I. Discussion
On September 10, 2019, the Consumer
Financial Protection Bureau (Bureau or
CFPB) issued the ‘‘Policy on No-Action
Letters’’ and the ‘‘Policy on the
Compliance Assistance Sandbox’’
(Policies).1 The CFPB issued the original
version of its Policy on No-Action
Letters in February 2016.2 The Policy on
No-Action Letters set forth how
companies should submit No-Action
Letter applications and how the CFPB
would assess and issue No-Action
Letters. Under the policy, the CFPB
would grant No-Action Letters to
individual companies, advising
recipients that the agency would not
make supervisory findings or bring a
supervisory or enforcement action

against the company with respect to
certain matters.
The Policy on the Compliance
Assistance Sandbox set forth how the
CFPB would grant a company immunity
from liability under one or more of three
safe harbor provisions and provide an
approval concluding that the offering or
providing of certain aspects of an
individual company’s product or service
complies with the relevant Federal
consumer financial law.
Under the Paperwork Reduction Act
of 1995 (PRA),3 Federal agencies are
required to assess the paperwork
burdens of their information collection
activities. The PRA authorization
concerning the Policies expires
September 30, 2022. The CFPB
determined that the Policies do not
advance their stated objective of
facilitating consumer-beneficial
innovation. The CFPB also determined
that the existing Policies failed to meet
appropriate standards for transparency
and stakeholder participation. The
CFPB is developing new approaches to
facilitate the development of new
products and services.
To preserve resources and reduce
inefficiency and burden, the CFPB is not
requesting to renew the Policies’ PRA
authorizations, and the Policies are
rescinded, effective September 30, 2022.
Consistent with the PRA, as of
September 30, 2022, the CFPB will no
longer accept No-Action Letter or
Compliance Assistance Sandbox
applications submitted on a form using
OMB Control No. 3170–0059.4 The
CFPB will continue to accept and
process requests under the Trial
Disclosure Policy.5 Entities that have
made submissions under the No Action
Letter or Compliance Assistance
Sandbox Policies will be notified if the
CFPB intends to take additional steps on
such submissions.

ACTION: Final rule.
AGENCY:
The FAA is adopting a new
airworthiness directive (AD) for certain
De Havilland Aircraft of Canada Limited
Model DHC–8–400 series airplanes.
This AD was prompted by reports of
broken P-clamps on the pressure relief
line and the motive flow line in the fuel
tanks, and a subsequent determination
that certain service information lacked
instructions for maintaining appropriate
clearance between certain fuel tubes and
their support brackets, and may also
have led to incorrect installation of
certain TeflonTM sleeves. This AD was
also prompted by a determination that
new or more restrictive airworthiness
limitations are necessary. This AD
requires inspecting the motive flow line,
vent line, and related parts, and adding
support or additional clearance if
necessary. This AD also requires
inspection, and replacement or
relocation if necessary, of affected
TeflonTM sleeves on the vent line, and
installation of TeflonTM sleeves on the
vent line at additional wing stations.
This AD also requires revising the
existing maintenance or inspection

SUPPLEMENTARY INFORMATION:
Background
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued TCCA AD CF–
2017–05R2, dated September 20, 2019
(CF–2017–05R2) (also referred to after
this as the Mandatory Continuing
Airworthiness Information, or the
MCAI), to correct an unsafe condition
for certain De Havilland Aircraft of
Canada Limited Model DHC–8–400,
–401, and –402 airplanes. You may

www.regulations.gov by searching for
and locating Docket No. FAA–2022–
0287.
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain De Havilland Aircraft of
Canada Limited Model DHC–8–400
series airplanes. The NPRM published
in the Federal Register on March 24,
2022 (87 FR 16661). The NPRM was
prompted by reports of broken P-clamps
on the pressure relief line and the
motive flow line in the fuel tanks, and
a subsequent determination that certain
service information lacked instructions
for maintaining appropriate clearance
between fuel tubes and their support
brackets at wing stations –371.019 and
–209.109 in the left-hand fuel tank and
wing stations 371.019 and 209.019 in
the right-hand fuel tank. This may also
have led to incorrect installation of
certain TeflonTM sleeves. The NPRM
was also prompted by a determination
that new or more restrictive
airworthiness limitations are necessary.
The NPRM proposed to require
inspecting the motive flow line, vent
line, and related parts, and adding
support or additional clearance if
necessary. The NPRM also proposed to
require inspection, and replacement or
relocation if necessary, of affected
TeflonTM sleeves on the vent line, and
installation of TeflonTM sleeves on the
vent line at additional wing stations.
The NPRM further proposed to require
revising the existing maintenance or
inspection program, as applicable, to
incorporate new or more restrictive
airworthiness limitation. The FAA is
issuing this AD to address adverse
impacts on the integrity of the electrical
bonding paths throughout the fuel line,
which could lead to arcing between the
vent line and airplane structure, and
could result in possible fuel tank
ignition in the event of a lightning
strike. See the MCAI for additional
background information.

