Discussion
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian AD
CF–2019–21, dated May 15, 2019
(referred to after this as the Mandatory
Continuing Airworthiness Information,
or ‘‘the MCAI’’), to correct an unsafe
condition for certain Bombardier, Inc.,
Model CL–600–2B19 (Regional Jet
Series 100 & 440) airplanes. You may
examine the MCAI in the AD docket on
the internet at https://
www.regulations.gov by searching for
and locating Docket No. FAA–2019–
0987.
This proposed AD was prompted by
reports that during airplane wing fatigue
testing, fatigue cracks were found on the
lower right-hand-side wing plank at the
end of the integrally machined stringers,
which led to a determination that new
or more restrictive airworthiness
limitations are necessary. The FAA is
proposing this AD to address
undetected cracks on the lower wing
plank at the stringer run-out, which
could affect the structural integrity of
the wing. See the MCAI for additional
background information.
Related Service Information Under 1
CFR Part 51
Bombardier has issued
Nondestructive Testing Manual, CSP A–
010, Revision 40, dated November 10,
2018. This service information describes
airworthiness limitations for doing a
special detailed inspection of the lower
wing skin splice joints at buttock line
(BL) 45.00, wing station (WS) 65.75, and
WS148.00. Bombardier has also issued
Temporary Revision 2B–2273, dated
October 31, 2019, to Appendix B—
Airworthiness Limitations, of Part 2 of
the Bombardier CL–600–2B19
Maintenance Requirements Manual.
This service information describes
airworthiness limitations for doing an
inspection for cracking on the lower

wing plank at the stringer run-out. 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
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 Requirements of This NPRM
This proposed AD would require
revising the existing maintenance or
inspection program, as applicable, to
incorporate new or more restrictive
airworthiness limitations.
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 (j)(1) of this proposed AD.
Differences Between This Proposed AD
and the MCAI
Paragraph (h) of this proposed AD
would require revising the
maintenance/inspection program to
incorporate Airworthiness Limitations
(AWL) Task 57–21–169 for certain
airplanes. The corresponding MCAI
requirement specifies incorporating this
task using Bombardier Temporary
Revision 2B–2269, dated July 18, 2018,
to Appendix B—Airworthiness
Limitations, of Part 2 of the Bombardier
CL–600–2B19 Maintenance
Requirements Manual. However, since
the MCAI was issued, that service
information has been revised to
Temporary Revision 2B–2273, dated
October 31, 2019 (‘‘Temporary Revision
2B–2273’’). Temporary Revision 2B–
2273 defines the compliance time
threshold, which begins from the time
the airplane entered into service. This
E:\FR\FM\27DEP1.SGM
27DEP1
Federal Register / Vol. 84, No. 248 / Friday, December 27, 2019 / Proposed Rules
proposed AD would require
incorporating Temporary Revision 2B–
2273.
jbell on DSKJLSW7X2PROD with PROPOSALS
Costs of Compliance
The FAA estimates that this proposed
AD affects 464 airplanes of U.S. registry.
The FAA estimates the following costs
to comply with this proposed AD:
The FAA has determined that revising
the existing maintenance or inspection
program takes an average of 90 workhours 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 × $85 per work-hour).
According to the manufacturer, some
or all of the costs of this proposed AD
may be covered under warranty, thereby
reducing the cost impact on affected
individuals. The FAA does not control
warranty coverage for affected
individuals. As a result, the FAA has
included all known costs in the cost
estimate.
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.
This proposed AD is issued in
accordance with authority delegated by
the Executive Director, Aircraft
Certification Service, as authorized by
FAA Order 8000.51C. In accordance
with that order, issuance of ADs is
normally a function of the Compliance
and Airworthiness Division, but during
this transition period, the Executive
Director has delegated the authority to
VerDate Sep<11>2014
17:34 Dec 26, 2019
Jkt 250001
issue ADs applicable to transport
category airplanes and associated
appliances to the Director of the System
Oversight Division.
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) Will not affect intrastate aviation
in Alaska, and
(3) Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.
List of Subjects in 14 CFR Part 39

