred to after this as the MCAI), to
correct an unsafe condition on all MHI RJ Aviation ULC Model CL-600-
2B19 (Regional Jet Series 100 & 440) airplanes. The MCAI states there
was a report of a missing 12-inch piece of insulation in the 14th stage
bleed ducts installed in both left hand (LH) and right hand (RH) engine
pylon areas.
    The FAA is proposing this AD to address missing insulation in the
engine pylon area. The unsafe condition, if not addressed, could result
in the bleed duct to radiate heat to the surrounding structure and, if
not corrected, could lead to the loss of the structural integrity of
the engine pylon and possible loss of the engine. You may examine the
MCAI in the AD docket at regulations.gov under Docket No. FAA-2023-
1404.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed MHI RJ Service Bulletin 601R-54-006, Revision A,
dated May 24, 2023. This service information specifies procedures for
doing a detailed visual inspection of spar FS654.50, spar FS672.20, and
the firewall for discrepancies, including corrosion, cracks, web
waviness or flatness and damaged fasteners.
    The FAA reviewed MHI RJ Temporary Revision 2A-76, dated September
29, 2022. This service information specifies a new or more restrictive
CMR task, number C36-12-133-01, ``Detailed Visual Inspection for
missing insulation/heat shield on the 14th stage bleed duct, running
through the pylon area between FS654 and FS672.''
    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 this State of Design Authority,
it has notified the FAA of the unsafe condition described in the MCAI
and service information referenced above. The FAA is issuing this NPRM
after determining that 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, for certain airplanes, inspecting
the engine pylon structure for discrepancies and repair if necessary.
This proposed AD would also require revising the existing maintenance
or inspection program, as applicable, to incorporate a new CMR task.
    This proposed AD would require revisions to certain operator
maintenance documents to include new actions (e.g., inspections).
Compliance with these actions is required by 14 CFR 91.403(c). For
airplanes that have been previously modified, altered, or repaired in
the areas addressed by this proposed AD, the operator may not be able
to accomplish the actions described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must request
approval for an alternative method of compliance according to paragraph
(k)(1) of this proposed AD.

Differences Between This NPRM and the MCAI or Service Information

    Part I of the Transport Canada AD does not include a corrective
action requirement for the inspection of the spars and firewall
specified in MHI RJ Service Bulletin 601R-54-006, Revision A, dated May
24, 2023. Paragraph 3.B.(2) of MHI RJ Service Bulletin 601R-54-006,
Revision A, dated May 24, 2023, only specifies contacting the
manufacturer and that the manufacturer will provide additional action.
Therefore, this proposed AD specifies that corrective actions must be
done if any discrepancies are found during the inspection required by
paragraph (g) of the proposed AD.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would
affect 338 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
----------------------------------------------------------------------------------------------------------------
6 work-hours x $85 per hour = $510...........................              $0             $510         $172,380
----------------------------------------------------------------------------------------------------------------
* This table does not include the cost of revising the existing maintenance or inspection program.

    The FAA has determined that revising the existing maintenance or
inspection program takes an average of 90 work-hours per operator,
although the agency recognizes that this number may vary from operator
to operator. Since operators incorporate maintenance or inspection
program changes for their affected fleet(s), the FAA has determined
that a per-operator estimate is more accurate than a per-airplane
estimate. Therefore, the agency estimates the average total cost per
operator to be $7,650 (90 work-hours x $85 per work-hour).
    The FAA has received no definitive data on which to base the cost
estimates for the on-condition repairs specified in 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.
    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.

Extended Operations (ETOPS) of Multi-Engine Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; immediately adopted.

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

SUMMARY: The Federal Aviation Administration is amending its
regulations governing extended range operations of turbine powered
multi-engine airplanes operated by air carriers and in commuter and on-
demand passenger carrying operations. This action clarifies the
qualifications of individuals who certify by signature the ETOPS pre-
departure service check for ETOPS flights.
    This change follows current FAA guidance and clarifies the
regulations for the affected public.

DATES: This action is effective June 16, 2008.

SUPPLEMENTARY INFORMATION:

Authority for This Rulemaking

    This rulemaking is promulgated under the authority described in 49
U.S.C. 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.