Comments
The FAA received comments from the
Air Line Pilots Association,

the NPRM without change.
The FAA received additional
comments from Horizon Air. The
following presents the comments
received on the NPRM and the FAA’s
response.

Horizon Air asked that paragraph (j)
of the proposed AD be revised to require
Bombardier Q400 Dash 8 Maintenance
Requirements Manual (MRM), PSM 1–
84–7, Revision 9, dated July 10, 2018.
Horizon Air stated that paragraph (j) of
the proposed AD mandates
incorporation of the information
specified in (Bombardier) Q400 Dash 8
Temporary Revision (TR) ALI–0192 and
TR ALI–0193, both dated April 24,
2018, into Section 4–28 Fuel System
Limitation, or Section 5–00 Critical
Design Configuration Control
Limitations, as applicable, of Part 2, of
the Bombardier Q400 Dash 8
Maintenance Requirements Manual,
PSM 1–84–7. Horizon Air added that
the TRs have been incorporated and the
maintenance manual is currently at
Revision 9.
The FAA agrees to clarify. Paragraph
(j) of this AD requires operators to
incorporate ‘‘the information specified
in’’ (Bombardier) Q400 Dash 8 TR ALI–
0192 and TR ALI–0193, both dated
April 24, 2018. The information is the
same in both Bombardier Q400 Dash 8
Maintenance Requirements Manual
(MRM), PSM 1–84–7, Revision 9, dated
July 10, 2018, and TR ALI–0192 and TR
ALI–0193. Therefore, if operators
incorporate Bombardier Q400 Dash 8
Maintenance Requirements Manual
(MRM), PSM 1–84–7, Revision 9, dated
July 10, 2018, into the maintenance or
inspection program, as applicable, they
are in compliance with paragraph (j) of
this AD (i.e., since the information
specified in Bombardier Q400 Dash 8
Maintenance Requirements Manual
(MRM), PSM 1–84–7, Revision 9, dated
July 10, 2018, contains the same
information as TR ALI–0192 and TR
ALI–0193, both dated April 24, 2018,
the operator is complying with the
requirement to incorporate the
information specified in the TRs). The
FAA has not changed this AD in this
regard.
The FAA has revised paragraph (h)(4)
of this AD to more accurately identify
the actions specified in that paragraph
as a method of compliance for the
actions required by paragraph (h)(2) of
this AD.
The FAA has also revised paragraphs
(h)(7) and (9) of this AD to update the
language providing credit for the actions
required by those paragraphs.
These changes have not changed the
intent of these paragraphs.

Costs of Compliance
The FAA estimates that this AD
affects 52 airplanes of U.S. registry. The
FAA estimates the following costs to
comply with this AD:
ESTIMATED COSTS FOR REQUIRED ACTIONS *
Labor cost
Parts cost
Cost per product
Up to 93 work-hours × $85 per hour = Up to $7,905 .....
Up to $7,862 ......................
Up to $15,767 ....................
Cost on U.S.
operators
Up to $819,884.
jspears on DSK121TN23PROD with RULES
* Table does not include estimated costs for revising the maintenance or inspection program.
The FAA has determined that revising
the maintenance or inspection program
takes an average of 90 work-hours per
operator, although the FAA recognizes
that this number may vary from operator
to operator. In the past, the FAA has
estimated that this action takes 1 workhour per airplane. 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 FAA estimates the total cost per
VerDate Sep<11>2014

operator to be $7,650 (90 work-hours ×
$85 per work-hour).
The FAA has received no definitive
data on which to base the cost estimates
for the on-condition actions specified in
this 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.
PO 00000
Frm 00003
Fmt 4700
Sfmt 4700
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.

Airworthiness Directives; De Havilland Aircraft of Canada Limited
(Type Certificate Previously Held by Bombardier, Inc.) Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain De Havilland Aircraft of Canada Limited Model DHC-8-400 series
airplanes. This AD was prompted by reports of broken P-clamps on the
pressure relief line and the motive flow line in the fuel tanks, and a
subsequent determination that certain service information lacked
instructions for maintaining appropriate clearance between certain fuel
tubes and their support brackets, and may also have led to incorrect
installation of certain TeflonTM sleeves. This AD was also
prompted by a determination that new or more restrictive airworthiness
limitations are necessary. This AD requires inspecting the motive flow
line, vent line, and related parts, and adding support or additional
clearance if necessary. This AD also requires inspection, and
replacement or relocation if necessary, of affected TeflonTM
sleeves on the vent line, and installation of TeflonTM
sleeves on the vent line at additional wing stations. This AD also
requires revising the existing maintenance or inspection
[[Page 58440]]
program, as applicable, to incorporate new or more restrictive
airworthiness limitations. The FAA is issuing this AD to address the
unsafe condition on these products.
DATES: This AD is effective November 1, 2022.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of November 1,
2022.