Airworthiness Directives; 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 certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series
100 & 440) airplanes. This proposed AD was prompted by reports that
during airplane wing fatigue testing, fatigue cracks were found on the
lower right-hand-side wing plank at the end of the integrally machined
stringers, which led to a determination that new or more restrictive
airworthiness limitations are necessary. This proposed AD would
require, for certain airplanes, revising the existing maintenance or
inspection program, as applicable, to incorporate new or more
restrictive airworthiness limitations. The FAA is proposing this
[[Page 71336]]
AD to address the unsafe condition on these products.

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2019-21, dated May 15,
2019 (referred to after this as the Mandatory Continuing Airworthiness
Information, or ``the MCAI''), to correct an unsafe condition for
certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 &
440) airplanes. You may examine the MCAI in the AD docket on the
internet at https://www.regulations.gov by searching for and locating
Docket No. FAA-2019-0987.
This proposed AD was prompted by reports that during airplane wing
fatigue testing, fatigue cracks were found on the lower right-hand-side
wing plank at the end of the integrally machined stringers, which led
to a determination that new or more restrictive airworthiness
limitations are necessary. The FAA is proposing this AD to address
undetected cracks on the lower wing plank at the stringer run-out,
which could affect the structural integrity of the wing. See the MCAI
for additional background information.
Related Service Information Under 1 CFR Part 51
Bombardier has issued Nondestructive Testing Manual, CSP A-010,
Revision 40, dated November 10, 2018. This service information
describes airworthiness limitations for doing a special detailed
inspection of the lower wing skin splice joints at buttock line (BL)
45.00, wing station (WS) 65.75, and WS148.00. Bombardier has also
issued Temporary Revision 2B-2273, dated October 31, 2019, to Appendix
B--Airworthiness Limitations, of Part 2 of the Bombardier CL-600-2B19
Maintenance Requirements Manual. This service information describes
airworthiness limitations for doing an inspection for cracking on the
lower wing plank at the stringer run-out. 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 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 Requirements of This NPRM
This proposed AD would require revising the existing maintenance or
inspection program, as applicable, to incorporate new or more
restrictive airworthiness limitations.
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
(j)(1) of this proposed AD.
Differences Between This Proposed AD and the MCAI
Paragraph (h) of this proposed AD would require revising the
maintenance/inspection program to incorporate Airworthiness Limitations
(AWL) Task 57-21-169 for certain airplanes. The corresponding MCAI
requirement specifies incorporating this task using Bombardier
Temporary Revision 2B-2269, dated July 18, 2018, to Appendix B--
Airworthiness Limitations, of Part 2 of the Bombardier CL-600-2B19
Maintenance Requirements Manual. However, since the MCAI was issued,
that service information has been revised to Temporary Revision 2B-
2273, dated October 31, 2019 (``Temporary Revision 2B-2273'').
Temporary Revision 2B-2273 defines the compliance time threshold, which
begins from the time the airplane entered into service. This
[[Page 71337]]
proposed AD would require incorporating Temporary Revision 2B-2273.
Costs of Compliance
The FAA estimates that this proposed AD affects 464 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
The FAA has determined that revising the existing 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).
According to the manufacturer, some or all of the costs of this
proposed AD may be covered under warranty, thereby reducing the cost
impact on affected individuals. The FAA does not control warranty
coverage for affected individuals. As a result, the FAA has included
all known costs in the cost estimate.
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.
This proposed AD is issued in accordance with authority delegated
by the Executive Director, Aircraft Certification Service, as
authorized by FAA Order 8000.51C. In accordance with that order,
issuance of ADs is normally a function of the Compliance and
Airworthiness Division, but during this transition period, the
Executive Director has delegated the authority to issue ADs applicable
to transport category airplanes and associated appliances to the
Director of the System Oversight Division.
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) Will not affect intrastate aviation in Alaska, and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