Background

    The ETOPS final rule, Extended Operations (ETOPS) of Multi-Engine
Airplanes, published in the Federal Register on January 16, 2007, (72
FR 1808) applies to part 121 and part 135 turbine powered multi-engine
airplanes used in passenger-carrying, extended-range operations. All
cargo operations in airplanes with more than two engines of both part
121 and part 135 were exempted from the majority of this rule. The rule
established regulations governing the design, operation, and
maintenance of certain airplanes operated on flights involving long
distances from an adequate airport. It codified current FAA policy,
industry best practices and recommendations, and international
standards designed to ensure long range flights will continue to
operate safely. To ease the transition for current operators, the rule
included delayed compliance dates for certain ETOPS requirements.
However, as written, the final rule language does not accurately
reflect the intent of the FAA to have a qualified mechanic perform the
ETOPS pre-departure service check (PDSC) even though this intent is
clearly stated in the preamble.
    The regulatory evaluation, found in the docket of the final rule
(Docket No. 2002-6717), further substantiates the FAA's intent by using
the hourly wage rate of an aircraft mechanic as the basis for
establishing the cost of this requirement.

Good Cause Justification for Immediate Final Rule Adoption

    We find that notice and public comment under 5 U.S.C. 553(b) is
impracticable because part 121 regulation, as currently written, would
clearly require the use of mechanics with airframe and powerplant
ratings to be the only people who could certify by signature the ETOPS
pre-departure service check for ETOPS flights, even for flights outside
of the United States. As written, an operator would be required to
comply with an almost impossible requirement to have mechanics with an
airframe and powerplant rating, issued by the FAA, positioned at
numerous maintenance facilities outside of the United States. As
literally written in the final rule, this requirement is overly
burdensome and was not (1) The intent of the FAA, (2) contained in any
previous FAA guidance, and (3) contained in the notice of proposed
rulemaking for this rule.
    We find that notice and public comment under 5 U.S.C. 553(b) is
unnecessary for the amendment to part 135 regulations because this
intent is clearly stated in the preamble to the final rule. In response
to the comment ``that the check required immediately before a flight
and certified by an ETOPS qualified maintenance person is unrealistic
for part 135 operators who do not fly ETOPS routes on a regular
basis'', the FAA responded, ``The FAA disagrees that a predeparture
service check is unrealistic for 135 operators. Part 135 operators are
already required to have procedures in place to ensure that maintenance
is performed by properly qualified maintenance personnel. Allowing a
pilot to perform a PDSC degrades the importance of the check and places
a safety critical task below the level of performance required to
change a tire or replace a light bulb for reading'' (72 FR 1858,
January 16, 2007).

Discussion of the Final Rule

Clarification of Who May Certify by Signature That the ETOPS Pre-
Departure Service Check (PDSC) Has Been Completed

    Following publication of the ETOPS final rule, the FAA learned that
the qualification requirements for mechanics certifying by signature
the completion of the ETOPS PDSC did not codify existing FAA ETOPS
guidance for part 121 operators. Since 1998, FAA Advisory Circular (AC)
120-42A, Extended Range Operation with Two-Engine Airplanes (applicable
to part 121 operators) has stated, ``This check should be accomplished
and signed off by an ETOPS qualified maintenance person, immediately
prior to an ETOPS flight.''
    In the United States, this person is typically a certificated
mechanic with an airframe and powerplant rating who received adequate
airplane and engine specific training, as well as ETOPS specific
training focused on the special nature of ETOPS flights. Outside of the
United States, however, it is extremely difficult for an operator to
ensure that a

certificated mechanic with an airframe and powerplant rating performs
the pre-departure service check. In many cases, these maintenance
technicians do not possess U.S. Mechanic's Certificates with Airframe
and Powerplant Ratings. Instead, they have their country's Civil
Aviation Authority's equivalent to an airframe and powerplant rating.
The FAA does not officially recognize maintenance technicians'
certificates from other countries except in the case of the Canadian
equivalent to the U.S. Airframe and Powerplant Certificate (14 CFR
43.17).
    In order for U.S. ETOPS operators to function overseas, the FAA
consistently allowed part 121 operators to establish alternative
qualification criterion to ensure an equivalent level of safety for
maintenance technicians who conduct pre-departure service checks for
ETOPS flights. Outside the U.S., the FAA always allowed the pre-
departure service check for ETOPS flights for part 121 operators to be
accomplished and signed off by trained maintenance personnel who work
for a repair station or another part 121 operator.
    The final rule did not accurately convey the FAA's intent to codify
current practice and apply it to both part 121 and part 135 operators.
This rule clarifies FAA's intent and corrects the regulatory language
in Sec. Sec.  121.374(b)(3) and Appendix G to Part 135, section
G135.2.8(b)(3) and new (b)(4).