SUPPLEMENTARY INFORMATION:
Background
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2017-05R2, dated September
20, 2019 (CF-2017-05R2) (also referred to after this as the Mandatory
Continuing Airworthiness Information, or the MCAI), to correct an
unsafe condition for certain De Havilland Aircraft of Canada Limited
Model DHC-8-400, -401, and -402 airplanes. You may examine the MCAI in
the AD docket at www.regulations.gov by searching for and locating
Docket No. FAA-2022-0287.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain De Havilland
Aircraft of Canada Limited Model DHC-8-400 series airplanes. The NPRM
published in the Federal Register on March 24, 2022 (87 FR 16661). The
NPRM was prompted by reports of broken P-clamps on the pressure relief
line and the motive flow line in the fuel tanks, and a subsequent
determination that certain service information lacked instructions for
maintaining appropriate clearance between fuel tubes and their support
brackets at wing stations -371.019 and -209.109 in the left-hand fuel
tank and wing stations 371.019 and 209.019 in the right-hand fuel tank.
This may also have led to incorrect installation of certain
TeflonTM sleeves. The NPRM was also prompted by a
determination that new or more restrictive airworthiness limitations
are necessary. The NPRM proposed to require inspecting the motive flow
line, vent line, and related parts, and adding support or additional
clearance if necessary. The NPRM also proposed to require inspection,
and replacement or relocation if necessary, of affected
TeflonTM sleeves on the vent line, and installation of
TeflonTM sleeves on the vent line at additional wing
stations. The NPRM further proposed to require revising the existing
maintenance or inspection program, as applicable, to incorporate new or
more restrictive airworthiness limitation. The FAA is issuing this AD
to address adverse impacts on the integrity of the electrical bonding
paths throughout the fuel line, which could lead to arcing between the
vent line and airplane structure, and could result in possible fuel
tank ignition in the event of a lightning strike. See the MCAI for
additional background information.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from the Air Line Pilots Association,
International, (ALPA), who supported the NPRM without change.
The FAA received additional comments from Horizon Air. The
following presents the comments received on the NPRM and the FAA's
response.
Request To Specify the Latest Revision of the Maintenance Manual
Horizon Air asked that paragraph (j) of the proposed AD be revised
to require Bombardier Q400 Dash 8 Maintenance Requirements Manual
(MRM), PSM 1-84-7, Revision 9, dated July 10, 2018. Horizon Air stated
that paragraph (j) of the proposed AD mandates incorporation of the
information specified in (Bombardier) Q400 Dash 8 Temporary Revision
(TR) ALI-0192 and TR ALI-0193, both dated April 24, 2018, into Section
4-28 Fuel System Limitation, or Section 5-00 Critical Design
Configuration Control Limitations, as applicable, of Part 2, of the
Bombardier Q400 Dash 8 Maintenance Requirements Manual, PSM 1-84-7.
Horizon Air added that the TRs have been incorporated and the
maintenance manual is currently at Revision 9.
The FAA agrees to clarify. Paragraph (j) of this AD requires
operators to incorporate ``the information specified in'' (Bombardier)
Q400 Dash 8 TR ALI-0192 and TR ALI-0193, both dated April 24, 2018. The
information is the same in both Bombardier Q400 Dash 8 Maintenance
Requirements Manual (MRM), PSM 1-84-7, Revision 9, dated July 10, 2018,
and TR ALI-0192 and TR ALI-0193. Therefore, if operators incorporate
Bombardier Q400 Dash 8 Maintenance Requirements Manual (MRM), PSM 1-84-
7, Revision 9, dated July 10, 2018, into the maintenance or inspection
program, as applicable, they are in compliance with paragraph (j) of
this AD (i.e., since the information specified in Bombardier Q400 Dash
8 Maintenance Requirements Manual (MRM), PSM 1-84-7, Revision 9, dated
July 10, 2018, contains the same information as TR ALI-0192 and TR ALI-
0193, both dated April 24, 2018, the operator is complying with the
requirement to incorporate the information specified in the TRs). The
FAA has not changed this AD in this regard.
Changes Made to This AD
The FAA has revised paragraph (h)(4) of this AD to more accurately
identify the actions specified in that paragraph as a method of
compliance for the actions required by paragraph (h)(2) of this AD.
The FAA has also revised paragraphs (h)(7) and (9) of this AD to
update the language providing credit for the actions required by those
paragraphs.
These changes have not changed the intent of these paragraphs.
[[Page 58441]]
Conclusion
The FAA reviewed the relevant data and determined that air safety
requires adopting this AD as proposed. Except for minor editorial
changes, and any other changes described previously, this AD is adopted
as proposed in the NPRM. None of the changes will increase the economic
burden on any operator. Accordingly, the FAA is issuing this AD to
address the unsafe condition on these products.

Costs of Compliance
The FAA estimates that this AD affects 52 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions *
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 93 work-hours x $85 per hour = Up to $7,862........... Up to $15,767.......... Up to $819,884.
Up to $7,905.
----------------------------------------------------------------------------------------------------------------
* Table does not include estimated costs for revising the maintenance or inspection program.
The FAA has determined that revising the maintenance or inspection
program takes an average of 90 work-hours per operator, although the
FAA recognizes that this number may vary from operator to operator. In
the past, the FAA has estimated that this action takes 1 work-hour per
airplane. 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 FAA estimates the 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 actions specified in this 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.