Continuous Airworthiness Maintenance Program (CAMP) for Two-Engine
ETOPS in Part 121

    The language in current Sec.  121.374(b)(3), as written, requires
the use of mechanics with airframe and powerplant ratings to be the
only people who can certify by signature the ETOPS pre-departure
service check for ETOPS flights, including flights outside the United
States. As written, an operator is required to comply with an almost
impossible requirement to have mechanics with an airframe and
powerplant rating, issued by the FAA, positioned at numerous
maintenance facilities outside of the United States. This requirement
is (1) overly burdensome, (2) not the intent of the FAA, and (3)
contrary to FAA guidance. The FAA has reconsidered the applicability of
this rule in consideration of existing guidance and determined that
this requirement must be consistent with existing guidance and
practice.

ETOPS Pre-Departure Service Check (PDSC) in Part 135

    The language in current Appendix G to Part 135, section
G135.2.8(b)(3), does not accurately reflect the intent of the FAA to
have a qualified maintenance person perform the ETOPS PDSC.
    The intent is clearly stated in the preamble of the final rule (72
FR 1808, January 16, 2007). In response to the public comment ``* * *
that the check required immediately before a flight and certified by an
ETOPS qualified maintenance person is unrealistic for part 135
operators who do not fly ETOPS routes on a regular basis'', the FAA
responded, ``The FAA disagrees that a pre-departure service check is
unrealistic for part 135 operators.''

Paperwork Reduction Act

    There are no new requirements for information collection associated
with these amendments.
    The FAA included a detailed discussion of the new information
collection requirements of the proposed rule at 68 FR 64782, November
14, 2003. No comments were received on these estimated requirements.

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
has identified no differences with these regulations.

Regulatory Evaluation, Regulatory Flexibility Determination,
International Trade Impact Assessment, and Unfunded Mandates Assessment

    Changes to Federal regulations must undergo several economic
analyses. First, Executive Order 12866 directs each Federal agency to
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 also requires agencies to consider international standards and,
where appropriate, use them as 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 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:
    Since this final rule merely clarifies FAA regulations covering
ETOPS flights, the expected outcome will be a minimal impact with
positive net benefits and a regulatory evaluation was not prepared.
    FAA has, therefore, determined that this final rule is not a
``significant regulatory action'' as defined in section 3(f) of
Executive Order 12866 and is not ``significant'' as defined in DOT's
Regulatory Policies and Procedures.

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 explain the
rationale for their actions to assure 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.
    This final rule merely clarifies FAA regulations covering ETOPS
flights. The expected outcome will have minimal impact on any small
entity affected by this rulemaking action.
    Therefore, as the Acting FAA Administrator, I certify that this
rule will not have a significant economic impact on a substantial
number of small entities.

International Trade Impact Assessment

    The Trade Agreements Act of 1979 (Pub. L. 96-039) prohibits Federal
agencies from establishing any standards or engaging in related
activities that create unnecessary obstacles to the foreign commerce of
the United States. Legitimate domestic objectives, such as safety, are
not considered unnecessary obstacles. The statute also requires
consideration of international standards and, where appropriate, that
they be the basis for U.S. standards.
    The requirements imposed on both domestic and foreign operators
create no obstacles to the foreign commerce of the United States. Thus,
complies with the Trade Agreements Act of 1979.

Unfunded Mandates Reform Act

    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 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 final 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, or the
relationship between the national Government and the States, or on the
distribution of power and responsibilities among the various levels of
government. Therefore, we have determined that this final rule does not
have federalism implications.

Small Business Regulatory Enforcement Fairness Act

    The Small Business Regulatory Enforcement Fairness Act (SBREFA) of
1996 requires FAA to comply with small entity requests for information
or advice about compliance with statutes and regulations within its
jurisdiction. Therefore, any small entity that has a question regarding
this document may contact their local FAA official or the person listed
under FOR FURTHER INFORMATION CONTACT heading at the beginning of the
preamble. You can find out more about SBREFA on the Internet at http://
